Does too much TikTok, YouTube or Instagram actually rot your brain? Experts weigh in
Doomscrolling. Instagram obsessions. Mindless YouTube video viewing.
Distracting behaviours, yes. But can they actually rot a person's brain?
In 2024, Oxford University Press named 'brain rot' as its word of the year, defining it as the 'supposed deterioration of a person's mental or intellectual state' caused by overconsuming 'trivial or unchallenging' material found on social media and other online platforms.
'It's what happens when you consume too much low-quality online content, which is like junk food for the brain,' says Dr Andreana Benitez, an associate professor in the department of neurology at the Medical University of South Carolina, in the United States.

But whether that content is actually harming the brain – and how – remains unclear.
According to the US Centres for Disease Control and Prevention (CDC), half of teens in the US spend four hours or more looking at screens each day, and global estimates suggest adults may be online an average of more than six hours per day.

Do we really need so much protein? Gym bros say yes, but don't let them scare you
There are a lot of health warnings telling us what we should cut back on, if not outright avoid. Advertisement Fat is terrible for our heart and arteries. Salt will give us high blood pressure. Sugar is even worse, making us diabetic. And let's not forget about ultra-processed foods that are full of chemicals, preservatives and additives. They'll definitely give you cancer and kill you, they say. Is there anything to enjoy guilt-free? A lot of online health experts and diet gurus, as well as muscle-bound gym bros, insist that what we need is more protein. 'The more protein, the better,' they scream in social media videos. Most of them are highly annoying. In their weights room with dumbbells in the background, in a shirt too small for their buff pectorals, they look directly at the camera as they try to scare us. 'If you're like most people, you're just not getting enough protein!' they warn urgently. Proteins are essential for building and repairing muscles, as well as a host of other bodily functions. Photo: SCMP It's the same alarmist tone as the callisthenics exercise advert that constantly invades my middle-aged social media feed. Preying on male vanity, they suggest if I cannot do 50 push-ups in a row, I need to seriously pay attention and sign up now for their easy daily routine to get back in shape.

US brain drain set to gather pace as academics seek posts outside Trump's America
A brain drain hitting American universities is expected to gather pace before the start of the new academic year as funding cuts and attacks on academic freedom have led increasing numbers of academics to question whether they wish to stay in the United States. Advertisement Last month, the historians Timothy Snyder and Marci Shore, who are married to each other, announced their departure from Yale University to join the University of Toronto, citing concerns over the direction of American democracy during Donald Trump's presidency Meanwhile, professors who face funding cuts and uncertain futures have quietly signalled their availability within academic circles—and are now fielding unexpectedly high-paying offers from institutions abroad. David Lesperance, an immigration and tax specialist at the Canadian law firm Lesperance & Associates, said he was helping 'high-profile US tenured professors and top-level researchers' explore relocation options in Canada, Australia and Europe, with many hoping to begin new roles by September. Advertisement 'Many of them work in medical research, AI, physics, and computer science — these are the hot ticket fields right now,' Lesperance said. He said one American client was weighing offers from Britain, Australia and China. 'He's passionate about his research, and the decision will come down to which place offers the best funding, lab support and staffing,' Lesperance said.

Chinese swimmers had to have eaten 5kg of food to fail 2021 drug tests, Usada chief says
The head of the United States Anti-Doping Agency told senators that Chinese swimmers would have had to eat around 11 pounds (5kg) of food to test for the amounts of the performance enhancer that resulted in the much-debated positive drug tests from 2021 that were later disregarded. Advertisement 'It's unbelievable to think that Tinkerbell just showed up and sprinkled it all over the kitchen,' Travis Tygart said in a Senate hearing on Tuesday focused on the World Anti-Doping Agency's response to the doping case. A key part of that case was Wada's acceptance of the explanation from Chinese authorities that the swimmers had been contaminated by traces of the drug trimetazidine (TMZ) in a hotel kitchen. Usada scientists analysed data from a report commissioned by Wada to come up with the amount of food (5kg) or liquid (4.9 litres) the athletes would have had to have consumed to test positive at the levels they did. Wada officials declined to participate in the hearing, which spokesperson James Fitzgerald called 'another political effort led by Travis Tygart … to leverage the Senate and the media in a desperate effort to relitigate the Chinese swimming cases and misinform athletes and other stakeholders'. Advertisement Also testifying was former US drug tsar Rahul Gupta, whose decision at the start of this year to withhold US$3.6 million in funding – the biggest single chunk that Wada receives on an annual basis – furthered a long-running feud between US and Wada authorities.
