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.

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.

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.

Dr. Ron Milo and a team that included U.S. scientists created a tool to analyze the environmental costs of agriculture, with the goal of determining which types of animal-based food one should eat, environmentally speaking. In the most comprehensive study of its kind, they came up with answers both expected and surprising.

Update from the Weizmann Institute: Prof. Ilan Koren's research suggests that human activities may be producing larger, higher clouds with greater greenhouse effect. Using data from NASA's CERES and elsewhere, his findings indicate that, in pre-industrial times, there was less cloud cover over areas of pristine ocean than today.

Weizmann's Prof. Jacob Karni developed a way to convert carbon dioxide (CO2) using concentrated solar energy. An Israeli-Australian venture will use the technology to reduce CO2 emissions from burning brown coal, which is widely available in southeastern Australia.

Three research updates from the Weizmann Institute of Science: hope for stroke victims; turning off stress; and using old paper to track human-made pollution.

Weizmann scientists have found a forest that directly absorbs and retains heat, thus complicating the idea that forests help cool the earth by removing CO2.
