Ancient mass grave reveals how a pandemic wiped out a city 1,500 years ago

A newly confirmed mass grave in ancient Jordan offers chilling insight into one of history’s first pandemics. Hundreds of plague victims were buried within days, revealing how the Plague of Justinian devastated entire communities. The findings show that people who usually lived spread out across regions were suddenly concentrated in death. It’s a powerful reminder that pandemics don’t just spread disease—they reshape how societies live and collapse.

These 80-year-olds have the memory of 50-year-olds. Scientists now know why

A rare group of adults over 80, known as SuperAgers, are rewriting what we thought was possible for the aging brain. With memory abilities comparable to people decades younger, their brains either resist or withstand the damage typically linked to Alzheimer’s disease. Decades of research reveal that their social lifestyles and unique brain biology may hold the key to preserving cognitive function. Scientists believe these insights could pave the way for new strategies to delay or even prevent dementia.

For the first time, scientists pinpoint the brain cells behind depression
For the first time, scientists pinpoint the brain cells behind depression

Scientists have identified two specific types of brain cells that behave differently in people with depression, offering a clearer picture of what is happening inside the brain. By analyzing donated brain tissue with advanced genetic tools, the researchers found changes in neurons linked to mood and stress, as well as in immune-related microglia cells. These differences point to disruptions in key brain systems and reinforce that depression is rooted in biology, not just emotions.

Simple “gut reset” may stop weight gain after Ozempic or Wegovy
Simple “gut reset” may stop weight gain after Ozempic or Wegovy

A new minimally invasive procedure may help people keep weight off after stopping popular drugs like Ozempic and semaglutide—something most patients struggle with. In a clinical trial, those who underwent a technique called duodenal mucosal resurfacing regained far less weight compared to others after discontinuing the medication. The procedure works by renewing the lining of the upper small intestine, potentially “resetting” metabolism and preserving the benefits of weight loss.
