More than just neurons: Scientists create new model for studying human brain inflammation
by Salk Institute Human astrocytes (green) extending processes that wrap around the host blood vessel (magenta). Credit: Salk InstituteThe brain is typically depicted as a complex web of neurons sending and receiving messages. But neurons only make up half of the human brain. The other half—roughly 85 billion cells—are non-neuronal cells called glia. The most common...

Scientists on the brink of cure for heart disease – with drugs that ALTER your DNA
Are we on the brink of a cure for heart disease? That was the question being whispered by normally cautious cardiologists at the American Heart Association annual conference in Philadelphia last week. Over three packed days, a raft of game-changing scientific discoveries have been unveiled by the world’s leading specialists – many of which will...

Scientists discover a previously unknown way cells break down proteins
HARVARD MEDICAL SCHOOL At a glance: Scientists have discovered a previously unknown mechanism by which cells break down proteins that are no longer needed.These proteins are short-lived and modulate genes that support important neural, immune, and developmental processes.The mechanism could inform the design of therapies to treat conditions that arise when cells make too much...

Scientists Discover a New, Unexpected Way That Cancer Cells Spread
HEALTH31 July 2023 By DAVID NIELD Killer T cells surround a cancer cell. (NIH Image Gallery/Flickr/Public Domain) One of the challenges in treating cancer is stopping it from metastasizing, and a new study reveals one of the fundamental mechanisms through which this happens. Now we know about this mechanism, perhaps we can stop it. Key to this newly...
