    First Oceans May Have Been Acidic

    Looking back at the very earliest oceans, Dr. Itay Halevy found that they started off acidic and gradually became alkaline. His work sheds light on how levels of ocean acidity in the past were controlled by carbon dioxide in the atmosphere, an important process for understanding the effects of climate change, as today the oceans are again becoming acidic.

  • 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.

  • 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.

  • 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 The Scientist 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.

  • Better Energy for a Brighter Future

    Our rapidly changing climate makes it more imperative than ever to have reliable, affordable forms of energy. As head of the Institute’s Alternative Energy Research Initiative, Prof. David Cahen is helping to make this happen – both through his own work and by issuing grants to Weizmann scientists pursuing alternative energy solutions.

  • “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.

  • 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.

  • It’s Hot Outside. Could This Machine be the Answer to Global Warming?

    It’s hot outside – and getting hotter. The Times of Israel examines whether Weizmann’s Prof. Jacob Karni might have developed a solution, saying that he and “an entrepreneur have patented a device that extracts carbon dioxide from the atmosphere and turns it into fuel. They say it has the potential to save life on our planet.”

  • 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.”
