Researchers have found neurons in nematode worms that help them learn when to prioritise mating over eating. This does not necessarily have anything to do with humans.

A large team of scientists have published a paper about a strange star, KIC 8462852, which has an unusual pattern of dimming and brightening. One possible - though remote - explanation they have proposed is a Dyson's sphere.

Thanks again to some zircon cyrstals, researchers may have found evidence of ancient microorganisms that lived at least 4.1 billion years ago. If confirmed, the discovery suggests that life originated on Earth 300 million years earlier than previously thought.
