Strange Orbits
Like toy cars chasing each other on a looped racetrack, three stars can, in principle, trace out a figure-eight orbit in space. This newly discovered, mathematically surprising pattern of motion arises from the force of gravity acting on three bodies of equal mass. Their movements are timed so that each body in turn passes between […]

Tapeworms tell tales of deeper human past
A new analysis of tapeworm history suggests that people have been wrong about where we picked up pests: It was not domestication of cattle and pigs but increased meat eating in Africa.
