As early as six million years ago, apparently close to the beginning of the human lineage, an ancestral species had already developed the transforming ability for upright walking, scientists reported on Thursday.

A new, more detailed analysis of a fossil thigh bone found eight years ago in Kenya yielded strong evidence that the species Orrorin tugensis stood and walked on its hind... ]]> feeds@yuku.com (Bayou Halfling) http://babelcon.yuku.com/topic/1071 Sat, 22 Mar 2008 09:39:57 GMT <![CDATA[ Antarctic Voyage Returns with Animals New To Science ]]> http://babelcon.yuku.com/topic/1070/t/Antarctic-Voyage-Returns-with-Animals-New-To-Science.html Antarctic Voyage Returns with Animals New To Science

Scientists and crew of New Zealand's biggest scientific voyage in the Antarctic waters of its Ross Sea dependency have returned with a treasure trove of new fish and other organisms.

A "dry fog" that dimmed the sun's rays in A.D. 536, and plunged half the world into a famine-inducing chill, was triggered by the eruption of a super-volcano, a new study says. The cause of the sixth-century global dimming has long been a matter of debate, but a team of international researchers recently discovered acidic sulphate molecules, which are signs of an eruption, in... ]]> feeds@yuku.com (Bayou Halfling) http://babelcon.yuku.com/topic/1069 Sat, 22 Mar 2008 09:39:04 GMT <![CDATA[ Flipping Particle Could Explain Missing Antimatter ]]> http://babelcon.yuku.com/topic/1066/t/Flipping-Particle-Could-Explain-Missing-Antimatter.html Flipping Particle Could Explain Missing Antimatter

It is one the biggest mysteries in physics - where did all the antimatter go? Now a team of physicists claims to have found the first ever hint of an answer in experimental data. The findings could signal a major crack in the standard model, the theoretical edifice that describes nature's fundamental particles and forces.

The dispute over the "Hobbits" of Flores continues, unabated. The bones and a single skull of these "little people" are believed to be remains of a separate species of the human family that lived about 18,000 years ago on an island in Indonesia, as the scientists who made the sensational discovery concluded in 2004.

A salamander's limbs are smaller and a bit slimier than those of most people, but otherwise they are not that different from their human counterparts. The salamander limb is encased in skin, and inside it is composed of a bony skeleton, muscles, ligaments, tendons, nerves and blood vessels. A loose arrangement of cells called fibroblasts holds all these internal tissues together and gives... ]]> feeds@yuku.com (Bayou Halfling) http://babelcon.yuku.com/topic/1064 Sat, 22 Mar 2008 09:35:38 GMT <![CDATA[ Math Trek: Spoil-Proofing Elections ]]> http://babelcon.yuku.com/topic/1063/t/Math-Trek-Spoil-Proofing-Elections.html Math Trek: Spoil-Proofing Elections

When Ralph Nader recently announced he was entering the 2008 presidential race, many Democrats groaned. It was his fault, they say, that George Bush defeated Al Gore in 2000. Mathematicians offer a different perspective. The problem, they say, doesn't lie with Nader or with the Democrats. It lies with our voting system.

One of Saturn's moons once harbored a liquid ocean beneath its icy surface, scientists say. Tethys is a mid-sized satellite with a density close to that of pure ice. But a large valley system visible today must have formed when the crust was being heated and under great strain. Tidal heating, followed by cooling which froze Tethys' ocean, could have formed the giant Ithaca Chasma rift.

Nearly all of today's Native Americans in North, Central and South America can trace part of their ancestry to six women whose descendants immigrated around 20,000 years ago, a DNA study suggests.

Those women left a particular DNA legacy that persists to today in about 95 percent of Native Americans, researchers said.

Large volumes of water ice have been detected below Mars' surface, far from the planet's polar ice caps, scientists have said. The Sharad radar experiment, on Nasa's Mars Reconnaissance Orbiter (MRO) spacecraft made the discovery in Mars' mid-northern latitudes.

Humans were once as hairy as the next ape. Fact is, we still are. "Humans don't actually have any fewer hairs than a chimpanzee or a gorilla," says Christophe Soligo, a biological anthropologist at the Natural History Museum in London. "The difference is simply that over most of our human bodies, the hair has become so short and flimsy as to be virtually invisible.

No other 310-mile-wide ice ball in the solar system is attracting quite the attention as Enceladus, a moon of Saturn.

NASA's Cassini spacecraft had a deliberate near-miss with Enceladus on Wednesday afternoon, passing about 30 miles above its surface at a speed of more than 32,000 miles per hour.

A pair of mysterious meteorites discovered in Antarctica is baffling scientists who are struggling to determine the origin of the space rocks.

The meteorites, dubbed GRA 06128 and GRA 06129, were found in the "Graves Nunataks" region of Antarctica in 2006. The rocks were oddly rusty and salty and smelled like rotten eggs, their discoverers said.
