    Scientists Identify a Viral Communication System

    <em>The Scientist</em> reports on research from the lab of Prof. Rotem Sorek, who discovered that viruses leave ""messages"" for other viruses, enabling subsequent generations to decide whether to stay quiet or infect the host. The study has been called ""annoyingly good.""

    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.""

    Nobel Laureate Talks Life Expectancy, Antibiotics

    Weizmann's Prof. Ada Yonath, winner of the 2009 Nobel Prize in Chemistry, recently delivered the 21st Efraim Racker Lecture in Biology and Medicine at Cornell University. Her work on ribosomes is shedding light on antibiotic resistance. Cornell's synchrotron X-ray facility worked with Prof. Yonath on her award-winning technique.

    Israeli Woman is ""Europe's Top Young Researcher""

    Dr. Naama Geva-Zatorsky, who performed her doctoral work at Weizmann, has been awarded a prestigious 2012 L'Oréal-UNESCO For Women in Science international fellowship. She is currently a postdoc at Harvard Medical School, where she investigates the use of probiotics to treat disease.

    Why Yo-Yo Dieters Often Can't Keep the Weight Off

    People all over the world repeatedly go through the long, frustrating, defeating struggle known as ""yo-yo dieting"": they lose weight, only to gain it again, over and over (and over). Now, new research from Dr. Eran Elinav and Prof. Eran Segal shows why: the gut microbiome keeps resetting the body to gain weight.

  • Former 'Village Fool' Takes the Prize

    Prof. Ada Yonath, one of Israel's most distinguished scientists, was long treated ""like the village fool"" by colleagues who had doubts about her findings in the rather obscure and complex field of ribosomal crystallography. Now, she has won one of the world's most prestigious prizes - the L'Oréal-UNESCO Award for Women in Science.

  • "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.

    How Jetlag Disrupts the Ticks of Your Microbial Clock

    <em>National Geographic</em> covers recent findings from the labs of Dr. Eran Elinav and Prof. Eran Segal. The two showed that our gut biota and our biological clocks must be in sync, or problems like obesity can occur. People with disrupted sleep schedules, such as shift workers or jet-lagged flyers, are at the most risk.

    Yale Participates in International Metabolic Research Alliance

    Scientists from Yale University, the Jackson Laboratory, the University of Connecticut, and the Weizmann Institute of Science have come together to form the Metabolic Research Alliance. As the Yale Daily News announces, the global group will study metabolic diseases, such as diabetes and obesity.
