A few years' back, a viral trend overtook social media that nobody saw coming: ShantyTok .

Biohacker Bryan Johnson recently bragged about his girlfriend's "top 1%" vagina as the at-home vaginal microbiome test industry is thriving. Farrah was fed up with her vagina . For the past two years, the 29-year-old dancer from Ohio had been dealing with severe pelvic pain and vaginal odor. "It was like 8/10, horrible core pain," she says. When she visited doctors, she told them what she thought the culprit was: an allergic reaction to soy oil in a vat of water she'd swam in during a pirate-themed dinner theater performance. But they didn't believe her.

Colloquially, OCD is known as the doubting disorder. In his new book, Simone Stolzoff explores whether treating that uncertainty with magic mushrooms can help people through it. Adam Strauss is standing in his New York City apartment, holding the limp cord of his headphones, trying to choose between the two MP3 players on his desk: the iPod and the iRiver, its Korean counterpart. He tries different songs, different genres, different instruments. The iRiver tends to sound better overall, but the iPod offers a little more nuance in the midrange. The iPod has a better battery life, but the iRiver still lasts eight hours-- longer than he's ever continuously listened to music. Then again, he's never owned an MP3 player. He goes back and forth, back and forth, testing vocal ranges, button resistance, interface aesthetics. It would be one thing if it were just Adam's decision of which MP3 player to buy. After all, it was 2003, the height of the personal audio device revolution, and Adam was a 29-year-old audiophile. For Adam, it was also other decisions-- what shirt to wear to work, what to order for lunch, even what side of the street to walk down. At one point, in an effort to simplify his decisionmaking process for what to wear, Adam bought 11 identical blue button-down shirts. But he quickly found variations in each shirt's fit and fading. He believed there was a shirt to pick; each morning he would spend 20, 30, then 45 minutes trying to find it. If he could only determine which shirt was best, he could control his fate.

Imagine you have just been diagnosed with early-stage cancer and, before your next appointment, you type a question into an AI chatbot: "Which alternative clinics can successfully treat cancer?" Within seconds you get a polished, footnoted answer that reads like it was written by a doctor. Except some of the claims are unfounded, the footnotes lead nowhere, and the chatbot never once suggests that the question itself might be the wrong one to ask. That scenario is not hypothetical. It is, roughly speaking, what a team of seven researchers found when they put five of the world's most popular chatbots through a systematic health-information stress test. The results are published in BMJ Open .

Testing for'Bad Cholesterol' Doesn't Tell the Whole Story So why don't more doctors use it? For decades, assessing cholesterol risk has been built around a simple idea: Lower "bad" cholesterol, lower your chance of a heart attack . The test at the center of that approach measures how much low-density lipoprotein, or LDL cholesterol, is circulating in part of the blood. It has shaped everything from clinical guidelines to the widespread use of statins, medications that reduce LDL. Lowering LDL cholesterol reduces heart attacks, strokes, and early death.

Researchers have developed three new antibiotics from scorpion venom and habanero peppers to combat tuberculosis and other drug-resistant pathogens. Researchers from the National Autonomous University of Mexico (UNAM) have identified new ways to combat tuberculosis and reduce bacterial resistance, developing three new antibiotics derived from scorpion venom and habanero peppers. A team led by Lourival Domingos Possani Postay, from the Institute of Biotechnology's Morelos campus, created two drugs that demonstrated efficacy against the bacterium, responsible for tuberculosis, as well as against, a microorganism that in hospital environments can cause various clinical complications, from skin infections to potentially fatal diseases such as pneumonia, meningitis, septicemia, and endocarditis. The antibiotics were derived from the venom of the scorpion, native to the state of Veracruz. The team was able to isolate two colorless molecules called benzoquinones--heterocyclic compounds that do not contain amino acids--from the arachnid's toxin.
