Same signaling enzymes can trigger two different processes in the cell
Stroke, heart attacks and numerous other common disorders result in a massive destruction of cells and tissues called necrosis. It's a violent event: As each cell dies, its membrane ruptures, releasing substances that trigger ...

Insights into rare immune cells that keep blood stem cells in a youthful state may lead to better treatments
Hiding deep inside the bone marrow are special cells. They wait patiently for the hour of need, at which point these blood forming stem cells can proliferate and differentiate into billions of mature blood ...

Lesson in sleep learning: Associations formed in brains of sleeping volunteers remained intact when subjects were awake
Is sleep learning possible? A new Weizmann Institute study appearing today in Nature Neuroscience has found that if certain odors are presented after tones during sleep, people will start sniffing when they hear the tones ...

Why chemotherapy fails: Scientists show why leukemia often returns
The fight against cancer is not won in a single battle: Long after a cancer has been beaten into remission, it can return. The reason for this is under debate, and much is unclear. New research led by Weizmann Institute scientists ...

How cells brace themselves for starvation
Cells that repress their "bad time" pumps when a nutrient is abundant were much more efficient at preparing for starvation and at recovering afterward than the cells that had been genetically engineered to avoid this repression.
