Scientists have discovered an elusive, mutated gene named for the Greek goddess, Aphrodite Kallipygos, that causes certain sheep to have unusually big and muscular bottoms. They hope the genetic mutation will illuminate how muscle and fat are deposited in these animals and possibly in humans.

The discovery is especially exciting, said the researchers, because the unusual gene has evaded all the traditional means of detection for nearly a decade. In fact, the gene appears to represent one of

Entomologists have discovered that there are far more insects flying around above our heads than previously thought. Speaking at the Royal Entomological Society’s national meeting Entomology 2002, which will take place at Cardiff University on 12–13 September 2002, Dr Jason Chapman will say that in a typical summer month, around 3.5 billion insects fly over a square kilometre. This equates to one tonne of insects flying over Hyde Park in London, or Trelai Park in Cardiff, every four weeks in summer.

In the search for a nonpolluting energy source, hydrogen is often cited as a potential source of unlimited clean power. But hydrogen is only as clean as the process used to make it. Currently, most hydrogen is made from fossil fuels like natural gas using multi-step and high-temperature processes.

Now, chemical engineers at the University of Wisconsin-Madison have developed a new process that produces hydrogen fuel from plants. This source of hydrogen is non-toxic, non-flammable and can be

The world’s most sensitive Gamma Ray telescopes are being inaugurated in Namibia (in Southwest Africa) on September 3rd. The High Energy Stereoscopic System (H.E.S.S.), a European/African collaboration in which the UK is a partner, will look for Gamma Rays produced by the most energetic particles in the Universe. The array initially consists of four telescopes, the first of which will become operational next week. This one telescope alone is more sensitive than any other existing ground-based array o

Advance Should Speed Semiconductor Industry Search

Researchers from the Commerce Department’s National Institute of Standards and Technology (NIST) reported today they have developed methods for characterizing key structural features of porous films being eyed as insulators for the ultrathin metal wires that will connect millions of devices on future microprocessors and increase processor speed. The advance, reported today at the American Chemical Society’s national meeting

A comprehensive examination of how the unique head and snout affects maneuverability and the role of its electrosensory function for seeking food along the ocean floor

Why the peculiar head shape of the hammerhead shark developed as it did has been the subject of much speculation. The dorso-ventrally compressed and laterally expanded pre-branchial head is an unmistakable diagnostic feature of the sphyrnid sharks. This unique head shape has been termed the cephalofoil in recognition of
