Last week surgeons at the University of Maryland Medical Center performed the most extensive face transplant ever completed. 37-year-old Richard Lee Norris received donor skin from his scalp to his neck as well as a new nose, tongue, jaw bones and teeth.
Studies recently concluded on astronauts who have flown long-term missions that could point to serious problems with prolonged exposure to microgravity. This adds to the list of physical concerns NASA is addressing when considering long-term space travel.
Origami paper folding has long been a traditional art form, but now researchers at the University of Texas at Austin have been inspired to use paper folding as a way to test for diseases. The idea expands on existing paper sensor tests, but the folding allows it to detect more complex substances and diseases.
Weight-loss drugs generally work in one of two ways: they suppress your appetite so that you eat less, or they attempt to reduce the amount of fat that your body absorbs. Neither of these methods deal with the fat that you already have, but a new drug that targets those cells has shown some promising results in primate trials.
The first human genome cost $3 billion to sequence back in 2003. By 2009, the cost to sequence someone's genome had dropped to more like $50,000. Next year, the target is a mere $1,000, and it'll only take two hours to completely identify all six billion of the base pairs in your DNA to tell you what you're likely to die from first.
We're not even at the point where we're allowed to get all up in people's stem cells to help cure diseases, but researchers are already thinking ahead to how we can use stem cells to treat genetic diseases, which should be impossible. Or, it was impossible, until we just did it.
Part of what makes HIV such a nasty virus is that it attacks our immune system, which is what we have around to keep viruses from attacking us. We may have just figured out how to keep HIV from exploiting our immune response, meaning that our bodies could fight it off just like any other virus.
Ever since the accidental discovery of penicillin, we've had ways of being able to deal with bacterial infections. With viral infections, like when you get a cold, all we can really do is suck it up and treat the symptoms, but a new type of drug may be able to tackle any virus, even the ones we haven't met yet.
Being sick sucks. And while we can't always cure what ails us, researchers at Oregon Health & Science University have figured out where that general feeling of lousiness we get when we're stick actually comes from, and they think they can make it go away.
This only works on mice so far, but researchers have discovered that altering a specific protein in the brain can pinpoint and delete traumatic memories on a molecular level.
