medical tech stories

 
Drugs are just molecules that are small enough to interact with the cells in your body. We've discovered a lot of them: 67 million unique substances, according to the American Chemical Society. But this is only about one tenth of one percent of the potential drugs out there, so we've definitely got some work to do.
 
Your body, in many ways, is a computer. It's not wired with silicon, but relies on chemical pathways to transmit and receive information and instructions. Conventional electronics may not play well with biology, but the invention of the first artificial chemical circuit could be the key to interacting directly with our cells.
 
It's often hard to tell just where in the brain depression comes from. A company called Brainsway has developed an electromagnetic "shotgun" that can stimulate a bunch of different areas of the brain all at once, and after promising trials, it's applying for FDA approval to use it clinically.
 
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.
