In space, no one can hear you scream. This is a problem, since if you're screaming in space, there's a good chance you desperately need surgery for one reason or another. To address this, the ESA has come up with the fancy little hat that uses augmented reality to turn just about anyone into a skilled surgeon, even in spaaace.
When an 83 year-old Belgian woman had a seriously infected jaw, a 3D printer came to the rescue. When aren't 3D printers coming to the rescue these days?
Science has finally gone and done something useful for a change by inventing a mouthwash that they say can completely eliminate the bacteria responsible for tooth decay. Refined sugar, you and me have a brand new (and sparkly white) future to look forward to.
Faced with a society that's getting chubbier by the Twinkie, the Army has been looking for a way to get itself more recruits that doesn't involve (additional) lowering of its physical fitness requirements. So what has the Army come up with? Why, transplanting extra fat cells into the body to make people insta-skinny, of course. I mean, duh.
Optogenetics is a method of using light to control cells in the brain. It can be used to alter behavior, model diseases, and maybe even one day, deliver drugs right where you need them. And now, it's wireless! With lasers!
High up on the list of things that it seems like a very bad idea to swallow are hydrogen-powered rockets. But researchers looking for new ways to deliver drugs inside the stomach have developed little microrockets powered by microbubbles and steered by micromagnets that are apparently perfectly safe to ingest. Yum?
There's really no easy way to talk about a camera that you swallow and swims through your colon, so we'll just forge ahead. All mental discomfort aside, this next generation capsule camera is pretty cool — it has a tiny motor that is guided wirelessly by an MRI that allows doctors to steer it for maximum precision.
It's a good day to be a mouse with a premature aging disease, as researchers at the University of Pittsburgh Medical Center have discovered that injecting old mice with a bunch of young stem cells can double or triple their lifespans.
Believe it or not, needles are your friends. They helpfully allow you to stab yourself in order to prevent you from getting sick or dying for one reason or another. But friends or not, it hurts like the dickens, and a new patch made of silk microneedles may be able to deliver all the drugs with none of the pain.
The whole point of an exoskeleton is to make you feel stronger, faster, more powerful, and just generally way more awesome. The point is not to make you feel like an old person, like this one does.
