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.

Genes, Neurons, and The Internet Found to Have Organizing Principles – Some Identical

06.11.2002
How do 30,000 genes in our DNA work together to form a large part of who we are? How do one hundred billion neurons operate in our brain?  The huge number of factors involved makes such complex networks hard to crack. Now, a study published in the October 25 issue of Science uncovers a strategy for finding the organizing principles of virtually any network – from neural networks to ecological food webs or the Internet.

New formula developed by Weizmann Institute physicists may improve rain prediction Weizmann Institute physicists have revealed that turbulence in clouds can accelerate rain formation. In a study published in Nature, they developed a formula that makes it possible to calculate how fast tiny droplets within clouds cluster into heavy, rain-producing drops. The research may provide an effective tool for rain prediction.

Astrophysics
The scientists tracked, for the first time, a star completing an orbit around a known unusual source of radiation (a black hole candidate) in the center of our galaxy. This discovery heralds a new epoch of high precision black hole astronomy and that might help us better understand how galaxies are born and evolve.

Genetics, Plants and Agriculture
Corn harvests on experimental plots and in farmers’ fields in four East and Southern African countries have yielded striking results in long-term trials of an innovative witchweed-fighting technology.
Bone Marrow Transplants May be Improved Due to the Uncovering of a Key Mechanism Responsible for Stem Cell Mobilization

Bone Marrow Transplants May be Improved Due to the Uncovering of a Key Mechanism Responsible for Stem Cell Mobilization

30.06.2002
Stem Cells, Immunology, Disease, Drugs & Diagnostics
Weizmann Institute scientists have uncovered a mechanism that enables stem cells to exit the bone marrow into the blood circulation of healthy donors as well as patients suffering from leukemia, other malignancies and blood disorders. Published in the current July issue of Nature Immunology, the findings may lead to more efficient clinical stem cell transplantations.
