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.

Exploding Star And Rare View Of Early Stages Of A Supernova

The latest image from the NASA/ESA Hubble Space Telescope reveals a sharp view of the spiral galaxy NGC 2397. This image also shows a rare Hubble view of the early stages of a supernova - SN 2006bc, discovered in March 2006.

NGC 2397, pictured in this image from Hubble, is a classic spiral galaxy with long prominent dust lanes along the edges of its arms, seen as dark patches and streaks silhouetted against the starlight. Hubble's exquisite resolution allows the study of individual stars in nearby galaxies.

Newly Discovered Galaxy Cluster In Early Stage Of Formation Is Farthest Away Ever Identified

UC Irvine scientists have discovered a cluster of galaxies in a very early stage of formation that is 11.4 billion light years from Earth - the farthest of its kind ever to be detected. These galaxies are so distant that the universe was in its infancy when their light was emitted.

The galaxy proto-cluster, named LBG-2377, is giving scientists an unprecedented look at galaxy formation and how the universe has evolved. Before this discovery, the farthest known event like this was approximately 9 billion light years away.

Two Yellow Supergiant Eclipsing Binary Systems Discovered: First Of Their Kind Ever Found

Astronomers have spied a faraway star system that is so unusual, it was one of a kind -- until its discovery helped them pinpoint a second one that was much closer to home. In a paper published in a recent issue of the Astrophysical Journal Letters, Ohio State University astronomers and their colleagues suggest that these star systems are the progenitors of a rare type of supernova.

Ohio State University astronomers and their colleagues have discovered a new type of star system, one that may be the progenitor of a rare type of supernova. The star system is called a "yellow supergiant eclipsing binary" -- it contains two very bright, massive yellow stars that are very closely orbiting each other. In fact, the stars are so close together that a large amount of stellar material is shared between them, so that the shape of the system resembles a peanut.
