A drug has increased the lifespans of laboratory animals by nearly 25%, in a discovery scientists hope can slow human ageing too. The treated mice were known as “supermodel grannies” in the lab. They were healthier, stronger and developed fewer cancers than their unmedicated peers. The drug is already being tested in people.
“What we found is that even in healthy people who are constipated, there is a rise in these toxins in the bloodstream” […] during diarrhea, the body excretes excessive bile acid, which the liver would otherwise recycle to dissolve and absorb dietary fats. Fiber-fermenting gut bacteria known as “strict anaerobes,” associated with good health thrived in the “Goldilocks zone” of one or two poops a day.
Study reveals how anesthesia drug propofol induces unconsciousness
A single dose of psilocybin, a psychedelic that acutely causes distortions of space–time perception and ego dissolution, produces rapid and persistent therapeutic effects in human clinical trials. […] a single dose (25 mg) demonstrated rapid and sustained symptom relief in depression, addiction, and end-of-life anxiety. The image comes from dozens of brain scans produced by researchers who gave psilocybin to participants […] the red, orange and yellow hues reflecting a significant departure from normal activity patterns. The blues and greens reflect normal brain activity. “Psilocybin, in contrast to any other drug we’ve tested, has this massive effect on the whole brain that was pretty unexpected” […] these findings cannot show exactly what causes the therapeutic benefit of psilocybin, but “it’s possible psilocybin is directly causing” the brain-network changes. That, or it is creating a psychedelic experience that in turn causes parts of the brain to behave differently. [Nature | NY Times | ScienceDaily]
Does Generative AI Facilitate Investor Trading? […] We first document a significant decline in stock trading volume during ChatGPT outages and find that the effect is stronger for firms with corporate news released immediately before or during the outages. We further document similar declines in the short-run price impact, return variance, and bid-ask spreads, consistent with a reduction in informed trading during the outage periods.
Everyone Is Judging AI by These Tests. But Experts Say They’re Close to Meaningless Benchmarks used to rank AI models are several years old, often sourced from amateur websites, and, experts worry, lending automated systems a dubious sense of authority
Want to spot a deepfake? Look for the stars in their eyes. AI-generated fakes can be spotted by analyzing human eyes in the same way that astronomers study pictures of galaxies.
The golden age of scammers: AI-powered phishing — The 5/5 rule says that it takes 5 prompts and just 5 minutes to create a phishing campaign nearly as successful as a phishing campaign generated by IBM engineers. What took technically advanced humans 16 hours, generative AI did in 5 minutes
We examined 200 videos from popular TikTok fitspiration hashtags (fitness, fitspo, gymtok, fittok). […] Videos of men included muscular idealised bodies and objectification through face obscurity (excluding the face from view) more frequently than videos of women. […] 60 % of videos presented incorrect or harmful information
A drug commonly prescribed to thin blood can be repurposed as a cheap antidote to cobra venom […] Snakebites kill about 138,000 people a year. Cobras account for most bites in parts of Africa and India.
