• Marine algae were key to the development of life 650 million years ago, according to new research. Geochemists studying the issue found traces of biomolecules that increased the quantity of algae in the oceans millions of years ago, which in turn transformed the food web. (BBC)

• And finally, researchers have found a way to weaken or strengthen specific memories in mice, with potential implications for humans dealing with cognitive problems or post-traumatic stress disorder. (The Guardian)
