An anonymous reader asks: "Like many readers, I find it necessary to leave my home PC running 24/7, for things like web or FTP servers, BitTorrent, or simply to make sure I don't miss any messages on IRC or my instant messaging client. It has been about 3 years since I built my current PC, and keeping it running all the time uses a lot of juice. With my next PC, I would like to do what I can to keep the power-consumption to a minimum, without sacrificing processing power or other features. What should I look for when choosing components for my PC, and what other ways are there to keep the power consumption down?"

MSNBC has up an article discussing the results of a Newsweek poll on faith and religion among members of the US populace. Given the straightforward question, 'Is evolution well-supported by evidence and widely accepted within the scientific community?', some 48% of Americans said 'No'. Furthermore, 34% of college graduates said they accept the Biblical story of creation as fact.
