Mysterious Crater Widens to Antarctica

A new report of tiny beads of meteor impact glass strewn high in Antarctica's Transantarctic Mountains may expand a debris field to a tenth of Earth's surface -- despite no sign of the crater which spewed out the molten rock 800,000 years ago.

Transparent Computer Monitors? Engineers Make First 'Active Matrix' Display Using Nanowires

Engineers have created the first "active matrix" display using a new class of transparent transistors and circuits, a step toward realizing applications such as e-paper, flexible color monitors and "heads-up" displays in car windshields.

Shooting Star Shower Spotted on Mars

A shower of shooting stars has been recorded by instruments on Mars for the first time, astronomers say.

Meteors have been spotted before by the Mars rovers, but no device has ever detected a full shower until now.

United Kingdom astronomers predicted the event by tracking a comet's path near Mars, then comparing their forecast with Mars Global Surveyor (MGS) satellite data of the red planet's ionosphere - the upper reaches of atmosphere teeming with charged particles.

The Newcastle cybrids lived for three days
and the largest grew to contain 32 cells

Embryos containing both human and animal material have been created in Britain for the first time, a month before the House of Commons is to vote on new laws to regulate the controversial research.

A team at the University of Newcastle-upon-Tyne announced tonight that it had successfully generated "admixed embryos" by adding human DNA to empty cow eggs, in the first experiment of its kind in the UK.

Hypercubes Could Be Building Blocks of Nanocomputers

Multi-dimensional structures called hypercubes may act as the building blocks for tomorrow's nanocomputers - machines made of such tiny elements that they are dominated not by forces that we're familiar with every day, but by quantum properties.

Humans have more distinctive hearing than animals, study shows

Do humans hear better than animals? It is known that various species of land and water-based living creatures are capable of hearing some lower and higher frequencies than humans are capable of detecting. However, scientists from the Hebrew University of Jerusalem and elsewhere have now for the first time demonstrated how the reactions of single neurons give humans the capability of detecting fine differences in frequencies better than animals.

Mysterious Egyptian Glass Formed by Meteorite Strike, Study Says

Strange specimens of natural glass found in the Egyptian desert are products of a meteorite slamming into Earth between 100,000 and 200,000 years ago, scientists have concluded.

Ancient Gold Necklace Discovered in Peru

WASHINGTON - The earliest known gold jewelry made in the Americas has been discovered in southern Peru. The gold necklace, made nearly 4,000 years ago, was found in a burial site near Lake Titicaca, researchers report in Tuesday's issue of Proceedings of the National Academy of Sciences.

Scientists set out to unlock secrets of Stonehenge

Archaeologists set out on Monday to unlock one of the secrets of Stonehenge, the majestic monument in southern England -- when were the first standing stones placed at the ancient religious site?

The concentric stone circles that make up Stonehenge, 80 miles southwest of London on the sweep of Salisbury Plain, consist of giant sandstone blocks or sarsens and smaller bluestones -- volcanic rock of a blueish tint with white flecks.

Stonehenge experts Tim Darvill and Geoff Wainwright will use modern carbon dating techniques and analysis of soil pollen and sea shells to work out when the stones were set up, in the first archaeological dig at the World Heritage site since 1964.

For The Paper Trail Of Life On Mars Or Other Planets, Find Cellulose

Looking for evidence of life on Mars or other planets? Finding cellulose microfibers would be the next best thing to a close encounter, according to new research from the University of North Carolina at Chapel Hill.

The cover story for the April issue of the journal Astrobiology, the new research also pushes back the earliest direct evidence of biological material on Earth by about 200 million years.
