New count doubles the rocks in asteroid belt.

There are twice as many asteroids between Mars and Jupiter as previously believed, according to the latest study. But the probability of a stray one colliding with Earth remains negligible.

Edward Tedesco of US research company TerraSystems Inc.and Francois-Xavier Désert of the Astrophysical Laboratory in Grenoble, France, found that there are between 1.1 million and 1.9 million asteroids swarming round the ’main asteroid belt’1.

Research aimed at finding new diagnostic tests for BSE is gathering momentum at the Institute of Grassland and Environmental Research (IGER), where scientists have won a major research contract worth over £500,000 from the Department for Environment, Food and Rural Affairs (DEFRA).

`The new contract will help us expand our search for biochemical markers associated with BSE and scrapie,` said Professor Mike Theodorou, one of the leaders of the four-year programme. His colleague, Dr Gordon All

One of the most fascinating areas of astronomical research in recent years has been the search for other `Earths` circling Sun-like stars far beyond our Solar System.

In recent years nearly 100 planets have been discovered in orbits around other stars, but none of these `exoplanets` remotely resembles the Earth. However, according to the latest computer simulations by Barrie Jones and Nick Sleep (The Open University), millions of Earthlike worlds could be scattered throughout the Galaxy, ju

New VLT Discovery Pushes Back the Beginnings

Using the ESO Very Large Telescope (VLT), a team of astronomers from The Netherlands, Germany and the USA [1] have discovered the most distant group of galaxies ever seen, about 13.5 billion light-years away. The Photo shows the sky region near the power

Iron is vital for cells, because it catalyzes key enzyme reactions; it is also crucial for respiration, fixing atmospheric oxygen to hemoglobin in red blood cells. Iron deficiency can lead to severe anemia, with inadequate tissue oxygenation. An excess of iron is also toxic, as it facilitates the generation of free radicals that can attack the liver, heart and pancreas. This is the case in hereditary hemochromatosis, a genetic disorder which, in 80% of cases, is linked to a point mutation in the Hfe-

Whether it will compete for the title of a girl’s best friend remains to be seen but the element osmium can already challenge diamond in at least one respect: stiffness. According to a report published in the current issue of Physical Review Letters, osmium can withstand compression better than any known material. The results provide a potentially new lead in the search for superhard materials.
Diamond’s ability to resist scratches, dents and chipping–in short, its hardness–makes
