In a perfect world, your smartphone would automatically tag whatever it sees through the camera's field of view. This could be helpful when using Google Glass, facial recognition systems, robotic cars and more.
Big powerful computers can do it already with something called deep learning. It requires layers of neural networks that mimic how the human brain processes information. A Purdue University researcher is working on it for smartphones and mobile devices.
When diagnosing and repairing the heart's electrical system, doctors often have to use lots of radiation to pinpoint the problem. It's not uncommon for the patient to experience 50 minutes or more of radiation thanks to X-rays, CAT scans and nuclear stress tests.
Right now traveling to Mars would be a full-time commitment. Astronauts would be cooped up in a rocket for seven months and if they were able to take enough fuel to get back to earth, they would have to wait another two years before the planets would be close enough again. During this time their bone densities would greatly decrease and crumble once back on earth.
GE Aviation has so much faith in 3D printing that it will soon relocate its Sharonville facility to a much larger space. GE bought what used to be called Morris Technologies in 2012. Morris was the first to introduce 3D metallic based technology to North America.
The technology works by taking a very fine grain metal powder and thinly layering it using a laser. This is different than taking solid material and subtracting it to make a part, like is done in machining.
