Climate shocks threaten $2.3 trillion global sports economy, study warns

Extreme weather threatens annual revenue growth in the $2.3 trillion sports economy, where expansion is driven mainly by tourism tied to resource-depleting global events such as the just-concluded Milano Cortina Games, a report has shown. The sector's growth should be used to maximise social benefits such as reducing public healthcare spending and advancing gender equality. That entails tackling the threat the industry faces from climate change and nature loss - which it risks exacerbating thr...

Caffeinated beverages may help protect the brain, study says

Drinking a few cups of caffeinated coffee or tea every day may help in a small way to preserve brain power and prevent dementia, researchers reported on Monday.

Medical misinformation more likely to fool AI if source appears legitimate, study shows

In tests of 20 open-source and proprietary large language models, the software was more often tricked by mistakes in realistic-looking doctors' discharge notes than by mistakes in social media conversations, researchers reported in The Lancet Digital Health. "Current AI systems can treat confident medi...

AI no better than other methods for patients seeking medical advice, study shows

Asking AI about medical symptoms does not help patients make better decisions about their health than other methods, such as a standard internet search, according to a new study published in Nature Medicine.

Water vapour heats atmosphere more than aerosols over Indo-Gangetic plain: Study

Water vapour plays a far greater role in heating the atmosphere than aerosols, particularly over the densely populated and pollution-prone Indo-Gangetic Plain (IGP), according to a new scientific study that underscores the need to jointly consider both components for accurate climate projections. The research highlights that while aerosols and water vapour together shape the Earth’s radiation balance, water vapour has a stronger influence on atmospheric heating. Their interaction, however, si...

Drinking soda, fruit juices may raise diabetes risk: Study

Love to drink sugar-sweetened beverages like soda, fruit juice, or energy and sports drinks? They may raise your risk of developing type 2 diabetes (T2D), according to a study. However, dietary sugars consumed in or added to nutrient-dense foods, such as whole fruits, dairy products, or whole grains, do not cause metabolic overload in the liver, said researchers from Brigham Young University in the US. These embedded sugars elicit slower blood glucose responses due to accompanying fiber, fats,...
