There's an arms race going on between antibiotics and bacteria, and bacteria are winning. They've got evolution on their side, and there's a blajillion of them. IBM has been fighting back with bacteria-targeting "polymer ninjas," and they're poised to go beyond medicine and into consumer products.
Mosquitoes, unfortunately, have a valuable place in our ecosystem or something, so going out and nuking all of the little buggers is probably not a good option. The worst part about mosquitoes isn't mosquitoes themselves anyway: it's the malaria parasites that they carry, and genetic modification may have finally solved that problem for good.
Electronic medical implants have worked wonders for lots of people, and we're only just realizing what is potentially possible in the future. What we need, though, is a power source that doesn't involve opening people up and replacing batteries every few years, and these spinal fluid powered glucose fuel cells could make that happen.
Listen up, kids: any problem you'll ever have, ranging all from being fat to (now) being lazy, can be effortlessly be solved by taking drugs. Don't want to exercise? Just inject yourself with some of this new hormone, and you'll be on your way to the gym before you can say "recombinant human erythropoietin!"
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.
Neuroscientists at Cold Spring Harbor Laboratory have just publicly released the first batch of gigapixel images showing how the neuronal pathways in mice are all connected to each other. It's the first step towards the first ever wiring diagram of an entire vertebrate brain.
Do you eat enough fruits and vegetables? Of course you don't. And to punish you for this lack of nutritional awareness, Yale researchers have developed a laser system that can measure your intake (or lack thereof) of healthy foods right through your skin.
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.
We've got phasers. We've got tricorders. And now, thanks to MIT, we've got a hypospray that works just like the real thing, delivering programmable doses of drugs painlessly right through your skin without any needles.
