Chemistry
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.
Imaging Method Reveals Remarkable 'Architecture' of the Working Brain
16.12.1997
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.
In Gulliver's Garden: Tiny Tomatoes Speed Genetic Engineering of Plants
10.12.1997
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.
Windows on your Mind: Weizmann Institute Scientists Reveal That Imagination Can Enhance Visual Perception
09.12.1997
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.
New Delivery System May Improve Gene Therapy
03.12.1997
Disease, Drugs & Diagnostics
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.
Cell 'Suicide' Gene Linked To Metastasis
13.11.1997
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."
Protein 'Heroes' Block Genetic Mutations
12.11.1997
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.
Therapeutic Effects of Garlic Clarified by Weizmann Institute Research
14.10.1997
Disease, Drugs & Diagnostics
REHOVOT, Israel - October 14, 1997 - Garlic is believed to work wonders, from fighting disease to keeping away vampires. Now two studies conducted at the Weizmann Institute of Science have uncovered a molecular mechanism which may be the basis for some of garlic's therapeutic effects. The researchers were able to study how garlic works at the molecular level thanks to their unique biotechnological procedure for producing large quantities of pure allicin, garlic's main biologically active component.
Tune Into This: Weizmann Institute Study Provides Evidence For a Radio-Like Mechanism in the Brain
14.10.1997
Brain & Behavior
REHOVOT, Israel - October 14, 1997- Research conducted at the Weizmann Institute of Science may give a whole new meaning to the phrase "stay tuned." Institute scientists have found evidence that when the brain interprets sensory input, it uses a mechanism remarkably similar to that of an FM radio.
The Mathematical Tourist: Weizmann Institute Hosts Students from C.I.S.
13.10.1997
Science Education
REHOVOT, Israel - October 13, 1997 - An elite group of high-school mathematics students from the former Soviet Union have learned that, if you want to get to Israel, you have to do your homework. These 19 students, who visited Israel recently, were chosen from among 3,000 participants in a special math enrichment program designed at the Weizmann Institute of Science and administered by Israel's Foreign Ministry.
