More bad news for dinosaurs: Chicxulub meteorite impact triggered global volcanic eruptions on the ocean floor

Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.

Curious Kids: Why is the Earth round?

Imagine the Earth pulling everything it is made up of, all of its mass, towards its centre. This happens evenly all over the Earth, causing it to take on a round shape.

Antimatter breakthrough sheds light on matter’s shadowy twin

One of the great mysteries of the universe is why there is so much more matter than antimatter. Now a new experiment is helping us understand the nature of antimatter better than ever before.
