Scientists are gaining insights into why Alzheimer's is more common in women. The answer involves genetics, hormones and sex-related brain differences.
This week, a scientific look at what makes us laugh. Here's a hint — a lot of it isn't funny. We talk to neuroscientist (and stand up comedian) Sophie Scott.
Researchers are using brain scans, blood and spinal fluid to detect early signs of Alzheimer's disease. These "biomarkers" may also offer a quicker way to test new Alzheimer's drugs.
Scientists often share their latest research on posters displayed at big conferences. Posters are a long-standing tradition, but one reformer says they're mostly terrible and need to change.
More than 600 people will take part in study to test a promising treatment for Huntington's disease, a fatal inherited condition. The experimental drug interferes with defective genetic machinery.
Scientists have found a way to transform electrical signals in the brain into intelligible speech. The advance may help people paralyzed by a stroke or disease, but the technology is experimental.
Fresh water quenches thirst almost instantly, but salt water doesn't. New research shows how cells in the gut and on the tongue help the brain keep just the right concentration of salt in our bodies.
Nearly two years after the U.S. said diplomats in Cuba had been injured in a series of "health attacks," many scientists say there's still no proof anyone was injured.
