Experiment May Help Size Up Neutrinos
01.03.2003
Particle Physics
Our planet is bombarded every second with a large number of chargeless, seemingly massless, particles that originate in nuclear fusion reactions that power the sun. They're called neutrinos.
How Humans Lost Their Scents
01.03.2003
Genetics
In at least one type of endeavor, humans can’t even begin to compete with their best friends. Dogs can be trained to sniff out drugs and explosives or to track down a crime suspect by smell. Why can’t we do the same? Scientists from the Weizmann Institute of Science and the Max Planck Institute for Evolutionary Anthropology propose an explanation for this ancient quandary.

The secret to its strength is a ring Weizmann Institute scientists have found what makes the bacterium Deinococcus radiodurans the most radiation-resistant organism in the world: The microbe's DNA is packed tightly into a ring. The findings, published in the January 10 issue of Science, solve a mystery that has long engaged the scientific community.

Prize to Weizmann Institute Professor for Landmark Work in Stem Cell Transplantation
12.12.2002
Prof. Yair Reisner of the Institute's Immunology Department will be awarded the Daniele Chianelli Prize on December 15, 2002, commemorating his work of over 20 years on incompatible stem cell transplantation. Bone marrow or stem cell tranplantation is a crucial part of the therapeutic strategy aimed at saving the lives of people with leukemia, malignant lymphoma, multiple myeloma and congenital blood disorders, such as thalassemia or severe immune deficiencies.
