Submission + - British Bomb Scare Prompts U.S. Camera Call (thehill.com)

mattnyc99 writes: Senator Joseph Lieberman is riding the successful capture of several terror suspects by British authorities in an alleged car bomb plot this weekend as ammunition to call for wider use of surveillance cameras in the U.S. It turns out the U.K. is already testing new flying police drones equipped with closed-circuit TV cameras. So is constant urban surveillance on the horizon? Or is Britain just ready to foil the next threat even faster, with better tech than we have back in the States?

Submission + - Death rates will rise because of global warming (medicalnewstoday.com)

brian0918 writes: Harvard researchers analyzing city-specific weather data related to the deaths of more than 6.5 million people in 50 US cities between 1989 and 2000 have concluded that while global warming will cause more deaths in summer because of higher temperatures, these will not be offset by fewer deaths in milder winters. According to them, 'central heating, which constitutes an important adaptive mechanism against cold, is almost universal in the US, and this may explain why the US population seemed fully acclimatised to cold. Making air conditioning universally available may reduce heat-related mortality but would, on the other hand, have a perverse effect by enhancing global warming through carbon dioxide emissions from electricity consumption.'
