Greenhouse-gas emissions from human activities do not only cause rapid warming of the seas, but also ocean acidification at an unprecedented rate. Artificial carbon dioxide removal from the atmosphere has been proposed to reduce both risks to marine life. A new study based on computer calculations now shows that this strategy would not work if applied too late.

Solar-Active-Houses heat themselves using heat collectors and water tanks. However, no one had conducted an objective assessment of how efficiently they do so. Researchers put some of these solar houses to the test, identified where there was room for improvement and laid the scientific groundwork for this housing concept.

A metal-free alternative catalyst for fuel cells may be at hand. A team of chemists introduces a new approach that uses a molecular catalyst system instead of solid catalysts. Although molecular catalysts have been explored before, earlier examples were much less efficient than the traditional platinum catalyst.
