Submission + - What Medical Tests Should Teach Us about the NSA Surveillance Program

Davak writes: In many ways finding the small amount of terrorists within the United States is like screening a population of people for a rare disease. A physician explains why collecting excessive data is actually dangerous. Each time a test is run, the number of people incorrectly identified quickly dwarfs the correct matches. Just like in medicine, being incorrectly labelled has serious consequences.

Submission + - 4,000 MPH@1G Hyperloop Transport Dream Approaches Reality 2

Freshly Exhumed writes: Elon Musk's dream of a hyperloop transport system seems to be closer to reality than he anticipated. Hyperloop transportation, referred to by Musk as a "cross between a Concorde, a railgun, and an air hockey table", is a tubular pneumatic transport system with the theoretical capability of carrying passengers from New York to L.A. in about 30 minutes at velocities near 4,000 miles per hour, while maintaining a near-continuous G force of 1. Colorado-based company ET3 is planning to build and test its own version of such a hyperloop system, Yahoo reports.

Comment NASA unable to reduce launch costs... (Score 1) 394

"Despite decades of putting rockets into space, the agency has never managed to make any real reductions in launch costs in that time." Thats no surprise.

Yeah, thats the ticket.

Water Vapor Causing Climate Warming 434

karvind writes "According to BBC, new studies suggest that water vapor rather than carbon dioxide in the atmosphere is the main reason why Europe's climate is warming. The scientists say that rising temperatures caused by greenhouse gases are increasing humidity, which in turn amplifies the temperature rise. This is potentially a positive feedback mechanism which could increase the impact of greenhouse gases such as CO2. Even though 2005 will probably be warmest year, climatologists still differ in opinion"

Climatologists Wager on Global Warming 591

coflow writes "The Guardian is carrying a story about a $10,000 bet that a pair of Russian scientists have entered with British climate expert James Annan. According to the article, the Russians believe the world will be cooler in 10 years. "If the temperature drops Dr Annan will stump up the $10,000 (now equivalent to about £5,800) in 2018. If the Earth continues to warm, the money will go the other way.""
