    Making Spines from Sea Water

    Following up on earlier research - and using technologies that did not exist then - Profs. Lia Addadi and Steve Weiner answered long-held questions: where do sea urchins get the calcium ions they need to build their spines? The answer: they ""drink"" sea water, even as larvae. And it turns out that other organisms use the same surprising process.

    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.

    How to Mix the Perfect Cocktail

    The fine art of mixing drug cocktails - such as for cancer treatment - is incredibly complicated, especially once you get into three or more ingredients. The numbers of possible interactions and side effects are virtually infinite. Now, a new model from the lab of Prof. Uri Alon lets scientists compare combinations of drugs to determine which work well together, and with the fewest side effects. This is a major step forward in personalized medicine.

    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.

    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.
