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.
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.
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.
Journalist Sura Jeselsohn writes about a recent visit to the Weizmann Institute’s Clore Garden of Science. Long fascinated by America’s Biosphere project and the idea of self-contained systems, she was delighted to find the Ecosphere and its educational environment. She also praises the Clore Garden for its fun exhibits.
Please take a moment to revisit the Weizmann Institute's noteworthy research from 2014, and stay tuned in 2015 for still more amazing breakthroughs. We're looking forward to blowing your mind, changing your life, saving the world – or just making you stop, think, and wonder.
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.
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.
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.
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.”
