Researchers have uncovered chemical traces of a pigment, an important component of color, that once formed patterns in the feathers of fossilized birds. The pigment is one of the coloring agents responsible for brown eyes and dark hair in many modern species.  This discovery would have been one of the factors that determined the birds' color patterns, along with structural properties of the birds' feathers and other pigments they ingested as part of their diets. The discovery will help...

ESA's Integral gamma-ray observatory has spotted extremely hot matter just a millisecond before it plunges into the oblivion of a black hole. But is it really doomed? These unique observations suggest that some of the matter may be making a great escape. No one would want to be so close to a black hole. Just a few hundred kilometers away from its deadly surface, space is a maelstrom of particles and radiation. Vast storms of particles are falling to their doom at close to the speed of...

The Crab Nebula, one of our best-known and most stable neighbors in the winter sky, is shocking scientists with a propensity for fireworks"”gamma-ray flares set off by the most energetic particles ever traced to a specific astronomical object. The discovery, reported today by scientists working with two orbiting telescopes, is leading researchers to rethink their ideas of how cosmic particles are accelerated. "We were dumbfounded," said Roger Blandford, who directs the Kavli Institute...

Jets of particles streaming from black holes in far-away galaxies operate differently than previously thought, according to a study published today in Nature. The new study reveals that most of the jet's light"”gamma rays, the universe's most energetic form of light"”is created much farther from the black hole than expected and suggests a more complex shape for the jet. The research was led by scientists at the Kavli Institute for Particle Astrophysics and Cosmology, jointly...

WASHINGTON -- The United States is losing its lead in high-energy physics, a field of science it's dominated since the 1930s. Scientists say Europe is now in the vanguard of a worldwide search to discover the deepest secrets that Mother Nature hides in bits and pieces of atoms. At least 15 years, probably more, will pass before American physicists lead the pack again. Particle physics, as the field is called, lies at the heart of all modern science. Particle researchers explore the...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
