Want to Tweet at Aliens? Now You Can

Start-up begins sending text messages to the beyond

(Newser) - As of today, you can fire off a tweet-length message to a far-flung solar system, but you'll need patience—it won't get there for about 18 years, and it will take just as long to receive any extra-terrestrial response. As the Seattle Post-Intelligencer explains, a start-up called Lone...

Did a Sri Lanka Meteorite Have Fossils Inside?

Scientists fuel controversy with big claim

(Newser) - A group of scientists says a December meteorite over Sri Lanka held "fossilized biological structures"—but many of their colleagues aren't convinced.
