Quirks and Quarks

There's been a growing movement to develop new technologies to replace at least some of the animals used in scientific research. Researchers across Canada are working to create these tools, to usher in a new animal-free era for medical science.

On their mission around the moon, Jeremy Hansen and his crewmates will become the only four people on Earth to ever lay eyes on the entire far side of the moon. Since joining the space program, the Artemis astronauts have been undergoing intensive geological training to help train their eyes to look for lunar features that satellites can't pick up.

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.
