    A Rusty Green Early Ocean?

    How were the Earth's solid deposits of iron ore created? While researching possible conditions on Mars, Dr. Itay Halevy discovered “green rust“ - rare today, but apparently common billions of years ago. While this would have been just one of several means of iron deposition, green rust seems to have delivered a large proportion of iron to our early ocean.

    Science Tips, November 2014

    Three updates from the labs of the Weizmann Institute: at last, water on Mars explained; identifying an unusual zinc-pump mechanism that may be faulty in Alzheimer's disease; and finding that microbes that breathe sulfur prefer it to be light.

    Weizmann Scientist Stresses Value of ""Eureka Moments""

    The Institute's Prof. Brian Berkowitz visited Arizona to speak about ensuring safe drinking water, an increasingly critical topic worldwide. The Jewish News talked with Prof. Berkowitz, who addressed of the importance of basic research, particularly in creating the ""accidental"" discoveries that can lead to the greatest breakthroughs.

    Israeli Tech Seeks to Undo the Damage of Pesticides

    The Green Revolution may have saved a billion people from starvation, but at a price we are just now reckoning: a huge increase in the use of environment- and health-wrecking pesticides and chemicals. But with technology developed at the Weizmann Institute and commercialized by Israeli start-up Catalyst AgTech, these consequences may be reversed.

    California Drought: What Would Israel Do?

    California's devastating drought is leading it to turn to Israel – another semi-arid state – for help. As Prof. Brian Berkowitz says, Israel is ""a microcosm of what needs to be done."" When it comes to achieving water security, Israel's decades of success in water management just might provide the life vest California needs.

    Institute Develops Process to Protect Groundwater

    The Jerusalem Post reports that Weizmann and an agrochemicals firm are commercializing a new technology to stop toxic pesticides from getting into groundwater. Based on research by Prof. Brian Berkowitz and Dr. Ishay Dror, the method employs environmentally friendly substances to help protect our water.

    The Secret of Seawater Spines

    As <em>Nature World News</em> reports, Weizmann Profs. Lia Addadi and Steve Weiner have found that sea urchins form their spines in a very different way than scientists imagined: they ""drink"" seawater to get the crucial calcium ions.

    Climate Models Reveal Liquid Once Flowed on the Mars Surface – But Only Lasted for ""Short"" Periods at a Time

    The U.K.'s <em>Daily Mail</em> reports on Weizmann Institute and Brown University research showing that water once flowed on Mars. The scientists' climate model revealed that periodic warming melted ice into liquid. The <em>Daily Mail</em> points out that evidence for water has been found before, but that ""this is the first study to suggest water was episodic, not permanent.""

    As CO2 Acidifies the Oceans, Scientists Develop a New Way to Measure its Effect on Marine Ecosystems

    Increased CO<sub>2</sub> from climate change is making oceans more acidic; as reports, this makes it harder for corals to build their calcium-carbonate skeletons. Now, Weizmann Institute and Hebrew University researchers have found a new way to measure the impacts of CO<sub>2</sub> on coral reefs; this can provide ""essential information"" on climate change.
