Like sweet, tender romance?   Don't date a sand beetle.   Researchers at Uppsala University say what is good for one sex is not always good for the other sex and evolutionary conflicts between the two sexes cause characteristics and behaviors that are downright injurious to the opposite sex.

In both males and females in the animal world it is common – much more common that one might like to think – for one sex to evince characteristics and properties that are injurious to individuals of the other sex.

Roman artefacts which are nearly two thousand years old with similarities to ancient remains found at Pompeii in Italy will be examined at the Science and Technology Facilities Council’s ISIS neutron source in Oxfordshire this weekend.    Researchers hope to learn more about English heritage by discovering whether the items were imported from southern Italy, or manufactured using similar techniques in Britain.

Astronomers using the NASA Swift Satellite are tracking a spectacular comet as it closes in on Earth and sheds gas and dust from its vaporized ice.

A comet is a clump of frozen gases mixed with dust. These "dirty snowballs" cast off gas and dust whenever they venture near the sun. Comet Lulin, which is formally known as C/2007 N3, was discovered last year by astronomers at Taiwan's Lulin Observatory. The comet is now faintly visible from a dark site. Lulin will pass closest to Earth - 38 million miles, or about 160 times farther than the moon - on February 24.
