Submission + - Has the Mars rover sniffed methane? (nature.com)

GrimAndBearIt writes: NASA's Curiosity rover is poised to settle years of debate on the question of atmospheric methane on Mars, which would be a sign of microbial life. With parts per trillion sensitivity, it's not so much a question of whether the rover will be able to smell trace amounts of methane, but rather a question of how much.

NASA has announced that Grotzinger’s team will discuss atmospheric measurements at a briefing on 2 November. If the rover has detected methane at sufficiently high concentration, or exhibiting temporal variations of the kind that suggests microbial activity, then it will surely motivate a desire to identify and map the sources.

Submission + - Sea Chair Project harvests plastic from the oceans to create furniture (gizmag.com) 2

cylonlover writes: You may have heard about the huge floating islands of garbage swirling around in the middle of the Earth's oceans. Much of that waterlogged rubbish is made up of plastic and, like Electrolux with its concept vacuum cleaners, U.K.-based Studio Swine and Kieren Jones are looking to put that waste to good use. As part of an ambitious project, they’ve come up with a system to collect plastic debris and convert it into furniture. Rather than collecting plastic that washes ashore or is snagged as by-catch in fishing nets, the team hopes to one day go where the trash is, collect and convert it to something useful while still at sea. Sea Chair envisions adapting fishing boats into floating chair factories that trawl for plastic and put it into production on-board.
