Submission + - SPAM: Satellite glitch rekindles GPS concerns

coondoggie writes: "News today that Air Force is investigating signal problems with its latest Global Positioning System satellite are likely to rekindle the flames of a congressional report last month that said the current GPS coverage may not be so ubiquitous in the future. The Air Force stated that routine early orbit checkout procedures determined that the signals from the Lockheed-built GPS IIR-2 (M), which was launched in March, were inconsistent with the performance of other GPS IIR-M satellites. The Air Force said it has identified several parameters in the GPS IIR-20 (M)'s navigation message that can be corrected to bring the satellite into compliance with current GPS Performance Standards.

Submission + - Marijuana smoke damages DNA (examiner.com) 8

It may be a lame april fools joke, but in the long term I wouldn't be surprised if stuff like this starts to happen. There are already a lot of news organizations that put out updates via Twitter. 140 characters a little hard to fit an entire news story in, but people are giving less and less attention to the news these days anyway.
