Readers response: What exercises or activities do you enjoy that help you stay mobile?

It's no secret that we start to physically show down as we age, but keeping active and mobile can keep us going. We asked our readers what exercised they do to keep mobile in retirement years, and the response was overwhelming. Here's what they said. Karen Ambrose - I’ve been a dance teacher since 1982 and am still teaching. Dancing is my happy place! Rosemary Andrews - Dragon Boat Paddling. I started when I was 59. Still going 14 years on. Love it!! Anne Gray - Pilates, Yoga, Zumba. Sue Ryan - Boxing, HIIT, Body Attack, Pilates, Aqua, Pump and running. I’m 72. Wendy Oliver - Chair based exercises. Anne Moulynox - Pickleball at least twice a week. I took up ballet at 70 but gave it up as it was far too sedate, so took up Pickleball at 73. Sally O'Neill - Volunteering makes me get up and meet other people. Robyn Harrison - Swim a kilometre twice a week and two long walks on the beach each week. Suzanne Bluett - Nothing better than walking. Lorraine Clarbull - Tai Chi. Image credits: Shutterstock

Do mobile phones cause brain cancer? Science makes definitive call

The question of whether mobile phones - specifically the electromagnetic radiation or radio waves emitted by these devices - cause cancer has been debated and researched for a long time, and now scientists have made a definitive call. A new comprehensive review commissioned by the World Health Organization has found that mobile phones are NOT linked to brain and head cancers. The systematic review, led by the Australian Radiation Protection and Nuclear Safety Agency (Arpansa), examined over 5,000 studies, which included 63 observational studies on humans published between 1994 and 2022 and is "the most comprehensive review to date" according to review lead author, associate prof Ken Karipidis. “We concluded the evidence does not show a link between mobile phones and brain cancer or other head and neck cancers," he said. The review, which was published on Wednesday, focused on cancers of the nervous system, salivary gland and brain tumours. They found no overall association between mobile phone use and cancer, even if people have used it for a long time (over 10 years) or spend a lot of time on their phones. “I’m quite confident with our conclusion. And what makes us quite confident is … even though mobile phone use has skyrocketed, brain tumour rates have remained stable,” Karipidis continued. Despite emitting electromagnetic radiation, also known as radio waves, the exposure is relatively low. Karipidis said people hear the word radiation and assume it is similar to nuclear radiation, “and because we use a mobile phone close to the head when we’re making calls, there is a lot of concern.” He clarified that “radiation is basically energy that travels from one point to another. There are many different types, for example, ultraviolet radiation from the sun." “We’re always exposed to low-level radio waves in the everyday environment.” While exposure from mobile phones is still low, it is much higher than exposure from any other wireless technology sources since they are used close to the head, Karipidis said. The association between mobile phones and cancers came about from early studies comparing differences between those with and without brain tumours and asking about their exposure history. According to Karipidis, who is also the vice-chair of the International Commission on Non-Ionizing Radiation Protection, the results from these kind of studies tend to be biased, as the group with the tumour tend to overreport their exposure. Based on these early studies WHO’s International Agency for Research on Cancer (IARC) designated radio-frequency fields like those from mobile phones as a possible cancer risk, but Karipidis said "this classification doesn’t mean all that much”. This is because the IARC has different classifications of cancer risk, with some substances classified as a “definite” carcinogen (such as smoking), and others as “probable” or “possible” carcinogens. Tim Driscoll, a professor at the University of Sydney and chair of the Australian Cancer Council’s occupational and environmental cancers committee, also backed the systematic review. “I think people should feel reassured by this study … but it’s worthwhile just remembering that the studies aren’t perfect, but the weight of evidence certainly is that mobile phones should be considered safe to use in terms of any concerns about increased risk of cancer,” Driscoll said.

The captivating winners of the Mobile Photography Awards

It turns out your smartphone camera can do much more than capture pictures of your pets, family holidays and fancy meals. These budding photographers have pushed the limits of their smartphone camera and emerged victorious in the first <a href="https://www.britishphotographyawards.org/2024-mobile-photography-awards/gallery" target="_blank" rel="noopener">Mobile Photography Awards</a>, launched this year by the British Photography Awards (BPA), in partnership with Samsung. Entrants submitted their snaps under categories including Portrait, Landscape, Night Scenes, Food & Drink, Pets and Zoom In, creating some of the most breath-taking pics that look as though they have been taken with a professional camera. BPA Awards Director & Photographer, Hugo Donnithorne-Tait, said, "As photography continues to develop as a medium, it is clear that the way people take and enjoy photos is changing too.' "More and more photographs today are being captured only because people have a top camera in their pocket when they need it. This means so many more of life’s moments are being documented." This year's winning photos feature a father and son sleeping side by side, a hiker atop the Scottish Highlands, the bustling London streets from above and below, a furry friend at bath time, and a few hungry seagulls.

How to avoid mobile phone bill horror stories when travelling

"I'm sorry, calls to this number are not allowed, please try again later". This. Again. At 1am standing outside what I thought was our Galway Airbnb, but instead was a popular alley for Irish revellers to relieve themselves. Brilliant. After begging a convenience store manager, borrowing a phone and stealing some local wi-fi, we made it to bed before 3am (one-star rating for the Airbnb host, naturally). Such was the power of the phone company when you're on holiday, I still got pinged far-too-high amounts for calls and data used to attempt a check-in at the Irish abode. A reader recently contacted me wanting to avoid such a conundrum by asking for the best SIM cards available in Europe. Thankfully, EU law has recently shielded travellers from harsh cross-border roaming charges by ruling that providers cannot charge excessively for access to rival networks in fellow EU nations. You'll see the kiosks hawking pre-paid SIM packages at many major airports. If you want the dependability a SIM provides, assess your needs and shop around. Better yet, get to know your smartphone better and use the whole range of mobile apps that will soon make international call and text roaming redundant. Organising hotels, taxis, tours, dinner reservations as well as calling home and making your friends and colleagues jealous with holiday snaps can all be done with a wi-fi connections, which are readily available and far cheaper (if not free). Avoid phone bill shock when you're away <ul> <li>Contact your mobile phone company rep about your destination and length of stay to see what add-ons and spending caps may be best.</li> <li>Only purchase local SIMs if you're in the country more than a week, have an unplanned itinerary or will have no free wi-fi at your accommodation.</li> <li>If you're on a per-day bundle, choose a few days to be on-the-grid and turn off your mobile data on other days.</li> <li>Go wi-fi only, in North American, Asian and European cities it's readily available.</li> <li>Embrace apps like Uber, Gett, WhatsApp, OpenTable and TripAdvisor to book taxis, call home and book restaurants and tours using hotel wi-fi and thus limiting calls.</li> </ul> Image credit: Shutterstock Written by Josh Martin.

Tips for safe mobile banking

As we increasingly turn to our mobile devices for online transactions, it’s crucial to keep security in mind. We’ve all misplaced our mobile phone at some stage and the last thing you want is for some random stranger to get direct access to your bank accounts and other personal details. 1. Use a strong password – This goes without saying.While it might not be as critical with your library pass, someone who cracks or guesses your online banking password can drain your account dry. If you memorise just one strong password, make it your online banking password. 2. Never store passwords on your smartphone – Many people still try to hide passwords or PIN numbers within the body of text or phone numbers. However, despite how cleverly you may think you've concealed them, criminals know what to look for and where. It's always best to commit these security details to memory and not record them anywhere. This includes not ticking "save password" on website and applications that offer to remember your login details. Also make sure you limit other personal information. Criminals are interested in more than just your internet banking details. Any kind of personal information can be used to steal your identity, which criminals can then use to apply for credit cards, personal loans, even mortgages. 3. Use a password manager – Okay, in the real world you probably have more than one online financial account. Rather than strain your brain memorising hard-to-crack passwords for each of them, look at enlisting the help of a password manager. There are plenty of apps available and the best ones not only store your passwords securely but also help you work through your collection of passwords and replace weak ones and duplicates. 4. Activate smartphone security settings and password protection – All smartphones have built-in security features such as auto-locking and password protection. While it may seem like a bit of an inconvenience at times, these physical security measures are your first line of defense in keeping your smartphone and your personal details safe. You can also install smartphone security software as well as remote data wiping software if you lose your phone or it gets stolen. 5. Connect through your data plan – If you're banking online on a mobile device, you have a degree of in-built protection available when you turn off wi-fi tethering and bluetooth and connect using your mobile data plan. It's a lot harder for criminals to sniff your mobile data stream than to snag passwords from network traffic. If you’re on wi-fi only use reputable hot spots that are password protected. If you connect to a shared wi-fi hotspot you are completely dependent on the security of the host network. 6. Don't be tempted to jailbreak your smartphone – If you crack the manufacturer's security on your smartphone, you not only make your warranty invalid but you make it much more vulnerable to attacks by cybercriminals. 7. Clear your phone when you replace it – If you sell or discard your smartphone, it's crucial you delete all personal information first. This includes SMS messages, emails, photographs, contact details and internet links. Image credit: Shutterstock

What the “father of the cell phone” wants you to know

The inventor of the mobile phone has shared his candid opinion about the obsession with smart devices. Martin Cooper, an American engineer dubbed the “father of the cell phone”, invented the very first mobile phone 50 years ago in 1973. Back then, the weighty block of wires and circuits were only used to make calls, a far cry from having the world at your fingertips with smartphones today. Cooper believes that despite all the good that can come from modern technology, the world has become a little obsessed with smart devices. “I am devastated when I see somebody crossing the street and looking at their cell phone. They are out of their minds,” the 94-year-old told AFP from his office in Del Mar, California. “But after a few people get run over by cars, they’ll figure it out,” he joked. Mr Cooper also indulges in the latest gadgets, as he wears an Apple Watch and uses a top-end iPhone, flicking intuitively between his email, photos, YouTube and the controls for his hearing aid. Despite keeping up with all the latest apps, updates and upgrades, he confessed that sometimes it can all seem a little overwhelming. “I will never, ever understand how to use the cell phone the way my grandchildren and great grandchildren do,” he said. “Each generation is going to be smarter … they will learn how to use the cell phone more effectively,” he said. “Humans sooner or later figure it out.” Image credits: Getty Images

5 tech mistakes not to make while travelling

In the hustle and bustle of preparing for a holiday away we sometimes forget about the small little things. We’re sure you’ve checked off all those big things you needed to do before you jet off but have you considered these simple tech mistakes people often made? We’ve rounded up the top five you’ll want to avoid to ensure your trip is easier and more enjoyable. Not backing anything up You might only be away for a week and it’s just a few hours away so it’s unlikely anything will happen, right? But what if the unexpected does happen and you lose your photos from your phone? What if your tablet gets stolen or lost? What if the memory card goes bust? Back up your phone, tablet and digital camera before you go away and if you’re holidaying for a while, it’s worthwhile to bring a USB stick to periodically back-up. Using your cell data For those going overseas, roaming rates can cost an arm and a leg. Either check if your mobile company has a reasonable international package or switch off the cellular data so your phone won’t use it. Instead limit yourself to wi-fi – most countries have public wi-fi hotspots and most accommodation usually has internet. Remember not to do anything personal on an unsecure wi-fi connection. Making calls instead of using Skype Rather than paying for international calls and texts, Skype will let you stay in touch with friends and family for free. Just make sure you’re connected to wi-fi so you’re not paying for cellular data. Stowing electronics in your check-in luggage You might be tempted to throw some of your electronics in your big luggage, after all you’re not going to be using them on the plane. But remember your check-in bag has to survive manhandling and an unpredictable luggage belt and we’ve all heard stories of items mysteriously disappearing from bags. Keep your expensive electronic with you on your carry-on. Not keeping devices close When you’ve settled into a hotel room, it’s easy to forget they’re not very secure. Think of all the people who have access to your room when you’re not in it. Even leaving valuables behind the desk can bring with it certain risks depending on the establishment you’re staying at. The best advice is to keep your electronics on you at all times. Image credits: Getty Images

Could mobile phones revolutionise chronic wound treatment?

Australian researchers are developing a contactless, thermal imaging system that uses artificial intelligence to help nurses determine the best way to treat leg ulcers without waiting to see if the wound is going to heal properly. It’s estimated that 450,000 thousand Australians currently live with a chronic wound. Being able to predict early on which wounds will become chronic could improve outcomes by enabling nurses to start specialised therapy as soon as possible. But current techniques rely on physically monitoring the wound area over several weeks. New research from RMIT in Melbourne paired thermal imaging with AI. The software was able to accurately identify unhealing ulcers 78% of the time, and healing ulcers 60% of the time, according to the new study <a href="https://www.nature.com/articles/s41598-022-20835-y" target="_blank" rel="noreferrer noopener">published</a> in Scientific Reports. “Our new work that identifies chronic leg wounds during the first visit is a world-first achievement,” says lead researcher Professor Dinesh Kumar, from RMIT’s School of Engineering. “This means specialised treatment for slow-healing leg ulcers can begin up to four weeks earlier than the current gold standard.” How do you normally assess wound healing? The work builds on <a href="https://www.nature.com/articles/s41598-021-92828-2.epdf?sharing_token=7SIEmbOksKOou2TGQ5qPWdRgN0jAjWel9jnR3ZoTv0NntGTf8gfSMhoDjLAz58SefUeGL0aP2A-0mDVnZaiZTcBjNNpA4cvP9FgK6-aoPzyk4oQ0OSbPh83HNS_AwGDQVMg43K4WmG60QDoQohtsdkaRv70YSxfPg4Dn0qa_CUs%3D" target="_blank" rel="noreferrer noopener">previous research</a> by the same team, which found that this method could be used to predict wound healing by week 3 after initial assessment. But they wanted to know whether healing could be predicted from the first wound assessment only, reducing any delay in treatment. If a wound is healing normally it’s area would reduce by 50% within four weeks, but more than 20% of ulcers don’t heal in this expected trajectory and may need specialist interventions. Venous leg ulcers (VLUs) are the <a href="https://treasury.gov.au/sites/default/files/2022-03/258735_wounds_australia.pdf" target="_blank" rel="noreferrer noopener">most common</a> chronic wound seen in Australia and currently, the gold standard for predicting their healing– conventional digital planimetry – requires physical contact. Regular wound photography is also less accurate because there can be variations between images due to lighting, image quality, and differences in camera angle. But a non-contact method like thermal imaging could overcome this. The thermal profile of wounds changes over the healing trajectory, with higher temperatures signalling potential inflammation or infection and lower temperatures indicating a slower healing rate due to decreased oxygen in the region. So, taking thermal images of wounds can provide important information for predicting how they will heal. What did they do? The study collected VLU data from 56 older participants collected over 12 weeks, including thermal images of their wounds at initial assessment and information on their status at the 12th week follow-up. “Our innovation is not sensitive to changes in ambient temperature and light, so it is effective for nurses to use during their regular visits to people’s homes,” says co-author Dr Quoc Cuong Ngo, from RMIT’s School of Engineering. “It is also effective in tropical environments, not just here in Melbourne.” “Clinical care is provided in many different locations, including specialist clinics, general practices and in people’s homes,” says co-author Dr Rajna Ogrin, a Senior Research Fellow at Bolton Clarke Research Institute. “This method provides a quick, objective, non-invasive way to determine the wound-healing potential of chronic leg wounds that can be used by healthcare providers, irrespective of the setting.” So, what’s next? There are a few limitations to this study. First, the number of healed wounds in the dataset was relatively small compared to unhealed wounds, and the study only investigated older people. The authors recommend that “future research should focus on improving the predictive accuracy and customising this method to incorporate this assessment into clinical practice on a wider pool of participants and in a variety of settings.” Kumar says that they are hoping to adapt the method for use with mobile phones. “With the funding we have received from the Medical Research Future Fund, we are now working towards that,” he says. “We are keen to work with prospective partners with different expertise to help us achieve this goal within the next few years.” <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=222978&title=Could+mobile+phones+revolutionise+chronic+wound+treatment%3F" width="1" height="1" /> <div id="contributors"> <a href="https://cosmosmagazine.com/health/revolutionise-chronic-wounds-treatment/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Imma Perfetto.

Mobile phone hoarding: e-waste not good news for the environment

What happened to your previous mobile phone after you upgraded or replaced it? Did it go in a drawer? A box in the garage, perhaps? Today marks International E Waste Day, with this year’s slogan, “Recycle it all, no matter how small!”, specifically targeting small devices with a high recycling value that are often hoarded for years before they become waste. It’s a timely reminder, as results from surveys conducted across Europe suggest that the roughly 5.3 billion mobiles and smartphones dropping out of use this year would reach a height of around 50,000 km if stacked flat and on top of each other. That’s well-and-truly over the average orbiting height of the International Space Station and about an eighth of the distance to the moon. “In 2022 alone, small EEE (Electrical and Electronic Equipment) items such as cell phones, electric toothbrushes, toasters and cameras produced worldwide will weigh an estimated total of 24.5 million tonnes – four times the weight of the Great Pyramid of Giza”, says Magdalena Charytanowicz of the WEEE (Waste Electrical and Electronic Equipment) Forum, responsible for organising <a href="https://www.genevaenvironmentnetwork.org/events/international-e-waste-day-2022/" target="_blank" rel="noreferrer noopener">International E Waste Day</a>. “And these small items make up a significant proportion of the 8% of all e-waste thrown into trash bins and eventually landfilled or incinerated.” With their valuable components of <a href="https://cosmosmagazine.com/technology/critical-minerals-mining-australia/" target="_blank" rel="noreferrer noopener">gold, copper, silver, palladium and other materials</a>, mobile phones ranked fourth amongst small Electrical and Electronic Equipment (EEE) hoarded or unrecoverably discarded – that is put in draws, cupboards or garages – rather than repaired or recycled – or sent to landfill or for incineration. The surveys ran for four months from June 2022 and covered 8,775 households across Portugal, Netherlands, Italy, Romani, Slovenia and the UK and asked participants about common items such as phones, tablets, laptops, electric tools, hair dryers, toasters and other appliances. The top five hoarded small EEE products were (in order): small electronics and accessories (e.g., headphones, remotes), small equipment (e.g., clocks, irons), small IT equipment (e.g., hard drives, routers, keyboards, mice), mobile and smartphones, small food preparation appliances (e.g., toasters, grills). Italy hoarded the highest number of small EEE products, while Lebanon hoarded the least. You might recognise some of the reasons given, which included potential future use, plans to sell or give away, sentimental value, future value, use in a secondary residence or contains sensitive data. Others were also unsure how to dispose of the item or felt there was no incentive to recycle it, and some argued that they’d forgotten, didn’t have time or that the item didn’t take up very much space. This is a shame because such items, despite being small, pack a big punch in recyclability. <div class="newsletter-box"> <div id="wpcf7-f6-p218602-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> </div> </div> “We focussed this year on small e-waste items because it is very easy for them to accumulate unused and unnoticed in households, or to be tossed into the ordinary garbage bin”, says Pascal Leroy, Director General of the WEEE Forum, who have organised International E Waste Day. “People tend not to realise that all these seemingly insignificant items have a lot of value, and together at a global level represent massive volumes.” “These devices offer many important resources that can be used in the production of new electronic devices or other equipment, such as wind turbines, electric car batteries or solar panels – all crucial for the green, digital transition to low-carbon societies,” says Charytanowicz. <h4>What can be done about e-waste?</h4> At the governmental level, there are a number of initiatives including legislation that are coming into effect or being tightened up in order to address this increasing problem. “The continuing growth in the production, consumption and disposal of electronic devices has huge environmental and climate impacts,” says Virginijus Sinkevičius, European Commissioner for the Environment, Oceans and Fisheries. “The European Commission is addressing those with proposals and measures throughout the whole product life-cycle, starting from design until collection and proper treatment when electronics become waste.” “Moreover, preventing waste and recovering important raw materials from e-waste is crucial to avoid putting more strain on the world’s resources. Only by establishing a <a href="https://cosmosmagazine.com/technology/can-a-circular-economy-eliminate-e-waste/" target="_blank" rel="noopener">circular economy</a> for electronics, the EU will continue to lead in the efforts to urgently address the fast-growing problem of e-waste.” There is also a role for more education and communication. Launched today by UNITAR, the UN Institute for Training and Research (UNITAR), is the first self-paced e-waste<a href="https://www.uncclearn.org" target="_blank" rel="noopener"> online training course</a> open to anyone. A UNITAR certificate is available upon graduation of the roughly 1.5-hour course which aims to use scientific findings in a practical way for international training and capacity building,” says Nikhil Seth, UNITAR’s Executive Director. Finally, The WEEE Forum has been actively involved in collecting, de-polluting, recycling or preparing for re-use more than 30 million tonnes of WEEE and has also run communication campaigns for almost twenty years. “Providing collection boxes in supermarkets, pick up of small broken appliances upon delivery of new ones and offering PO Boxes to return small e-waste are just some of the initiatives introduced to encourage the return of these items,” says WEEE’s Leroy. At the personal level, all you have to do is quite your hoarding habits and recycle, instead! <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=218602&title=Mobile+phone+hoarding%3A+e-waste+not+good+news+for+the+environment" width="1" height="1" /> <div id="contributors"> <a href="https://cosmosmagazine.com/earth/e-waste-mobile-phone-bad-news-environment/" target="_blank" rel="noopener">This article</a> was originally published on <a href="https://cosmosmagazine.com" target="_blank" rel="noopener">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/clare-kenyon" target="_blank" rel="noopener">Clare Kenyon</a>.

"This is shocking": Police slammed over sneaky trap

A New Zealand man has clashed with police after he accused an officer of posing as a window washer to catch drivers using their mobile phones. While he was stopped at a traffic light in Manurewa, South Auckland, the man began filming after noticing an undercover cop in a hoodie standing nearby. "He's the cop who gave me the ticket!" he can be heard telling a friend sitting in the car with him. "This is bad, man. He's pretending to be a window washer!" The passenger then gets out of the car and makes his way toward the officer to “let the public know” what was happening. "Alright guys so we've got police here hiding, pretending to be window washers," he says while standing next to the police officer. "So what they do is they stand here and they dress up in hoodies with a window washer thing and they're looking and trying to get people tickets for fines, maybe phones, seatbelts." Within moments, several other officers approach the man. One officer confirms that the “window washer” was an undercover cop, and when the man questions whether the tactic was “saving lives”, an officer says it was. The man is then told by police that he could film but has to do it from the opposite side of the road so that the undercover operation isn’t interfered with. <blockquote class="twitter-tweet"> 😂😂😂 wish one of your cousins is the undercover cop lmao? <a href="https://t.co/5QWvlg2hYy">pic.twitter.com/5QWvlg2hYy</a> — Danny (@disndatnz) <a href="https://twitter.com/disndatnz/status/1577420707008417816?ref_src=twsrc%5Etfw">October 4, 2022</a></blockquote> The hoodie-wearing officer is then encouraged to return to his spot by the side of the road. The clip has since been shared on TikTok and by Today FM, with morning talk show host Duncan Garner speaking to the man’s friend, Neil, who was in the car during the incident. “I've driven up and down the country all the time and I’ve never seen any sort of act like this anywhere apart from there," Neil said. "And the fact that he put on clothes to sort of fit into that area is really quite rude." Stuff reported that NZ Police Inspector Tony Wakelin said the impersonation was inappropriate and that the operation would cease. Meanwhile, social media users have been slamming the police for their “sneaky ways”. "You cannot tell me this isn’t insanely deceptive," one commented. "This is shocking," another shared. "Isn't this entrapment?" a third said. Others defended the operation, saying that the police were just trying to prevent people from doing the wrong thing. "Lord. Get off your phone while you're driving. End of story," one wrote. "No this is good, I have been rear-ended by someone texting and driving," another added. "They are trying to prevent crime and save lives but at the same time they are distracting drivers which can cause accidents," one person shared on Reddit. “So it’s not a good method".

Here’s the real reason to turn on aeroplane mode when you fly

We all know the routine by heart: “Please ensure your seats are in the upright position, tray tables stowed, window shades are up, laptops are stored in the overhead bins and electronic devices are set to flight mode”. Now, the first four are reasonable, right? Window shades need to be up so we can see if there’s an emergency, such as fire. Tray tables need to be stowed and seats upright so we can get out of the row quickly. Laptops can become projectiles in an emergency, as the seat back pockets are not strong enough to contain them. And mobile phones need to be set to flight mode so they can’t cause an emergency for the aeroplane, right? Well, it depends whom you ask. <h2>Technology has advanced a great deal</h2> Aviation navigation and communication relies on radio services, which have been coordinated to minimise interference <a href="https://ntrs.nasa.gov/api/citations/20050232846/downloads/20050232846.pdf">since the 1920s</a>. The digital technology currently in use is much more advanced than some of the older analogue technologies we used even 60 years ago. <a href="https://www.sciencedirect.com/science/article/pii/S2352146521008851">Research has shown</a>personal electronic devices can emit a signal within the same frequency band as the aircraft’s communications and navigation systems, creating what is known as electromagnetic interference. But in 1992, <a href="https://www.livescience.com/5947-real-reason-cell-phone-banned-airlines.html">the US Federal Aviation Authority</a> and Boeing, <a href="https://www.boeing.com/commercial/aeromagazine/aero_10/interfere_textonly.html">in an independent study</a>, investigated the use of electronic devices on aircraft interference and found no issues with computers or other personal electronic devices during non-critical phases of flight. (Take-offs and landings are considered the critical phases.) The US Federal Communications Commission also began to create <a href="https://www.livescience.com/5947-real-reason-cell-phone-banned-airlines.html">reserved frequency bandwidths</a> for different uses – such as mobile phones and aircraft navigation and communications – so they do not interfere with one another. Governments around the globe developed the same <a href="https://ntrs.nasa.gov/api/citations/20050232846/downloads/20050232846.pdf">strategies and policies to prevent interference</a> problems with aviation. In the EU, electronic devices have been <a href="https://www.easa.europa.eu/en/newsroom-and-events/news/easa-allows-electronic-devices-remain-and-connected-throughout-flight">allowed to stay on since 2014</a>. <h2>2.2 billion passengers</h2> Why then, with these global standards in place, has the aviation industry continued to ban the use of mobile phones? One of the problems lies with something you may not expect – ground interference. Wireless networks are connected by <a href="https://www.livescience.com/5947-real-reason-cell-phone-banned-airlines.html">a series of towers</a>; the networks could become overloaded if passengers flying over these ground networks are all using their phones. <a href="https://www.statista.com/statistics/564717/airline-industry-passenger-traffic-globally/">The number of passengers that flew in 2021</a> was over 2.2 billion, and that’s half of what the 2019 passenger numbers were. The wireless companies might have a point here. Of course, when it comes to mobile networks, the biggest change in recent years is the move to a new standard. Current 5G wireless networks – desirable for their higher speed data transfer – have caused concern for many within the aviation industry. Radio frequency bandwidth is limited, yet we are still trying to add more new devices to it. The aviation industry points out that the <a href="https://www.sciencedirect.com/science/article/pii/S2352146521008851">5G wireless network bandwidth spectrum</a> is remarkably close to the reserved aviation bandwidth spectrum, which may cause <a href="https://www.newscientist.com/article/2304975-will-5g-mobile-networks-in-the-us-really-interfere-with-aircraft/">interference with navigation systems near airports</a>that assist with landing the aircraft. Airport operators <a href="https://www.itnews.com.au/news/australian-airports-fret-over-5g-interference-582222">in Australia</a> and <a href="https://www.faa.gov/5g">the US</a> have voiced aviation safety concerns linked to 5G rollout, however it appears to have rolled out without such problems <a href="https://edition.cnn.com/2022/01/19/business/5g-aviation-safety-europe/index.html">in the European Union</a>. Either way, it is prudent to limit mobile phone use on planes while issues around 5G are sorted out. <h2>Ultimately, we can’t forget air rage</h2> Most airlines now provide customers with Wi-Fi services that are either pay-as-you-go or free. With new Wi-Fi technologies, passengers could theoretically use their mobile phones to <a href="https://ieeexplore.ieee.org/abstract/document/8010762">make video calls with friends</a> or clients in-flight. On a recent flight, I spoke with a cabin attendant and asked her opinion on phone use during flights. It would be an inconvenience for cabin crew to wait for passengers to finish their call to ask them if they would like any drinks or something to eat, she stated. On an airliner with 200+ passengers, in-flight service would take longer to complete if everyone was making phone calls. For me, the problem with in-flight use of phones is more about the social experience of having 200+ people on a plane, and all potentially talking at once. In a time when disruptive passenger behaviour, including “air rage”, <a href="http://www.jairm.org/index.php/jairm/article/view/156">is increasingly frequent</a>, phone use in flight might be another trigger that changes the whole flight experience. Disruptive behaviours take on various forms, from noncompliance to safety requirements such as not wearing seat belts, verbal altercations with fellow passengers and cabin crew, to physical altercations with passengers and cabin crews – typically identified as air rage. In conclusion – in-flight use of phones does not currently impair the aircraft’s ability to operate. But cabin crews may prefer not to be delayed in providing in-flight service to all of the passengers – it’s a lot of people to serve. However, 5G technology is encroaching on the radio bandwidth of aircraft navigation systems; we’ll need more research <a href="https://theconversation.com/how-5g-puts-airplanes-at-risk-an-electrical-engineer-explains-175306">to answer the 5G question</a> regarding interference with aircraft navigation during landings. Remember that when we are discussing the two most critical phases of flight, take-offs are optional – but landings are mandatory.

Travel Tips

Can your mobile phone get a virus?

With nearly <a href="https://www.bankmycell.com/blog/how-many-phones-are-in-the-world" target="_blank" rel="noopener">84%</a> of the world’s population now owning a smartphone, and our dependence on them growing all the time, these devices have become an attractive avenue for scammers. Last year, cyber security company Kaspersky detected nearly <a href="https://securelist.com/mobile-malware-evolution-2021/105876/" target="_blank" rel="noopener">3.5 million</a> malicious attacks on mobile phone users. The spam messages we get on our phones via text message or email will often contain links to viruses, which are a type of malicious software (malware). There’s a decent chance that at some point you’ve installed <a href="https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=6138859" target="_blank" rel="noopener">malware</a> that infected your phone and worked (without you noticing) in the background. According to a global report commissioned by private company Zimperium, more than <a href="https://www.zimperium.com/global-mobile-threat-report/" target="_blank" rel="noopener">one-fifth</a> of mobile devices have encountered malware. And four in ten mobiles worldwide are <a href="https://blog.checkpoint.com/2020/08/06/achilles-small-chip-big-peril/" target="_blank" rel="noopener">vulnerable</a> to cyber attacks. But how do you know if your phone has been targeted? And what can you do? How does a phone get infected? Like personal computers, phones can be compromised by malware. For example, the Hummingbad virus infected <a href="https://www.wired.co.uk/article/hummingbad-malware-10-million-android-devices" target="_blank" rel="noopener">ten million</a> Android devices within a few months of its creation in 2016, and put as many as <a href="https://www.theguardian.com/technology/2016/jul/06/what-is-hummingbad-malware-android-devices-checkpoint" target="_blank" rel="noopener">85 million</a> devices at risk. Typically, a phone virus works the same way as a computer virus: a malicious code infects your device, replicates itself and spreads to other devices by auto-messaging others in your contact list or auto-forwarding itself as an email. A virus can limit your phone’s functionality, send your personal information to hackers, send your contacts spam messages linking to malware, and even allow the virus’s operator to “spy” on you by capturing your screen and keyboard inputs, and tracking your geographical location. In Australia, Scamwatch received <a href="https://www.scamwatch.gov.au/news-alerts/missed-delivery-call-or-voicemail-flubot-scams" target="_blank" rel="noopener">16,000 reports</a> of the Flubot virus over just eight weeks in 2021. This <a href="https://suretyit.com.au/blog/what-is-the-flubot-virus/" target="_blank" rel="noopener">virus</a> sends text messages to Android and iPhone users with links to malware. Clicking on the links can lead to a malicious app being downloaded on your phone, giving scammers access to your personal information. Flubot scammers regularly change their <a href="https://www.bitdefender.com/blog/labs/new-flubot-and-teabot-global-malware-campaigns-discovered" target="_blank" rel="noopener">target countries</a>. According to cyber security firm Bitdefender, FluBot operators targeted Australia, Germany, Poland, Spain, Austria and other European countries between December 1 2021 and January 2 of this year. Is either Apple or Android more secure? While Apple devices are generally considered more secure than Android, and <a href="https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=6637558" target="_blank" rel="noopener">less prone</a> to virus attacks, iPhone users who “jailbreak” or modify their phone open themselves up to security vulnerabilities. Similarly, Android users who install apps from outside the Google Play store increase their risk of installing malware. It’s recommended all phone users stay on guard, as both Apple and Android are <a href="https://www.forbes.com/sites/zakdoffman/2021/03/16/iphone-12-pro-max-and-iphone-13-not-more-secure-than-google-and-samsung-android-warns-cyber-billionaire/?sh=596442d623f8" target="_blank" rel="noopener">vulnerable</a> to security risks. That said, phones are generally better protected against viruses than personal computers. This is because software is usually installed through authorised app stores that vet each app (although some malicious apps can occasionally slip through <a href="https://blog.pradeo.com/spyware-facestealer-google-play" target="_blank" rel="noopener">the cracks</a>). Also, in comparison to computers, phones are more secure as the apps are usually “<a href="https://source.android.com/security/app-sandbox" target="_blank" rel="noopener">sandboxed</a>” in their own isolated environment – unable to access or interfere with other apps. This reduces the risk of infection or cross contamination from malware. However, no device is entirely immune. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/459712/original/file-20220426-12-4550kz.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/459712/original/file-20220426-12-4550kz.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/459712/original/file-20220426-12-4550kz.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=338&fit=crop&dpr=1 600w, https://images.theconversation.com/files/459712/original/file-20220426-12-4550kz.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=338&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/459712/original/file-20220426-12-4550kz.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=338&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/459712/original/file-20220426-12-4550kz.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=424&fit=crop&dpr=1 754w, https://images.theconversation.com/files/459712/original/file-20220426-12-4550kz.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=424&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/459712/original/file-20220426-12-4550kz.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=424&fit=crop&dpr=3 2262w" alt="A smartphone with a virus alert warning is held up by a hand in front of a dark background." /></a><figcaption>Apple devices are generally considered more secure against malware than Android devices, but they’re still at risk.

What hackers can do with just your phone number

Your number can be used in many malicious ways Your phone number is an easy-to-find key that can be used by hackers and scammers to unlocking your personal data. They can also use your number in many other malicious ways. I used to think that maybe, at best, a person could possibly find my name and address using my phone number. I was wrong. Recently, someone I don’t know used my phone number to find out the private details of my life, then emailed me everything they had discovered. With just my phone number this person found out where I live, my previous addresses, information on if I’ve ever been evicted, some personal financial information, a map of my neighbourhood, and my birth date. They even found the only speeding ticket I’ve ever had, way back in 2006. It was disturbing, to say the least. I felt, and still feel, violated. I reported the person to the social media site they contacted me through and blocked them, but is there more I can do? After contacting some security experts for their take, it turns out that finding important details about someone’s life with just a phone number is incredibly alarmingly easy…and profitable. “In the wrong hands, your phone number can be used to steal your identity and take over almost every online account you have,” Veronica Miller, cybersecurity expert at VPN overview, tells Reader’s Digest. There are several ways a hacker can use a phone number to turn your life upside down. Here are some ways criminals can target you. Data mining the easy way The easiest way to use your phone number maliciously is by simply typing it into a people search site. Sites like these can reveal personal information about you in less than a few seconds, according to tech expert Burton Kelso. People search sites, purchase your personal information and then sell it to people who want your data, like hackers with your phone number. The information found through these sites includes your address, bankruptcies, criminal records and family member’s names and addresses. All of this can be used for blackmail, stalking, doxing or identity theft. Rerouting your number Another tactic is to contact your mobile carrier provider claiming to be you, said Miller. Then, the hacker can make it so your number routes to their phone. From there, the hacker will log into your email account. Of course, they don’t have your password, but they don’t need it. They just click “Forgot your password” and get the reset link sent to their phone that now uses your phone number. Once the hacker has access to your email account, it’s easy to gain access to any of your accounts. While many service providers have some security features to prevent scammers from switching phones, if the person has your phone number, though, they may be able to find enough information about you to get past the security questions. Spoofing There were billions of scam calls in 2019, according to data collected by YouMail, and scammers are getting smarter. Now they are using a technique called spoofing to make it easier to scam you. Spoofing is when someone makes your phone number pop up on a caller ID when it really isn’t you that’s making the call. For example, a scammer once spoofed my daughter’s phone number to make me think she was calling me. The goal was to trick me into answering the phone. It worked, because what if it was an emergency and my daughter needed me? When a scammer gets you to pick up, they have the chance to trick you into whatever scheme they’ve come up with, like tricking you into giving them your credit card information. It doesn’t take much to spoof a phone number. There are apps and websites that allow scammers to simply type in a phone number and make a call. It’s super easy and quick, which makes it appealing to scammers. Texting scams Scammers can also use your phone number to send you malicious text messages. This type of scam is called ‘smishing’, according to digital privacy expert Ray Wallsh. In these texts, scammers can send links that can infect your phone with malware that can steal your personal information, or they can straight-up scam you by pretending to be your bank, the IRS, or your doctor. Posing as someone you trust, the scammers will then try to trick you into giving them personal information and credit card numbers. How to protect yourself All of the experts I contacted recommended that to combat your phone number being misused, share it as little as possible. “Many apps and services require a cell number for verification at sign up. By handing your data to these apps, services and businesses, you increase the likelihood that your phone number will be passed on to third parties and data aggregators,” said Wallsh. Limit giving out your phone number to friends and family and your doctor. For everyone else, you need a virtual number that can forward calls to your phone so you don’t need to give anyone your real number that is linked to your personal information. You can set up a virtual number for free through Google Voice or through services like Burner. Also, never click on links sent to you in text messages, even if they look like they were sent from a trusted contact. If your bank, credit card company, doctor or service you use contacts you through text, call them using a verified number from their website to confirm the communication was truly sent from them to avoid malware or scams. To protect yourself from hackers rerouting your number, ask your mobile carrier to add an extra layer of security like a password or PIN number to your account, advises Miller. All of these steps can help keep your personal information private, but it only works to a point. Your personal data has probably already been sold to people search sites and while you can send these sites requests to remove your information, it’s a huge task. Plus, the site may simply repost your information later. So, in the end, there may not be a way to completely prevent hackers and scammers from getting access to your phone number. Knowing what someone can do with your number, though, can help you avoid scams and protect your information from being more widely spread.

Here’s how to charge your phone faster

Switch into aeroplane mode A quick way to keep the battery from draining so quickly is to switch it to plane mode. You won’t be able to get texts or search online, but you’ll save power because your phone won’t be constantly searching for a cellular or WiFi connection. Turn it off There’s no better way to make sure all the power goes directly to your battery than making sure there’s no competition for it by switching it off. Alternatively, leave your phone in low power mode. You can find it in settings. Sometimes it’s known as battery saver mode. Plug it into a wall socket The USB port of your computer may be convenient when you’re working remotely, but an outlet will charge your phone faster. This is because USB ports usually only charge at 0.5 amps, so it’s going to take twice as long to charge your phone than the one amp power adapter it came with. Use a powerful wall charger It can also be helpful to have a charger that works faster than the one that comes with your phone, such as a rapid charger. Just find an outlet, plug it in in, and connect it to your phone. Keep a charged battery pack handy For those situations when you know you’re going to be away from a traditional power source, buying a battery pack is a good idea. Just make sure to plan for it in advance, so you can charge the battery pack before you leave. Get your phone out of the sun Avoid exposing your phone to temperatures above 35º Celsius. The heat can damage your battery capacity, and your phone’s software may limit charging to about 80% when the phone gets hotter than the recommended temperature. Take your phone out of the case If you notice that your phone gets hot when you charge it, take it out of its case. “Charging your device when it’s inside certain styles of cases may generate excess heat, which can affect battery capacity,” according to Apple. Clean out your lightning port The problem may not be with the power of your battery itself. Over time, lint and dust can accumulate in your lightning port (that’s where you plug your charger into your phone) and clog it. CNET recommends turning your phone off and using a toothpick to gently remove any debris from the port. Then plug in your charger again and see if it works better. Get a powerful wireless charger For a quick juice boost, look for a charger with high wattage. “The higher the number of watts, the faster your device will charge,” Macworld reports. The typical chargers that come with iPhones and older Androids carry one amp of current and produce five watts of power, according to the consumer blog Techlicious. But “new rapid chargers with technology such as Quick Charge support two amps and 12 watts or more, potentially charging your phone up to four times faster.” Get a wireless charging pad Though wired charging is faster, wireless charging is also a good option. Invest in a charging case For an ongoing solution to ensure you can charge your phone quickly, consider getting a charging case. Some models can extend your battery’s life for 22 hours. They come in a range of prices and designs.

Cracking the code of unbreakable phone screens

<div class="copy"> Unbreakable phone screens might seem too good to be true, but some chemical engineers reckon they’ve cracked the secret, developing a new material that combines glass with nanocrystals to make a resilient screen that would produce high-quality images in phones, LEDs and computers. The breakthrough substance could even be used to make phone screens that double as solar panels. The technology revolves around <a rel="noreferrer noopener" href="https://cosmosmagazine.com/science/overcoming-atomic-level-perovskite-defects/" target="_blank">perovskites</a>: nanometre-sized crystals that have a range of exciting electrical properties, making them prime candidates for better solar cells, LEDs and touchscreens. While perovskites have had a few early commercial successes, their physical properties have mostly stopped them from getting far out of the lab. “The stability of perovskites is the most difficult challenge which has hindered their commercialisation,” says Professor Lianzhou Wang, a materials scientist at the University of Queensland and co-author on a paper describing the research, <a rel="noreferrer noopener" href="http://www.science.org/doi/10.1126/science.abf4460" target="_blank">published</a> in Science. Lead author Dr Jingwei Hou, also from UQ, says the material is “super sensitive to almost everything – oxygen, water, gas, temperature, and even sensitive to light. “I think it’s a fantastic material, but it doesn’t really make sense if we want to use it on a solar panel, or display, if it’s sensitive to light.” The researchers have overcome this sensitivity by figuring a way to encase lead-halide perovskites in glass. “We created a lot of very small, nano-sized pores within the glass,” explains Hou. “That offers a very nice host material environment for the perovskite. “If we just put those very small nanocrystals within the pores, they will be not only stabilised against all of the external environment…it also makes the perovskite somewhere between 100 to 1000 times more efficient.” At the level of nanometres, the material resembles a chocolate chip cookie. “The perovskite nanocrystals are the chocolate chips, and the glass surrounds them,” says Hou. The material is also much more durable than normal glass. “Conventional glass is so brittle [because] it’s really dense. If you zoom in and look at the molecular structure, it’s silicon, aluminium, oxygen – very densely packed atoms,” says Hou. “Once you apply any pressure or any mechanical force to it, there’s no way to get it relaxed, and that’s what leads to the breakage of chemical bonds.” The pores, on the other hand, allow the glass to absorb more stress. “This is really a kind of platform technology,” says Hou. “The pore size can be tuned, the chemistry can be tuned. So that means it can be used to host a different type of perovskite.” In the paper, the international team of researchers – who are based at the University of Leeds and the University of Cambridge in the UK, and Université Paris-Saclay in France – demonstrate several different types of “lead halide perovskite and metal-organic framework glasses”, all of which they’ve been able to create. As well as their potential applications in screens and LEDs, the glasses could be used to make higher-quality X-ray images and more efficient solar panels. “We’re looking at trying to combine a solar panel with a display,” says Hou. “Think about mobile phones, for example – when you use it, it will become a display. When you don’t use it, put it in the sunlight, it will charge the battery. So it’s one device for two functions.” Manufacture of the material is scalable, according to Hou, and the researchers are currently looking at building prototype devices with it. “We’re really confident that we’ll be able to generate devices in the next stage,” says Hou. “We are also looking for some industrial collaborators who are really interested in bringing this exciting material into the real world.” Image credits: Shutterstock  <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=171112&title=Cracking+the+code+of+unbreakable+phone+screens" alt="" width="1" height="1" />  </div> <div id="contributors"> This article was originally published on <a rel="noopener" href="https://cosmosmagazine.com/technology/materials/unbreakable-phone-screens/" target="_blank">cosmosmagazine.com</a> and was written by Ellen Phiddian. </div>

The iconic Nokia 3310 turns 21

It is widely known as the toughest substance on Earth, and became a staple in international households. The Nokia 3310 mobile phone was released in September 2000, and is now celebrating its 21st anniversary. The device boasted a black and white display, enough memory to save eight numbers in call logs, and zero capabilities that smartphones offer today. The phone became an iconic early 2000s reference with many millennials referring to the device as “a brick”, as the body seemed completely unbreakable. Some people may even remember the miraculous tale of a Nokia 3310 surviving a fall from the second storey of a building completely unscathed. Another classic feature of the device was the simple, but completely addictive game of Snake, that would keep users entertained for hours. Nokia 3310 owners could also customise their own ringtones, to play slightly different variations of the same tune when a call was incoming. Many phone users today still think of the device’s extraordinary battery life, which could last over two days: completely winning against modern day smartphone batteries that last a mere 12 hours (if you’re lucky). The phone received so much love and attention over the years that a 4G version of the Nokia 3310 was released a few years ago, but the buzz of the revival version didn’t garner as much attention as the original. With modern day smartphones having unlimited capabilities, it is interesting to see why the Nokia 3310 still gets recognised on a global scale. From all its unique quirks and early 2000s charm, it has mostly become a pop culture staple and distinct timestamp of the technology revolution. Image credit: Shutterstock

The real reason we have to use flight mode on a plane

With flying for vaccinated passengers looking like it will happen soon, we could be back on a plane some time soon and putting our phone on flight mode is always one of the things we have to do when we get in our seat. Most of us think if we don’t do this as soon as possible, there could be a major problem somehow but we don’t really know why we have to do it. Sometimes we think - does it even matter? But now, thanks to TikTok, we finally have the answers from a flight attendant called Cierra Mistt who’s shared the real reason we must put our phone on flight mode. Already her TikTok video has gathered more than 1.7 million views. As Mistt says in her video: “There are approximately 45,000 flights that happen every single day, with about 2.9 million passengers on board,” she explains in the video. “And how does all this flying happen successfully? Believe it or not, pilots actually aren’t in charge of flying.” Mistt explains that although the pilot is operating the plane, it’s the communication between the ground and the pilot which is even more critical. “From the moment the boarding door closes to the moment we’re landing, the pilots are following specific instructions given to them by a group of people on the ground called Air Traffic Control,” she says. “In order for the pilot to be able to communicate with air traffic control, they use frequencies. Yep, just like the frequencies we use to send messages, stream video and insta-stalk our fave influencers on our phones,” she adds. Cierra goes on to explain that sometimes these frequencies collide, causing a complete loss of signal. “Picture how bad it would be for a pilot, who is taking directions from ATC on the ground to all of a sudden lose signal and [need to] start flying blindly. All because the frequency of a passenger’s phone has intercepted it.” Many commented, thanking her for the explanation Mistt received a lot of comments and thanks for the fact that she finally explained the full reason behind the need to use flight mode. As well, there were one or two sceptics and clarifications from experts in the field, particularly around the terminology used in the video. One electrical engineer said the real reason for flight mode was “unintended radio waves emitted by phones and other devices” or “intended radio waves being inadvertently picked up by the pilot’s equipment”. He added that nowadays, “our devices don’t emit or accept unintended waves as much” and questioned whether flight mode was still “absolutely necessary”, but added: “Out of caution, do it.” So, after watching this video, it’s great that we know more about why we need to use flight mode – and given it’s such a small, simple thing to do, it hardly seems like a big thing to ask of passengers.

If you can read this headline, you can read a novel. Here’s how to ignore your phone and just do it

Public anxiety about the capacity of digital-age children and young adults to read anything longer than a screen grab has come to feel like moral panic. But there is plenty of evidence to suggest we must take such unease seriously. In 2016, the US National Endowment for the Arts reported the <a href="https://www.washingtonpost.com/news/wonk/wp/2016/09/07/the-long-steady-decline-of-literary-reading/">proportion of American adults</a> who read at least one novel in 2015 had dropped to 43.1% from 56.9% in 1982. In 2018, a <a href="https://theconversation.com/why-it-matters-that-teens-are-reading-less-99281">US academic reported</a> that in 1980, 60% of 18-year-old school students read a book, newspaper or magazine every day that wasn’t assigned for school. By 2016, the number had plummeted to 16%. Those same 12th graders reported spending “six hours a day texting, on social media and online”. American literacy expert and neuroscientist Maryanne Wolf describes the threat screen reading poses to our capacity for “the slower cognitive processes such as critical thinking, personal reflection, imagination, and empathy that are all part of deep reading”. She <a href="https://www.scribd.com/document/386632978/Excerpt-from-Reader-Come-Home-by-Maryanne-Wolf">asks</a>: <blockquote> Will the mix of continuously stimulating distractions of children’s attention and immediate access to multiple sources of information give young readers less incentive either to build their own storehouses of knowledge or to think critically for themselves? </blockquote> But rather than taking up defensive positions on either side of the digital-analogue reading divide, Wolf encourages us to embrace both. As parents and teachers we can help our children develop a <a href="https://now.tufts.edu/articles/slow-down-reader">bi-literate reading brain</a>. There are several ways we can do this. Reading pathways Reading is a learned skill that <a href="https://pdfs.semanticscholar.org/71cf/5d3dd4a5037003f0bca787874f2d68077cf9.pdf">requires the development</a> of particular neural networks. And different reading platforms encourage the development of different aspects of those networks. Screen-reading children, immersed from toddlerhood in the pleasures and instant gratification of skimming, clicking and linking, develop cognitive skills that make them adept power browsers, good at the useful ability to scan for information and analyse data. But Wolf suggests this kind of reading “can short-circuit the development of the slower, more cognitively demanding comprehension processes that go into the formation of deep reading and deep thinking.” Unless the cognitive skills required for deep reading are similarly developed and nurtured, new generations of readers – distracted by the ready availability of digital information – may not learn to venture beyond the shallows of the reading experience. <a href="https://images.theconversation.com/files/309816/original/file-20200114-103966-4rr4lz.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/309816/original/file-20200114-103966-4rr4lz.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="" /></a> We can help children gain a love of reading on paper from an early age. from shutterstock.com Along with others concerned with early childhood education Wolf advises encouraging paper literacy from infancy. She doesn’t recommend forbidding devices. Instead we should regularly turn them off and make the time and space to read books on paper with children. We can model our own reading practices by setting aside our own smart phones to lose ourselves in a book. But how can secondary and tertiary teachers help inexperienced readers? The problem is likely to be aliteracy, meaning students can read but they choose not to because they don’t see it to be important for learning. And because they haven’t read much, it’s hard work. The problem can seem intractable. But it can be done. Turn off the phone and read My first venture into helping tertiary students read better was a 2011-2013 <a href="https://ltr.edu.au/resources/CG10_1566_Kennedy_Toolkit_2013.pdf">cross-university government-funded project</a> that set out to foster what we termed “reading resilience”. We found if students were persuaded to prioritise reading as they did a test or an essay, they would invest the time to get into the zone that is the other world of the text. We complemented complex texts with a guide that encouraged students to think critically as they read and to keep going when the language seemed impenetrable, the narrative incomprehensible (or dull) and the length endless. Or when the siren call of the smart phone became irresistible. They experimented with switching off their devices for blocks of two hours while they simply read. And they did read. Students prioritised this difficult work because we rewarded pre-class reading with marks. Some classes uploaded one-page, carefully argued responses; others answered complex feedback-rich quizzes. <a href="https://images.theconversation.com/files/309826/original/file-20200114-103982-1pgksj5.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/309826/original/file-20200114-103982-1pgksj5.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="" /></a> Can you ignore your phone for two hours and keep reading? from shutterstock.com I surveyed a large first-year introduction to literary studies at the University of Queensland in 2013 before testing a version of the same “reading resilience” course in 2014. The rise in reading rates was exponential. The number of students who completed all ten primary texts (including the poem Beowulf and Toni Morrison’s Beloved) more than tripled, and the number who completed the ten accompanying secondary texts (selected chapters from an <a href="http://site.iugaza.edu.ps/ahabeeb/files/2012/02/An_Introduction_to_Literature__Criticism_and_Theory.pdf">introduction to literary theory and criticism</a>) went up by more than six times. Reported student satisfaction for this course from 2008 to 2012 had ranged between 64% and 75%. Once reading resilience was introduced, many complained about the reading load yet the level of overall satisfaction jumped to 86%. We can all do it It’s not just readers raised in a digital-age who have difficulty with long-form text. Have you have lost the skill of deep reading? Are you finding it increasingly difficult to stay with, say, a literary novel? You are not alone. Wolf, who despite having two degrees in literature, confesses to the shocking discovery that <a href="https://www.theverge.com/2018/8/27/17787916/reader-come-home-maryanne-wolf-neuroscience-brain-changes">recently she found herself</a> struggling to stick with a beloved Herman Hesse novel. We too can switch off our devices and set aside a space and time to revitalise the neural pathways that once made us immersive readers. As Wolf <a href="https://pdfs.semanticscholar.org/71cf/5d3dd4a5037003f0bca787874f2d68077cf9.pdf?_ga=2.263432204.1683872892.1573681450-1249221942.1573681450">argues</a>, the skills of “deep reading” that involve “slower, more time-consuming cognitive processes […] are vital for contemplative life”. Deep readers are likely to be more thoughtful members of the community at a time when good citizenship may never have been more important.<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; text-shadow: none !important;" src="https://counter.theconversation.com/content/116524/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/judith-seaboyer-131588">Judith Seaboyer</a>, Senior Lecturer, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Billions are pouring into mobility technology – will the transport revolution live up to the hype?

Over the past decade almost <a href="https://files.pitchbook.com/website/files/pdf/PitchBook_Q4_2019_Emerging_Tech_Research_Mobility_Tech_Executive_Summary.pdf">US$200 billion</a> has been invested globally in mobility technology that promises to improve our ability to get around. More than US$33 billion was invested last year alone. Another measure of interest in this area is the <a href="https://travelandmobility.tech/lists/unicorns/">number of unicorns</a>, which has doubled in the past two years. A unicorn is a privately held startup company valued at US$1 billion or more. In early 2018 there were 22 travel and mobility unicorns. By last month the number had grown to 44. The top categories in the mobility area are: ride hailing, with 11 unicorns (25.0%); autonomous vehicles, with ten (22.7%); and micromobility, with three (6.8%). The remaining 20 unicorns are in the travel category (hotels, bookings and so on). Mobility technology is more than just autonomous vehicles, ride hailing and e-scooters and e-bikes. It also includes: electrification (electric vehicles, charging/batteries); fleet management and connectivity (connectivity, data management, cybersecurity, parking, fleet management); auto commerce (car sharing); transportation logistics (freight, last-mile delivery); and urban air mobility. Promised solutions, emerging problems Much of the interest in mobility technology is coming from individuals outside the transport arena. Startups are attracting investors by claiming their technology will solve many of our transport problems. Micromobility companies believe their e-scooters and e-bikes will solve the “<a href="https://ascelibrary.org/doi/abs/10.1061/9780784413210.007">first-mile last-mile</a>” problem by enabling people to move quickly and easily between their homes or workplaces and a bus or rail station. While this might work in theory, it depends on having <a href="https://theconversation.com/fork-in-the-road-as-danish-and-dutch-style-cycle-routes-spread-19744">safe and segregated bicycle networks</a> and <a href="https://theconversation.com/people-love-the-idea-of-20-minute-neighbourhoods-so-why-isnt-it-top-of-the-agenda-131193">frequent and widely accessible public transport</a> services. Ride-hailing services might relieve people of the need to own a car. But <a href="https://www.som.com/ideas/publications/som_thinkers_the_future_of_transportation">there is evidence</a> to suggest these services are <a href="https://www.wsj.com/articles/the-ride-hail-utopia-that-got-stuck-in-traffic-11581742802">adding to traffic congestion</a>. That’s because, unlike taxis, more of their time on the road involves travelling without any passengers. Navigation tools (Google Maps, Apple Maps, Waze) have <a href="https://en.wikipedia.org/wiki/Google_Maps">been around longer</a> than most other mobility technologies and are meant make it easier to find the least-congested route for any given trip. However, <a href="https://people.eecs.berkeley.edu/~theophile/docs/publications/Cabannes_19_ACM.pdf">research</a> suggests these tools might not be working as intended. The <a href="https://www.som.com/ideas/publications/som_thinkers_the_future_of_transportation">backlash</a> against them is growing in some cities because traffic is being directed onto neighbourhood streets rather than arterial roads. Autonomous vehicles have the goal of reducing injuries and deaths from car crashes. Only a few years ago many bold predictions were being made that these self-driving vehicles would be having positive impacts by now, but this hasn’t happened. The enthusiasm for autonomous vehicles has cooled. <a href="https://www.vtpi.org/avip.pdf">Some now believe</a> we won’t see many of the social benefits for decades. The final mobility tech area is known as mobility as a service (<a href="https://en.wikipedia.org/wiki/Mobility_as_a_service">MAAS</a>). It’s basically a platform designed to make better use of existing infrastructure and transport modes. MAAS begins with a journey planner that is linked to one-stop payment for a range of mobility services – ride-hailing, e-scooters, e-bikes, taxis, public transport, and so on. MAAS is the newest entrant in the mobility tech field. It has attracted US$6.8 billion to date, but is expected to grow to <a href="https://www.marketsandmarkets.com/Market-Reports/mobility-as-a-service-market-78519888.html">over US$100 billion by 2030</a>. This idea is creating great enthusiasm, not only among private entrepreneurs, but also in the public sector. It’s too early to know whether it will improve transportation. 3 trends are driving investment So, why do venture capitalists <a href="https://www.forbes.com/sites/johnfrazer1/2019/03/11/new-mobility-worth-billions-venture-capital-thinks-so/#198cda2247d8">continue to show so much interest</a> in mobility technology startups despite poor company performance to date? It appears they believe personal mobility will become increasingly important. <a href="https://www.forbes.com/sites/johnfrazer1/2019/03/11/new-mobility-worth-billions-venture-capital-thinks-so/#198cda2247d8">Three trends</a>support this belief. First, urban dwellers increasingly value the ability to move around easily. It’s thought to be a key ingredient for a liveable city. The problem is public transport is often not very good, particularly in the US and in outer suburbs in Australia. This is due to historically low funding relative to roads. The prospect of more funding and better public transport services in the future is not good. In part that’s because many <a href="https://www.vox.com/2015/8/10/9118199/public-transportation-subway-buses">view public transport as welfare</a> and not an essential public service. Thus, if cities want to become more liveable and competitive, they must look beyond government-funded public transport for other mobility alternatives. The second trend is declining vehicle ownership. Since 1986 US sales of car and light trucks per capita have dropped by <a href="https://www.advisorperspectives.com/dshort/updates/2020/02/04/vehicle-sales-per-capita-our-latest-look-at-the-long-term-trendh">almost 30%</a>. In Australia, new car sales <a href="https://www.budgetdirect.com.au/car-insurance/research/australian-car-sales-statistics.html">remained relatively constant</a> over the past decade, but a <a href="http://www.roymorgan.com/findings/7982-new-vehicle-purchase-intention-march-2019-201905240039">decline since 2017 is expected to continue</a>. These trends are due in part to the cost of owning a vehicle, but also because of a growing view that owning a car may not be necessary. This brings us to the third trend, which involves demographics and the <a href="https://theconversation.com/delay-in-getting-driving-licences-opens-door-to-more-sustainable-travel-57430">post-millennial desire for access to mobility</a> services <a href="https://theconversation.com/car-ownership-is-likely-to-become-a-thing-of-the-past-and-so-could-public-transport-110550">rather than vehicle ownership</a>. These trends, combined with expectations of an upward trend in prices of these services, suggests there may be good times ahead for ride-hailing and micromobility companies. It also means venture capital funding for these startups will not be diminishing in the near future. The future of transport isn’t simple Transport systems are multifaceted. No one single app or technology will solve the challenges. And, as we are discovering, some of the purported solutions to problems might actually be making the situation worse. If the goal is to get people out of their cars (for <a href="https://theconversation.com/designing-suburbs-to-cut-car-use-closes-gaps-in-health-and-wealth-83961">better health and quality of life and a better environment</a>), this will require more than a technology. Better infrastructure and public policies (including better integration of land uses and transport to reduce the need for transport) will be required – <a href="https://theconversation.com/three-charts-on-why-congestion-charging-is-fairer-than-you-might-think-124894">congestion pricing</a>being one of those. That is not to say technological innovations are not welcome as part of the solution, but they are just that … “part” of the solution. Written by Neil G Sipe.
