    How Do Marine Mollusks Process Food Without Teeth?

    Mollusks use hardened plates to break down food. In findings that could lead to better materials, Weizmann scientists have now shown how the plates work, saying: ""The solutions evolved by organisms during hundreds of millions of years have produced sophisticated materials … with much more innovative design than the best"" that humans can do.

    Gut Reactions

    Dr. Daniel Segrè's computer-simulated microbes let him study their role in biofuel, the human microbiome, and more. His work was inspired by a dinner conversation with a visiting Prof. Doron Lancet, after which Dr. Segrè pursued his postdoc in Prof. Lancet's Weizmann lab. Today, Dr. Segre's work is so promising that the Dept. of Energy gave him $1.4M.

  • "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.

    Bad Smells Impair Learning

    Performance usually improves with practice, but not if training is a rotten time. A new study shows that people's ability to identify noises declines when the sounds are paired with putrid smells–a phenomenon that may allow our brain to detect danger more quickly.

    Dr. Karina Yaniv to be honored with LE&RN's 2016 Wendy Chaite Leadership Award

    The Lymphatic Education & Research Network has announced that it is awarding its prestigious Wendy Chaite Leadership Award to Weizmann's Dr. Karina Yaniv. With funding support from the organization, Dr. Yaniv recently showed – for the first time – how the lymphatic system develops. The award will be presented on March 23 by actor Kathy Bates.

    The Science of Crying

    <em>Time</em> reports on research that investigates why we cry – or don't. Humans are the only animals that cry for emotional reasons, and scientists across the world are investigating the phenomenon, including the Weizmann Institute's Prof. Noam Sobel. His finding that women's tears may inhibit sexual arousal in men garnered global headlines.

    Pigs in Israel Originated in Europe, Researchers Say

    Archaeologists – including Weizmann's Prof. Steve Weiner – taking part in a massive project to reconstruct ancient Israel have shown that Israeli pigs are of European, not Middle Eastern, stock, and that they probably arrived with the Philistines about 3,000 years ago. Says Prof. Weiner, ""Archaeologists take pigs very seriously.""

    Scientists Urge New Approaches to Plant Research

    Michigan State's Dr. Robert Last and Weizmann's Dr. Ron Milo write in Science that, as Earth's resources run out and the human population grows, we must turn to plants if we are to survive, including studying them in an interdisciplinary way.
