3D-printed implants just got one of their biggest real-world tests to date. Peking University Third Hospital has successfully implanted the first 3D-printed vertebra in a 12-year-old boy with cancer in his spinal cord. The bone substitute is made from titanium powder like many orthopedic implants,

Cochlear implants already help those with auditory damage to hear better, but what if they could also grow new nerves while they're there? Scientists at the UNSW have discovered a way to do just that, at least in hamsters. After they introduced a gene therapy solution, a modified cochlear implant

Pacemakers and other electronic implants are a pain to keep running -- patients need surgery to replace batteries, and body-powered generators aren't currently strong enough to charge these devices. They may be far more practical in the future, though, as American and Chinese researchers have deve

Most of the attention surrounding 3D printers in medicine has focused on patching up our outsides, whether it's making skin to heal wounds or restoring the use of limbs. The Wake Forest Institute for Regenerative Medicine has just detailed a technique that could go considerably deeper. By mixing n

You wouldn't immediately think of the ear's cochlea as an energy source, but MIT knows that every mammal effectively has a pair of very small power plants because of the ionized environment. School researchers are trying to harness that energy through a new sensor that exploits the whole ear canal

Controlling a cursor with your brain? Yawn. Restoring movement to paralyzed mice? Color us unimpressed. Help a wheelchair-bound man walk again using only his thoughts? Now we're talking. That's the goal of researchers at the University of Michigan who have developed BioBolt, a (comparatively) noninv

Here's an amazing story to end your week on a high note: a 25-year-old paraplegic is now walking again, thanks to a groundbreaking procedure developed by neuroscientists at the University of Louisville, UCLA and Cal Tech. The Oregon man, Rob Summers, was paralyzed below the chest in 2006, after gett
