February 5, 1999
REHOVOT, Israel - February 5, 1999 - In bone marrow transplantation, a patient receives a transfusion of stem cells, which migrate to the patient's bone marrow and start producing new, healthy blood. But many transplants fail because, usually, very few stem cells make their way f...

May 16, 2000
Draping the earth and entire universe in a thin, ever-present veil, their origin remains one of the greatest puzzles of cosmology. However, the mystique of gamma rays -- particles of light comprising the most energetic and penetrating form of electromagnetic radiation -- may soon...

July 1, 1999
In an experiment described in the May 20 issue of Nature, Weizmann Institute scientists have succeeded -- for the first time -- in measuring an electronic charge one-fifth the charge of a single electron. This is the smallest electronic charge that has ever been measured....
