    These Foods Speed Up Circadian Rhythm And Increase Lifespan

    As we age, our biological clocks wind down – but why? Weizmann's Dr. Gad Asher has found a link between the clocks and a group of metabolites called polyamines. Found in many foods, polyamines could help us fight aging. reports on the research and a polyamine-laden diet, including soybeans, corn, green peas, blue cheese.

    The Imperative of Studying Aborted Embryonic Tissue

    <em>Haaretz</em> interviews Weizmann's Dr. Karina Yaniv, ""a chemist and biologist conducting groundbreaking research in embryonic development [who] tackles the mother of all questions: When does life begin?"" She explains why her basic research is so crucial, and why studying aborted fetal tissue is not only acceptable, but an obligation.

    40 Trillion Bacteria on and in Us? Fewer Than We Thought.

    <em>The New York Times</em> covers the finding by Weizmann scientists that turned a long-held number on its head. For decades, scientists believed that we had far more bacteria on and in our bodies than human cells: in fact, 10 times more. The Weizmann finding reveals that the real proportion is more like 1:1 – and that, in fact, at times we can be more human than ""bug.""

    Regenerative Medicine Study Underscores Lung Generation Capacity

    Recent Weizmann Institute research found that the heart had an unexpected, unknown capacity for regeneration, which could lead to treatments to help it heal after a heart attack or other trauma. This work is also applicable to cystic fibrosis, where another organ – lungs – also needs to be regenerated and repaired.

    Could Your Healthy Diet Make Me Fat?

    <em>The New York Times</em> covers Dr. Eran Elinav and Prof. Eran Segal's findings that people differ in their response to the same foods, which helps explain why diets – from vegan to paleo – work well for some people, but get poor results for others. The team examined metrics for over 800 people, and were able to use the data to create healthy diets for others.

    Study Gives Insight Why Females Are Prone to Eating Disorders

    As <em>Haaretz</em> reports, new research by Prof. Alon Chen shows that a ""brain receptor regulates stress responses differently in male and female mice,"" and the way females eat is affected. In fact, female mice were generally impacted more severely by stress. The stress-regulating protein is located in the hypothalamus, which also plays a role in metabolism.

  • "Trained" bacteria can lead to better biofuels

    <em>The Jerusalem Post</em> reports on the Weizmann Institute discovery that bacteria are not only not dumb, but have the ability to anticipate and plan for events. The research, which owes much to Pavlov's experiments with training dogs, has implications for creating better biofuels, among other options.
