Hasta La Gadget!

Here’s one for the medical journals: researchers at London’s Imperial College have created a high-tech scalpel that can differentiate between cancerous and non-cancerous tissue as it cuts. The team calls it the iKnife (intelligent knife), and by analyzing vapors created during electrosurgical dissection in real time, it takes only seconds to distinguish healthy flesh from affected tissue. The device’s inventor, Zoltan Takats, says it has the potential to speed up cancer surgery considerably, as current analysis techniques performed mid-operation can take up to 30 minutes. It could also prevent follow-up surgeries prompted by undetected cancer cells. Unfortunately, the iKnife still has to go through more tests before we can add it to our arsenal of weapons against cancer — until then, we’ll just have to make do with run-of-the-mill electrosurgical knives.

There’s a lot of research to help the spinal cord or stroke-injured become more self-sufficient, but it often takes some exotic paraphernalia. To buck that trend, scientists from Imperial College London showed that subjects could perform relatively hard tasks like writing messages and playing Pong using eye movement — with a mere $35-worth of parts. They even showed how well the system worked, with subjects scoring within 20 percent of an able-bodied person after a scant 10 minutes of practice. The tracker works with two video console cameras and a pair of eyeglasses that, after calibration, can precisely track the pupils — allowing them to control a cursor or move a paddle. The researchers also figured out how to “click” the eye-mouse by winking, and can even use more precise adjustments to calculate gaze depth — meaning subjects will be able to perform more complex tasks in the future, like guide a motorized wheelchair. While by no means the first eye-tracking system we’ve seen, it’s by far the most economical. Check the video after the break to see how it works.
