    Could Chaim Weizmann's Vision Be the Key to Solving the Energy Crisis?

    A hundred years ago, Chaim Weizmann – a preeminent chemist and namesake of the Weizmann Institute, as well as Israel's first president – proposed a method of producing biofuel. Today, researchers at the University of California are developing his concept. Has the time come for Dr. Weizmann's vision to be realized?

    World's First Artificial Cell Churns Out Proteins

    The Weizmann Institute's Prof. Roy Bar-Ziv had a dream: creating an artificial cell that actually works like a living cell. Now, after more than a decade of ""intense lab work,"" his team has created the world's first cell-on-a-chip, an exciting development with potentially game-changing applications. Israel21c reports.

  • Tough Science

    The Weizmann Institute's Nobel Prize-winning chemist Prof. Ada Yonath answers questions from Nature about persistence, gender, ribosomes, and what it takes to be a scientist.

    Gut Reactions

    Dr. Daniel Segrè's computer-simulated microbes let him study their role in biofuel, the human microbiome, and more. His work was inspired by a dinner conversation with a visiting Prof. Doron Lancet, after which Dr. Segrè pursued his postdoc in Prof. Lancet's Weizmann lab. Today, Dr. Segre's work is so promising that the Dept. of Energy gave him $1.4M.

    Not by Bread Alone: Neolithic People in Israel First to Farm Fava Beans, 10,000 Years Ago

    A Weizmann archaeobotanist and nuclear physicist identified the 10,200-year-old remains of cultivated fava beans in Israel. As Haaretz reports, this helps explain how humans settled down and became farmers, “ultimately leading to the rise of complex civilizations.” It could also help develop beans better able to cope with climatic extremes.

    Beautiful Sea Sapphire Can Make Itself Invisible in an Instant

    The sea sapphire has been called ""the most beautiful animal you've never seen,"" switching between vibrant blues, violets, reds, and … nothing. Now, as <em>New Scientist</em> reports, Weizmann scientists and colleagues in Eilat are learning how it changes color and becomes invisible – findings that could lead to new optical technologies.

    Even Just A Single Exposure To Roadway Particulate Matter Induces Transient Pulmonary Stress, Research Finds

    Air pollution is often in the form of particulate matter, or PM – particles small enough to be inhaled into the lungs. Near roadways, Weizmann researchers and colleagues found, the types and amounts of PM mean that a single exposure is enough to cause lung distress. As Clean Technica reports, this effect is far worse in major cities.

    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 <em>The Daily Mail</em> 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

    <em>Time</em> 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.
