A Superconductor's 'Electric Memory'

A Superconductor's 'Electric Memory'

13.02.2000
Space & Physics
Weizmann Institute scientists have managed to explain how superconductors penetrated by magnetic fields 'remember' the physical properties of electrical currents
The Ins And Outs Of Acetylcholine

The Ins And Outs Of Acetylcholine

13.02.2000
Brain & Behavior
A team of scientists from the Weizmann Institute and France's Centre National de la Recherche Scientifique (CNRS) has recently shown that the acetylcholine neurotransmitter plays a double role in learning and memory.
Shooting The Messenger

Shooting The Messenger

Biochemistry, Cancer, Molecular and Cell Biology, Disease, Drugs & Diagnostics, Genetics
The age-old appeal to avoid 'shooting the messenger' is apparently left unheeded by the body's protein regulation system. Researchers at the Weizmann Institute of Science have recently uncovered one of the mechanisms underlying the synthesis and regulation of actin - the most abundant protein in eukaryotic cells. Their findings reveal an intricate autoregulatory system based on destroying actin's messenger RNA.    
Weizmann Institute Scientists Devise an Approach For 'Recruiting' an Immune System Response to Partial Spinal Cord Injuries

Weizmann Institute Scientists Devise an Approach For 'Recruiting' an Immune System Response to Partial Spinal Cord Injuries

01.02.2000
Brain & Behavior, Immunology
Several years ago, a team of Weizmann researchers found that immune cells known as macrophages may be 'recruited' to encourage repair and renewed growth of damaged nerve fibers.Profs. Schwartz and Irun R. Cohen now  propose adding additional immune cells, known as T-cells, to the damage-control battalion aimed at blocking the spread of spinal cord damage.
X-ray radiation from a synchrotron source can rapidly damage, in a very specific way, the structure of a protein, as seen by X-ray crystallography. The four images represent a series of electron density maps collected from the same protein crystal. Protein degradation is indicated by the disappearance of the disulfide bond (yellow bar, surrounded by empty blue cage) linking the carbon chains (white balls). These images represent the first-ever recording of experimentally-induced chemical bond breakage usin

Weizmann Institute Scientists Capture The First-Ever 3D Visualization Of How Molecules Break Apart When Exposed To X-Rays

Space & Physics, Biochemistry, Molecular and Cell Biology, Structural Biology
  Their findings may yield future measures for preventing radiation-induced health damages.      
Functional MRI Will Enable Non-Invasive Visualization of brain Cortical Columns

Functional MRI Will Enable Non-Invasive Visualization of brain Cortical Columns

25.01.2000
Space & Physics, Brain & Behavior, Disease, Drugs & Diagnostics, Diagnostic Techniques and Drugs
The accomplishment by Minnesota scientists, based on information gathered through optical imaging techniques innovated by Weizmann Institute scientists, should bridge the gap between neurophysiology and psychology by providing detailed insight into sensory perception and higher cognitive functions  
Blood Test For Schizophrenia

Blood Test For Schizophrenia

17.01.2000
Brain & Behavior, Immunology, Disease, Drugs & Diagnostics
A relatively simple blood test for diagnosing the mental illness schizophrenia has been proposed by researchers at the Weizmann Institute of Science. The study, conducted by Prof. Sara Fuchs and graduate student Tal Ilani of the Immunology Department, is to be published on January 16, in the Proceedings of the National Academy of Sciences, U.S.A.    
New Understanding Of A Key Control Mechanism In The Brain

New Understanding Of A Key Control Mechanism In The Brain

13.01.2000
Brain & Behavior, Disease, Drugs & Diagnostics
Weizmann Institute findings could provide new insights into a wide range of neurological disorders, including Alzheimer's disease, autism, and epilepsy  
X-Rays May Show The Way To Better Alzheimer's Drugs

X-Rays May Show The Way To Better Alzheimer's Drugs

27.12.1999
Disease, Drugs & Diagnostics
Weizmann Institute scientists have elucidated the means by which a plant substance blocks a key brain enzyme involved in Alzheimer's disease.  
Protein Teamwork Drives Damaged Cells To Self-Destruct

Protein Teamwork Drives Damaged Cells To Self-Destruct

12.12.1999
Disease, Drugs & Diagnostics
Researchers at the Weizmann Institute of Science have recently deciphered part of the cellular events underlying apoptosis -- programmed cell death. Their findings, published in Nature earlier this summer, provide important insights into cancer pathologies and their potential cures.
