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

Question: what do alcohol, cocaine, heroine , marijuana, methamphetamines and ketamine have in common with the Internet? The answer, apparently, is that they all can both change your brain chemistry in the same way, once you’ve become addicted to them.

Tracheae (aka windpipes) don’t grow on trees. In fact, they don’t grow anywhere, which is problematic when it comes to tracheal cancer, but recently surgeons in Switzerland managed to replace a cancerous windpipe with a plastic one made in a laboratory and covered in the recipient’s stem cells .

Scientists preserve brains or body parts for various reasons. Sometimes the person had an illness that bears further study with more advanced tools than an age supplies; other times the brain in question powered an extraordinary intellect. The brains we’ll be talking about belong more to the former, and scientists have found that studying canned gray matter can provide a history of human mental health.

With science reaching the lofty heights it has , creating more mosquitoes was the only thing left to do. That’s what researchers at John Hopkins Malaria Research Institute did: genetically engineered the Anopheles mosquito’s own immune system to block the transmission of the malaria-causing parasite into humans.

Believe it or not, needles are your friends. They helpfully allow you to stab yourself in order to prevent you from getting sick or dying for one reason or another. But friends or not, it hurts like the dickens, and a new patch made of silk microneedles may be able to deliver all the drugs with none of the pain.

A granny in England recently had a writing pen removed from her stomach after being there for over 25 years and doctors were amazed to find it still writes . You know, because that’s the first thing doctors do after pulling something out of somebody: see if it still works . *considers jamming lipstick up my ass for the lulz* Apparently the woman was using the pen to push down her tongue while checking out tonsils back in 1986. She stumbled while stretching to look in the mirror, and managed to swallow the pen in the process. The pen didn’t cause any discomfort, so eventually she simply forgot about it. Whoa whoa whoa — I don’t know about you, but if I swallowed a pen I wouldn’t be forgetting about it, I would be FREAKING THE F*** OUT. *dialing 911* Holy shit man, I reaaaally don’t wanna pass this thing — get me to a doctor, STAT! Pen removed from woman’s stomach still works after 25 years [dvice] Thanks to c-nasty, who once swallowed a chopstick and shit what looked like a shish-kabob. Okay you’re disgusting.
