Every now and again, dozens or even hundreds of perfectly healthy looking whales strand themselves on a beach. Scientists have a few theories on why they do this. 

Samples from asteroids have helped build a theory of the origin of complex molecules and how they made it to Earth.

Fresh Australian dietary guidelines are due next year, and they’ll likely focus on the health of the planet as well as people.

Small chemical groups inserted or removed from around DNA may affect gene expression and so be a way to control genetic blood disorders such as sickle cell anaemia and beta thalassemia.

So considering they're all around us, how can we minimise our exposure to tiny plastic fragments without resorting to living in a cave?

A 100-yr flood is now a more regular occurrence in the German town of Passau, bringing widespread destruction, another local impact of a planet getting hotter.
