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.

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.

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.

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.

Striga – aka witchweed – infests more than 405 million acres of sub-Saharan land, causing African farmers to lose up to 100% of their crops, resulting in widespread hunger and financial hardship. StrigAway, an herbicide developed by a group that includes the Weizmann Institute, keeps the weed from attaching to the plant – and improves life for around 100 million people.

Prof. David Cahen, head of the Weizmann Institute's Alternative Energy Research Initiative, and colleague Prof. Leeor Kronik discuss humankind's energy problem – specifically, that we cannot keep using energy as we do today – and potential solutions, such as use of highly efficient solar power. The event was held at The Gregory School in Tucson.
