    Natural Metabolite Might Reset Aging Biological Clocks

    As we age, our biological clocks wind down – but why? Dr. Gad Asher, who studies circadian clocks – genetic mechanisms that keep us in tune with cycles of day and night – has identified a link between the clocks and a group of metabolites called polyamines. Found in many foods, polyamines could fight aging – as they did in Dr. Asher's mice.

  • Birth of an Enzyme

    Scientists from the Weizmann Institute and the University of Washington, Seattle, successfully created a new type of enzyme for a reaction for which no naturally occurring enzyme has evolved.

    Science Tips, July 2013

    Three updates from the Weizmann Institute: teaching nanowires to assemble themselves, which could improve devices such as lasers and solar cells; outlining the 10-stage pathway that turns cholesterol into a dangerous toxin in potatoes; identifying the traffic-pattern-like nature of gene transcription could lead to a new generation of drugs.

    Nobel Prize in Chemistry 2013

    In the 1960s, Arieh Warshel and Michael Levitt were scientists at the Institute when they developed a computer program to model large biological molecules. Now, along with colleague Martin Karplus, they have received the 2013 Nobel Prize in Chemistry ""for the development of multiscale models for complex chemical systems.""

    New Hope for Gaucher Patients

    Gaucher disease, a genetic disorder most prevalent among Ashkenazi Jews, is devastating for sufferers and their families. Now, scientists in Prof. Tony Futerman's lab have discovered a new cellular pathway implicated in the disease. Their findings may offer a new therapeutic target for managing treatment of Gaucher and related disorders.
