New NASA Mars Rovers Dwarf Sojourner - ABC  The new rovers weigh 384 pounds apiece compared to petite Sojourner's 24 pounds, like a pair of golf carts next to a microwave oven. "They are certainly extremely complicated, extremely powerful and extremely sophisticated robots," said Steve Squyres, the principal scientist on the $820 million double mission. Spirit is scheduled to land on Mars late Saturday. Opportunity should follow on Jan. 24, landing on the opposite side of the planet. They are supposed to be in operation on the Mars surface for 90 days. "We have effectively merged the capability of the Pathfinder lander and the Sojourner rover into one larger rover." "In a sense, we have taken the Pathfinder lander and put it on wheels. If you think about that, you'd say 'How did they make it so small?'" he added.
Wind Catching On  - BBC  Left: The number of wind farms has been steadily increasing around the world.  A recent study by the Department of Energy labeled wind the "fastest-growing energy source in the world." In the three year period from 2000 to 2003, wind power capacity increased a whopping 159 percent in Europe and 87 percent in the United States, according to Standard and Poor's Ratings Services. Nowhere is this shift more pronounced than in Europe. Development of a huge "wind farm" off the English and Welsh coasts took a giant step forward earlier this month when 15 groups bid successfully for the right to participate in the project.

Arctic Siberia

'New World' link to Arctic find  - BBC  Humans occupied the freezing lands high above the Arctic Circle during the last Ice Age, say Russian archaeologists. New Stone Age artefacts from Yana in northern Siberia have pushed back the human presence in the Arctic by around 16,000 years, surprising many experts. The finds suggest humans may have been hunting big game animals in the region by around 30,000 years ago. "This site shows that people adapted to this harsh, high-latitude, Late Pleistocene environment much earlier than previously thought," the authors write in Science. "It's about as far north as you can get; it's pretty neat."
