ChatGPT use linked to cognitive decline, research reveals
Relying on the artificial intelligence chatbot ChatGPT to help you write an essay could be linked to cognitive decline, a new study reveals.
Researchers at the Massachusetts Institute of Technology Media Lab studied the impact of ChatGPT on the brain by asking three groups of people to write an essay. One group relied on ChatGPT, one group relied on search engines, and one group had no outside resources at all.
The researchers then monitored their brains using electroencephalography, a method which measures electrical activity.
The team discovered that those who relied on ChatGPT — also known as a large language model — had the 'weakest' brain connectivity and remembered the least about their essays, highlighting potential concerns about cognitive decline in frequent users.
'Over four months, [large language model] users consistently underperformed at neural, linguistic, and behavioral levels,' the study reads. 'These results raise concerns about the long-term educational implications of [large language model] reliance and underscore the need for deeper inquiry into AI's role in learning.'
The study also found that those who didn't use outside resources to write the essays had the 'strongest, most distributed networks.'
While ChatGPT is 'efficient and convenient,' those who use it to write essays aren't 'integrat[ing] any of it' into their memory networks, lead author Nataliya Kosmyna told Time Magazine.
Kosmyna said she's especially concerned about the impacts of ChatGPT on children whose brains are still developing.
'What really motivated me to put it out now before waiting for a full peer review is that I am afraid in 6-8 months, there will be some policymaker who decides, 'let's do GPT kindergarten,'' Kosmyna said. 'I think that would be absolutely bad and detrimental. Developing brains are at the highest risk.'
But others, including President Donald Trump and members of his administration, aren't so worried about the impacts of ChatGPT on developing brains.
Trump signed an executive order in April promoting the integration of AI into American schools.
'To ensure the United States remains a global leader in this technological revolution, we must provide our Nation's youth with opportunities to cultivate the skills and understanding necessary to use and create the next generation of AI technology,' the order reads. 'By fostering AI competency, we will equip our students with the foundational knowledge and skills necessary to adapt to and thrive in an increasingly digital society.'
Kosmyna said her team is now working on another study comparing the brain activity of software engineers and programmers who use AI with those who don't.
'The results are even worse,' she told Time Magazine.

Walmart recalls item they warn to 'dispose of immediately' after reports of burn injuries
Walmart has recalled a range of electric blankets after reports they have caught fire and caused serious burns. The grocery giant has been forced to recalled the MaxKare Electric Blankets after the Consumer Product Safety Commission (CPSC) received reports from consumers that the blankets had overheated, caught fire and caused serious burn injuries. The blankets, available in brown and gray, were sold exclusively online by Walmart between June 2021 and November 2024. They came in twin, full, queen sizes costing between $27 to $80. The roughly 8,500 items effected by the recall notice will bear the model numbers HB18A-7284-1, HB18A-8490-2 or HB18A-6284-1 which can be found on the blanket's label. The retailer has urged anyone who bought the effected products to dispose of them immediately. Those that wish to seek refunds can contact the blanket's manufacturer Shenzhen Yumo Commerce. 'Walmart and Sam's Club are committed to the health and safety of our customers and members and to providing products that are safe and compliant, all supported by our health and wellness, product safety, and food safety professionals,' the retailer said in a statement regarding the latest recall. 'In the event of a product recall, we work swiftly to block the item from being sold and remove it from our stores and clubs.' It comes as federal officials announced they have launched an investigation into the deaths of three people and a pregnancy loss connected to ready meals sold at retail giants Walmart and Kroger. Food distributor FreshRealm announced earlier this week that it would be recalling its chicken fettuccine alfredo products over listeria concerns. The US Food Safety and Inspection Service (FSIS) is now investigating the outbreak, which has sickened 17 people in 13 states. The affected products include 32.8oz and 12.3oz trays of Marketside Grilled Chicken Alfredo with Fettucine pasta with best-by dates of June 26 and 27, 2025. Also included in the recall is 12.5oz trays of Home Chef Heat & Eat Chicken Fettucine Alfredo pasta with a best-by date of June 19,2025 or before. The meals are sold nationwide at Walmart, under the Marketside brand, and Kroger, under the Home Chef brand. A listeria infection usually causes fever, headache and diarrhea in most people, but it can be deadly for pregnant women, newborns, the elderly and those with weak immune systems. Federal officials launched an investigation into the deaths of three people and a pregnancy loss connected to ready meals sold at Walmart Earlier this year Walmart was forced to recall its Marketside celery sticks from stores in 29 states over possible listeria contamination. The issue was discovered during a random sampling by the Georgia Department of Agriculture. A month later Walmart was also embroiled in another mass recall of canned tuna over a potentially fatal food poisoning risk. Tri-Union Seafoods announced the recall after its supplier informed the company that the cans' 'easy open' pull tab lids have a manufacturing defect.

'MAGA Mark' Zuckerberg leaves Meta staff horrified after Joe Rogan chat
Meta CEO Mark Zuckerberg 's new machismo and perceived alignment with President Trump has reportedly unsettled employees and execs inside the company. The billionaire tech mogul has been dubbed 'MAGA Mark' by staffers following his January appearance on The Joe Rogan Experience, where he criticized Corporate America as 'culturally neutered' and called for more 'masculine energy' in the workplace. Zuckerberg's remarks - made as an aspiring MMA fighter - sparked discomfort among employees at Meta, the parent company of Facebook and Instagram, according to the Financial Times. In the days following the interview, several executives raised concerns during a leadership meeting at Meta's California headquarters. 'He basically said, "If you don't like it, tough s**t,"' a source familiar with the conversation told the Financial Times. On the podcast, Zuckerberg, 41, also praised mixed martial arts as a form of male bonding and argued that male aggression can be constructive. 'There's this crazy thing about wrestling,' he told Rogan, a former MMA commentator. 'If you get into a fight with someone at work, you're probably going to get fired. But if you train in MMA, you can roll hard with someone and you're both better friends afterward.' 'In a lot of the corporate world, there's this assumption that aggression or intensity is inherently negative,' he added. 'But it's not. I actually think it's useful - you just need to know how to channel that energy.' Zuckerberg's evolution from a traditional Silicon Valley liberal to someone increasingly aligned with Donald Trump, 79, has become a hallmark of his leadership at Meta. Once known as a low-profile, hoodie-clad Democrat, Zuckerberg has reshaped his public persona - appearing shirtless in MMA training videos, sporting gold chains, and flaunting luxury watches. His appearance on Joe Rogan's podcast - one of several engagements with largely male, anti-woke audiences - fueled growing criticism that he's signaling a broader political shift to the right. His public praise for Trump and reductions in content moderation at Meta have further intensified concerns about the company's ideological direction, the Financial Times reported. But, insiders argue that Zuckerberg isn't changing so much as revealing a version of himself they've always known. 'When he was 19 years old, I think he had an idea in his head of what a CEO was supposed to be like and he was trying to be that, especially in public,' Meta's chief technology officer Andrew Bosworth, told the Financial Times. 'The public is seeing him more how we have, internally, since the beginning,' Bosworth added. Zuckerberg's evolving persona comes as he positions Meta aggressively in the high-stakes race for dominance in artificial intelligence. Last week, the company made headlines with its $14.3 billion acquisition of Scale AI, securing a 49 percent non-voting stake in the startup and access to its infrastructure and talent - including founder Alexandr Wang, who now leads Meta's new 'superintelligence' unit. However, his move has triggered backlash from rivals, with OpenAI and Google severing ties with Scale over conflict-of-interest concerns, the New York Post reported. With plans to spend $65 billion annually on AI by 2025, the technology company is 'betting big.' But, the ambitious approach comes with risks, including mounting costs, regulatory scrutiny, and challenges in retaining top engineering talent. As of Friday, Zuckerberg was the world's second-richest person, with a net worth of $245 billion, according to the Bloomberg Billionaires Index. Despite the heavy-hitting criticism, Zuckerberg isn't alone in his apparent shift toward a more MAGA- aligned stance. Amazon founder Jeff Bezos, once seen as a liberal-leaning titan of industry, has recently voiced criticisms of the Biden administration and echoed right-leaning talking points. Tesla and SpaceX CEO Elon Musk famously made a similar pivot earlier, aligning himself with conservative narratives on free speech, 'wokeness,' and government overreach - positions that initially found common ground with figures like Trump before their public falling out.

Creative industries to get £380m boost ahead of industrial strategy launch
Britain's film, music and video game industries are set to receive millions of pounds of investment as the Government seeks to ensure the UK's place as a creative superpower. The investment, announced by Culture Secretary Lisa Nandy, will see £380 million spent on a range of projects intended to double private investment in the creative industries. Ms Nandy said the investment would 'boost regional growth, stimulate private investment, and create thousands more high-quality jobs'. The figure includes £25 million for research into cutting-edge technologies such as the virtual avatars used in Abba Voyage, and £75 million to support the film industry. It will also see £30 million put towards backing start-up video games companies – an industry worth billions of pounds to the UK – and another £30 million for the music industry, including an increase in funding for grassroots venues. Another £150 million will be split between the mayors of Manchester, Liverpool, the West Midlands, West Yorkshire, the North East and the West of England to support creative businesses in their regions. The announcement comes as the Government prepares to publish its industrial strategy next week, billed as a 10-year, multibillion-pound plan to back certain sectors and secure growth for the UK economy. The creative industries are set to be one of the winners, with a plan for the sector expected to be published alongside the wider industrial strategy. Business Secretary Jonathan Reynolds said: 'The UK's creative industries are world-leading and have a huge cultural impact globally, which is why we're championing them at home and abroad as a key growth sector in our modern industrial strategy.' But earlier this month, the Government also rejected a planning application for a major new film studio near Holyport, in Berkshire, over its impact on the green belt. The £380 million has been welcomed by the industry, with the Broadcasting, Entertainment, Communications and Theatre Union (Bectu) saying it was a 'show of commitment to the sector'. But Bectu chief Philippa Childs said creative workers would also be looking for 'sustained support' from the Government as the sector 'recovers from a series of external shocks'. Recent years have seen the sector rocked by Covid, the cost-of-living crisis and concerns about the impact of AI and Donald Trump's threat to impose tariffs on films made outside the US. Conservative shadow culture secretary Stuart Andrew accused Labour of threatening the 'very survival' of the creative industries. He said: 'From their national insurance jobs tax to their business rates hike, Labour are pushing creative businesses to the brink, and we now know that Rachel Reeves has a secret plan to raise taxes – meaning things will only get worse. 'Labour must recognise that their economic mismanagement is dealing a devasting blow to the sector.'
