Ancient 'giraffes' sported thick helmets for headbutting

00:33 A headbashing relative gives insights into giraffe evolution

How the giraffe got its long neck is a longstanding question in science. One possibility is that giraffes evolved longer necks for sexual competition, with males engaging in violent neck-swinging fights. Now, a team have described fossils of an ancient giraffoid species with a thick headpiece adapted for fighting, which could add weight to this hypothesis.

10:34 An emergency fix gets MAVEN back on track

Earlier this year, NASA’s MAVEN spacecraft, which has been orbiting Mars since 2014, developed some serious equipment issues that prevented it from keeping its correct orientation in space. In a race against time, a team on Earth fixed the problem by developing a system that allowed the spacecraft to navigate by the stars.

NASA’s Perseverance rover has arrived at an ancient Martian river delta where it will spend the next few months exploring, while scientists assess where to drill and extract rock samples. It’s thought that rocks from this region have the best chance of containing evidence of Martian life, and plans are being developed to return them to Earth in the future.
