A 30-mile maze canyons in Antarctica was carved out of bedrock by the catastrophic draining of subglacial lakes during global warming between 12 million and 14 million years ago, according to university researchers who warn a similar event today could have serious environmental consequences. Although scientists have previously theorized that the Labyrinth region in southern Victoria Land was created by water released from lakes that had formed under glaciers, researchers at Syracuse University and Boston University say they found geological evidence to bracket the timing of the last major flooding and link it to a global warming trend at the...

Scientists went to work digging for fossils at La Brea Tar Pits, digging the tooth of a 5-foot (1.5-meter) dire wolf and the toe of a sabertooth tiger from the sticky prehistoric asphalt near downtown Los Angeles. About 10,000 years before the arrival of mammoth traffic jams in the second-largest U.S. city, the two beasts likely got stuck in the goo while hunting a camel, horse or ground sloth, said John Harris, chief curator and head of vertebrate studies at the Natural History Museum of Los Angeles County, which oversees the site. ''It's one of the, if not the, richest...

Thousands of barges could save Europe from deep freeze By BJS Created 02/06/2006 - 13:47 It is ironic that one consequence of global warming is that Europe might plunge into a deep freeze. This possibility stimulated an unusual research project at the University of Alberta.Dr. Peter Flynn, the Poole Chair in Management for Engineers in the U of A Department of Mechanical Engineering, has studied whether down-welling ocean currents can carry more dissolved carbon into the deep ocean. He learned they can't, but in the course of this research he found some evidence that the ocean currents that bring...

It might sound preposterous, like astrology, to suggest that galactic events help determine when North America is or isn't buried under immense sheets of ice taller than skyscrapers. But new research suggests the coming and going of major ice ages might result partly from our solar system's passage through immense, snakelike clouds of exploding stars in the Milky Way galaxy. Resembling the curved contrails of a whirling Fourth of July pinwheel, the Milky Way's spiral arms are clouds of stars rich in supernovas, or exploding stars. Supernovas emit showers of charged particles called cosmic rays. Theorists have proposed that when...

'Lost river' could rewrite history books February 19 2002 at 08:33AM Madras India, - The discovery of an ancient city on the seabed off India's western coast has scientists salivating at the prospect of a fundamental rewrite in the chronology of ancient human society. Preliminary tests have suggested the site in the Gulf of Cambay off Gujarat state could date as far back as 7 500 BC, several thousand years older than what were previously known to be the first significant urban settlements. The discovery was made purely by chance last year as oceanographers from the National Institute of ...

In May 2001, engineer Paulina Zelitzky, President, ADC Corporation, Victoria, B. C., Canada and Havana, Cuba, announced the discovery of megalithic structures 2,200 feet down at the western tip of Cuba. November 19, 2001 Havana, Cuba - The story about a possible megalithic site half a mile down off the western tip of Cuba first broke this past May when a Reuters News Service reporter interviewed the deep ocean engineer who first reported unusual sidescan sonar of the discovery. Her name is Paulina Zelitsky. Ms. Zelitsky was born in Poland, studied engineering in the Soviet Union, was assigned to ...

Remains of an ancient civilization discovered in the depths of the Northern sea While some scientists spend all their time and efforts in search of Atlantis, others have already discovered remains of an ancient civilization that had existed on the same territory as present-day Northern sea. With the help of modern technology, archaeologists were able to get a better glimpse of the ancient world. Approximately 10 000 years ago the entire bottom of the Northern sea had been a blossoming valley, inhabited by ancestors of modern-day Europeans. Scientists from the Birmingham University were able to reach such conclusion after reconstructing...

BARNWELL, S.C., June 24 - On a hillside by the Savannah River, under tall oaks bearded with Spanish moss, an archaeologist and a graduate student crouched in the humid depths of a trench. They had reason to think they were in the presence of a breathtaking discovery. Or at the least, they were on to something more than 20,000 years old that would throw American archaeology into further turmoil over its most contentious issue: when did people first reach America, and who were they?

As elusive as the Cheshire Cat, the first people to arrive in the Americas have tended to appear and vanish with each new twist in the archaeological record. The latest disappearing act may be taking place on page 501, where new evidence, some claim, casts another shadow over a once-cherished idea: that Asian big-game hunters crossed the Bering Land Bridge to give rise to the Clovis people, who were considered the first Americans. New dates show that a crucial Siberian site, thought to be a way station along the Bering road, wasn't occupied until after the Clovis had begun killing...

<p>Humanity's first steps out of Africa along a path that led ultimately to dominion over the earth are subject to intense scientific debate. So is the role played by the Neandertals who roamed across Europe for 100,000 years before quietly disappearing. The two issues may well be related, and a University of Tennessee anthropologist reports statistical evidence that Neandertals and emerging modern humans likely interbred and evolved together.</p>

Big chill killed off the Neanderthals 19:00 21 January 04 It is possibly the longest-running murder mystery of them all. What, or even who, killed humankind's nearest relatives, the Neanderthals who once roamed Europe before dying out almost 30,000 years ago? Suspects have ranged from the climate to humans themselves, and the mystery has deeply divided experts. Now 30 scientists have come together to publish the most definitive answer yet to this enigma. They say Neanderthals simply did not have the technological know-how to survive the increasingly harsh winters. And intriguingly, rather than being Neanderthal killers, the original human settlers...

<p>Washington — A people who may have been ancestors of the first Americans lived in Arctic Siberia, enduring one of the most unforgiving environments on Earth at the height of the Ice Age, according to researchers who discovered the oldest evidence yet of humans living near the frigid gateway to the New World. Russian scientists uncovered a 30,000-year-old site where ancient hunters lived on the Yana River in Siberia, some 300 miles north of the Arctic Circle and not far from the Bering land bridge that then connected Asia with North America.</p>
