    Sea Change, Climate Change

    The ocean covers more than 70 percent of Earth's surface – and rising. As our weather changes, Weizmann Institute scientists are studying the ocean, using everything from microscopes to satellites, to understand its relationship with our climate. What will the future bring?

    “Coral on a Chip” Cracks Coral Mysteries

    The world's corals are dying, with tremendous effects on climate and ocean health – however, much about coral, and why it dies, is still unknown. Now, Dr. Assaf Vardi and his team have created a new experimental platform – a ""coral on a chip"" – that lets them grow coral in the lab to study the structures' complicated lives at microscale resolution.

    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.

    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 Professor Finds Merit in Papal Document on Climate Change

    Renowned plant scientist and Professor Emeritus Jonathan Gressel spoke to the St. Louis Jewish Light about parasitic weeds, greenhouse gases, and the Pope's encyclical on climate change. Supporting the Pope's statement that manmade climate change is a global threat, Prof. Gressel says frankly: “there will be more global warming.”

    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.
