Is it OK to leave device chargers plugged in all the time?

<div class="theconversation-article-body"> How many chargers do you own? We’re surrounded by rechargeable electronic devices – mobile phones, laptops, smart watches, headphones, e-bikes and more. You might have a phone charger plugged in next to your bed without ever bothering to switch it off at the wall or unplugging it when not in use. The same might go for a laptop charger by your desk. But is that risky to do? And are there hidden costs associated with leaving chargers plugged in all the time? <h2>What’s inside a charger?</h2> Naturally, not all chargers are the same. Depending on the application and power requirement, their internal structure can range from very simple to complex. However, a typical charger takes in the AC (alternating current) from the wall plug and converts it to a low-voltage DC (direct current) suitable for your device’s battery. To understand the difference between DC and AC, consider the flow of electrons in a wire. In a DC circuit, electrons move in one direction and keep rotating in the circuit. In an AC circuit, electrons doesn’t circulate and only move back and forth. The reason for why we use both types of current goes a long way back, to the time when inventors Thomas Edison and Nicola Tesla battled over which type <a href="https://www.history.com/articles/what-was-the-war-of-the-currents">would become the default standard</a>. Today, we are <a href="https://www.energy.gov/articles/war-currents-ac-vs-dc-power">still stuck between both</a>. Electricity is traditionally generated in AC form, but modern appliances and batteries require the DC form. This is why almost every electrical appliance comes with an AC–DC converter. To do the conversion from AC to DC, a typical charger needs several electrical components such as a transformer, a circuit for doing the actual conversion, filtering elements to enhance the quality of output DC voltage, and control circuitry for regulation and protection. <h2>Chargers consume power even when not charging</h2> “Vampire power” is real. If you leave it plugged in, a charger will continuously draw a small amount of power. Part of this power is used to keep the control and protection circuits running while the rest is lost as heat. When we look at an individual small charger, the vampire power – also known as standby power – is negligible. However, if you add up all the chargers in your home for various devices, over time the wasted energy can be significant. Standby power is not exclusive to chargers, either; other electronic devices such as TVs draw a little bit of standby power, too. Depending on how many things you leave plugged in, over the course of the year it could amount to several kilowatt hours. That said, modern chargers are designed to minimise standby power consumption. These chargers come with smart power management components that keep them in sleep mode until an external device attempts to draw power. <h2>There are other risks, too</h2> Chargers wear out over time when electricity flows through them, particularly when the electricity grid voltage temporarily rises above its rated value. The electricity grid is a chaotic environment and various voltage rise events happen from time to time. Leaving your chargers exposed to these events will shorten their life. This premature ageing shouldn’t be alarming for modern devices, thanks to their improved design and control. But it is particularly concerning for cheap, uncertified chargers. These often lack appropriate levels of protection and can be a fire hazard. <h2>How should I treat my chargers?</h2> Although modern chargers are generally very safe and should be drawing minimal standby power, consider unplugging them anyway – if convenient. If a charger gets warmer than usual, makes noise, or is damaged in any way, it is time for a replacement. And it definitely shouldn’t be left plugged in.<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/255016/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> By <a href="https://theconversation.com/profiles/glen-farivar-2373201">Glen Farivar</a>, Lecturer in Power Electronics, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to get started investing later in life

For some people – particularly women – investing may not have been an option until now, constrained by a lack of income while raising children or low incomes leaving nothing to invest once the bills were paid. Others find a new-found need to invest later in life, such as after a separation, inability to work through illness or injury, or the sudden death of their partner. No matter your reason for exploring investing later in life, the following pointers will get you on your way to building financial independence and a comfortable retirement. Update your strategy When was the last time you updated your spending and investment plan (or household budget)? It may have been before the kids left home, your mortgage was paid off, or you began transitioning into part-time retirement. If so, your living costs have changed significantly – work expenses, home energy consumption, groceries etc. Furthermore, your goals, healthcare and lifestyle needs may also have changed. Update your strategy to align with your current goals, values, income and spending habits. Only then will you understand how much you can afford to invest and where to direct those funds. Right-size your superannuation In your later years, super is likely to be front of mind. Ensure this investment works its hardest for you by scrutinising its: • Structure: retail or industry fund? SMSF? Each has its own costs and benefits to contemplate. • Investments: reexamine the types of assets held, level of diversification and risk weighting. • Insurances: do you have adequate life, permanent disability and income protection cover? • Take advantage of superannuation strategies you may not be aware of Unlock home equity The biggest source of money you likely have at this stage of life is equity in your home. This can be used to invest with minimal impact on your everyday finances. In fact, unused equity is effectively dead money (until you sell the property). I always urge caution on reverse mortgages. In theory, they seem like a great way of unlocking equity without saddling you with regular repayments. However, they typically: • accumulate more debt. • have higher interest rates than standard mortgages. • only grant access to a portion of your equity. • can restrict your options to downsize later. • could leave you with no remaining equity when you sell the property or nothing to leave to your benefactors when you pass away. Consider downsizing An alternative to refinancing is downsizing from the family home. As well as unlocking money for investing, you benefit from lower upkeep costs (and cleaning!) on a smaller property and can make a lifestyle change at the same time (moving nearer to family, away from bustling cities, or into supported care if required). Additionally, you may be able to use part of the sale proceeds (up to $300,000) to turbocharge your super with a one-off <a href="https://www.ato.gov.au/individuals-and-families/super-for-individuals-and-families/super/growing-and-keeping-track-of-your-super/how-to-save-more-in-your-super/downsizer-super-contributions" target="_blank" rel="noopener">downsizer contribution</a>. Examine pension impacts Investing can impact your ability to claim the age pension when you retire, and how much you receive. This often comes to bite people who unlock equity in their home to invest, without realising that doing so means the money suddenly counts towards the pension means test. Before doing anything, methodically weigh up which will leave you financially better off – claiming a full or part pension, or self-funding your retirement through investments. Minimise tax Hefty tax bills can easily wipe out any investment returns, making tax a crucial factor in your decision-making. Potential tax considerations to factor into your strategy include: • Determining the most tax-effective ownership structure (e.g. do you invest in your or partner’s name? Through your super? Through a trust or company? • Incorporating stamp duty into purchase costs. • Ensuring there is enough profit from the sale of an investment to cover Capital Gains Tax (CGT) and income tax liabilities before deciding to sell. • Timing a sale to fall within the optimal financial year (e.g. in a year where your taxable income is lower or when relevant tax changes come into effect). Invest in knowledge Later in life, you have fewer working years remaining to recover any losses. Given the far-reaching implications of investing, I highly recommend first speaking to a financial adviser. Many times the fees are paid for in initial tax savings. They can help you maximise your returns, minimise your tax, ensure you don’t inadvertently leave yourself worse off and give you peace of mind. After all, the whole point of investing is to make money. And, without current professional advice, you simply don’t know what you don’t know!

Pilot explains why airplane mode on phones is so important

A seasoned pilot has explained the real reason why your phone needs to be on airplane mode for the duration of your next flight. The pilot broke down the precaution in a video he posted to TikTok, with the explanation racking up over 2 million views. “The plane mode button on your phone is not a conspiracy,” declared the pilot, before reassuring passengers that using your phone onboard won't cause the plane to “fall out of the sky” or even really “mess with the systems on board”. However, if too many flyers choose to use their phones all at once, it can inadvertently mess with the pilots’ radio communications with the control tower. “If you have an aircraft with 70, 80, 150 people on board, and even three or four people’s phones start to try to make a connection to a radio tower for an incoming phone call, it sends out radio waves,” the captain explained. “There’s the potential that those radio waves can interfere with the radio waves of the headset that the pilots are using.” He recalled a recent flight where he was using his headset to get “clearance on which way to go” and the message interference made it feel like there was a “mosquito” in his ear. “It’s definitely not the end of the world but it’s pretty annoying when you’re trying to copy down instructions and it sounds like there’s a wasp or something flying around,” the pilot declared. “So if you’re ever curious why you’ve got to put on plane mode, that’s why.” Image credits: Shutterstock

How an AI grandma is combating phone scams

Fraudsters frequently target the elderly for scams, so one company took matters into their own hands and created an AI grandmother who tricks phone scammers. At first glance Daisy looks like every other grandmother, with hobbies like knitting, a cat named Fluffy and loves talking about her family among other things. However, the AI chatbot is designed to trick phone scammers into thinking they are speaking to a real person. The AI, created by British mobile phone company O2, is designed to combat fraud, and while Daisy doesn't intercept any calls, she has a list of phone numbers used by UK scammers. Daisy's mission “is to talk with fraudsters and waste as much of their time as possible with human-like rambling chat to keep them away from real people,” the company said in a statement unveiling Daisy earlier this month. Her tactics have kept “numerous fraudsters on calls for 40 minutes at a time." Developed in partnership with London advertising agency VCCP, Daisy uses a custom language model to hold autonomous conversations with scam callers in real time. Her voice was modelled on a staff member's grandmother. “Whilst anyone can be a victim of a scam, criminal fraud gangs often target the elderly so we leaned into scammers’ own biases to create an AI granny based on a real relative of a VCCP employee,” the agency said in a statement. “Over the course of many hours of scam calls she’s told meandering stories of her family, talked at length about her passion for knitting and provided false personal information including made-up bank details.” Last year, Virgin Media O2, blocked more than £250 million ($A487.5 million) in suspected fraudulent transactions, which is roughly equivalent to stopping one every two minutes. According to the telecommunications company, Daisy was developed in response to research revealing that the top reason why the British public wouldn’t bait scammers themselves is because they don't want to waste their own time. “With scammers operating full-time call centres specifically to target Brits, we’re urging everyone to remain vigilant,” commented Murray Mackenzie, Virgin Media O2’s director of fraud. Daisy, has "all the time in the world", and the video's unveiling her character, showed just how positive her work has been. “It’s nearly been an hour!” one exasperated scammer said over the phone. Another fraudster said: “I think your profession is bothering people.” The chatbot replied: “I’m just trying to have a little chat.” Image: O2

"Just words on a piece of paper": Olympian's blunt response to lifetime ban

Olympic cycling medallist Matthew Richardson has responded to the <a href="https://www.oversixty.com.au/travel/travel-trouble/olympian-slapped-with-lifetime-ban-after-defection" target="_blank" rel="noopener">lifetime ban</a> he received as "just words on a piece of paper" that "don't carry much weight for me" following his defection to ride for Great Britain. The 25-year-old Olympian received a lot of backlash after his post-Paris defection where he won three medals for Australia despite knowing that he was going to switch to represent his country of birth. While Richardson was proud of his decision, he did express a bit of "shock" at the ban. "I didn't know it was coming," Richardson said during a UCI Track Champions League press conference. "I found it quite interesting. I guess they were just keen to get one last, final blow, one last, final word. "But ultimately, I had left three months ago. I'm not sure where the confusion ... has come from, but I thought it was pretty obvious that, by wanting to ride for GB for the rest of my career, that would mean I didn't want to ride for Australia for the rest of my career. It's almost like you leave your job, and three months later, they go, 'Well, you're fired!'. "It's just words on a piece of paper, really, and they don't really carry much weight for me." In a statement on Monday, AusCycling said that it had investigated the prospect of a two-year non-compete clause being enforced, but discovered it was "legally unenforceable". "The UCI can't enforce regulations on me that I haven't signed for," Richardson said. "That was just words on a piece of paper that, again, don't hold any weight. "As they also said in that review, they're going to have to go back and have a look at that clause, which basically just admits that they're going to have to change it or get rid of it, or whatever, because it clearly has no meaning." Richardson was born in Maidstone, Kent but moved to Perth at the age of nine. He took up cycling with Perth's Midland Cycling Club and not long after was riding with Western Australian Institute of Sport (WAIS). Richardson brushed aside claims that he had threatened AusCycling’s intellectual property by asking to take his bike with him after the Paris Olympics, and said he'd "always been respectful to AusCycling" as well as "thankful for everything" the organisation had done for him. "I really did think I repaid them with all the results, you know — the world championship, the three Olympic medals that I returned," Richardson added. "Unfortunately, noise was created around the issue, but I sleep well at night knowing that noise didn't come from myself. "Hopefully in the years to come, myself and AusCycling can come to some sort of understanding. "But for now, there we go. They've had their final word. "Hopefully we can just put it to bed and just enjoy riding in circles." Images: Instagram

Australian Word of the Year announced

Cost-of-living pressures and anger at the nation-wide supermarket duopoly have influenced the Australian Word of the Year for 2024. The Australian National Dictionary Centre, based at the Australian National University, has chosen "Colesworth": a blended word referencing the country's largest supermarket chains, Coles and Woolworths. Senior Researcher Mark Gwynn said the word is almost exclusively used in negative contexts, with many calling out the power held by both supermarket giants. Although the word itself has been circulated for several years, its use has skyrocketed over the past 12 months, according to Gwynn. "Aussies walk out of the supermarket with less after paying more, but then hear news of massive profits in the supermarket sector. And with official investigations into some of the pricing practices at Australia's two largest supermarkets, it's no wonder that ordinary shoppers have become cynical," he said. "The blend of the supermarket names Coles and Woolworths into Colesworth provides a succinct way of referring to both supermarkets while at the same time hinting at the negative aspects of what is perceived as an unfair duopoly." Other shortlisted words include a mix of terms referencing politics, tax, and climate change. "Breaking" also made the shortlist, following the iconic performance by Australian artist RayGun at the Paris Olympic Games, with words included "climate trigger," "ute tax," and "YIMBY" (Yes In My Backyard).

Prince Philip's final phone call to King Charles revealed

Prince Philip was known for his quick wit and sense of humour, and now his family have shared their favourite moments with him in the BBC documentary Prince Philip: The Family Remembers. In the documentary, King Charles revealed the cheeky remarks the Duke made in their final phone call just hours before his passing on April 9, 2021 at the age of 99. Charles recalled discussing the Duke's upcoming 100th birthday celebrations and having to raise his voice so his father could hear him better, saying: “We’re talking about your birthday! And whether there’s going to be a reception!” The Duke quipped: “Well, I’ve got to be alive for it, haven’t I?” King Charles fondly shared what he said to his father's cheeky remark, “I told him ‘I knew you’d say that!'”. In another part of the documentary, the monarch recalled the benefits of having young parents. “He was marvellous at arranging silly games. I mean, the fun of having obviously young parents was… there were lots of chasing around and mad things," he said. Prince William also shared some of his fond memories with his late grandfather, recalling the pranks they used to pull together, and one of them being squirting mustard all over the ceiling - much to the Queen’s annoyance. “He used to take the lid off [the tube] and put it in your hands … and then he’d squish your hands together to fire the mustard onto the ceiling," William said. “He used to get in a lot of trouble from my grandmother,” he added. William’s cousins, Princess Anne’s children Zara Tindall and Peter Phillips, also remembered the same prank. “He gets you to hold it in your hands and I can’t remember exactly what he says — but he ends up slamming your hands together… it goes all over the ceiling,” Zara said. Her brother Peter added: “I actually think the marks are still there.” Image: Canadian Press/ Shutterstock Editorial

Hospice nurse reveals people's last words before they die

A hospice nurse has revealed the number one thing people say in their final moments before they die. Healthcare expert Julie McFadden, who makes online videos discussing death to help break the taboo around dying, has shared the three most common regrets patients share on their death beds. Speaking to NHS surgeon Dr Karan Rajan on his podcast, Julie said these final discussions tend to centre around what they've taken for granted. "The first one I hear all the time is that they regret not appreciating their health while they had it," Ms McFadden said, reflecting on her 15 years of working in the health sector. "That's the number one thing people say to me, I wish I would have understood how amazing it is to have a working body." The second regret she often hears is people admitting they "worked too much" and wish they hadn't worked their life away, and rather spent time doing things that brought them joy. Finally, she revealed in the clip shared to Instagram, that many dying patients have regrets about relationships. The nurse explained people either wish they had maintained certain relationships and friendships, or regret holding grudges. Dr Rajan responded to Ms McFadden's insight with a story of a young patient that made him realise we are not 'immortal' and we should not take our life "for granted". In the clip shared with his 1.5million followers he said, "A few years ago when I saw a young woman come in with pancreatitis in her 20s, within three hours this young woman is in the intensive care unit, she's intubated, ventilated, and the next day, she had passed away." "That just made me think wow, I'm in my 30s now, I'm 34, life can just go in a flash. So yes, truly don't take it for granted, we sometimes have this tendency to walk around like we're immortal."

Bondi Junction attack victim's family reveals final phone call

Heartbreaking details have emerged of the final video call hero security guard Faraz Tahir made hours before the tragedy. Tahir, was one of six victims killed during the Bondi Junction stabbing attack on April 13, and the only male victim to die in the attacks as he confronted knifeman Joel Cauchi. His loved ones have shared details of the final video call he made before going to work on that tragic day, ahead of a coronial inquest into the massacre beginning on Tuesday. Tahir's family said he was very excited to be starting his new life in a country he described as safe and "very peaceful". "That day ... he was talking to the whole family on a video call in Pakistan, and he was dressed up, and he told us that he was preparing to go to a job," the family told Seven News. "He said it's my first shift in Bondi Junction ... and he was really excited. "He finally felt safe in Australia … he said 'Australia is very beautiful, Australia is very exciting and very peaceful.'" Tahir and colleague Muhammad Taha ran to help when they heard people screaming and shouting. His family said they were proud of the courage Tahir showed during the horrific event. "He was serving as a security guard, and he went above and beyond ... we definitely consider him a hero," they told Seven News. “He did what he was meant to do to protect humanity." “And his sacrifice will make things better in future... to prevent these sorts of incidents happening again.” The inquest is set to go over evidence and hear from a handful of witnesses, which the family said will bring back painful memories. “It is an emotional time... to be going through it again,” they said. "The memories will come back." Images: 7News

"I thought I was Bear Grylls": Woman speaks out after being trapped upside-down for 7 hours

A young woman who spent hours stuck upside-down between two boulders has spoken out about her horrific <a href="https://oversixty.com.au/travel/travel-trouble/woman-rescued-after-getting-stuck-in-between-two-boulders" target="_blank" rel="noopener">ordeal</a> as she was reunited with her rescuers. Matilda Campbell, a 23-year-old from Newcastle, was on a trip away with friends in Laguna, about a 30-minute drive from Cessnock, when she dropped her phone between two huge rocks. The young woman climbed down to retrieve her phone, and when she got stuck upside-down, her friends called 000 for help. Paramedics had to move the boulders using a specialist winch to reach Matilda, before facing the tricky task of “navigating” her out from her precarious position. After suffering minor injuries from the ordeal, Matilda has spoken out about how she ended up in the sticky situation. “We wanted to see nature ... and we saw these beautiful rocks so we sat there ... and then my friend had my phone and it slipped off the rock,” she told 7News. <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/DBsj-x1CYI2/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/DBsj-x1CYI2/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by 7NEWS Sydney (@7newssyd)</a> </div> </blockquote> “And I thought oh no I’m still paying off that phone I need it ... so I ventured down and thought I was Bear Grylls ... and I slipped head first into the crevice where I was stuck for seven hours." “I didn’t freak out at the start ... it took me about half an hour to realise I was fully stuck and then I started to have a big cry." “I’m very thankful I was with my friends, otherwise it would have been a very different story.” Campbell has since been reunited with her rescuers, to whom she says she owes her life, as she said, “I’m just thankful to see them again ...

So, I’m really thankful.” Specialist rescue paramedic Peter Watts said the rescue was “challenging but incredibly rewarding”, saying after the rescue, “In my 10 years as a rescue paramedic, I had never encountered a job quite like this.” In total, the woman spent seven hours hanging upside-down before she was freed, with only minor scratches and bruises but still without her phone, which could not be retrieved.

Freddy Krueger at 40 – the ultimate horror movie monster (and Halloween costume)

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/adam-daniel-301018">Adam Daniel</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> Movie monsters have captivated audiences since the days of early cinema. They evoke fascination and terror, allowing audiences to confront their fears from the safety of the movie theatre or living room. Arguably one of the most enduring and captivating of these monsters is Freddy Krueger, the villain of the <a href="https://www.imdb.com/title/tt0087800/">A Nightmare on Elm Street</a> series who celebrates his 40th screen birthday this November. Memorably played by Robert Englund, Freddy quickly became a cultural icon of the 1980s and 1990s. Beyond his burned face and iconic bladed glove, Freddy’s dark humour and acidic personality set him apart from other silent, faceless killers of the era, such as Michael Myers in <a href="https://www.imdb.com/title/tt0077651/?ref_=nv_sr_srsg_2_tt_6_nm_0_in_0_q_halloween">Halloween</a> or Jason Vorhees in <a href="https://www.imdb.com/title/tt0080761/?ref_=fn_al_tt_1">Friday the 13th</a>. Written and directed by horror maven <a href="https://theconversation.com/wes-craven-the-scream-of-our-times-46915">Wes Craven</a>, 1984’s A Nightmare on Elm Street garnered positive reviews for its innovative concept: Freddy stalked and attacked his victims in their dreams, making him inescapable and allowing him to tap into their deepest fears. The series (seven films plus a 2010 remake and <a href="https://www.imdb.com/title/tt0329101/?ref_=fn_al_tt_1">Freddy vs. Jason</a> spin offs) blended supernatural horror and surrealism with a dark and twisted sense of humour. <h2>Scary … but funny</h2> Humour was key to Freddy’s “popularity”. Both sinister and strangely charismatic, Freddy’s psychological torture of his adolescent victims often oscillated between terrifying and amusing. A famous kill scene from 1987’s <a href="https://www.imdb.com/title/tt0093629/?ref_=fn_al_tt_1">A Nightmare on Elm Street 3: Dream Warriors</a> demonstrates this paradox. Aspiring actress Jennifer drifts off to sleep while watching a talk show on TV. In her dream, the host of the talk show suddenly transforms into Freddy, who attacks his guest before the TV blinks out. When Jennifer timidly approaches the TV set, Freddy’s head and clawed hands emerge from the device, snatching her while delivering an iconic one-liner: “This is it, Jennifer – your big break in TV!” Freddy turns his victims’ fears or aspirations – their dreams – against them. <figure><iframe src="https://www.youtube.com/embed/dCVh4lBfW-c?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>‘Whatever you do, don’t fall asleep.’</figcaption></figure> <h2>Creating a monster</h2> Craven has shared how the character of Krueger came to life in <a href="https://www.imdb.com/title/tt1510985/?ref_=fn_al_tt_1">Never Sleep Again: The Elm Street Legacy</a>, an oral history of the series. He described a childhood experience of seeing a strange mumbling man walking past his childhood home. The man stopped, he said, and looked directly at him “with a sick sense of malice”. This deeply unsettling experience helped shape Freddy’s menacing presence. The character’s creation also emerged from the filmmaker’s interest in <a href="https://www.iflscience.com/nightmare-on-elm-street-was-inspired-by-a-real-life-medical-mystery-60527">numerous reports of Southeast Asian refugees dying in their sleep</a> after experiencing vivid nightmares. In the film, Krueger’s origin story reveals him as a child murderer who was apprehended but released due to a technicality in his arrest. Seeking justice, the parents of his victims take matters into their own hands, and form a vigilante mob. They corner him in his boiler room and burn him alive. But Freddy’s spirit survives to haunt and kill the children of his executioners. <h2>Cultural repression, expressed on film</h2> Film critic and essayist <a href="https://www.cineaste.com/summer2019/robin-wood-on-horror-film-collected-essays-and-reviews#:%7E:text=Freudian%20theory%2C%20a%20crucial%20theoretical,the%20horror%20film%20perpetually%20enacts.">Robin Wood argued</a> horror films often bring to the surface elements society has repressed. These fears, desires, or cultural taboos are not openly acknowledged. But movie monsters act as manifestations of what society suppresses, such as sexuality, violence or deviant behaviour. American academic <a href="https://www.tandfonline.com/doi/abs/10.1080/01956051.1995.9943696">Gary Heba</a> argues Freddy is: <blockquote> an example of America’s political unconscious violently unleashed upon itself, manifesting everything that is unspeakable and repressed in the master narrative (perversion, child abuse and murder, vigilantism, the breakdown of rationality, order, and the family, among others), but still always present in the collective unconscious of the dominant culture. </blockquote> <figure><iframe src="https://www.youtube.com/embed/UBrl4H0Uzng?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Actor Robert Englund calls Freddy Krueger ‘the gift that keeps on giving’.</figcaption></figure> <h2>The monster decades</h2> The 1970s and 1980s marked a golden era for the creation of horror film nasties like Krueger, Myers, <a href="https://www.imdb.com/title/tt0072271/?ref_=fn_al_tt_3">The Texas Chainsaw Massacre</a>’s Leatherface and <a href="https://www.imdb.com/title/tt0094862/?ref_=fn_al_tt_19">killer doll Chucky</a>. Since then, the landscape of horror has shifted, with fewer singular monsters emerging. The diversification of horror sub-genres (zombie virus horror, anyone?), the rise of psychological horror (<a href="https://www.imdb.com/title/tt7784604/?ref_=nv_sr_srsg_2_tt_4_nm_2_in_0_q_heredi">Hereditary</a>), and an emphasis on human-driven terror (<a href="https://www.imdb.com/title/tt0416315/?ref_=nv_sr_srsg_1_tt_7_nm_0_in_0_q_wolf%2520creek">Wolf Creek</a>) or supernatural forces all contribute to this shift. While modern horror continues to thrive, few characters have achieved the same iconic status as Freddy – although some would argue Art the Clown from the recent <a href="https://www.imdb.com/title/tt4281724/">Terrifier</a> franchise and the reinvigorated Pennywise from <a href="https://www.imdb.com/title/tt1396484/?ref_=nv_sr_srsg_1_tt_6_nm_1_in_0_q_it">IT</a> could join this exclusive group. <figure><iframe src="https://www.youtube.com/embed/ZuYoEtEI_go?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>‘Five, six, grab your crucifix.’ A 2010 Nightmare on Elm St reboot failed to fire.</figcaption></figure> <h2>Happy Halloween!</h2> Despite a <a href="https://www.imdb.com/title/tt1179056/">failed reboot in 2010</a>, the legacy of A Nightmare on Elm Street is strong, having influenced numerous filmmakers with its skilful mix of surrealism and slasher horror. However, it’s the orchestrator of the titular nightmares whose legacy is perhaps the strongest. With each Halloween, new fans choose Freddy for their costume. All it takes is a tattered striped sweater, a brown fedora hat, and a glove with sharp, finger-lengthening blades. Don’t forget makeup to re-create Krueger’s grisly facial burns.

"Absolute honour": Federer's stirring words as Nadal hangs up his racquet

Roger Federer and Novak Djokovic have led a wave of tributes after Rafael Nadal announced he would be retiring from playing professional tennis. Nadal announced the news in an emotional Instagram video, where he thanked his family, team, friends and loyal fans for their support, while announcing that the David Cup Finals in November would be his last competition.

Your tenacity, dedication, fighting spirit is going to be taught for decades. Your legacy will live forever." “Only you know what you had to endure to become an icon of tennis and sport in general. Thank you for pushing me to the limit so many times in our rivalry.” Image credits: Daniel Irungu/EPA-EFE/Shutterstock Editorial

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.

Matthew Perry’s chilling final words revealed

Matthew Perry's chilling final words to his assistant on the day of his death has been made public for the first time, not long after five people were <a href="https://www.oversixty.com.au/finance/legal/five-people-arrested-over-matthew-perry-s-death" target="_blank" rel="noopener">arrested</a> in connection to his death. New details about the star's final weeks alive have been released in relation to the plea deal taken by Perry’s former live-in assistant, Kenneth Iwamasa, 59. The former Friends star told his assistant to “shoot me up with a big one,” before he was found dead in the hot tub of his Los Angeles mansion. According to court documents, Perry was injected with a shot of ketamine at around 8.30am, and was administered the second dose while watching a movie at 12.45pm. About 40 minutes later, he asked his assistant to prepare the jacuzzi and shoot him up with the third, and final “big one”, of the day. “Defendant left the residence to run errands... after returning to the residence, defendant found [Mr Perry] face down in the jacuzzi and deceased,” the court documents reportedly said. The newly released police documents also said that Perry had been found unconscious at his home twice before his tragic death in October. Around two weeks before his death it was reported that the doctor accused of supplying the ketamine, Dr Salvador Plascencia, injected him "with a large dose of ketamine", that caused a "significant spike" to his systolic blood pressure and caused his body to "freeze up such that he could not talk or move". Dr Plascencia allegedly told Iwamasa "Let's not do that again" following the scare and later allegedly described Perry as "too far gone and spiralling in his addiction". Despite this the doctor allegedly ordered 10 vials of ketamine for Perry four days before his death, and allegedly contacted Perry's assistant to offer the up for sale. Three other people have been arrested alongside Iwamasa and Dr Plascencia, including Eric Fleming, Dr. Mark Chavez and the so-called “Ketamine Queen of Los Angeles”, Jasveen Sangha. According to Page Six, Iwamasa, Fleming and Chavez all agreed to a deal that saw them plead guilty – while Sangha and Plasencia have pleaded not guilty.

"Words matter": Why Australia's threat level was just raised to "probable"

Anthony Albanese has announced that Australia's terror level has been raised in the wake of spy agency warnings. The Prime Minister announced the change from “possible to probable” on Monday morning at a press conference in Canberra with ASIO director-general Mike Burgess. “ASIO is raising the national terrorist and threat level from possible to probable," Mr Burgess said. “Our decision reflects that the security environment is degrading. A threat level of probable is reassessed as a greater than 50 per cent chance of attack planning in the next 12 months." “It does not mean that we have intelligence about the current attack planning or expectation of an imminent attack." The National Terrorism Threat Advisory System has a scale of five levels, beginning with Not Expected, Possible, Probable, before rising to Expected and Certain. Mr Burgess said the decision was not taken easily, as he explained, “Our decision is not a direct response to the tragic events in the Middle East. At this stage we do not believe any of the terrorist plots we have investigated in the last year have been inspired by Gaza." “Terrorist leaders offshore are not inspiring attacks onshore. This is why we did not raise the threat level in the immediate aftermath of 7 October.” Mr Albanese said the decision follows a cabinet meeting today and briefings by spy agencies. “My government’s first priority is the safety and security of Australians and this morning, I convened a national-security committee meeting to hear from the director-general," Mr Albanese said. “I want to reassure Australians that probable does not mean inevitable and it does not mean it is intelligence about an imminent threat or danger. But the advice that we have received is that more Australians are embracing a more diverse range of extreme ideologies and it is our responsibility to be vigilant. Mr Burgess said it did not mean there was any imminent threat of a terrorist attack in Australia, but said it was about being vigilant and prepared. “Australia’s security environment is more volatile and more unpredictable, you’ve heard me say many times of espionage and foreign interference, our principal security concerns,’’ he said. “While the threats to our way of life are elevated we are seeing an increase in extremism, more Australians are being radicalised and radicalised more quickly. More Australians are embracing a more diverse range of extreme ideologies and more Australians are willing to use violence to advance their cause." In response to a question from the media on the Greens, who recently accused the Labor Party of being implicit in genocide when it comes to the war in Palestine, the Prime Minister said some of the rhetoric was of concern. “Words matter and it is important that people engage in a way that is respectful, that people don’t make claims that they know are not right in order to try to secure some short-term political advantage,’’ he said. Concluding the press conference, Mr Burgess said it is up to every Australian to say vigilant and report any suspicious behaviour. He said, "This is a matter for everyone, community leaders, politicians, the media, watch your words, watch your actions. Be very careful about that because there is a direct correlation between inflamed language and inflamed tension and violence.” Image credits: LUKAS COCH/EPA-EFE/Shutterstock Editorial

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

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> 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. Now social media has blue light from our devices in its sights. So can scrolling on our phones really damage your skin? And will applying creams or lotions help? Here’s what the evidence says and what we should really be focusing on. <h2>Remind me, what actually is blue light?</h2> 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. 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>. Now, we’re learning more about the impact of blue light on our skin. <h2>How does blue light affect the skin?</h2> The evidence for blue light’s impact on skin is still emerging. But there are some interesting findings. 1. Blue light can increase pigmentation <a href="https://academic.oup.com/ced/article-abstract/46/5/934/6598472?redirectedFrom=fulltext&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. 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. 2. Blue light can give you wrinkles 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. 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. 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. 3. Blue light can disrupt your sleep, affecting your skin 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. 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. 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>. 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. 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. 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. <h2>Can skincare protect me?</h2> The beauty industry has capitalised on concerns about blue light and offers a range of protective products such as mists, serums and lip glosses. 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. 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. 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. <h2>What can I do to minimise blue light then?</h2> Here are some simple steps you can take to minimise your exposure to blue light, especially at night when it can disrupt your sleep: <ul> <li> 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 </li> <li> 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 </li> <li> hold your phone or device away from your skin to minimise exposure to blue light </li> <li> use sunscreen. Mineral and physical sunscreens containing titanium dioxide and iron oxides offer broad protection, including from blue light. </li> </ul> <h2>In a nutshell</h2> Blue light exposure has been linked with some skin concerns, particularly pigmentation for people with darker skin. However, research is ongoing. While skincare to protect against blue light shows promise, more testing is needed to determine if it works. 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" /> <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> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Optus giving away 20,000 free phones to vulnerable customers

Optus will be giving away 20,000 mobile phones to vulnerable customers ahead of the 3G network shut down. Following the footsteps of Telstra, who gave out <a href="https://www.oversixty.com.au/finance/money-banking/telstra-giving-free-phones-to-elderly-and-remote" target="_blank" rel="noopener">12,000 mobile phones</a> to their most vulnerable remote and elderly customers last month, Optus will offer thousands of free mobile phones to customers enduring financial hardship and vulnerable customers finding it difficult to replace their current phones. “We know that many impacted customers are actually using a 4G handset that reverts to 3G for calls, so it’s vital these customers understand the importance of upgrading their handsets when notified,” Optus’ head of new products Harvey Wright said. Messages have been sent to eligible customers, and the telco giant has also rolled out special deals encouraging Australian's to upgrade. The move to switch off 3G means that soon certain mobile devices will no longer be able to send texts, make calls, or contact triple-0 in an emergency. A few older 4G handsets will also be affected. Telstra will turn off their 3G network on August 31, while Optus will turn it off on September 1. TPG Telecom and Vodafone have already turned it off. Australia's mobile network operators say that the move will help boost the capacity, speed and reliability of the newer 4G and 5G networks. The Australian Mobile Telecommunications Association (AMTA) have also urged customers to take action to ensure that they stay connected. “Whether it’s your day-to-day mobile or one you keep in the drawer for an emergency, we encourage you to check all of your devices to ensure they will be supported once Australia’s 3G networks are switched off,” AMTA chief executive Louise Hyland said. The AMTA suggests that concerned customers should visit their <a href="https://amta.org.au/3g-closure/" target="_blank" rel="noopener">website</a> to find out if their devices will be supported. “It is important to note that while 3G networks are still in operation, those affected mobile devices will continue to connect to any available 3G network while in coverage, to make emergency calls to triple-0,” Hyland said. “However, once the 3G networks are fully closed, these phones will not be able to make emergency calls. “It is crucial to act now if you know you have an older mobile device and you haven’t already upgraded.” Image: Shutterstock

Why you should be wary of charging your phone in an airport

While charging stations at airports can often be life-savings before boarding a flight, it turns out these handy outlets can be leaving you vulnerable. Many people have fought over a spot to charge up your devices at the last minute before embarking on a holiday, but next time you leave home with your phone or laptop needing some more juice, think again. Emily Stallings, co-founder of tech retailer <a href="https://www.getcasely.com/">Casely</a>, says that by plugging your phone into a power outlet at a public USB charging station, you're at risk of data breaches and malware infection. "If a device gets infected, it could end up leaking sensitive information or even stop working properly," she told <a href="https://travel.nine.com.au/latest/charging-phone-at-the-airport-danger-expert/57d141df-33ba-4a50-89e5-26f6f2a0c18d">9Travel</a>. These public USB ports have often been compromised by cybercriminals, who then use these unsecured ports to steal sensitive information transmitted between devices. "From personal emails to financial data, the information intercepted through these compromised ports could lead to identity theft, financial loss, and other serious consequences," explains Stallings. The best way to get around this threat, without letting your phone run out of battery, is to pack a portable charging device in your carry-on bag every time you travel. With your own cord and power bank, it's far less likely that any sneaky hackers will be able to access your device's data. Stallings says you can also enable security features such as USB Restricted Mode on your device, for those moments when you're desperate for a charger and have to rely on public ports. "This adds an extra layer of protection against potential data breaches and malware infections when charging from public USB ports." "By activating USB Restricted Mode or similar security features, you restrict data transfer over USB connections, effectively preventing unauthorised access to your device's data while charging in public spaces."

Telstra giving free phones to elderly and remote

With the 3G network set to shut down completely on August 31, Telstra announced that it will be giving 12,000 mobile phones away for free in a bid to help the most vulnerable customers switch to 4G. Starting from Tuesday, the telecommunications company will be issuing complimentary phones to customers who are elderly, live rurally or are facing difficult situations. These include those facing financial issues, recovering from natural disasters, or those who have a life-threatening medical condition and therefore rely on a working phone. Telstra have also identified those who live regionally or are over 80 years old and may require extra transition support, as they may have difficulty accessing a physical store to make the switch. Those who are flagged as eligible will be contacted by the telco company, and they are encouraging customers who receive the message to follow the instructions given to make the switch. Major Brendan Nottle from The Salvation Army has praised this initiative for helping the "most vulnerable members of our community." “Connection is one of the most important things to maintain in our society, whether it is with friends and family or with housing and support services,” he said. “Ensuring that every Australian, from any background or level of income, can take part in our modern digital society is crucial. “A phone can be a gateway to social inclusion, community connection and support, and with the upcoming closure of 3G networks in Australia it is important for us to reach out and ensure that this can continue for everyone.” Customers who are yet to upgrade are also told to make the switch sooner than later. Other devices that will be affected by the shutdown include certain smart watches, tablets, medical alarms, EFTPOS terminals and security monitors. Images: Shutterstock

The voice in your head may help you recall and process words. But what if you don’t have one?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/derek-arnold-106381">Derek Arnold</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Can you imagine hearing yourself speak? A voice inside your head – perhaps reciting a shopping list or a phone number? What would life be like if you couldn’t? Some people, including me, cannot have imagined visual experiences. We cannot close our eyes and conjure an experience of seeing a loved one’s face, or imagine our lounge room layout – to consider if a new piece of furniture might fit in it. This is called “<a href="https://theconversation.com/a-blind-and-deaf-mind-what-its-like-to-have-no-visual-imagination-or-inner-voice-226134">aphantasia</a>”, from a Greek phrase where the “a” means without, and “phantasia” refers to an image. Colloquially, people like myself are often referred to as having a “blind mind”. While most attention has been given to the inability to have imagined visual sensations, aphantasics can lack other imagined experiences. We might be unable to experience imagined tastes or smells. Some people cannot imagine hearing themselves speak. A <a href="https://www.sciencealert.com/we-used-to-think-everybody-heard-a-voice-inside-their-heads-but-we-were-wrong">recent study</a> has advanced our understanding of people who cannot imagine hearing their own internal monologue. Importantly, the authors have identified some tasks that such people are more likely to find challenging. <h2>What the study found</h2> Researchers at the University of Copenhagen in Denmark and at the University of Wisconsin-Madison in the United States <a href="https://journals.sagepub.com/doi/10.1177/09567976241243004">recruited 93 volunteers</a>. They included 46 adults who reported low levels of inner speech and 47 who reported high levels. Both groups were given challenging tasks: judging if the names of objects they had seen would rhyme and recalling words. The group without an inner monologue performed worse. But differences disappeared when everyone could say words aloud. Importantly, people who reported less inner speech were not worse at all tasks. They could recall similar numbers of words when the words had a different appearance to one another. This negates any suggestion that aphants (people with aphantasia) simply weren’t trying or were less capable. <h2>A welcome validation</h2> The study provides some welcome evidence for the lived experiences of some aphants, who are still often told their experiences are not different, but rather that they cannot describe their imagined experiences. Some people feel anxiety when they realise other people can have imagined experiences that they cannot. These feelings may be deepened when others assert they are merely confused or inarticulate. In my own <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2024.1374349/full">aphantasia research</a> I have often quizzed crowds of people on their capacity to have imagined experiences. Questions about the capacity to have imagined visual or audio sensations tend to be excitedly endorsed by a vast majority, but questions about imagined experiences of taste or smell seem to cause more confusion. Some people are adamant they can do this, including a colleague who says he can imagine what combinations of ingredients will taste like when cooked together. But other responses suggest subtypes of aphantasia may prove to be more common than we realise. The authors of the recent study suggest the inability to imagine hearing yourself speak should be referred to as “anendophasia”, meaning without inner speech. Other authors had suggested <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8551557/">anauralia</a> (meaning without auditory imagery). Still other researchers have referred to all types of imagined sensation as being different types of “imagery”. Having <a href="https://www.sciencedirect.com/science/article/abs/pii/S0010945222000417">consistent names</a> is important. It can help scientists “talk” to one another to compare findings. If different authors use different names, important evidence can be missed. <h2>We have more than 5 senses</h2> Debate continues about how many senses humans have, but some scientists reasonably argue for a <a href="https://www.sensorytrust.org.uk/blog/how-many-senses-do-we-have#:%7E:text=Because%20there%20is%20some%20overlap,sensation%20of%20hunger%20or%20thirst.">number greater than 20</a>. In addition to the five senses of sight, smell, taste, touch and hearing, lesser known senses include thermoception (our sense of heat) and proprioception (awareness of the positions of our body parts). Thanks to proprioception, most of us can close our eyes and touch the tip of our index finger to our nose. Thanks to our vestibular sense, we typically have a good idea of which way is up and can maintain balance. It may be tempting to give a new name to each inability to have a given type of imagined sensation. But this could lead to confusion. Another approach would be to adapt phrases that are already widely used. People who are unable to have imagined sensations commonly refer to ourselves as “aphants”. This could be adapted with a prefix, such as “audio aphant”. Time will tell which approach is adopted by most researchers. <h2>Why we should keep investigating</h2> Regardless of the names we use, the study of multiple types of inability to have an imagined sensation is important. These investigations could reveal the essential processes in human brains that bring about a conscious experience of an imagined sensation. In time, this will not only lead to a better understanding of the diversity of humans, but may help uncover how human brains can create any conscious sensation. This question – how and where our conscious feelings are generated – remains one of the great mysteries of science.<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/230973/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/derek-arnold-106381">Derek Arnold</a>, Professor, School of Psychology, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
