The human knee is a triumph of design. The joint, which evolved fairly rapidly from our common ancestor with the chimpanzee to accommodate our bipedalism, likely contributed to our success as a species.

Often considered desolate, remote, unalterable places, the high seas are, in fact, hotbeds of activity for both people and wildlife.

A team of Clemson University College of Science researchers, in collaboration with international colleagues, has reported the first definitive detection of a relativistic jet emerging from two colliding galaxies -- in essence, the first photographic proof that merging galaxies can produce jets of charged particles that travel at nearly the speed of light.

When a massive star in a distant galaxy collapses, forming a black hole, two giant jets of light-emitting plasma shoot from its core.

Unlike humans, sea turtles and other reptiles like crocodiles do not have sex chromosomes. Their sex is defined during development by the incubation environment.

The origin of turtles is among the most debated topics in evolutionary biology. In a recently published study by Senckenberg scientist Ingmar Werneburg, in cooperation with an international research team, refutes existing hypotheses and sheds a new light on the evolution of the skull architecture.
