2 To 3 Cups of Coffee a Day May Reduce Dementia Risk. But Not if It's Decaf.

If you think your daily doses of espresso or Earl Grey sharpen your mind, you just might be right, new science suggests. The New York Times: A large new study provides evidence of cognitive benefits from coffee and tea -- if it's caffeinated and consumed in moderation: two to three cups of coffee or one to two cups of tea daily. People who drank that amount for decades had lower chances of developing dementia than people who drank little or no caffeine, the researchers reported. They followed 131,821 participants for up to 43 years. "This is a very large, rigorous study conducted long term among men and women that shows that drinking two or three cups of coffee per day is associated with reduced risk of dementia," said Aladdin Shadyab, an associate professor of public health and medicine at the University of California, San Diego, who wasn't involved in the study. The findings, published Monday in JAMA, don't prove caffeine causes these beneficial effects, and it's possible other attributes protected caffeine drinkers' brain health. But independent experts said the study adjusted for many other factors, including health conditions, medication, diet, education, socioeconomic status, family history of dementia, body mass index, smoking and mental illness.

Deepfake Fraud Taking Place On an Industrial Scale, Study Finds

Deepfake fraud has gone "industrial," an analysis published by AI experts has said. From a report: Tools to create tailored, even personalised, scams -- leveraging, for example, deepfake videos of Swedish journalists or the president of Cyprus -- are no longer niche, but inexpensive and easy to deploy at scale, said the analysis from the AI Incident Database. It catalogued more than a dozen recent examples of "impersonation for profit," including a deepfake video of Western Australia's premier, Robert Cook, hawking an investment scheme, and deepfake doctors promoting skin creams. These examples are part of a trend in which scammers are using widely available AI tools to perpetuate increasingly targeted heists. Last year, a finance officer at a Singaporean multinational paid out nearly $500,000 to scammers during what he believed was a video call with company leadership. UK consumers are estimated to have lost $12.86bn to fraud in the nine months to November 2025. "Capabilities have suddenly reached that level where fake content can be produced by pretty much anybody," said Simon Mylius, an MIT researcher who works on a project linked to the AI Incident Database. He calculates that "frauds, scams and targeted manipulation" have made up the largest proportion of incidents reported to the database in 11 of the past 12 months. He said: "It's become very accessible to a point where there is really effectively no barrier to entry."

Electric Cars Are Making It Easier To Breathe, Study Finds

An anonymous reader shares a report: It turns out that when fewer cars spew exhaust as they drive along, air quality improves. That's the conclusion of a new study published in The Lancet Planetary Health that looked at the effect of increased numbers of both EVs and plug-in hybrids on air pollution in California. The Golden State has by far the largest number of plug-in vehicles in the United States, and they've now reached significant numbers to have a positive impact on air quality. Between 2019 and 2023, for every 200 EVs or plug-in hybrids added, nitrogen dioxide (NO2) levels dropped 1.1%, according to the study, which used satellite data to track those levels through the unique way NO2 absorbs and reflects sunlight. NO2 can trigger asthma attacks, cause bronchitis, and increase the risk of heart disease and stroke.
