Weizmann Institute Astrophysicist Hot on the Tracks of a New "Strange" Star

12.01.1998
REHOVOT, Israel - January 12, 1998 - A new "strange" star is suspected to be lurking in our galaxy - and a Weizmann Institute astrophysicist is hot on its tracks.

Future treatments for diabetes may correct the underlying causes of this prevalent metabolic disorder rather than just treat its symptoms. An important step in this direction has been made by Prof. Yehiel Zick of the Weizmann Institute's Molecular Cell Biology Department.

Two managers have run into a delicate problem. Each has received a complaint from a company employee on a sensitive matter. In both cases, the complainer has requested to keep his identity confidential. The managers would like to determine whether the same person has complained to both of them, but how can they do this without revealing to each other their complainers' identity?

Catalysts are the pacesetters of the chemical industry, speeding reactions that are vital to the manufacture of a host of products such as drugs, synthetic fibers and plastics. Now researchers at the Weizmann Institute of Science have found that a catalyst's performance can be dramatically improved by adjusting the structural orientation of its molecules.

Brain & Behavior
REHOVOT, Israel - December 16, 1997 - With thousands of neurons firing signals in all directions and forming trillions of possible connections, you'd expect the working brain to be a messy place. Yet a new study conducted by researchers from Max Planck Institute of Psychiatry in Martinsried, Germany, and Israel's Weizmann Institute of Science reveals that brain cells engaged in different tasks in the visual cortex form "mosaics" which are amazingly orderly and elegant.

Plants and Agriculture
REHOVOT, Israel - December 10, 1997 - A tiny tomato, dubbed "Micro-Tom," may mean big news for genetic engineering. The Lilliputian plant, adapted for research by Dr. Avraham Levy of the Weizmann Institute of Science, is the key to a new method that may speed the process of unraveling the genetic code of plants, making it easier to identify and use commercially valuable genes.

Brain & Behavior
REHOVOT, Israel - December 9, 1997 - Conjuring up images in the "mind's eye" enhances our ability to see what's really there, Weizmann Institute scientists have found. However, imagination greases the wheels of perception only when the images are drawn from short-term memory, the researchers report in the current issue of the Journal of Cognitive Neuroscience.

REHOVOT, Israel - December 3, 1997 - In the genes of an organism, as in real estate, location is key. The functioning of any gene is significantly affected by its exact placement on the chromosome. However, scientists currently have no means of delivering a new gene to a predetermined location in a cell's chromosomes during genetic manipulation, such as gene therapy.

Genetics
REHOVOT, Israel - November 13, 1997 -A Weizmann Institute of Science study reported in the November 13 issue of Nature provides new evidence for an intriguing theory about the development of metastasis. According to this theory, one of the factors contributing to metastasis - the spread of cancer from the site of the primary tumor to other body organs - is a loss of a mechanism by which cells "commit suicide."

Biochemistry
REHOVOT, Israel - November 12, 1997 - Researchers at the Weizmann Institute of Science have discovered that two repair proteins perform a truly "heroic" act, stopping genetic mutations dead in their tracks. In a study reported in the November 14 issue of the Journal of Biological Chemistry , Institute researchers describe how these proteins "fling themselves" onto damaged genes, which, if replicated, lead to the formation of mutations.
