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.
Here's some good news or bad news depending on how you look at it. The good news is that birth control pills could soon be replaced by a simple gel that works even if you rub it on your shoulders. The bad? The daily moisturizing routine could get a lot more stressful.
For the current crop of state-of-the-art prosthetic arms, you have to control the fingers and finer movements with your feet. It takes a lot of getting used to and is completely unlike using a normal arm. But a new model...
One of the big dangers of open wounds is infection — when bacteria get in and generally make a bad situation a lot worse. Now a group of Chinese scientists have figured out a way to make bandages with built-in bacteria barriers.
For the first time ever, rats implanted with lab-grown lungs were able to breathe and oxygenate their blood. It's a huge step towards being able to grow organs for people who need replacements, ending the need for live-patient transplants.
