Today’s most advanced prosthetic limbs can restore one’s ability to manipulate objects, but there’s still a wide berth between that and the ability to feel. Inventors have found ways to simulate this, but may not have to for long: a new “scaffold” could bridge the gap between severed nerves and machine limbs.

Do you make a point of going to bed early so that you can get eight solid hours of uninterrupted sleep ? Well, YOU’RE DOING IT WRONG. Human sleep cycles were a lot different just a few hundred years ago, with waking up for a few hours in the middle of the night being the norm. We can likely blame technology for the change, and it may not be for the best.

Getting 8 hours of restful sleep may be unnatural
This reminds me of that old riddle: What took ten years to develop and could potentially save around 350,000 lives a year from an often asymptomatic infectious disease that generally attacks (and causes cirrhosis of) the liver?

Let me just say that one more time: laser-powered carbon nanotube exploding drug grenades. We have them.

Getting a good amount of exercise is hard work . I mean, that’s kind of the point, I guess. But what counts a “good amount?” Twenty minutes a day? Or maybe an hour at the gym, three times as week? Science has spoken, and it turns out that a “good amount” is a lot less than you think. Excuse me, I’ll be on the couch.

Did you know that trained dogs can identify breath samples from patients with lung cancer with 98 percent accuracy? We can’t yet match the nozzalicious expertise of our canine companions, but we’re getting closer, and a company has been able to create a breathalyzer that can chemically sniff out lung cancer almost as well.

Breathalyzers can now test for lung cancer
Lil’ Wayne once said, “Off the rat, he won’t rat no more.” Elegant as Weezy’s lyrics were, he might be using “rat” a little incorrectly, since it turns out rats are predisposed toward helping each other ( among other things ). Rats, long known to be social creatures, will help each other escape from “prison,” so to speak. They display actual empathy.

Optogenetics is a method of using light to control cells in the brain. It can be used to alter behavior, model diseases, and maybe even one day, deliver drugs right where you need them. And now, it’s wireless! With lasers !

The female g-spot: much like a fountain of youth or an all-you-can-eat buffet where the other patrons aren’t so fat that you’re too disgusted to eat, men have spent centuries trying to find one. And now penis doctor urologist Amichai Kilchevsky adds his two cents to the growing amount of skepticism about a mythical come-button. Based on a review of 96 published studies, an Israeli and American research team came to one conclusion. “Without a doubt, a discreet anatomic entity called the G-spot does not exist,” said Dr. Amichai Kilchevsky, a urology resident at Yale-New Haven Hospital in Connecticut, and lead author of the review, published Jan. 12 in the Journal of Sexual Medicine. Kilchevsky conceded the work is not “1,000 percent conclusive,” allowing that other scientists could one day find something his team missed. But they would need new technology to do it, he said. AHAHHAHAHAHHAHAHAHA!! Sorry Amichai, but anybody calling themselves a doctor who uses phrases like “1,000 percent conclusive” can’t be trusted. Sucks too because I was really hoping there wasn’t a g-spot. Oh well, looks like it’s back to studying the vagina map my friend drew for me in middle school! Now if my calculations are correct, then this X should mark the spot. “Your maps upside down.” So…. “So that would be her b-hole.” B -hole, G -spot — I think I’m getting warmer! G-Spot Does Not Exist, ‘Without A Doubt,’ Say Researchers [huffingtonpost] Thanks to PYY, who doesn’t care if there’s a g-spot or not just so long as she can… you know — O_O
