From eye exams to blood tests and surgery: how doctors use light to diagnose disease

<p><em><a href="https://theconversation.com/profiles/matthew-griffith-1539353">Matthew Griffith</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>You’re not feeling well. You’ve had a pounding headache all week, dizzy spells and have vomited up your past few meals.</p> <p>You visit your GP to get some answers and sit while they shine a light in your eyes, order a blood test and request some medical imaging.</p> <p>Everything your GP just did relies on light. These are just some of the optical technologies that have had an enormous impact in how we diagnose disease.</p> <h2>1. On-the-spot tests</h2> <p>Point-of-care diagnostics allow doctors to test patients on the spot and get answers in minutes, rather than sending samples to a lab for analysis.</p> <p>The “flashlight” your GP uses to view the inside of your eye (known as an <a href="https://medlineplus.gov/ency/article/003881.htm">ophthalmoscope</a>) is a great example. This allows doctors to detect abnormal blood flow in the eye, deformations of the cornea (the outermost clear layer of the eye), or swollen optical discs (a round section at the back of the eye where the nerve link to the brain begins). Swollen discs are a sign of elevated pressure inside your head (or in the worst case, a brain tumour) that could be <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/headache/increased-intracranial-pressure-icp-headache">causing your headaches</a>.</p> <p>The invention of <a href="https://openmedscience.com/lighting-the-way-in-healthcare-the-transformative-role-of-lasers-in-medicine/">lasers and LEDs</a> has enabled many other miniaturised technologies to be provided at the bedside or clinic rather than in the lab.</p> <p><a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">Pulse oximetry</a> is a famous example, where a clip attached to your finger reports how well your blood is oxygenated. It does this by <a href="https://www.howequipmentworks.com/pulse_oximeter/">measuring</a> the different responses of oxygenated and de-oxygenated blood to different colours of light.</p> <p>Pulse oximetry is used at hospitals (and <a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">sometimes at home</a>) to monitor your respiratory and heart health. In hospitals, it is also a valuable tool for detecting <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60107-X/fulltext">heart defects in babies</a>.</p> <h2>2. Looking at molecules</h2> <p>Now, back to that blood test. Analysing a small amount of your blood can diagnose <a href="https://theconversation.com/blood-tests-and-diagnosing-illness-what-can-blood-tell-us-about-whats-happening-in-our-body-80327">many different diseases</a>.</p> <p>A machine called an automated “full blood count analyser” tests for general markers of your health. This machine directs focused beams of light through blood samples held in small glass tubes. It counts the number of blood cells, determines their specific type, and reports the level of haemoglobin (the protein in red blood cells that distributes oxygen around your body). In minutes, this machine can provide a <a href="https://www.nuffieldhealth.com/article/inside-the-pathology-lab-what-happens-to-my-blood">snapshot</a> of your overall health.</p> <p>For more specific disease markers, blood serum is separated from the heavier cells by spinning in a rotating instrument called a centrifuge. The serum is then exposed to special chemical stains and enzyme assays that change colour depending on whether specific molecules, which may be the sign of a disease, are present.</p> <p>These colour changes can’t be detected with the naked eye. However, a light beam from an instrument called a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5476943/#R88">spectrometer</a> can detect tiny amounts of these substances in the blood and determine if the biomarkers for diseases are present, and at what levels.</p> <h2>3. Medical imaging</h2> <p>Let’s re-visit those medical images your GP ordered. The development of fibre-optic technology, made famous for transforming high-speed digital communications (such as the NBN), allows light to get inside the body. The result? High-resolution optical imaging.</p> <p>A common example is an <a href="https://www.medicalnewstoday.com/articles/153737#risks-and-side-effects">endoscope</a>, where fibres with a tiny camera on the end are inserted into the body’s natural openings (such as your mouth or anus) to examine your gut or respiratory tracts.</p> <p>Surgeons can insert the same technology through tiny cuts to view the inside of the body on a video screen during <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9553337/">laparoscopic surgery</a> (also known as keyhole surgery) to diagnose and treat disease.</p> <h2>How about the future?</h2> <p>Progress in nanotechnology and a better understanding of the interactions of light with our tissues are leading to new light-based tools to help diagnose disease. These include:</p> <ul> <li> <p><a href="https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201903441">nanomaterials</a> (materials on an extremely small scale, many thousands of times smaller than the width of a human hair). These are being used in next-generation sensors and new diagnostic tests</p> </li> <li> <p><a href="https://www.nature.com/articles/s41587-019-0045-y">wearable optical biosensors</a> the size of your fingernail can be included in devices such as watches, contact lenses or finger wraps. These devices allow non-invasive measurements of sweat, tears and saliva, in real time</p> </li> <li> <p>AI tools to analyse how blood serum scatters infrared light. This has allowed researchers to build a <a href="https://www.advancedsciencenews.com/powerful-diagnostic-approach-uses-light-to-detect-virtually-all-forms-of-cancer/">comprehensive database</a> of scatter patterns to detect <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/aisy.202300006">any cancer</a></p> </li> <li> <p>a type of non-invasive imaging called <a href="https://www.ncbi.nlm.nih.gov/books/NBK554044/">optical coherence tomography</a> for more detailed imaging of the eye, heart and skin</p> </li> <li> <p>fibre optic technology to deliver a tiny microscope into the body on the <a href="https://www.uwa.edu.au/projects/microscope-in-a-needle">tip of a needle</a>.</p> </li> </ul> <p>So the next time you’re at the GP and they perform (or order) some tests, chances are that at least one of those tests depend on light to help diagnose disease.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231379/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/matthew-griffith-1539353"><em>Matthew Griffith</em></a><em>, Associate Professor and ARC Future Fellow and Director, UniSA Microscopy and Microanalysis Facilities, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How light can shift your mood and mental health

<p><em><a href="https://theconversation.com/profiles/jacob-crouse-981668">Jacob Crouse</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/emiliana-tonini-1638957">Emiliana Tonini</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ian-hickie-961">Ian Hickie</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>It’s spring and you’ve probably noticed a change in when the Sun rises and sets. But have you also noticed a change in your mood?</p> <p>We’ve known for a while that light plays a role in our wellbeing. Many of us tend to feel more positive when <a href="https://pubmed.ncbi.nlm.nih.gov/32925966/">spring returns</a>.</p> <p>But for others, big changes in light, such as at the start of spring, can be tough. And for many, bright light at night can be a problem. Here’s what’s going on.</p> <h2>An ancient rhythm of light and mood</h2> <p>In an <a href="https://theconversation.com/how-light-tells-you-when-to-sleep-focus-and-poo-236780">earlier article</a> in our series, we learned that light shining on the back of the eye sends “<a href="https://pubmed.ncbi.nlm.nih.gov/25451984/">timing signals</a>” to the brain and the master clock of the circadian system. This clock coordinates our daily (circadian) rhythms.</p> <p>“Clock genes” also regulate circadian rhythms. These genes control the timing of when many other genes <a href="https://pubmed.ncbi.nlm.nih.gov/31557726/">turn on and off</a> during the 24-hour, light-dark cycle.</p> <p>But how is this all linked with our mood and mental health?</p> <p>Circadian rhythms can be disrupted. This can happen if there are problems with how the body clock develops or functions, or if someone is routinely exposed to bright light at night.</p> <p>When circadian disruption happens, it increases the risk of certain <a href="https://pubmed.ncbi.nlm.nih.gov/33689801/">mental disorders</a>. These include <a href="https://www.sciencedirect.com/science/article/abs/pii/S0149763422000744">bipolar disorder</a> and <a href="https://bmcmedicine.biomedcentral.com/articles/10.1186/1741-7015-11-79">atypical depression</a> (a type of depression when someone is extra sleepy and has problems with their energy and metabolism).</p> <h2>Light on the brain</h2> <p>Light may also affect circuits <a href="https://pubmed.ncbi.nlm.nih.gov/35687680/">in the brain</a> that control mood, as <a href="https://pubmed.ncbi.nlm.nih.gov/23151476/">animal studies show</a>.</p> <p>There’s evidence this happens in humans. A brain-imaging study showed exposure to bright light in the daytime while inside the scanner <a href="https://www.cell.com/fulltext/S0960-9822(06)01758-1">changed the activity</a> of a brain region involved in mood and alertness.</p> <p>Another brain-imaging study <a href="https://pubmed.ncbi.nlm.nih.gov/22111663/">found</a> a link between daily exposure to sunlight and how the neurotransmitter (or chemical messenger) serotonin binds to receptors in the brain. We see alterations in serotonin binding in several <a href="https://pubmed.ncbi.nlm.nih.gov/33651238/">mental disorders</a>, including depression.</p> <h2>What happens when the seasons change?</h2> <p>Light can also affect mood and mental health as the seasons change. During autumn and winter, symptoms such as low mood and fatigue can develop. But often, once spring and summer come round, these symptoms go away. This is called “seasonality” or, when severe, “<a href="https://www.aafp.org/pubs/afp/issues/2020/1201/p668.html">seasonal affective disorder</a>”.</p> <p>What is less well known is that for other people, the change to spring and summer (when there is <em>more</em> light) can also come with a change in mood and mental health. Some people experience increases in energy and the drive to be active. This is positive for some but can be seriously destabilising for others. This too is an example of seasonality.</p> <p>Most people <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0239033">aren’t very seasonal</a>. But for those who are, seasonality has a <a href="https://pubmed.ncbi.nlm.nih.gov/8540777/">genetic component</a>. Relatives of people with seasonal affective disorder are more likely to also experience seasonality.</p> <p>Seasonality is also more common in conditions such as <a href="https://pubmed.ncbi.nlm.nih.gov/25063960/">bipolar disorder</a>. For many people with such conditions, the shift into shorter day-lengths during winter can trigger a depressive episode.</p> <p>Counterintuitively, the longer day-lengths in spring and summer can also destabilise people with bipolar disorder into an “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10947388/">activated</a>” state where energy and activity are in overdrive, and symptoms are harder to manage. So, seasonality can be serious.</p> <p>Alexis Hutcheon, who experiences seasonality and helped write this article, told us:</p> <blockquote> <p>[…] the season change is like preparing for battle – I never know what’s coming, and I rarely come out unscathed. I’ve experienced both hypomanic and depressive episodes triggered by the season change, but regardless of whether I’m on the ‘up’ or the ‘down’, the one constant is that I can’t sleep. To manage, I try to stick to a strict routine, tweak medication, maximise my exposure to light, and always stay tuned in to those subtle shifts in mood. It’s a time of heightened awareness and trying to stay one step ahead.</p> </blockquote> <h2>So what’s going on in the brain?</h2> <p>One explanation for what’s going on in the brain when mental health fluctuates with the change in seasons relates to the neurotransmitters serotonin and dopamine.</p> <p>Serotonin helps regulate mood and is the target of <a href="https://journals.sagepub.com/doi/full/10.1177/0706743716659417">many</a> <a href="https://pubmed.ncbi.nlm.nih.gov/38185236/">antidepressants</a>. There is some evidence of seasonal changes in serotonin levels, potentially being lower <a href="https://academic.oup.com/brain/article/139/5/1605/2468755?login=false">in</a> <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(02)11737-5/abstract?cc=y%3D">winter</a>.</p> <p>Dopamine is a neurotransmitter involved in reward, motivation and movement, and is also a target of some <a href="https://journals.sagepub.com/doi/full/10.1177/0706743716659417">antidepressants</a>. Levels of dopamine may also change with the <a href="https://www.nature.com/articles/s41398-023-02365-x">seasons</a>.</p> <p>But the neuroscience of seasonality is a developing area and more research <a href="https://www.nature.com/articles/s41398-023-02365-x">is needed</a> to know what’s going on in the brain.</p> <h2>How about bright light at night?</h2> <p>We know exposure to bright light at night (for instance, if someone is up all night) can disturb someone’s circadian rhythms.</p> <p>This type of circadian rhythm disturbance is associated with higher rates of symptoms <a href="https://www.nature.com/articles/s44220-023-00135-8">including</a> self-harm, depressive and anxiety symptoms, and lower wellbeing. It is also associated with higher rates of <a href="https://pubmed.ncbi.nlm.nih.gov/32639562/">mental disorders</a>, such as major depression, bipolar disorder, psychotic disorders and post-traumatic stress disorder (or PTSD).</p> <p>Why is this? Bright light at night confuses and destabilises the body clock. It disrupts the rhythmic regulation of mood, cognition, appetite, metabolism and <a href="https://pubmed.ncbi.nlm.nih.gov/38214638/">many</a> <a href="https://pubmed.ncbi.nlm.nih.gov/34419186/">other</a> <a href="https://pubmed.ncbi.nlm.nih.gov/33689801/">mental</a> <a href="https://pubmed.ncbi.nlm.nih.gov/36661342/">processes</a>.</p> <p>But people differ hugely in their <a href="https://www.pnas.org/doi/10.1073/pnas.1901824116">sensitivity to light</a>. While still a hypothesis, people who are most sensitive to light may be the most vulnerable to body clock disturbances caused by bright light at night, which then leads to a higher risk of mental health problems.</p> <h2>Where to from here?</h2> <p>Learning about light will help people better manage their mental health conditions.</p> <p>By encouraging people to better align their lives to the light-dark cycle (to stabilise their body clock) we may also help prevent conditions such as <a href="https://pubmed.ncbi.nlm.nih.gov/34419186/">depression</a> and <a href="https://www.sciencedirect.com/science/article/pii/S0149763422000744">bipolar disorder</a> emerging in the first place.</p> <p>Healthy light behaviours – avoiding light at night and seeking light during the day – are good for everyone. But they might be especially helpful for people <a href="https://www.sciencedirect.com/science/article/pii/S0149763422000744">at risk</a> of mental health problems. These include people with a family history of mental health problems or people who are <a href="https://pubmed.ncbi.nlm.nih.gov/38185236/">night owls</a> (late sleepers and late risers), who are more at risk of body clock disturbances.</p> <hr /> <p><em>Alexis Hutcheon has lived experience of a mental health condition and helped write this article.</em></p> <p><em>If this article has raised issues for you, or if you’re concerned about someone you know, call Lifeline on 13 11 14.</em><img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231282/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/jacob-crouse-981668"><em>Jacob Crouse</em></a><em>, Research Fellow in Youth Mental Health, Brain and Mind Centre, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/emiliana-tonini-1638957">Emiliana Tonini</a>, Postdoctoral Research Fellow, Brain and Mind Centre, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ian-hickie-961">Ian Hickie</a>, Co-Director, Health and Policy, Brain and Mind Centre, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image </em><em>credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How light tells you when to sleep, focus and poo

<p><em><a href="https://theconversation.com/profiles/frederic-gachon-1379094">Frederic Gachon</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/benjamin-weger-1646210">Benjamin Weger</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Exposure to light is crucial for our physical and mental health, as this and future articles in the series will show.</p> <p>But the <em>timing</em> of that light exposure is also crucial. This tells our body to wake up in the morning, when to poo and the time of day to best focus or be alert. When we’re exposed to light also controls our body temperature, blood pressure and even chemical reactions in our body.</p> <p>But how does our body know when it’s time to do all this? And what’s light got to do with it?</p> <h2>What is the body clock, actually?</h2> <p>One of the key roles of light is to re-set our body clock, also known as the circadian clock. This works like an internal oscillator, similar to an actual clock, ticking away as you read this article.</p> <p>But rather than ticking you can hear, the body clock is a network of genes and proteins that regulate each other. This network sends signals to organs via hormones and the nervous system. These complex loops of interactions and communications have a rhythm of about 24 hours.</p> <p>In fact, we don’t have one clock, we have trillions of body clocks throughout the body. The central clock is in the hypothalamus region of the brain, and each cell in every organ has its own. These clocks work in concert to help us adapt to the daily cycle of light and dark, aligning our body’s functions with the time of day.</p> <p>However, our body clock is not precise and works to a rhythm of <em>about</em> 24 hours (24 hours 30 minutes on average). So every morning, the central clock needs to be reset, signalling the start of a new day. This is why light is so important.</p> <p>The central clock is directly connected to <a href="https://journals.sagepub.com/doi/abs/10.1177/07487304231225706">light-sensing cells</a> in our retinas (the back of the eye). This daily re-setting of the body clock with morning light is essential for ensuring our body works well, in sync with our environment.</p> <p>In parallel, <a href="https://theconversation.com/does-it-matter-what-time-of-day-i-eat-and-can-intermittent-fasting-improve-my-health-heres-what-the-science-says-203762">when we eat food</a> also plays a role in re-setting the body clock, but this time the clock in organs other than the brain, such as the liver, kidneys or the gut.</p> <p>So it’s easy to see how our daily routines are closely linked with our body clocks. And in turn, our body clocks shape how our body works at set times of the day.</p> <h2>What time of day?</h2> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Matt Garrow/The Conversation.</span> <span class="attribution"><a class="source" href="https://delos.com/blog/why-natural-light-is-important-for-mental-and-physical-health/">Adapted from Delos</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></span></figcaption></figure> <h2>Let’s take a closer look at sleep</h2> <p>The naturally occurring brain hormone <a href="https://pubmed.ncbi.nlm.nih.gov/30311830/">melatonin</a> is linked to our central clock and makes us feel sleepy at certain times of day. When it’s light, our body stops making melatonin (its production is inhibited) and we are alert. Closer to bedtime, the hormone is made, then secreted, making us feel drowsy.</p> <p>Our sleep is also <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2019.00944/full">partly controlled</a> by <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-genom-121222-120306">our genes</a>, which are part of our central clock. These genes influence our <a href="https://theconversation.com/does-it-matter-what-time-i-go-to-bed-198146">chronotype</a> – whether we are a “lark” (early riser), “night owl” (late sleeper) or a “dove” (somewhere in between).</p> <p>But exposure to light at night when we are supposed to be sleeping can have harmful effects. Even dim light from light pollution can impair our <a href="https://www.pnas.org/doi/10.1073/pnas.2113290119">heart rate and how we metabolise sugar</a> (glucose), may lead to <a href="https://doi.org/10.1038/s44220-023-00135-8">psychiatric disorders</a> such as depression, anxiety and bipolar disorder, and increases the overall risk of <a href="https://www.pnas.org/doi/10.1073/pnas.2405924121">premature death</a>.</p> <p>The main reason for these harmful effects is that light “at the wrong time” disturbs the body clock, and these effects are more pronounced for “night owls”.</p> <p>This “misaligned” exposure to light is also connected to the detrimental health effects we often see in people who <a href="https://theconversation.com/why-does-night-shift-increase-the-risk-of-cancer-diabetes-and-heart-disease-heres-what-we-know-so-far-190652">work night shifts</a>, such as an increased risk of cancer, diabetes and heart disease.</p> <h2>How about the gut?</h2> <p>Digestion also follows a circadian rhythm. Muscles in the colon that help move waste <a href="https://doi.org/10.1111/j.1572-0241.2004.40453.x">are more active</a> during the day and slow down at night.</p> <p>The most significant increase in colon movement starts at 6.30am. This is one of the reasons why most people feel the urge to poo <a href="https://theconversation.com/why-do-i-poo-in-the-morning-a-gut-expert-explains-229624">in the early morning</a> rather than at night.</p> <p>The gut’s day-night rhythm is a direct result of the action of the gut’s own clock and the central clock (which synchronises the gut with the rest of the body). It’s also influenced by when we eat.</p> <h2>How about focusing?</h2> <p>Our body clock also helps control our attention and alertness levels by changing how our brain functions at certain times of day. Attention and alertness levels improve in the afternoon and evening but dip during the night and early morning.</p> <p>Those fluctuations <a href="https://www.frontiersin.org/journals/molecular-neuroscience/articles/10.3389/fnmol.2012.00050/full">impact performance</a> and can lead to decreased productivity and an <a href="https://www.nature.com/articles/s41598-019-40914-x">increased risk</a> of errors and accidents during the less-alert hours.</p> <p>So it’s important to perform certain tasks that <a href="https://pubmed.ncbi.nlm.nih.gov/30923475/">require our attention</a> at certain times of day. That includes driving. In fact, disruption of the circadian clock at the start of daylight savings – when our body hasn’t had a chance to adapt to the clocks changing – <a href="https://www.sciencedirect.com/science/article/pii/S0960982219316781?via%3Dihub">increases the risk</a> of a car accident, particularly in the morning.</p> <h2>What else does our body clock control?</h2> <p>Our body clock influences many other aspects of our biology, including:</p> <ul> <li><strong>physical performance</strong> by controlling the activity of our <a href="https://doi.org/10.1038/s41574-023-00805-8">muscles</a></li> <li><strong>blood pressure</strong> by controlling the <a href="https://theconversation.com/what-time-of-day-should-i-take-my-medicine-125809">system of hormones</a> involved in regulating our blood volume and blood vessels</li> <li><strong>body temperature</strong> by controlling our metabolism and our level of physical activity</li> <li><strong>how our body handles drugs and toxins</strong> by <a href="https://doi.org/10.1080/17460441.2023.2224554">controlling enzymes</a> involved in how the liver and kidneys eliminate these substances from the body.</li> </ul> <h2>Morning light is important</h2> <p>But what does this all mean for us? Exposure to light, especially in the morning, is crucial for synchronising our circadian clock and bodily functions.</p> <p>As well as setting us up for a good night’s sleep, increased morning light exposure benefits our <a href="https://www.sciencedirect.com/science/article/pii/S0165032721008612?via%3Dihub">mental health</a> and <a href="https://academic.oup.com/jcem/article/101/9/3539/2806883">reduces the risk of obesity</a>. So boosting our exposure to morning light – for example, by going for a walk, or having breakfast outside – can directly benefit our mental and metabolic health.</p> <p>However, there are other aspects about which we have less control, including <a href="https://www.sciencedirect.com/science/article/pii/S0168952524001100">the genes</a> that control our body clock.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236780/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/frederic-gachon-1379094">Frederic Gachon</a>, Associate Professor, Physiology of Circadian Rhythms, Institute for Molecular Bioscience, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/benjamin-weger-1646210">Benjamin Weger</a>, NHMRC Emerging Leadership Fellow Institute for Molecular Bioscience, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Yes, blue light from your phone can harm your skin. A dermatologist explains

<p><em><a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>Social media is full of claims that everyday habits can harm your skin. It’s also full of recommendations or advertisements for products that can protect you.</p> <p>Now social media has blue light from our devices in its sights.</p> <p>So can scrolling on our phones really damage your skin? And will applying creams or lotions help?</p> <p>Here’s what the evidence says and what we should really be focusing on.</p> <h2>Remind me, what actually is blue light?</h2> <p>Blue light is part of the visible light spectrum. Sunlight is the strongest source. But our electronic devices – such as our phones, laptops and TVs – also emit it, albeit at levels <a href="https://melasmaclinic.com.au/wp-content/uploads/2024/01/Melasma-LEDS.pdf">100-1,000 times</a> lower.</p> <p>Seeing as we spend so much time using these devices, there has been some concern about the impact of blue light on our health, including <a href="https://theconversation.com/do-blue-light-glasses-really-work-can-they-reduce-eye-strain-or-help-me-sleep-213145">on our eyes and sleep</a>.</p> <p>Now, we’re learning more about the impact of blue light on our skin.</p> <h2>How does blue light affect the skin?</h2> <p>The evidence for blue light’s impact on skin is still emerging. But there are some interesting findings.</p> <p><strong>1. Blue light can increase pigmentation</strong></p> <p><a href="https://academic.oup.com/ced/article-abstract/46/5/934/6598472?redirectedFrom=fulltext&amp;login=false">Studies</a> <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/srt.13401">suggest</a> exposure to blue light can stimulate production of melanin, the natural skin pigment that gives skin its colour.</p> <p>So too much blue light can potentially worsen hyperpigmentation – overproduction of melanin leading to dark spots on the skin – especially in people with darker skin.</p> <p><strong>2. Blue light can give you wrinkles</strong></p> <p>Some research <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6280109/">suggests</a> blue light might damage collagen, a protein essential for skin structure, potentially accelerating the formation of wrinkles.</p> <p>A laboratory <a href="https://pubmed.ncbi.nlm.nih.gov/29399830/">study suggests</a> this can happen if you hold your device one centimetre from your skin for as little as an hour.</p> <p>However, for most people, if you hold your device more than 10cm away from your skin, that would reduce your exposure <a href="https://en.wikipedia.org/wiki/Inverse-square_law">100-fold</a>. So this is much less likely to be significant.</p> <p><strong>3. Blue light can disrupt your sleep, affecting your skin</strong></p> <p>If the skin around your eyes looks dull or puffy, it’s easy to blame this directly on blue light. But as we know blue light affects sleep, what you’re probably seeing are some of the visible signs of sleep deprivation.</p> <p>We know blue light is particularly good at <a href="https://journals.physiology.org/doi/full/10.1152/japplphysiol.01413.2009?rss=1">suppressing</a> production of melatonin. This natural hormone normally signals to our bodies when it’s time for sleep and helps regulate our sleep-wake cycle.</p> <p>By suppressing melatonin, blue light exposure before bed disrupts this natural process, making it harder to fall asleep and potentially reducing the <a href="https://www.tandfonline.com/doi/abs/10.1080/07420528.2023.2173606">quality of your sleep</a>.</p> <p>The stimulating nature of screen content further disrupts sleep. Social media feeds, news articles, video games, or even work emails can keep our brains active and alert, hindering the transition into a sleep state.</p> <p>Long-term sleep problems can also <a href="https://academic.oup.com/ced/article-abstract/40/1/17/6621145?login=false">worsen</a> existing skin conditions, such as acne, eczema and rosacea.</p> <p>Sleep deprivation can elevate cortisol levels, a stress hormone that breaks down collagen, the protein responsible for skin’s firmness. Lack of sleep can also weaken the skin’s natural barrier, making it more susceptible to environmental damage and dryness.</p> <h2>Can skincare protect me?</h2> <p>The beauty industry has capitalised on concerns about blue light and offers a range of protective products such as mists, serums and lip glosses.</p> <p>From a practical perspective, probably only those with the more troublesome hyperpigmentation known as <a href="https://dermnetnz.org/topics/melasma">melasma</a> need to be concerned about blue light from devices.</p> <p>This condition requires the skin to be well protected from all visible light at all times. The only products that are totally effective are those that block all light, namely mineral-based suncreens or some cosmetics. If you can’t see the skin through them they are going to be effective.</p> <p>But there is a lack of rigorous testing for non-opaque products outside laboratories. This makes it difficult to assess if they work and if it’s worth adding them to your skincare routine.</p> <h2>What can I do to minimise blue light then?</h2> <p>Here are some simple steps you can take to minimise your exposure to blue light, especially at night when it can disrupt your sleep:</p> <ul> <li> <p>use the “night mode” setting on your device or use a blue-light filter app to reduce your exposure to blue light in the evening</p> </li> <li> <p>minimise screen time before bed and create a relaxing bedtime routine to avoid the types of sleep disturbances that can affect the health of your skin</p> </li> <li> <p>hold your phone or device away from your skin to minimise exposure to blue light</p> </li> <li> <p>use sunscreen. Mineral and physical sunscreens containing titanium dioxide and iron oxides offer broad protection, including from blue light.</p> </li> </ul> <h2>In a nutshell</h2> <p>Blue light exposure has been linked with some skin concerns, particularly pigmentation for people with darker skin. However, research is ongoing.</p> <p>While skincare to protect against blue light shows promise, more testing is needed to determine if it works.</p> <p>For now, prioritise good sun protection with a broad-spectrum sunscreen, which not only protects against UV, but also light.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233335/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, Associate Professor of Dermatology, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Felt like a criminal": Mother and disabled son "kicked out" of Pink concert

<p>A distraught mother has taken to social media to recall the moment her and her seven-year-old son, who has Down syndrome, were asked to leave a concert venue. </p> <p>Vanessa Vasey, 48, spent over $1,000 to take her son Jesse to see Pink in London during her UK stadium tour, but when the pair arrived at the venue, things took a turn. </p> <p>Jesse struggled to stay still in his seat and was soon surrounded by "six security guards" who ordered the disabled boy to sit down, otherwise they would have to leave.</p> <p>She said she tried to explain her son’s condition to the guards but they ended up being “escorted from the premises” just as Pink took to the stage.</p> <p>On Facebook, Vasey wrote in detail about what happened, saying her son had been “robbed” of a special experience.</p> <p>“Music is his life and Pink is one of his absolute favourites,” she wrote.</p> <p>“We successfully saw her perform at BST Hyde Park last year and were thrilled to learn of her return again this year.”</p> <p>Vasey said she purchased more expensive “hospitality tickets” allowing people to move between bars and food outlets during the night “so that Jesse wouldn’t be pressured into remaining in one seat all night, as he gets overwhelmed in busy environments and finds it hard to sit still.”</p> <p>“We spent some time in the bar leading up to the main act, and Jesse was having a wonderful time, until about 45 minutes before Pink was due to come on, they suddenly shut all the blinds, obstructing us from seeing anything,” she wrote.</p> <p>“I tried to consult with the hospitality managers over this, and explained Jesse’s needs, but they wouldn’t budge on it. So not wanting Jesse to stare at a blind all night, we attempted to go into the seating zone."</p> <p>“We couldn’t get him to sit in his seat, but he was happy dancing and singing at the front railings, and even interacting with some of the other guests."</p> <p>“Doing no harm to anyone, or obstructing anyone’s view. This seemed OK for about half an hour or so. Then ... just as Pink dropped from the sky in her opening number, we had six security guards come into the zone and ask us to leave or sit in our seats.”</p> <p>Vasey said the security guards were “abrupt, intimidating and unpleasant”, as they "tried to force us to take Jesse to a sensory room which was soundproof, and watch Pink on a screen.” </p> <div> </div> <p>“Something we could do at home, robbing us of the whole experience, as if my son was some sort of inconvenience, and better off shut in a room out of sight.”</p> <p>When Vasey complained to venue staff, she claims that more security guards appeared and they had no choice but to leave. </p> <p>“We were escorted out of the building like criminals and saw no more of the Pink show. Jesse was utterly devastated, and they showed absolutely zero care or understanding."</p> <p>“Shame on you Tottenham Stadium,” she concluded. “My poor boy deserved so much better than this!”</p> <p>After UK media picked up Vasey's story, Tottenham Stadium released a statement explaining their actions. </p> <p>“Following further investigation, we can confirm that Ms Vasey was offered assistance by our Safeguarding and Welfare teams throughout the night to provide Jesse with a comfortable viewing experience, including access to our dedicated Sensory Room,” the statement read.</p> <p>“The offers of assistance were declined by Ms Vasey and the party chose to leave the event.”</p> <p>Vasey was soon set upon by online trolls who condemned her choice to take Jesse to the concert in the first place, to which she issues a lengthy statement about inclusivity and not singling people out for their disabilities. </p> <p>“Why do we take them [to events]? Because, as parents, we have the same dreams and aspirations for our children as any other parent,” she wrote.</p> <p>“We have the same desires to see our children’s faces light up, as any other parent would. Our children are exposed to the same world as other children, and they enjoy the same things."</p> <p>“They have the same likes and desires. The only thing that’s different is their needs, their abilities and their way of accessing their dreams."</p> <p>“Why should these things deny them of fulfilling these dreams and passions? This is meant to be a world of inclusion. So let’s start including!"</p> <p>“That means adapting, understanding, supporting and most importantly; changing the way we deliver these privileges so that they are privileges for all of us, and not just some of us.”</p> <p><em>Image credits: Facebook/Richard Isaac/Shutterstock Editorial </em></p>

Pilot captures once in a lifetime photo of the Northern Lights

Pink's sweet surprise for young fan's birthday

<p>Pink has continued to spread the love during her Australian tour. </p> <p>The <em>So What </em>singer surprised a young fan backstage at her Melbourne show Thursday night, with the sweet moment captured on camera. </p> <p>11-year-old Molly received an unforgettable gift as Pink personally sang <em>Happy Birthday</em> to her and gave her a birthday cake. </p> <p>Chris Hemsworth’s wife, Elsa Pataky filmed and shared the sweet moment on Instagram with the caption: “Girls night to go see Pink in concert. You are amazing.

"Good luck!": Pink stops show as pregnant fan goes into labour

<p>It's not every day that you can say pop icon Pink stopped her show as you were going into labour, but for one Sydney fan this was her reality. </p> <p>The <em>So What </em>singer briefly stopped her show after spotting a pregnant woman getting wheeled out of her concert by a medic on Friday. </p> <p>Wanting to know what all the commotion was about, Pink stopped half way through her performance of <em>Our Song </em>and excitedly tried to find out the baby-to-be's gender, after discovering  that the concertgoer was experiencing contractions. </p> <p>"Is it Alicia or Alex being born?" she asked from the stage, referencing her birth name, Alecia Beth Moore. </p> <p>The singer then playfully said that they shouldn't "be looking" anymore and urged the crowd to give the woman some "privacy."</p> <p> </p> <div class="embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important; width: 573px; max-width: 100%;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7333559856185593090&amp;display_name=tiktok&amp;url=https%3A%2F%2Fwww.tiktok.com%2F%40miss_chantal%2Fvideo%2F7333559856185593090&amp;image=https%3A%2F%2Fp16-sign-sg.tiktokcdn.com%2Fobj%2Ftos-alisg-p-0037%2F22874a6d4d174a149b284ecb5a642be4_1707477473%3Fx-expires%3D1707865200%26x-signature%3DNsu2Nw7zUT%252Bf6ndURt3fjSjaZfg%253D&amp;key=59e3ae3acaa649a5a98672932445e203&amp;type=text%2Fhtml&amp;schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> <p>"Wow, Our Song, that was the one that did it. Wouldn't have called that one! I thought it would've been Get The Party Started or 'Never Not Gonna Dance Again," she said, before congratulating the mum-to-be. </p> <p>"That's exciting. I don't even know what to say. But we have to sing now. Good luck! It's gonna be great! You're gonna do great," she said. </p> <p>A clip of the moment was shared on TikTok, with fans hoping that the mum had a safe delivery.</p> <p>"Baby is like nah I wanna see pink I don’t wanna just hear. Hope mama had a safe delivery 💕💕" one wrote. </p> <p>"Yep or maybe bubba is thinking will this make pink my godmother 😂💕" another added. </p> <p><em>Images: TikTok</em></p> <p> </p>

Bizarre reason Pink has begun to receive "many death threats"

<p>Pop sensation Pink, whose real name is Alecia Beth Moore, recently found herself embroiled in a controversy that led to the cancellation of two tour dates in Tacoma, Washington, and the singer addressing the "many death threats" she received from individuals who mistakenly accused her of showing support for Israel during her shows.</p> <p>The allegations arose amid the ongoing Israeli-Palestinian conflict, and Pink felt compelled to clarify her stance.</p> <p>On social media platform, X (formerly Twitter), Pink shared a statement explaining the misunderstanding. She revealed that some concertgoers had mistaken the Māori Poi flags used in her performances for Israeli flags.</p> <p>Pink emphasised that she was not taking a side in the conflict but rather incorporating these flags as a tribute to the Māori people of New Zealand.</p> <p>She stated, "I do not fly flags in my show in support of anything or anyone except the rainbow flag. That will remain my position. I am a human. I believe in peace. Equality. Love. I am deeply saddened by the state of the world. I pray for all of us."</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">This post will be controversial for some. At this point, breathing is controversial. I am getting many threats because people mistakenly believe I am flying Israeli flags in my show. I am not. I have been using Poi flags since the beginning of this tour. These were used many,…</p> <p>— P!nk (@Pink) <a href="https://twitter.com/Pink/status/1713747866777448930?ref_src=twsrc%5Etfw">October 16, 2023</a></p></blockquote> <p>In the face of this controversy, Pink also addressed the cancellation of two Tacoma, Washington tour dates, initially citing "family medical issues" as the reason. In an Instagram post, she expressed her apologies to ticket holders and stated that Live Nation was working to reschedule these shows. She extended her well wishes, saying, "I am sending nothing but love and health to all."</p> <p>Pink's commitment to her values and her desire to maintain a peaceful and inclusive message in her performances remain steadfast. This controversy came just three weeks after she ejected a concertgoer from her San Antonio show for attempting to protest circumcision.</p> <p>During an acoustic session, the man displayed a sign on his phone reading, "circumcision: cruel and harmful". Pink responded by asking him to remove the sign and humorously quipping, "You spent all this money to come here and do that? I'm gonna have to buy a Birkin bag with that type of money. Get that s--t out of here."</p> <p>Pink is not only known for her incredible musical talent but also for her strong convictions and commitment to social causes. This latest incident further highlights her dedication to promoting peace, equality and love. The singer is set to embark on a tour Down Under next year, with Tones and I joining her for this musical journey. She also recently added two extra shows to her Australian lineup to accommodate her enthusiastic fan base.</p> <p><em>Images: Instagram</em></p>

Do blue-light glasses really work? Can they reduce eye strain or help me sleep?

<p><em><a href="https://theconversation.com/profiles/laura-downie-1469379">Laura Downie</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>Blue-light glasses are said to <a href="https://www.baxterblue.com.au/collections/blue-light-glasses">reduce eye strain</a> when using <a href="https://www.blockbluelight.com.au/collections/computer-glasses">computers</a>, improve your <a href="https://www.ocushield.com/products/anti-blue-light-glasses">sleep</a> and protect your eye health. You can buy them yourself or your optometrist can prescribe them.</p> <p>But <a href="https://mivision.com.au/2019/03/debate-continues-over-blue-blocking-lenses/">do they work</a>? Or could they do you harm?</p> <p>We <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">reviewed</a> the evidence. Here’s what we found.</p> <h2>What are they?</h2> <p>Blue-light glasses, blue light-filtering lenses or blue-blocking lenses are different terms used to describe lenses that reduce the amount of short-wavelength visible (blue) light reaching the eyes.</p> <p>Most of these lenses prescribed by an optometrist decrease blue light transmission by <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">10-25%</a>. Standard (clear) lenses do not filter blue light.</p> <p>A wide variety of lens products are available. A filter can be added to prescription or non-prescription lenses. They are widely marketed and are becoming <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">increasingly popular</a>.</p> <p>There’s often an added cost, which depends on the specific product. So, is the extra expense worth it?</p> <h2>Blue light is all around us</h2> <p>Outdoors, sunlight is the main source of blue light. Indoors, light sources – such as light-emitting diodes (LEDs) and the screens of digital devices – emit varying degrees of blue light.</p> <p>The amount of blue light emitted from artificial light sources is much lower than from the Sun. Nevertheless, artificial light sources are all around us, at home and at work, and we can spend a lot of our time inside.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=3 2262w" alt="Blue light-filtering lenses block some blue light from screens from reaching the eye" /></a><figcaption><span class="caption">Screens emit blue light.

So we conducted a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">systematic review</a> to bring together and evaluate all the relevant studies.</p> <p>We included all randomised controlled trials (clinical studies designed to test the effects of interventions) that evaluated blue light-filtering lenses in adults. We identified 17 eligible trials from six countries, involving a total of 619 adults.</p> <h2>Do they reduce eye strain?</h2> <p>We found no benefit of using blue light-filtering lenses, over standard (clear) lenses, to reduce eye strain with computer use.</p> <p>This conclusion was based on consistent findings from three studies that evaluated effects on eye strain over time periods ranging from two hours to five days.</p> <h2>Do they help you sleep?</h2> <p>Possible effects on sleep were uncertain. Six studies evaluated whether wearing blue-light filtering lenses before bedtime could improve sleep quality, and the findings were mixed.</p> <p>These studies involved people with a diverse range of medical conditions, including insomnia and bipolar disorder. Healthy adults were not included in the studies. So we do not yet know whether these lenses affect sleep quality in the general population.</p> <h2>Do they boost your eye health?</h2> <p>We did not find any clinical evidence to support using blue-light filtering lenses to protect the macula (the region of the retina that controls high-detailed, central vision).</p> <p>None of the studies evaluated this.</p> <h2>Could they do harm? How about causing headaches?</h2> <p>We could not draw clear conclusions on whether there might be harms from wearing blue light-filtering lenses, compared with standard (non blue-light filtering) lenses.</p> <p>Some studies described how study participants had headaches, lowered mood and discomfort from wearing the glasses. However, people using glasses with standard lenses reported similar effects.</p> <h2>What about other benefits or harms?</h2> <p>There are some important general considerations when interpreting our findings.</p> <p>First, most of the studies were for a relatively short period of time, which limited our ability to consider longer-term effects on vision, sleep quality and eye health.</p> <p>Second, the review evaluated effects in adults. We don’t yet know if the effects are different for children.</p> <p>Finally, we could not draw conclusions about the possible effects of blue light-filtering lenses on many vision and eye health measures, including colour vision, as the studies did not evaluate these.</p> <h2>In a nutshell</h2> <p>Overall, based on relatively limited published clinical data, our review does not support using blue-light filtering lenses to reduce eye strain with digital device use. It is unclear whether these lenses affect vision quality or sleep, and no conclusions can be drawn about any potential effects on the health of the retina.</p> <p>High-quality research is needed to answer these questions, as well as whether the effectiveness and safety of these lenses varies in people of different ages and health status.</p> <p>If you have eye strain, or other eye or vision concerns, discuss this with your optometrist. They can perform a thorough examination of your eye health and vision, and discuss any relevant treatment options.<!-- Below is The Conversation's page counter tag.

Fan throws mother’s ashes on stage at Pink concert

<p>Singing sensation Pink was left momentarily speechless after a fan threw a bag of their mother’s ashes on stage mid-performance.</p> <p>The singer was just four songs into her headlining set at the British Summer Time festival in London’s Hyde Park when she grabbed a large package of white powder that had been thrown across the stage.</p> <p>“Is this your mum?” a confused Pink asked.</p> <p>“I don’t know how I feel about this.”</p> <p>Simply stunned, the singer then placed the package down behind the front-of-stage speakers and continued performing the current song, <em>Just Like A Pill</em>.</p> <p>Pink did not speak out about the bizarre situation, but social media users put the concert-goer on blast for the act.</p> <p>“Someone gave their Mothers ashes to Pink. I need yall to have boundaries like girl what?” one fan wrote.</p> <p>“She handled it well cause I’d definitely be mad that someone handed me their mom’s ashes,” another added.</p> <p>“I feel like security at a concert will be like going thru TSA if people don’t stop being WEIRD,” a third wrote.</p> <p>Other online users had more extreme takes, “I would have started snorting their mother on stage,” one person wrote on twitter, while another insisted they would’ve “sprinkled it on the crowd.”</p> <p>This incident follows a string of boundary-breaking events at pop stars’ concerts, with singer Bebe Rexha receiving stitches after a fan threw a phone at her head, and another singer Ava Max having to end her show abruptly after a concert-goer rushed the stage and slapped her in the face.</p> <p>Pink will be returning to Australia for a string of stadium shows in February 2024.</p> <p>While the star hasn’t touched on the matter, there’s a good chance she'd recommend leaving the deceased at home.</p> <p><em>Image credit: TikTok</em></p>

How one brave mum is shedding light on postnatal depression through the healing power of music

<p dir="ltr"><em><strong>Warning: This article contains sensitive content which some readers may find distressing.</strong></em></p> <p dir="ltr">It’s no secret that having a baby changes your life in every way. From sleepless nights and feeding routines, to nappy changes and seemingly endless crying, starting a family is, put simply, a life-altering experience. </p> <p dir="ltr">And while the early days of having a newborn can bring love and chaos in equal parts, for some, the days, weeks and months after giving birth can welcome a whole new set of challenges.</p> <p dir="ltr">While most parents are privy to the “baby blues” and a rough day here and there, those struggling with postnatal depression can often be overlooked. </p> <p dir="ltr">Postnatal depression is common, with one in five mums, and one in 10 dads, experiencing postnatal depression symptoms after their baby is born.</p> <p dir="ltr">For Lija (pronounced Le-ah), postnatal depression completely changed her life. </p> <p dir="ltr">Lija, a music teacher from the Central Coast of New South Wales, welcomed her first child, a beautiful daughter named Harper, into the world at the end of 2017. </p> <p dir="ltr">When Lija discovered she was going to become a mum, she was overcome with fear. </p> <p dir="ltr">Lija spoke exclusively with <em>OverSixty</em> about her journey with postnatal depression, and how her feelings of anxiety began as soon as she fell pregnant. </p> <p dir="ltr">“There was this lie in my head that I could not give birth… That I would die. You feel like you can’t make a way through it and you’re predicting all these complications. [Lija’s friends’ traumatic birth experience] confirmed all these feelings and i just thought ‘Maybe you die from this’.”</p> <p dir="ltr">As soon as Lija and her husband began to celebrate the news of their growing family, she quickly began to “spiral” into self-doubt and depressive episodes. </p> <p dir="ltr">“When I found out I was pregnant, it was a spiral. I didn’t think I was good enough, I was crying so much… I didn’t feel like I could tell anyone because I was so gripped in fear.”</p> <p dir="ltr">“It took me about seven months to accept that I was having a kid.”</p> <p dir="ltr">Over the course of her pregnancy, Lija’s mental health continued to plummet with her feelings of fear and self-doubt, which led her down an even darker path. </p> <p dir="ltr">“The worst part was I was suicidal. There were moments where I wanted to end my life because I just felt like my time was up.”</p> <p dir="ltr">These feelings of helplessness led Lija to reach out to a counsellor, who helped manage her mental health symptoms for the rest of her pregnancy and introduced her to hypnobirthing.</p> <p dir="ltr">Her sessions with a hypnobirthing specialist gave Lija the boost she needed to be in tune with her body, and get her through to Harper’s birth with a sense of confidence. </p> <p dir="ltr">“If I’ve grown a baby, I can give birth to a baby. It was all just focus.”</p> <p dir="ltr">When Harper was born, Lija remembers healthcare professionals warning her husband that her mental health could decline, but she was never spoken to directly.</p> <p dir="ltr">“Apparently nurses were talking to my husband after the birth saying ‘She’s going to be prone to postnatal depression, you need to watch her’, but no one told me I was going to be so lonely.” </p> <p dir="ltr">“I was so focused on the birth going well that I hadn’t thought about what happens after, and I didn’t know what postnatal depression was.”</p> <p dir="ltr">When Lija and her husband brought baby Harper home, as they encountered perfectly common issues around sleep and breastfeeding, Lija thought she had failed as a first-time mum.</p> <p dir="ltr">“I felt like I failed as a mum because I couldn't give Harper everything she needed. And that started all these terrible thoughts and I just started to mentally spiral down again. But I didn’t know for about six months that I had postnatal depression.”</p> <p dir="ltr">During the first few months of Harper’s life, Lija began to find simple day-to-day tasks very difficult. </p> <p dir="ltr">“My poor husband… I was a psycho. It began when I said no one was allowed to come over because I was constantly in my pyjamas and I felt ashamed that my house wasn’t clean.”  </p> <p dir="ltr">Lija shared that as she began to settle into the reality of being a mum, Harper’s needs always came first. </p> <p dir="ltr">“I was just in such a routine. I needed to have my baby follow a good structure, which meant my mental health took a backseat. So I just kept spiralling and spiralling.”</p> <p dir="ltr">As Lija tried to better herself, she quickly found out that comparing yourself to other new parents is a slippery slope that welcomes thoughts of self-doubt. </p> <p dir="ltr">“I tried to go to a mum’s club and they all seemed so perfect. I feel like they weren’t real. It was like Instagram mums. So to try and look good, I was spending all this money to try and keep up appearances.”</p> <p dir="ltr">As Lija’s mental health continued to suffer, she said it wasn’t until a difficult conversation with her husband that she realised she needed professional help. </p> <p dir="ltr">“I wasn’t being the normal me. There was no joy, there was no laughter, and I felt like I failed as a mother and as a wife. So my husband said ‘I’ve booked you in for a therapy session’, and that was the start of it.”</p> <p dir="ltr">“I wanted to be better for Harper. I wanted to be a good mum for her. So I had to start working on myself.”</p> <p dir="ltr">Now, five years on, Lija is reflecting on her experience with postnatal depression in the best way she knows how: through her music. </p> <p dir="ltr">Lija’s debut single <em>Save Me</em> details her journey of becoming a mum and bettering herself, while painting an honest portrait of the first months of motherhood. </p> <p><iframe title="YouTube video player" src="https://www.youtube.com/embed/tmHTlybb-rM" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe></p> <p dir="ltr">After being a musician for most of her life, Lija’s passion took a backseat when she became a mother. </p> <p dir="ltr">“I started to miss my music, because I've done music my whole life. It was so hard to walk past my studio and see the guitar going to waste. I started to miss the other half of me as a musician.”</p> <p dir="ltr">After working on <em>Save Me</em> for several years, Lija believes it is the right time to put her story out there in order to help and inspire other parents struggling with postnatal depression.</p> <p dir="ltr">“It’s okay to be vulnerable. Be real, because you can help others with your honesty.”</p> <p dir="ltr">“It’s also important to remember that babies aren’t going to remember the best outfits they were in, or if they had the best pram. They're going to remember if they were loved or not.”</p> <p dir="ltr">Lija has long been a champion of music and its healing power, which became a saviour in her darkest times through her postnatal depression journey.</p> <p dir="ltr">“I went back to teaching music three months after having Harper. I worked one day a week and these kids and teenagers that were singing to me were actually healing me with their music and their talent.”</p> <p dir="ltr">“Music is something I have always turned to. It has always spoken to me, and I thought if I write a song about my journey, that could heal me too. I thought ‘It’s time to kick fear in the butt and write about life’.”</p> <p dir="ltr">Musical talent is something that runs in the family, with Harper’s singing talents already at “the next level”.</p> <p dir="ltr">“I swear she came out singing! Her ability to hear pitch is insane. In lockdown, she would be singing scales while I was teaching music classes over Zoom. She is just so joyous, and she is like my healing.”</p> <p dir="ltr">Lija’s debut single <em>Save Me</em> is out on now.</p> <p dir="ltr"><strong>Don't go it alone.

How pink became fashion’s colour of controversy: a brief history

<p>From the blush pink of royal mistresses to the hot pink of tabloid party girls, pink has gained a reputation for being a provocative colour for those who dare to wear it.</p> <p>Despite its various shades and the complexities of its cultural significance, it is a colour that is often branded with the same connotations of feminine frivolity and excess – whether girlish and innocent or womanly and erotic. </p> <p>So much so that worshippers at a North London church were ordered to remove pink chairs after an ecclesiastical judge claimed that the choice of colour scheme could <a href="https://www.thetimes.co.uk/article/church-sees-red-over-bright-pink-chairs-3trg9xpgk">“cause puzzlement”</a>.</p> <p>This pink panic invites the question: why is pink so controversial? </p> <p>A brief glimpse at its rather colourful history in the Western world reveals associations that both shape and challenge what pink means.</p> <h2>Pink’s past</h2> <p>According to historian <a href="https://thamesandhudson.com/pink-the-history-of-a-punk-pretty-powerful-colour-9780500022269">Valerie Steele</a>, the birth of pink in modern fashion began in the 18th century. By this period, pink had become the colour of choice among courtly elites of the Western world, including royalty and aristocrats.</p> <p>Developments in dye making and the French court’s penchant for cutting-edge garments provided the perfect pairing to begin pink’s success as an emerging fashion staple.</p> <p>Perhaps the most instrumental influence on pink’s power was Madame de Pompadour – the mistress of King Louis XV. She was often portrayed by the painter François Boucher sporting her signature pink gowns and shoes, most notably in his 1759 piece <a href="https://www.theguardian.com/culture/2001/sep/08/art">Madame de Pompadour</a>.</p> <p>In his 1758 painting, <a href="https://harvardartmuseums.org/collections/object/303561">Madame de Pompadour at Her Toilette</a>, she is shown applying rouge from a box of cosmetics – the blushed cheeks implying female sexuality. For Steele, the colour pink in this period becomes attached to both the frivolity of French high fashion and the eroticising of white femininity.</p> <p>From the 18th century court to the 20th century home, pink gained further traction in the 1950s. As British professor of design history <a href="https://books.google.co.uk/books/about/As_Long_as_It_s_Pink.html?id=By0qAAAAYAAJ">Penny Sparke</a> writes: “Linked with the idea of female childhood, [pink] represented the emphasis on distinctive gendering that underpinned 1950s society, ensuring that women were women and men were men.”</p> <p>Whether <a href="https://www.google.com/url?sa=t&amp;rct=j&amp;q=&amp;esrc=s&amp;source=web&amp;cd=&amp;cad=rja&amp;uact=8&amp;ved=2ahUKEwjvufXu-vb7AhVJi1wKHY_RCrIQFnoECCYQAQ&amp;url=https%3A%2F%2Fwww.lofficielusa.com%2Ffashion%2Fhistory-behind-jackie-kennedy-pink-suit-chanel-jfk&amp;usg=AOvVaw2gvTMarBjpgCPRBDcV2AwN">adorning first ladies</a>, Hollywood stars or housewives, pink in this era represented a traditional femininity grounded in fixed gender roles.</p> <p>Marilyn Monroe’s iconic pink gown in <a href="https://www.imdb.com/title/tt0045810/">Gentleman Prefer Blondes (1953)</a> paired with her <a href="https://www.bloomsbury.com/uk/stars-9781838718374/">typecast “dumb blonde” film roles</a> and her <a href="https://www.huffingtonpost.co.uk/entry/a-visual-history-of-marilyn-monroe-pin-up-icon_n_56ba8d67e4b0c3c5504f5ee4">pin-up past</a> work together to reinforce the star as a sex symbol to be desired by audiences. As film scholar <a href="https://www.routledge.com/Heavenly-Bodies-Film-Stars-and-Society/Dyer/p/book/9780415310277">Richard Dyer</a> argues, Monroe represented the epitome of sex in conversative 1950s American society.</p> <p>On the other end of the scale, the first lady of the United States Mamie Eisenhower – wife of president Dwight D. Eisenhower (1953-1961) – cultivated an image of the ideal housewife through her famous “First Lady Pink” looks.</p> <p>Her stunning <a href="https://www.si.edu/newsdesk/photos/mamie-eisenhowers-inaugural-gown-1953">1953 inaugural outfit</a> was a sparkling pink gown embroidered with more than 2,000 rhinestones. She was well-known for her love of all things pink and transformed the White House with this colourful décor, so much so that the household staff called it a <a href="https://www.nps.gov/museum/exhibits/eise/Mamie/personal_interests/EISE3765_scale4.html">“Pink Palace”</a>.</p> <h2>Punk and protest</h2> <p>Beyond the 1950s, pink moved away from its associations of conformity and took on a new purpose: resistance.</p> <p>Paul Simonon, bassist for English punk band The Clash, <a href="https://www.economist.com/1843/2018/09/20/in-the-pink-the-fashion-history-of-a-divisive-colour">famously said</a> that “pink is the only true rock and roll colour”.</p> <p>We can certainly see this in the way that punk musicians reappropriate the sweet and girlish connotations of pink to create subversive performances.</p> <p>For her <a href="https://www.theguardian.com/arts/pictures/image/0,8543,-10704677171,00.html">1999 performance at Glastonbury</a>, Hole’s Courtney Love – notorious for her raw and raucous vocals – unexpectedly swapped her rebellious grunge girl look for a pink costume of ballet slippers and fairy wings.</p> <p>Pink is also the colour of feminist activism. The 2017 women’s march saw protesters taking to streets in pink “pussy hats”. </p> <p>They were responding to <a href="https://www.nytimes.com/2016/10/08/us/donald-trump-tape-transcript.html">a recording</a> of then president Donald Trump, in which he boasted about <a href="https://www.google.com/url?sa=t&amp;rct=j&amp;q=&amp;esrc=s&amp;source=web&amp;cd=&amp;cad=rja&amp;uact=8&amp;ved=2ahUKEwiO4Z7P-_b7AhVMEsAKHdtLBAgQFnoECAoQAQ&amp;url=https%3A%2F%2Ftheconversation.com%2Ffrom-chaucer-to-trump-sexist-banter-has-been-defended-as-entertainment-for-600-years-84804&amp;usg=AOvVaw0dCQPpZyNUtNJACNJ7CANh">grabbing women “by the pussy”</a>.</p> <p>This explicit connection between pink, female genitalia and activism is a feminist statement that emphasises women’s lack of autonomy over their own bodies in a patriarchal society.</p> <h2>Pink reclaimed</h2> <p>The connotations of pink are not fixed, but malleable. Whether worn by film stars, musicians or celebrities, the colour takes on new meanings through irony and reclamation.</p> <p>The 2001 film <a href="https://www.imdb.com/title/tt0250494/">Legally Blonde</a> subverts the gendered <a href="https://www.routledge.com/Neo-Feminist-Cinema-Girly-Films-Chick-Flicks-and-Consumer-Culture/Radner/p/book/9780415877749">“dumb blonde” stereotypes </a>associated with wearing pink by following the successes of a sorority girl who goes to law school.</p> <p>When Madonna donned her pink Material Girl look, she positioned herself as <a href="https://mcfarlandbooks.com/product/the-performance-identities-of-lady-gaga/">the new Marilyn Monroe</a>: a blonde bombshell for the era of Second Wave Feminism. She reworked Monroe’s tragic stardom into a narrative about female empowerment and survival.</p> <p>On TikTok, the <a href="https://www.refinery29.com/en-gb/2020/12/10217066/tiktok-bimbo-gen-z-trend">#Bimbo trend</a> involves feminine-presenting content creators finding inspiration in the once derogatory “bimbo” label. Their videos <a href="https://www.theguardian.com/commentisfree/2022/mar/23/the-bimbo-is-back-and-as-a-feminist-i-couldnt-be-more-delighted">reclaim the label</a> as a playful aesthetic and a new feminist lifestyle.</p> <p>Despite its longstanding associations with feminine frivolity and excess, pink consistently proves itself to be a transgressive colour. It moves with the times and does not shy away from parodying its own past.</p> <p>If Paris Hilton’s <a href="https://www.vogue.co.uk/fashion/article/paris-hilton-versace-show">surprise runway appearance</a> earlier this year in sparkling pink Versace bridal wear tells us anything, it’s that pink should never be underestimated. It still has the power to shock, fascinate and make a statement.</p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/how-pink-became-fashions-colour-of-controversy-a-brief-history-196535" target="_blank" rel="noopener">The Conversation</a>. </em></p>

The Dark Side of the Moon at 50: how Marx, trauma and compassion all influenced Pink Floyd’s masterpiece

<p><em>Dixi et salvavi animam meam.</em></p> <p>This Latin phrase – I have spoken and saved my soul – sits at the end of Karl Marx’s <a href="https://www.marxists.org/archive/marx/works/1875/gotha/">Critique of the Gotha Programme</a>. </p> <p>Written in 1875, this text imagines a communist society that will come about “after the enslaving of the individual to the division of labour, and thereby also the antithesis between mental and physical labour has vanished”. </p> <p>Only then, Marx argues, “can the narrow horizon of bourgeois right be completely transcended and society inscribe on its banners: from each according to his abilities, to each according to his needs!”</p> <p>Roger Waters – bassist, lyricist and conceptual mastermind behind Pink Floyd’s 1973 album <em>The Dark Side of the Moon</em>, released 50 years ago today – knows Marx’s Critique. Indeed, he quotes it when discussing the record with music journalist John Harris. </p> <p>“Making <em>The Dark Side of the Moon</em>, we were all trying to do as much as we possibly could,” Waters <a href="https://www.goodreads.com/en/book/show/301401">told</a> Harris.</p> <p>"It was a very communal thing. What’s that old Marxist maxim? ‘From each according to his ability, to each according to his need.’ That’s sort of the way the band worked at that point."</p> <p>Assertions about solidarity, cooperation and shared “unity of purpose” – as Waters says – situate <em>Dark Side</em> in the context of Pink Floyd’s <a href="https://faroutmagazine.co.uk/pink-floyd-roger-waters-david-gilmour-feud/">notoriously fractious</a> recording career and helps us understand the album’s enduring appeal.</p> <h2>Shine on you crazy diamond</h2> <p>Pink Floyd formed in London in 1965. Led by the charismatic songwriter, guitarist and lead vocalist Syd Barrett, the group established itself as a leader in the <a href="https://en.wikipedia.org/wiki/UK_underground">London underground music scene</a>. They released their debut album <em>The Piper at the Gates of Dawn</em> in 1967.</p> <p><a href="https://en.wikipedia.org/wiki/Soft_Machine">Soft Machine</a> member Kevin Ayers <a href="https://www.bloomsbury.com/au/pink-floyds-the-piper-at-the-gates-of-dawn-9781441185174/">described</a> <em>The Piper at the Gates of Dawn</em> as “something magical, but it was in Syd Barrett”. </p> <p>Not long after the record’s release, Barrett suffered a catastrophic, LSD-induced breakdown. In response, the band recruited David Gilmour on guitar and recorded a second album, <em>A Saucerful of Secrets</em>, as a five-piece in 1968. Around this time, the increasingly unstable Barrett was unceremoniously ousted by the rest of the band. </p> <p>After Barrett left, says Ayers, “Pink Floyd became something else totally”. </p> <p>There are different versions of Pink Floyd. The recordings released after Barrett left the band in 1968 bear little resemblance to the first. </p> <p><em>Dark Side</em> sounds nothing like the whimsical Piper. But it is obvious the record is in large part preoccupied with the loss of Barrett.</p> <p>This preoccupation comes to the fore in the album’s penultimate track.</p> <p><em><a href="https://www.youtube.com/watch?v=g1OOQP1-wOE&amp;ab_channel=HDPinkFloyd">Brain Damage</a></em>, written and sung by Waters, references Barrett’s adolescence (“Remembering games and daisy chains and laughs”), alludes to his illness (“And if the dam breaks open many years too soon”), and acknowledges his leaving the group (“And if the band you’re in starts playing different tunes; I’ll see you on the dark side of the Moon”). </p> <p>Drummer Nick Mason confirms the group didn’t want to lose Barrett.</p> <p>In his <a href="https://www.goodreads.com/book/show/265734.Inside_Out">autobiography</a>, he writes, "He was our songwriter, singer, guitarist, and – although you might not have known from our less than sympathetic treatment of him – he was our friend."</p> <h2>If the dam breaks open many years too soon</h2> <p>What we hear on <em>The Dark Side of the Moon</em> is a band dealing with trauma. </p> <p>In this sense, Dark Side represents the start of a reckoning with the past – a process that culminated with the band’s next record, 1975’s elegiac <em><a href="https://faroutmagazine.co.uk/wish-you-were-here-pink-floyd-seminal-ode-to-the-tragic-life-of-syd-barrett/">Wish You Were Here</a></em>.</p> <p>Culmination is a useful term when it comes to <em>Dark Side</em> more generally. On this record, all the avant-garde techniques and tendencies the band had toyed with in the post-Barrett period – <a href="https://en.wikipedia.org/wiki/Musique_concr%C3%A8te">musique concrète</a>, sonic manipulation, extended improvisation, analogue tape manipulation – come together to spectacular effect. </p> <p><em><a href="https://www.youtube.com/watch?v=-0kcet4aPpQ">Money</a> –</em> with its anti-capitalist lyrics penned by Waters (“Money, it’s a crime; share it fairly, but don’t take a slice of my pie”), odd time signature, and handmade tape-loops mimicking the sounds of cash tills, bags of coins being dropped from great height and bank notes being torn up – is one of the stranger hit singles in pop music history. </p> <p>Be that as it may, Money and the album from which it is taken, of which <a href="https://www.pinkfloyd.com/tdsotm50/">more than 50 million copies</a> have been sold, continue to resonate with listeners worldwide, five decades on from its initial release.</p> <h2>The enormous risk of being truly banal</h2> <p>“I made a conscious effort when I was writing the lyrics for <em>Dark Side of the Moon</em> to take the enormous risk of being truly banal about a lot of it,” Waters told John Harris, “in order that the ideas should be expressed as simply and plainly as possible.”</p> <p>On this point, <a href="https://www.loudersound.com/news/david-gilmour-says-its-pretty-unlikely-he-and-roger-waters-will-resolve-pink-floyd-feud">if nothing else</a>, David Gilmour agrees. He told Harris, "There was definitely a feeling that the words were going to be very clear and specific. That was a leap forward. Things would mean what they meant. That was a distinct step away from what we had done before."</p> <p>Mortality, insanity, conflict, affluence, poverty and, in another nod to Marx, <a href="https://en.wikipedia.org/wiki/Marx%27s_theory_of_alienation">alienation</a> are some of the themes presented on the record. The need – and this brings us full circle – for compassion, if not outright solidarity, is another. </p> <p>This is an album about the importance of understanding, as Waters <a href="https://www.goodreads.com/en/book/show/301401">insists, "T</a>he potential that human beings have for recognising each other’s humanity and responding to it, with empathy rather than antipathy."</p> <p>Given the sorry state of the world in 2023, about which Roger Waters has many <a href="https://www.bbc.com/news/entertainment-arts-64580688">contentious</a> and <a href="https://www.theguardian.com/music/2023/feb/07/pink-floyd-lyricist-calls-roger-waters-an-antisemite-and-putin-apologist">problematic</a> things to say, I wager Pink Floyd’s masterwork will continue to resonate with listeners for a while yet.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/the-dark-side-of-the-moon-at-50-how-marx-trauma-and-compassion-all-influenced-pink-floyds-masterpiece-198400" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Pink reveals how she teaches her daughter the value of hard work

<p>Pop sensation Pink is teaching her daughter an important lesson on the value of hard work.</p> <p>The singer, who is preparing for her new tour, has revealed her daughter, Willow, 11, is going to work alongside her.</p> <p>Pink spoke on the US morning show <em>Today</em>, saying, "Willow has a job on tour,” adding, “We just had to go over minimum wage and it’s different state to state.”</p> <p>She went on to reveal a cheeky exchange she and her daughter had.</p> <p>“I said it’s about $US22.50 ($A32.80) a show depending how long I go, if I run over. She goes, ‘I’ll take $US20 ($A29.20). It’s easier to do the math.’ I’m like ‘That’s not how you negotiate for yourself.’ I’m like, ‘You’ll take $US25 ($36.47), so it’s easier math.’”</p> <p>Although Pink has an estimated net worth of $200 million USD ($291 million AUD), she believes the value of hard work and knowing your worth should be a priority.</p> <p>Pink is also mum to Jameson, 6, with her husband, Carey Hart, and she teased that her son’s negotiating skills were not quite up to scratch either.</p> <p>“Jameson’s just like, ‘I want a lollipop!’” she joked.</p> <p>The pop sensation’s tour kicks off on June 7 in the UK, starting with her first US show in Cincinnati, Ohio, on July 26.</p> <p>Her 11-year-old will be working alongside her mum for the entire tour and is bound to learn many more important life lessons along the way.</p> <p><em>Image credit: Getty</em></p>

“My home away from home”: Pink’s dream Down Under

<p>Pop superstar Pink has revealed that she’s open to the idea of trading in the United States for a life in Australia. </p> <p>While appearing on <em>60 Minutes</em>, the 43-year-old singer shared that she has had serious thought about becoming an Australian citizen. </p> <p>“Last year I was thinking about applying for citizenship,” she confessed, “I am not even joking.”</p> <p>“You should! You’re practically an Aussie,” <em>60 Minutes</em> reporter Amelia Adams encouraged. </p> <p>“I was like ‘if we’re going somewhere, Carey, we’re going–’ and he’s like ‘yep, that’s where we’re going, if we’re going somewhere’, so, I was kinda looking into it,” Pink explained. </p> <p>The star, who lives in Santa Barbara with her husband, Carey Hart, and their children - Willow, 11, and Jameson, 6 - is no stranger to Australia, boasting thousands of fans and a history of successful touring in the country. </p> <p>Most recently, Pink has announced that her Summer Carnival Tour will hit Australia and New Zealand in February and March 2024, set to span seven cities and their stadiums. She has previously only taken to the stage in arena-sized venues, so 2024 will mark her first Australian stadium tour, an exciting prospect for any musician and their supporters. </p> <p>“Bringing it back to where it all started for me… Australia and New Zealand!” Pink captioned her tour announcement Tweet, “Summer 2024 can’t come soon enough!”</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Bringing it back to where it all started for me… Australia and New Zealand! Summer 2024 can’t come soon enough! 😎 <a href="https://t.co/1dun5H8oYd">https://t.co/1dun5H8oYd</a> <a href="https://t.co/JREWE9GM30">pic.twitter.com/JREWE9GM30</a></p> <p>— P!nk (@Pink) <a href="https://twitter.com/Pink/status/1623398740596760581?ref_src=twsrc%5Etfw">February 8, 2023</a></p></blockquote> <p>Pink has not performed in Australia since 2018, when she was in the country for her Beautiful Trauma tour. It seems that distance really has made the heart grow fonder for the singer. </p> <p>The announcement isn’t the only time in recent years that Pink has demonstrated her love for Australia. In 2020, the singer pledged a donation of $500,000 to fire services on the frontline of the year’s devastating summer bushfires. This was after she had already declared them to be heroes, and thanked them for their service, as well as others all across the globe. </p> <p>In that same year, Pink described Australia to be her “second home”. </p> <p>“I can’t wait to bring the Summer Carnival Tour to my home away from home,” the singer announced last week of her delight at getting to visit once again, “and smile and sing together until our cheeks hurt.”</p> <p>Whether or not Pink and her family decide to make the move, it seems safe to say that Australia will always hold a special place in their hearts.</p> <p><em>Image: Getty</em></p>

"I loved him very much": Pink reveals heartbreaking inspiration behind hit track

<p>Multi award winning singer-songwriter Pink has opened up about the heartache that inspired her 2006 hit song ‘Who Knew’. </p> <p>The 43-year-old was chatting to fellow singer Kelly Clarkson on Kelly’s talk show when she made the tragic admission that ‘Who Knew’ is about the loss of two of her friends to drug overdose. </p> <p>“I lost several friends, unfortunately, to overdose,” she told Kelly, “and the second one was very, very, very close to me, and I loved him very much.” </p> <p>The singer was referring to her dear friend Sekou Harris, who died of a heroin overdose at just 14 years old.</p> <p>In a 2012 interview with <em>Entertainment Weekly</em>, Pink said of the song and its inspiration, “I always wanted to write a song for a friend of mine, Sekou Harris, who overdosed on heroin and died. And I never knew how because I didn’t want to force it and write some cheesy overdose song.”</p> <p>When Kelly mentioned that experiencing so much loss “sucks”, Pink countered that loss is unavoidable and that people “need music for that”. </p> <p>“I need music to help me through my feelings,” she said, “and I can numb down really easy.” </p> <p>She opened up about how the song has evolved over the years, and provided her comfort when faced with the deaths of those close to her heart. </p> <p>"But the thing that I love about the song now, after all these years, is that I never get tired of performing it, and it's taken on so many different meanings over the years,” she admitted, “it was about my grandmother at one point. It was about my dog.</p> <p>"I've lost people, so it's always sort of fresh in my heart." </p> <p>This isn’t the first time that Pink has been honest about her history with drugs. In her 2012 <em>EW </em>interview, the singer confessed that she understood addiction, as she “was a hardcore partier from 12 to 15. I was like a candy raver and I was on all the club drugs. Selling Ecstasy and crystal meth and Special K. I overdosed on Thanksgiving of ’95. And then I never took drugs again, ever.”</p> <p>In the same year, Pink told <em>Shape Magazine </em>that although she wasn’t hospitalised, she got the wake-up call she needed, and turned her attention to her wildly successful music career. </p> <p>Viewers of <em>The Kelly Clarkson Show</em> got a bonus look at that very career after the interview, with Pink and Kelly taking to the stage to perform a stunning duet of Pink’s ‘Who Knew’. </p> <p><em>Image: Getty</em></p> <p> </p>

Caught in the act: supermassive black hole 8.5 billion light years away enjoys violent stellar snack

<p>A supermassive black hole at the centre of a galaxy some 8.5 billion years way has ripped apart a nearby star, producing some of the most luminous jets ever seen.</p> <p>When stars and other objects stray too close to a <a href="https://cosmosmagazine.com/space/how-big-is-a-black-hole-watch-how-it-eats/" target="_blank" rel="noreferrer noopener">supermassive black hole</a> they are destroyed by the black hole’s immense gravity.</p> <p>These occurrences, known as <a href="https://cosmosmagazine.com/space/a-star-is-torn/" target="_blank" rel="noreferrer noopener">tidal-disruption events (TDEs)</a>, result in a <a href="https://cosmosmagazine.com/space/the-sleeping-giant-black-hole-that-awoke-to-destroy-a-star/" target="_blank" rel="noreferrer noopener">circling disk of material</a> that is slowly pulled into the black hole and very occasionally, as in the case of supermassive black hole AT2022cmc, ejecting bright beams of material travelling close to the speed of light.</p> <p>Luminous jets are produced in an estimated 1% of cases and are known as a type of astronomical occurrence known as a transient, because they are short-lived.</p> <p>Bright flashes from the jets were spotted in data from the <a href="https://www.ztf.caltech.edu/" target="_blank" rel="noreferrer noopener">Zwicky Transient Facility (ZTF)</a> in <a href="https://astronomerstelegram.org/?read=15232" target="_blank" rel="noreferrer noopener">February this year</a> using a special new technique which can comb through the equivalent of a million pages of information every night.</p> <p>Due to the rapid results produced by the novel data analysis method, a research team in the US was able to swiftly follow up on the transient event with multiwavelength observations of the system from different observatory facilities.</p> <p>The jets were visible across many wavelengths, from X-rays to radio, and follow-up observations enabled the European Southern Observatory’s <a href="https://www.eso.org/public/australia/teles-instr/paranal-observatory/vlt/" target="_blank" rel="noreferrer noopener">Very Large Telescope</a> to place AT2022cmc at a whopping distance of 8.5 billion light years away, while optical and infrared observation from NASA’s <a href="https://www.nasa.gov/mission_pages/hubble/main/index.html" target="_blank" rel="noreferrer noopener">Hubble telescope</a> were able to precisely pinpoint AT2022cmc’s location.</p> <p>“The last time scientists discovered one of these jets was well over a decade ago,” said Michael Coughlin, an assistant professor of astronomy at the University of Minnesota Twin Cities and co-lead on the paper <a href="https://www.doi.org/10.1038/s41586-022-05465-8" target="_blank" rel="noreferrer noopener">published in <em>Nature</em></a>. “From the data we have, we can estimate that relativistic jets are launched in only 1% of these destructive events, making AT2022cmc an extremely rare occurrence.”</p> <p>Exactly why this behaviour is so rare remains an enigma, however, the research team believe that AT2022cmc’s rapid spin powers the jets, adding to the current understanding of the physics of these behemoth dead stars at the centres of galaxies.</p> <p>This detection – and the method used to discover it – are valuable as a future models for astronomers as they scour the skies for more events. “Scientists can use AT2022cmc as a model for what to look for and find more disruptive events from distant black holes,” says lead author Igor Andreoni, from the Department of Astronomy at UMD and NASA Goddard Space Flight Centre.</p> <p>This includes using ground-based optical surveys, as opposed to gamma-ray observatories in space – how previous jets were primarily discovered.</p> <p>“Our new search technique helps us to quickly identify rare cosmic events in the ZTF survey data,” says Andreoni.</p> <p>“And since ZTF and upcoming larger surveys such as <a href="https://www.lsst.org/" target="_blank" rel="noreferrer noopener">Vera Rubin’s Large Synoptic Survey Telescope</a> scan the sky so frequently, we can now expect to uncover a wealth of rare, or previously undiscovered cosmic events and study them in detail. More than ever, big data mining is an important tool to advance our knowledge of the universe”.</p> <p><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=226753&amp;title=Caught+in+the+act%3A+supermassive+black+hole+8.5+billion+light+years+away+enjoys+violent+stellar+snack" width="1" height="1" data-spai-target="src" data-spai-orig="" data-spai-exclude="nocdn" /></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/science/supermassive-black-hole-stellar-snack/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Clare Kenyon. </em></p> <p><em>Image: Getty Images</em></p> </div>
