Earth's water formed close to home

A new study claims most of Earth's water didn't originate in the frozen outer reaches of the solar system, but came from the asteroid belt.

Earliest Americans Arrived in Waves, DNA Study Finds

North and South America were first populated by three waves of migrants from Siberia rather than just a single migration, say researchers who have studied the whole genomes of Native Americans in South America and Canada.

M-Theory and the Higgs boson

The discovery of a potential Higgs boson particle plays a crucial role in super-symmetry - just one more of the ingredients needed to provide evidence of the M-Theory of strings.

Australopithecus sediba ate bark

Australopithecus sediba, a short, gangly South African species from two million years ago, targeted trees, bushes and fruits for its diet, chomping on harder foods than other known early hominids, or human ancestors. Virtually all others that have been tested from Africa—including Paranthropus boisei, dubbed “Nutcracker Man” thanks to its massive jaws and teeth—focused more on grasses and sedges.

Could Neanderthals have painted?

New estimates on the date of ancient European cave paintings raise the possibility that Neanderthal people might have made them.

Feathered dinosaur fossil found in Germany

German researchers say they have discovered a fossil of a feathered hatchling that may be the earliest evidence of a plumed, meat-eating dinosaur that was not closely related to birds.  The fossil is believed to belong to a young land-based dinosaur from the Late Jurassic period, some 170 million years ago.

Scientists find best hint of elusive Higgs particle

Scientists have discovered a sub-atomic particle they believe is crucial in the formation of the universe.  The Higgs boson, otherwise known as the God particle, is thought to give all other particles in the universe their mass.

Long-sought Higgs particle probably found

Scientists at the European Laboratory for Particle Physics, CERN, near Geneva announced on Wednesday that a particle fitting the correct description had been found, though there remains the unlikely possibility it is a misidentification.
