Like a coin machine sorting change according to size, a new lab-on-a-chip can sift cells according to their weight and other properties. Doctors could use it to tease out biological matter from the bloodstream and detect cancer or potentially other ailments.
Absent the creation of a personalized, living avatar, computer simulations will go a long way toward helping doctors figure out what to do about your health. Sophisticated models will be able to look at your heart and predict future coronary problems, for instance. Researchers at the University of Pennsylvania are designing new simulations with virtual blood, improving the prospects for this type of tech.
Implantable medical devices will eventually dispense drugs, get rid of blood clots and perform micro-surgeries inside our bodies, but powering them could be problematic. If the point is to have minimally invasive gadgets keeping tabs on our health, cutting patients open to swap out their batteries is not an ideal situation.
On any battlefield, communication is key — troops must be able to communicate their own locations and that of their target, so everyone knows exactly where to bring the fight. MIT researchers are bringing this strategy to the war on cancer, training swarms of cancer-fighting nanoparticles to communicate to do their jobs more effectively.
When a wounded patient begins bleeding, the most commonly employed solution is decidedly low-tech: apply pressure. But a group of medical researchers have developed injectible synthetic nanoparticles that could cut bleeding time in half.
Fat sticks around in your bloodstream when you're uptight.

Stressed out? Forget that fat-laden comfort food and have something light. Researchers led by Catherine Stoney at Ohio State University have found that fat sticks around in your bloodstream when you're uptight. First the researchers injected calm people with triglycerides (any fat that comes from an animal or plant) and found that the fat left their bloodstreams at a rate of 3.2 percent per minute. But when the same subjects were asked to give a speech, solve a word problem, or quickly subtract two numbers, their bodies cleared a mere 2.8 percent of the fat each minute.
