    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.

    Matthew Modine: It's Easy Being Green

    The Miami Herald interviews actor Matthew Modine about his new role: environmental advocate. Modine has long been vocal about protecting our resources, and set up a program to encourage bike riding. Impressed by Weizmann science, he has now partnered with us at the American Committee to share the Institute's amazing environmental research.

    Marine Green Slime to Save the Planet

    Weizmann's Dr. Assaf Vardi led a team of more than 30 scientists on a trip to the North Atlantic to study phytoplankton. These tiny algae are crucial to Earth's ecology and are key to climate regulation; in fact, they play an ancient and outsized role in our environment.

    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.""

    Bacteria Engineered to Make Sugar From Carbon Dioxide and Feed World

    All forms of life “fix” carbon: adding energy to CO2 to, as The Jerusalem Post reports, “turn it into the sugars that are the required starting point needed for life processes.” Prof. Ron Milo has engineered bacteria to improve carbon fixation, which could help meet the need to supply more food to more people, while using less fossil fuel and taking up less land.

    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.

    Saving Reefs One Polyp at a Time

    Coral reefs are the canaries in our environmental coal mine, serving as front-line warnings of damage from climate change. They are also, as <em>The Scientist</em> says, ""notoriously difficult to study."" Until now. Weizmann scientists have ""discovered how to study coral organisms in unpresented detail"" – a breakthrough that could help grow healthy new coral.

    What Gives the Beach That Smell? Sulfur-Making Algae

    One of the most evocative smells on Earth is arguably the smell of the sea – but what <em>is</em> that smell? As <em>Wired</em> reports, Weizmann scientists found the answer: a sulfur compound produced by an algae. The chemical could even play a role in controlling Earth's temperature, helping fight climate change. That makes the beach even more enjoyable!
