    Three updates from the Weizmann Institute: discovering how the tiny, beautiful sea sapphire changes color – and even becomes invisible; using light to get nanoparticles to self-assemble could lead to rewritable paper, contaminant removal, and drug delivery; measuring how fast bacteria grow sheds new light on how our microbiome is tied to our health.

    Germs, Humans, and Numbers

    Our bodies are full of bacteria, which comprise the microbiome – now often called the ""second genome"" because of its crucial role in many aspects of our lives. But how much bacteria is there? The accepted ratio was 10:1 – meaning 10 times as many microbes as human cells, making us mostly microbiota. But Weizmann scientists have now shown it's much more equal.

    Gut Microbes Contribute to Recurrent "Yo-Yo" Obesity

    Yet again, new research from Dr. Eran Elinav and Prof. Eran Segal is making global headlines and potentially changing lives. Most people have experienced the rebound effect of dieting - losing weight only to regain it, and then some. Now the Weizmann team has determined why this happens, and has identified potential solutions.

    Eating Air, Making Fuel

    The process of carbon fixation is crucial to life on earth – and yet it puts too much harmful carbon dioxide, a greenhouse gas, into the atmosphere. Prof. Ron Milo's lab has engineered carbon-fixing bacteria to create sugar – fuel – from CO2. The team hopes that, in the future, their insights could lead to ways of storing energy or growing crops with higher yields, better suited to the coming world.

    Viruses Overheard Talking to One Another

    For the first time, viruses have been found to communicate with one another, leaving short “posts” for kin and descendants. The messages help the viruses reading them to decide how to proceed with the process of infection.

    Science Tips, October 2012

    Three updates from the Weizmann Institute: how bacteria that live with arsenate are able to identify it; previously unknown stem-cell ""bodyguards"" in the bone marrow; and a finely tuned immune system ensures response to common ills.

    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?
