How to Measure Your Blood Pressure at Home So the Number Means Something

The Oldest Drug Habit on Record Is Betel Nut, Sucked by Foragers in Sulawesi Up to 25,000 Years Ago

Grooves in fossil teeth that nobody could explain, arecoline in the residue, and a frog-egg assay to prove the dose reached the brain. The Griffith University paper in Science Advances pushes human drug use back by more than ten thousand years.

Pennsylvania's Fourth Measles Death Is an 18-Year-Old in Mifflin County. America Last Lost Four in a Year in 1992

Nearly 700 cases in 38 counties, 133 in hospital, a hundred new infections in a week, and four unvaccinated dead in a month: two infants, a woman of forty and now a teenager with brain inflammation. The CDC has yet to count any of them.

An AI-Designed Lung Drug Made Six Ageing Clocks Run Backwards in a Small Trial. That Is Not the Same as Reversing Ageing

Rentosertib was built to treat pulmonary fibrosis. In 42 patients, blood proteins read by six independent clocks came out three to four years younger after a month. Independent doctors say a younger score is not a younger person.

A Brain Implant Let Paralysed People Speak and Wave at the Same Time, Through an Avatar, for the First Time

Edward Chang's team at UCSF decoded attempted speech and upper-body movement from the same electrodes on the motor cortex, so a patient could say hello and wave, or nod while saying yes. Two of three participants controlled the avatar.

A Bedroom That Is Not Quite Dark Is Linked to a Thicker, Stiffer Heart, in the First Study to Measure Both

Eleven thousand people wore a light sensor for a week. Three years later, those who slept in more than three lux, a very dim room, had thicker left ventricles and muscle that flexed less. The differences are small. Cardiologists still care.

Slow Breathing Made People Take More Risks, Not Fewer, in a Berlin Brain-Scan Study

Forty-one volunteers who breathed with a long exhale accepted riskier bets for money in an MRI scanner, and those whose heart rhythm responded most showed the strongest reward activity in the brain. A neat result, a small sample, a lesson about calm.

Intermittent Fasting Works About as Well as Eating Less, Because in the Trials That Is What It Turned Out to Be

Three randomised trials put time-restricted eating against ordinary calorie control or against nothing. The eating window on its own did little. Combined with eating less, it did what eating less does. What that means for anyone considering it.

Nobody Ever Found the Study Behind Eight Glasses of Water a Day, Because There Is Not One

A physiologist went looking for the origin of the rule in 2002 and came back empty. What the reference intakes actually say, why food and coffee count, how much the number varies between people, and when in a Gulf summer it genuinely matters.

Cold Showers and Ice Baths: A Dutch Trial Found Fewer Sick Days, a New Review Found Inflammation. Both Are Right

Three thousand Dutch adults who ended their showers cold took fewer sick days. A 2025 review of eleven trials found stress fell twelve hours after a plunge and inflammation rose. What is known, what is marketing, and why the first minute can kill.

The Finnish Sauna Study Everyone Quotes Is Real, and It Is Weaker Than the Wellness Industry Wants It to Be

Men who used a sauna four to seven times a week had far fewer sudden cardiac deaths over twenty years than men who went once. That finding launched an industry. What the study can and cannot support, and who should be careful.
