Women who work night shifts may have a 60 percent greater risk of breast cancer. This finding may be due to the body?s response to light, according to researchers at the Fred Hutchison Cancer Research Center in Seattle.

A gland in the brain known as the pineal gland produces the hormone melatonin when the body is exposed to sunlight or artificial light. This production is disrupted when people are up at night with the lights on.

?Exposure to light at night may increase the risk of breast cancer by suppressing the normal nocturnal production of melatonin by the pineal gland which, in turn, could increase the release of estrogen by the ovaries,? the researchers say. Breast cancer is linked with production of the female hormone estrogen.

DNA tests that have been done on what is said to be Saint Luke?s body have produced evidence that it may really be the physician who followed the apostle Paul on his missionary journeys and wrote one of the gospels, as well as the New Testament book of Acts. Genetic analysis suggests that whoever is buried in his tomb came from Syria, which, according to historical records, was his birthplace.

Legends say that St. Luke came from Antioch, which in Roman times belonged to Syria, and died in Thebes, Greece, around 150 AD, at the age of 84. According to carbon dating, the body belongs to a person who died between 72 AD and 416 AD.

Archeologists in Iraq have uncovered a temple dedicated to the goddess Ishtar in the ancient city of Babylon, 56 miles south of Baghdad. Ishtar was the goddess of love in Babylonia and Assyria. Under various names, the cult of the mother goddess spread throughout the ancient Near East.

?Cuneiform inscriptions on the 25 artifacts found at the temple indicate that the building dates back to the old Babylonian era, and to the reign of King Hammurabi (1792-1750 BC) in particular,? according to a researcher at the Antiquities and Heritage Department.

The human race is likely to be wiped out by a doomsday virus before this millennium is over unless we set up colonies in space, Stephen Hawking warns. He says that biology, rather than physics, presents the biggest challenge to human survival.

?Although September 11 was horrible, it didn?t threaten the survival of the human race, like nuclear weapons do,? says Hawking, the Cambridge University scientist who may be the world?s most famous physicist. ?In the long term, I am more worried about biology. Nuclear weapons need large facilities, but genetic engineering can be done in a small lab. You can?t regulate every lab in the world. The danger is that either by accident or design, we create a virus that destroys us.
