Robot doctors join the fight against breast cancer
From Da Vinci robosurgeons to helpful nursebots , robots are becoming commonplace in hospitals the world over -- and now researchers at Duke University have developed a rudimentary tabletop robot that uses 3D ultrasound technology to detect a 'lesion' in a simulated sponge breast, pinpoint its exact location, and perform a biopsy. All the calculations are performed by the device itself, using what has been described as "a basic artificial intelligence program." The next step in the research will be an upgrade that will that the robotic arm from three-axis to six-axis capability, and a change from the old sponge-based simulated breast to one made from turkey breasts, which approximates the density of human breast tissue. According to Stephen Smith, director of the Duke University Ultrasound Transducer Group, if things stay on track, robots will be performing routine breast exams and biopsies in five to ten years.

Sensei robotic arm pulling off heart operations in the UK
Although the Sensei robot at St. Mary's Hospital in London may just be "one of four in the world," it certainly joins a packed crowd of mechanical colleagues that have been doing this whole "operation" bit for quite some time. As with most similar alternatives, this one operates (quite literally, actually) by responding to a human surgeon's input given via joystick, and the arm is then able to maneuver into more delicate and hard-to-reach locales in order to execute catheter ablation procedures. In the future, however, the Atari-lovin' doctor could be left out of the process entirely, as an automated edition could eventually be programmed to find its own way to the target without any human intervention. Med school graduates losing residency positions to metallic counterparts -- what is the world coming to?
US Army's Joint Repair Facility acts as ER for injured robots
While we're still a bit wary about letting a robotic M.D. get to work on our operating table, we certainly wouldn't trust those two-timing humanoids to sufficiently repair one of their own. Thankfully, the US Army seemingly agrees, as the volunteer-staffed Joint Repair Facility at Camp Victory provides human TLC for robots that receive injuries in the heat of battle. The facility is mostly responsible for mending and rebuilding devices that protect live soldiers from encountering improvised explosive devices, and it has reportedly increased exponentially in use and size since its inception just three years back. Notably, the gurus that work here are famous for repairing even the most obliterated of robots, and while they did admit that some bots are too damaged to repair, those are "few and far between."[Via CNET]
