Adults with atrial fibrillation (AFib) who are not diabetic but are overweight and took the diabetes medication metformin after a rhythm-correction procedure had decreased risk of AFib episodes for a year. Weight loss would usually be a confounder, since lifestyle changes such as that are often a big help, but in the data sample the weight changes were low.

In the various 'Predator' films, the alien hunter can see across various spectra while enabling camouflage from our vision.

That happens in nature. Octopuses, squids, and the scariest of them all, cuttlefish, in the cephalopod family have evolved the ablity to modify their skin to blend in with the environment. That is due to the presence of xanthommatin, a natural pigment with color-shifting capabilities.

The older you get, the more frail you become. The more frail you become, the greater the risk of falling, hospitalization, and shorter life expectancy.

Doctors talk about physical activity to reduce frailty but less attention is paid to biology. A new paper suggests that the hypothalamic–pituitary–gonadal (HPG) axis, the body’s system of regulating production of the hormone testosterone, can impact frailty.

"Suggests" means this is only EXPLORATORY, not human science, but a relationship between 

Actors, artists, and musicians are rightly worried about the impact of AI on their incomes but doctors and scientists welcome the help. They know typewriters didn't make literature worse than writing in longhand and "AI" - LLMs - likewise removes the 'how' of information access so thinkers can get to the 'why.'

In modern government-controlled healthcare, doctors are more pressed for time per patient than ever. Often while relying on incomplete information. Electronic health records contain vast amounts of patient data but much of it remains difficult to interpret quickly, and that is even more challenging for patients with rare diseases or unusual symptoms.

When you picture a black hole, you probably picture in the center of a galaxy with matter swirling toward it. You're not wrong but that is why the exception proves the rule.

A recent study detected a surprising tidal disruption event where a black hole outside the center of a galaxy is tearing apart a star. Even stranger and defiance of black hole lore, the delayed and powerful radio outbursts suggest previously unknown processes in how black holes eject material over time. Designated AT 2024tvd, it is to-date the fastest-evolving radio emission ever observed from a black-hole-driven stellar disruption.

The process by which the nervous system continuously receives and interprets the body’s physiological signals to keep vital functions running smoothly, a "sixth sense" called interoception that tells your brain when you need to breathe, when your blood pressure declines or when you have an infection, is getting some star power; a Nobel laureate neuroscientist.

And an NIH grant.
