Science that old work pony has its days. When you hear someone tell you that science has got it all right and the game is up well think again. I hate to think how many times some fool has stepped up to the crease with an absolute definition only to be bowled out on the next ball (Barry William eat your cricket heart out!)  Science not that perfect.- Have a read.
Hawking cracks black hole paradox
New Scientist 19:00 14 July 04  - Link
"After nearly 30 years of arguing that a black hole destroys everything that falls into it, Stephen Hawking is saying he was wrong. It seems that black holes may after all allow information within them to escape. Hawking will present his latest finding at a conference in Ireland next week."

"The about-turn might cost Hawking, a physicist at the University of Cambridge, an encyclopaedia because of a bet he made in 1997. More importantly, it might solve one of the long-standing puzzles in modern physics, known as the black hole information paradox."

"It was Hawking's own work that created the paradox. In 1976, he calculated that once a black hole forms, it starts losing mass by radiating energy. This "Hawking radiation" contains no information about the matter inside the black hole and once the black hole evaporates, all information is lost."
New twist on out-of-Africa theoryJudy Skatssoon
U.S. researcher Professor Alan Templeton of Washington University, St Louis, debunks the prevailing version of the out-of-Africa hypothesis, which says early humans migrated from Africa and wiped out Eurasian populations.

Instead, they bred, he told the Genetics Society of Australia's annual conference in Melbourne this week. Templeton said his evidence didn't support the so-called replacement theory in which African hominids caused the extinction of other Homo species.

But Templeton said this extinction never happened and a combination of movement and interbreeding meant diversification of races didn't occur.

"We really have to abandon the idea of race. It actually does not reflect the genetic differences we can now measure in an objective fashion."
