Treating cancer is difficult because there's no easy way for a treatment to differentiate between healthy cells and cancerous cells. Somehow, you need to know if a cell is cancerous, then treat it, or else don't touch it. It would be great if we could program cells themselves with that logic, and as it turns out, we can.
No, this isn't some viral marketing for True Blood...I think. Some researchers at Stanford have just published a study that claims that when blood from a young mouse was injected into an old mouse that old mouse received a "rejuvenation effect."
There's still an awful lot that's not understood about how complex biological systems (like our bodies) really work. Part of the problem is that we can't just go look, since the only way to really see inside a brain (for example) is to cut it open, which by definition destroys its structure. Japanese scientists have a better idea: just turn everything transparent.
It's like something out of science fiction or a horror movie or both: in order to facilitate transplants, we can now keep human hearts alive and beating and toasty warm inside a special electromechanical box full of fresh blood.
What's Novak Djokovic's secret to being one of the best tennis players in the world? Natural talent and countless hours of practice, I'm guessing. Or maybe this egg-shaped pressurized oxygen chamber. One of the two!
Stories of bionic limbs doing this or that for people never ceases to brighten up my day. Here's another: Britain's Chloe Holmes, 15, lost her fingers at a very young age. Now, she's get a brand new pair, and they're just about as good as anyone else's.
Researchers at Vanderbilt University in Tennessee have paired both a powered knee and ankle, working in tandem, to create a bionic limb that is just about as good as the original. It's the first prosthetic limb to use said motorized joints in conjunction, and the results are impressive to see in motion.
14-year-old Matthew James wrote to the head of Mercedes' F1 team asking them for $57,000 for a bionic hand. It was kind of a joke when he sent it off, but the hand they made him in response certainly isn't; it's the most advanced prosthetic hand in the world.
Getting HIV test results usually takes days for the clinic to drop the news on you, but a new credit-card-sized chip called the "mChip" only takes 15 minutes to diagnose a sample of blood. It's also only $1 and is reportedly has a 100 percent detection rate. Sounds superb, if you think you might have HIV or syphilis, right?
You generally have to get a flu shot every year, as the vaccine needs to be updates to take on the specific mutations of the virus that are floating around that season. But researchers are working on a new flu vaccine that would last for years.
