Mars Images Reveal Evidence of Ancient Lakes 128

Matt_dk writes "Spectacular satellite images suggest that Mars was warm enough to sustain lakes three billion years ago, a period that was previously thought to be too cold and arid to sustain water on the surface, according to research published today in the journal Geology. Earlier research had suggested that Mars had a warm and wet early history but that between 4 billion and 3.8 billion years ago, before the Hesperian Epoch, the planet lost most of its atmosphere and became cold and dry. In the new study, the researchers analysed detailed images from NASA’s Mars Reconnaissance Orbiter, which is currently circling the red planet, and concluded that there were later episodes where Mars experienced warm and wet periods."

IT Workers To Get Fewer Perks, No Free Coffee 620

dasButcher writes "While the economy is showing signs of recovery and tech stocks posted double- and triple-digit gains in 2009, IT workers are facing a less hospitable workplace in the coming year. Many employers say they're going to continue trimming budgets, particularly in human resources. Rather than giving up head count, they're planning to trim 401k contributions, eliminate bonuses, curtail travel and, dare we say, shut off the free coffee (it wasn't that good anyway)."

New Pi Computation Record Using a Desktop PC 204

from the more-digits-than-you dept.
hint3 writes "Fabrice Bellard has calculated Pi to about 2.7 trillion decimal digits, besting the previous record by over 120 billion digits. While the improvement may seem small, it is an outstanding achievement because only a single desktop PC, costing less than $3,000, was used — instead of a multi-million dollar supercomputer as in the previous records."
