A hand-held scanner that can detect cancer at a patient’s bedside using just a speck of tissue has been created by scientists from Harvard University and Massachusetts Institute of Technology.

Nokia is committed to get back the No.1 position in smartphones and is nervous about getting too cozy with Google. Instead, it plans to use the robust software platform of Symbian and Linux MeeGo, head of its mobile solutions unit said. (Video on the Morph)
Last year, Pentagon mad science arm Darpa was working on one of its wildest projects yet: a microchip-sized nuclear reactor. The program is now officially done, the agency says. But these sorts of far-out projects have a habit of being reemerging under new managers and new names.
This device lets surgeons attach small anchors to tissue inside a beating heart by compensating for the heart’s movement.
Fixing the heart is hard. Certain procedures have to be performed on a stationary organ, so the heart is stopped and the patient put on a cardiopulmonary bypass machine. But stopping the heart increases the risk of brain damage. Now researchers at Harvard University and Children’s Hospital Boston are testing a robotic system that could help surgeons perform a common valve repair while the heart beats on. The system uses 3-D ultrasound images to predict and compensate for the motion of the heart so that the surgeon can work on a patient’s mitral valve as it moves.
