Natural killer cells act as the immune system’s rapid-response team, but the stress of anxiety and insomnia may be quietly thinning their ranks. A study of young women in Saudi Arabia found that both ...

A single signaling pathway controls whether immune cells attack or befriend cells they encounter while patrolling our bodies, researchers at Stanford Medicine have found. Manipulating this pathway ...

Mouse research shows tattoo pigments move into lymph nodes within minutes and persist for months Ink triggered immune-cell death, chronic inflammation and weakened response to an mRNA COVID shot ...

The tiny chips hitch a ride on immune cells to target inflammation in the brain. Scientists hope to kick off clinical trials within three years. From restoring movement and speech in people with ...

More than a century ago, Alois Alzheimer noted unusual changes in brain fats, which he described as "lipoid granules," along with the buildup of amyloid‐beta (amyloid) plaques and tau protein tangles.

Megan Molteni reports on discoveries from the frontiers of genomic medicine, neuroscience, and reproductive tech. She joined STAT in 2021 after covering health and science at WIRED. You can reach ...

Researchers have uncovered surprising evidence that anxiety may be controlled not by neurons but by two dueling groups of immune cells inside the brain. These microglia act like biological pedals—one ...

Like the seeds of a forest, a few cells in embryos eventually sprout into an ecosystem of brain cells. Neurons get the most recognition for their computing power. But a host of other cells provides ...

Pulsing ultrasound waves through the brain could improve survival after a type of stroke by helping to clear out inflammatory dead blood cells, according to a study in mice. The approach, which ...

Lab-grown “reductionist replicas” of the human brain are helping scientists understand fetal development and cognitive disorders, including autism. But ethical questions loom. Brain organoids, which ...

Research on human brain organoids (HBOs) is directly challenging how biobanks and biomedical institutes recruit volunteers. That is what a new study by Japanese researchers in Frontiers in Genetics ...
