After a heart attack, your heart can become weak to the point that it's no longer able to effectively supply the rest of your body with blood. This means bad times, especially since patients with severe heart failure have to rely on mechanical devices or transplants, but stem cells derived from a patient's own skin could potentially provide a cure.
Rodents are typically the immediate beneficiaries of new medical tech, which is only fair as they deal with the other end of things, too. Usually just trying random stuff doesn't yield much in the way of benefits, but as it turns out, stuffing rats full of carbon 60 molecules increases their lifespan. By a lot.
Getting a good amount of exercise is hard work. I mean, that's kind of the point, I guess. But what counts a "good amount?" Twenty minutes a day? Or maybe an hour at the gym, three times as week? Science has spoken, and it turns out that a "good amount" is a lot less than you think. Excuse me, I'll be on the couch.
Did you know that trained dogs can identify breath samples from patients with lung cancer with 98 percent accuracy? We can't yet match the nozzalicious expertise of our canine companions, but we're getting closer, and a company has been able to create a breathalyzer that can chemically sniff out lung cancer almost as well.
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?
