New synthetic molecules treat autoimmune disease in mice
A team of Weizmann Institute scientists has turned the tables on an autoimmune disease. In such diseases, including Crohn's and rheumatoid arthritis, the immune system mistakenly attacks the body's tissues. But the scientists ...

Social pressure falsifies memory: study
How easy is it to falsify memory? New research at the Weizmann Institute shows that a bit of social pressure may be all that is needed. The study, which appears Friday in Science, reveals a unique pattern of brain activi ...

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 ...

Uncovering the genome's regulatory code
Since the sequencing of the human genome in 2001, all our genes – around 20,000 in total – have been identified. But much is still unknown – for instance where and when each is active. Next to each ...

Scientists discover an organizing principle for our sense of smell
The fact that certain smells cause us pleasure or disgust would seem to be a matter of personal taste. But new research at the Weizmann Institute shows that odors can be rated on a scale of pleasantness, and this turns out ...

Mathematical model may lead to safer chemotherapy
Cancer chemotherapy can be a life-saver, but it is fraught with severe side effects, among them an increased risk of infection. Until now, the major criterion for assessing this risk has been the blood cell count: if the ...

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 ...

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.

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 ...

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 ...
