![]() Seattle: Facebook has gone on to enhance its face detection feature, launched in July 2010, and has come up with a new feature called "tag suggestions". The new feature makes use of face recognition technology (FRT) to suggest which friend is probably featured in which photo. How it works is, say you have uploaded a huge number of photographs, Facebook will group together the faces that look similar, based on the premise that they are photos of the same person. Facebook also goes and looks into the past photo tags and suggests who in the picture. Facebook believes the new feature will simplify the process of photo sharing. Also for users who want to maintain their privacy and not have their name suggested, they can use the privacy settings of the site and turn off the feature. The earlier face detection feature allowed users to only tag the photos and not suggest the faces. This feature is included with the recent profile update of facebook.

![]() (AP/CBS) An orbiting NASA telescope is finding whole new worlds of possibilities in the search for alien life, including more than 50 potential planets that appear to be in the habitable zone. In just a year of peering out at a small slice of the galaxy, the Kepler telescope has spotted 1,235 possible planets outside our solar system. Amazingly, 54 of them are seemingly in the zone that could be hospitable to life - that is, not too hot or too cold, Kepler chief scientist William Borucki said. Until now, only two planets outside our solar system were even thought to be in the "Goldilocks zone." And both those discoveries are highly disputed. Fifty-four possibilities is "an enormous amount, an inconceivable amount," Borucki said. "It's amazing to see this huge number because up to now, we've had zero." The more than 1,200 newfound bodies are not confirmed as planets yet, but Borucki estimates 80 percent of them will eventually be verified. At least one other astronomer believes Kepler could be 90 percent accurate. (NPR.org) As NASA somberly marks the 25th anniversary of the space shuttle Challenger accident, the agency is looking ahead to the retirement of its aging space shuttle fleet later this year. The next astronauts to travel to space may go instead by private spacecraft designed and owned by commercial companies such as Virgin Galactic.
But a deadly accident like Challenger could have serious ramifications for the fledgling commercial space industry as it tries to take over the job of ferrying astronauts up to low Earth orbit and the International Space Station. Any accident would probably result in a long investigation and spaceflights being grounded — after Challenger and Columbia, it was years before the shuttles flew again. What would that do to a private company? "A lot depends on how the private company reacts, and a lot of it depends on the root cause of the failure," says Ken Bowersox, a former NASA astronaut who now works on safety issues for SpaceX, one of the private companies vying to someday take NASA astronauts and other paying customers to orbit. ![]() (CBS) This Edison guy - it turns out that he knew a few things. As if we needed any proof, the Wizard of Menlo Park had a keen insight into how technology would go on to shape our lives. In an interview with the Miami Metropolis in 1911, Thomas Alva Edison sketched out a future in which:
![]() Microcapsules in a Self-Healing Polymer (Technologyreview.com) A polymer that mends itself could lead to medical implants or engine parts that fix themselves. A new polymer material that can repeatedly heal itself at room temperature when exposed to ultraviolet light presents the tantalizing possibility of products that can repair themselves when damaged. Possibilities include self-healing medical implants, cars, or even airplane parts. The polymer, created by researchers at Carnegie Mellon University and Kyushu University, heals when a crack in the material is pressed together and exposed to UV light. The same treatment can cause separate chunks of the material to fuse together to form one solid piece. The researchers were able to cut the same block into pieces and put them back together at least five times. With further refinement, the material could mend itself many more times, says CMU chemistry professor Krzysztof Matyjaszewski, who led the research team. |
