    Controlling Electron Spin for Efficient Water Splitting

    Splitting water molecules to produce hydrogen for fuel holds promise for alternative energy. However, current methods of water splitting also form hydrogen peroxide, which adversely affects the process. Now, Prof. Ron Naaman and an international team have found a way to control the spin of electrons, resulting in hydrogen-peroxide-free water splitting.

    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.

    “We Base the Most Important Decisions of Our Lives on Smell”

    Haaretz interviews Prof. Noam Sobel about his intensive research into the sense of smell, which - it turns out - informs every area of our lives, from what we eat to whom we love. Among other innovative studies, he is investigating whether odors can help people trust robots and whether smell is involved in repeated miscarriages.

    Crystallization Made Crystal Clear

    Crystallization is a well-observed process; we all watch it every winter when ice crystals form on our windows. But no one had ever seen the process on a molecular level: the point at which the liquid changes states. Until now, that is. Prof. Ronny Neumann and colleagues developed a way to watch crystallization happen, verifying long-held theories.

  • Best People, Best Science

    The Weizmann Institute’s most important asset is its people. That’s why the Institute is committed to recruiting and nurturing some of the world’s brightest young researchers. Here, six impressive new scientists – Drs. Ronen Eldan, Ofer Firstenberg, Yifat Merbl, Neta Regev-Rudzki, Nir London, and Efi Efrati – share how the Institute is helping them make breakthroughs in areas ranging from malaria to optics.

  • Scientists Reveal New Way to Hide Secret Messages

    Invisible ink, wax tablets, secret decoder rings – we like to hide messages in plain sight. Now Weizmann scientists have created a new way to pass secrets along. As The Daily Mail puts it, the team “has used some rather nifty chemistry to come up with a way to use common chemicals such as cola as the encryption key to code and decode hidden messages.”

  • The Science of Crying

    Time 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.

  • Weizmann Professors Claim Israel Prize in Chemistry and Physics

    Profs. Meir Lahav and Leslie Leiserowitz have received the prestigious Israel Prize in chemistry and physics for revealing how certain molecules and ions assemble themselves. Their research, as Haaretz states, “forms the basis for understanding processes in nature that are used as a scientific foundation for the future development of drugs.”

  • Dr. Michal Leskes: Energizing the Future

    The Institute’s postdoc award for women in science, funded by generous donors, supports talented Israeli women such as Dr. Michal Leskes. The award meant she could do her postdoc at Cambridge; today, at the Weizmann Institute, her work includes improving the lithium-ion batteries we use for everything from cell phones to electric cars.

  • Tiny “Flasks” Speed Up Chemical Reactions

    Dr. Rafael Klajn and his team found that when spherical nanoparticles self-assembled into a cluster, empty spaces formed between them, as between oranges packed in a case. They put molecules in these “flasks” for chemical reactions – a process that turned out to be highly efficient, with wide-ranging potential applications such as drug delivery.
