Super-Earths Discovered Orbiting Nearby, Sun-Like Star 242

likuidkewl writes "Two super-earths, 5 and 7.5 times the size of our home, were found to be orbiting 61 Virginis a mere 28 light years away. 'These detections indicate that low-mass planets are quite common around nearby stars. The discovery of potentially habitable nearby worlds may be just a few years away,' said Steven Vogt, a professor of astronomy and astrophysics at UCSC. Among hundreds of our nearest stellar neighbors, 61 Vir stands out as being the most nearly similar to the Sun in terms of age, mass, and other essential properties."

Submission + - Girl's heart regenerates due to artificial assist (www.cbc.ca) 1

Socguy writes: "A 15-year-old girl has become the first Canadian to have an artificial heart removed after her own heart healed itself.
Doctors at the Stollery Children's hospital implanted the Berlin Heart, a portable mechanical device that keeps blood pumping in an ailing heart, so she could survive until a transplant became available.
But over the next few months, Melissa's overall condition improved dramatically, and her heart muscle regained much of its strength. After 146 days on the Berlin Heart, Melissa underwent surgery to have the device removed.
