    Weizmann Institute Scientists Discover How to Manipulate the Brain to Control Maternal Behavior in Females and Reduce Aggression in Males

    Why are there gender-specific roles in caring for offspring? Drs. Tali Kimchi and Ofer Yizhar have found a neurobiological answer, and – using state-of-the-art techniques – were able to control maternal behavior and male aggression in mice. Their work could also shed light on disorders like postpartum depression, aggression, and autism.

    In Search of the Wild Fava Bean

    The wild faba - today, fava - bean is thought to be extinct. Now, however, Dr. Elisabeth Boaretto has identified the oldest known beans - about 14,000 years old. Understanding how the wild fabas survived can help scientists grow hardier fava crops today. Favas are a major source of nutrition in many parts of the world.

    Stanley Fischer, Jesse Roth, Lia Koenig Among Those to Receive Weizmann Institute Honorary PhDs

    Six distinguished figures from the worlds of art and science are to receive honorary doctorates from the Weizmann Institute of Science: Prof. Marvin L. Cohen, Prof. Stanley Fischer, Lia Koenig Stolper, diabetes researcher Prof. Jesse Roth, Prof. Simon Schama, and Dr. Herbert Winter. Read more about these deserving individuals.

  • Weizmann Institute Scientists Show That an Odorant's Molecular Structure is What Determines Its Pleasantness, Contradicting the Notion That Smell is Subjective

    Weizmann scientists find that the perception of an odor's pleasantness is hard-wired to its molecular structure, indicating that smell may not be as subjective as once thought.

    Gut Microbes Contribute to Recurrent "Yo-Yo" Obesity

    Yet again, new research from Dr. Eran Elinav and Prof. Eran Segal is making global headlines and potentially changing lives. Most people have experienced the rebound effect of dieting - losing weight only to regain it, and then some. Now the Weizmann team has determined why this happens, and has identified potential solutions.

    Weizmann Institute is Number One in ERC Grants

    The European Research Council (ERC) awards highly competitive grants to the top European research institutes and universities. Recent analysis of the success rates for all grants awarded from 2007 – 2013 puts Weizmann in first place, with an astonishing 35% of its proposals approved. In comparison, the average success rate is around 10%.

    Your Symptoms? Evolution's Way of Telling You to Stay Home

    Why, when we get sick, do we feel bad? We assume that our aches, pains, fever, etc., are from a virus or bacteria, but now there is a novel hypothesis: evolution. Of course, staying home when sick keeps others from falling ill, too, but this may not be purely altruistic: the genes that trigger symptoms are actually focused on their own survival.

    Blast of Thin Air Can Reset Circadian Clocks

    The low pressure in airplanes can make traveling unpleasant – but it could also ease jetlag, finds Dr. Gad Asher. Every cell in the body contains a circadian clock, and when these clocks are disrupted, imbalances result. Dr. Asher's findings could affect how airlines moderate cabin pressure. He and his team are now seeking ways to help travelers.

    Why do Female Mice Attack Others' Pups? Blame it on Pheromones

    Lab mice lose many of their natural traits; e.g., lab females will care for others' pups, unlike their wild cousins. Dr. Tali Kimchi has developed a model that lets her explore, for the first time, the biological roots of aggressiveness in females, particularly toward pups, and found that pheromones are the key. Her work could aid gender-specific drug development.

    The Scent of a Handshake

    Why do we shake hands? Why do animals smell each other? These two actions apparently serve the same evolutionary purpose. A new study by Prof. Noam Sobel's lab shows that after shaking someone's hand, we sniff our own hands twice as much – and the hand we sniff depends on the shakee's gender. Such subliminal sniffing seems to help convey social information.
