Men eating ultra-processed foods gained more fat than those eating unprocessed meals, even with equal calories. Their hormone levels shifted in worrying ways, with testosterone falling and pollutants rising. Researchers say the processing itself, not ...

Scientists have finally uncovered direct genetic evidence of Yersinia pestis -- the bacterium behind the Plague of Justinian -- in a mass grave in Jerash, Jordan. This long-sought discovery resolves a centuries-old debate, confirming that the plague ...

Yale scientists discovered that cavefish species independently evolved blindness and depigmentation as they adapted to dark cave environments, with some lineages dating back over 11 million years. This new genetic method not only reveals ancient cave ...

Quantum scientists in Innsbruck have taken a major leap toward building the internet of the future. Using a string of calcium ions and finely tuned lasers, they created quantum nodes capable of generating streams of entangled photons with 92% ...

A Mediterranean diet alone is healthy, but when combined with calorie control, exercise, and support, it cuts type 2 diabetes risk by 31%. The PREDIMED-Plus study followed almost 5,000 participants for six years, making it Europe's largest nutrition ...

Harvard scientists have uncovered that lithium, a naturally occurring element in the brain, may be the missing piece in understanding Alzheimer's. Their decade-long research shows that lithium depletion--caused by amyloid plaques binding to it- ...

For people with macular telangiectasia type 2 (MacTel), an orphan retinal disorder that gradually destroys central vision, there have long been no approved treatment options. But now, a new study sponsored by Neurotech Pharmaceuticals and spearheaded ...

Using cannabis to self-medicate comes with hidden dangers--new research shows these users face higher paranoia and consume more THC. Childhood trauma further amplifies the risks, especially emotional abuse, which strongly predicts paranoia.

A Mediterranean-style diet was linked to lower dementia risk, especially in people with high-risk Alzheimer's genes. The strongest benefits were seen in those with two APOE4 copies, showing diet may help offset genetic vulnerability. Researchers say ...

Researchers propose that the U.S. could safely drop adult tetanus and diphtheria boosters, saving $1 billion annually, since childhood vaccinations provide decades of protection. Evidence from the U.K. shows that skipping boosters has not led to ...
