Science & Technology
Science has always struggled to sift crackpot ideas from genuine maverick genius. If it were just a matter of combining unambiguous data with flawless theories, the task would be quite simple. Unfortunately, says Harry Collins, science is an all-too-human activity, and heroes and villains come in every possible guise.
In 1985, David Deutsch turned physics upside down by describing a universal quantum computer, pioneering the field of quantum information science. He explains to Amanda Gefter how this relates to notions of truth and reality in our universe - and even outside it
Psst! Want 50,000 free DVDs? The US National Science Teachers Association didn't, even though the DVDs in question were of An Inconvenient Truth, the climate change movie that is required viewing for all children in Norway and Sweden.
Why not? Because according to Laurie David, one of the film's producers, the NSTA has accepted millions of dollars from oil firms, including Exxon Mobil and Shell. The NSTA has even promoted oil companies' "special interests and implicit endorsements", David said in the The Washington Post on 26 November.

"Soon a millennium will end. With it will pass four billion years of evolutionary exuberance. Yes, some species will survive, particularly the smaller, tenacious ones living in places far too dry and cold for us to farm or graze. Yet we must face the fact that the Cenozoic, the Age of Mammals which has been in retreat since the catastrophic extinctions of the late Pleistocene is over, and that the Anthropozoic or Catastrophozoic has begun." --Michael Soul� (1996)

This satellite file photo shows gullies on the walls of a meteor crater in the Newton Basin on Mars. Photos of other gullies on the planet suggest water may have flowed through them in the past decade.(NASA, Jet Propulsion Laboratories/Associated Press)
A new study of photographs taken from orbit suggest water flowed on Mars as recently as a few years ago, raising the possibility the planet could support life.
The images, taken from aboard a satellite, don't show water, however. Instead, they show recent changes in surface features that might have been made from the flow of liquid water.
Scientists have found evidence that the seeds of life may indeed have fallen from the sky.
Analysis of a meteorite that fell onto the frozen Tagish Lake in Canada in 2000 has shown the space rock to be riddled with organic material that is at least as old as the solar system itself. Researchers speculate that this kind of matter could have played a vital role in the development of early life on Earth.

- Rock which hit lake is oldest object ever found - Tests reveal fragment created before solar system
As lumps of rock go it looks much like any other, unexceptional despite the deep red of its cool, smooth surface. The pieces range in size from pea-sized lumps to larger fist-sized chunks. But today, scientists will announce this is no ordinary stone. Prised from a frozen lake in northern Canada, it has become a prime candidate for the oldest known object on Earth.

A computer in antiquity would seem to be an anachronism, like Athena ordering takeout on her cellphone.
But a century ago, pieces of a strange mechanism with bronze gears and dials were recovered from an ancient shipwreck off the coast of Greece. Historians of science concluded that this was an instrument that calculated and illustrated astronomical information, particularly phases of the Moon and planetary motions, in the second century B.C.

London- Humans must colonize planets in other solar systems traveling there using "Star Trek"-style propulsion or face extinction, renowned British cosmologist Stephen Hawking said on Thursday.
Referring to complex theories and the speed of light, Hawking, the wheel-chair bound Cambridge University physicist, told BBC radio that theoretical advances could revolutionize the velocity of space travel and make such colonies possible.
"Sooner or later disasters such as an asteroid collision or a nuclear war could wipe us all out," said Professor Hawking, who was crippled by a muscle disease at the age of 21 and who speaks through a computerized voice synthesizer.
