New research confirms that dogs were the first animal to form a domestic relationship with humans, dating back to the end of the last Ice Age almost 16,000 years ago.

An unusual hellscape of a planet found 34 light years from Earth has a deep ocean of molten magma surrounded by noxious, hot, rotten egg-type fumes. It just may be the most uninhabitable alien landscape we've ever come across.

We used to think that of our primate relatives, chimps were the more aggressive ape and bonobos were more peaceful. A recent study found that bonobos are just as antagonistic as chimps, but it's the females targeting males.

From the pressurized space suits to living in underground spaces, it's clear that living on Mars would cause irreversible biological changes to any humans living there, to the point that it may be impossible for them or their descendants to return to Earth. With bigger heads and lighter bodies, might we also end up looking like Martians?
