Weizmann Institute scientists develop a new approach for directing treatment to metastasized prostate cancer in the bones.

Few things about growing older are as.inevitable and obvious as “going gray,?yet scientists have been unable.to explain the precise cause of this usually unwelcome transformation..In a report posted today on the Web site of the journal Science,.researchers from Dana-Farber Cancer Institute and Children’s Hospital.Boston say they have found the cellular cause of graying hair while.investigating th...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

A team of scientists at the Weizmann Institute of Science, led by Prof. Michal Schwartz of the Neurobiology Department, has come up with new findings that may have implications in delaying and slowing down cognitive deterioration in old age. The basis for these developments is Schwartz's team's observations, published today in the February issue of Nature Neuroscience, that immune cells contribut...

Weizmann Institute scientists discover a molecular security mechanism for keeping mutations in check

Everyone knows mutations ?genetic mistakes in DNA, the material of heredity ?are bad: The more mutations in the cell's DNA, the higher the risk of cancer developing. But in the last few years it has become clear that the very processes that generate mutations, if they take place at a relatively low frequency, can actually protect us from cancer. How does the body know how to keep these processes...

Weizmann Institute scientists develop a general 'control switch' for protein activity

Our bodies could not maintain their existence without thousands of proteins performing myriad vital tasks within cells. Since malfunctioning proteins can cause disease, the study of protein structure and function can lead to the development of drugs and treatments for numerous disorders. For example, the discovery of insulin’s role in diabetes paved the way for the development of a treatment bas...
