The first bionic hand that allows an amputee to feel what they are touching will be transplanted later this year in a pioneering operation that could introduce a new generation of artificial limbs with sensory perception.
The patient is an unnamed man in his 20s living in Rome who lost the lower part of his arm following an accident, said Silvestro Micera of the Ecole Polytechnique Federale de Lausanne in Switzerland.
The wiring of his new bionic hand will be connected to the patient’s nervous system with the hope that the man will be able to control the movements of the hand as well as receiving touch signals from the hand’s skin sensors.
Dr Micera said that the hand will be attached directly to the patient’s nervous system via electrodes clipped onto two of the arm’s main nerves, the median and the ulnar nerves.
This should allow the man to control the hand by his thoughts, as well as receiving sensory signals to his brain from the hand’s sensors. It will effectively provide a fast, bidirectional flow of information between the man’s nervous system and the prosthetic hand.
“This is real progress, real hope for amputees. It will be the first prosthetic that will provide real-time sensory feedback for grasping,” Dr Micera said.
“It is clear that the more sensory feeling an amputee has, the more likely you will get full acceptance of that limb,” he told the American Association for the Advancement of Science meeting in Boston.
“We could be on the cusp of providing new and more effective clinical solutions to amputees in the next year,” he said.
DO YOU PEOPLE EVEN REALIZE HOW AWESOME THIS IS???
TO DO THIS MEANS WE CAN FINALLY STICHT AXONS (LONG PART OF NEURON OR NERVE CELL THAT TRANSPORTS SIGNALS FROM JUNCTIONS BACK TO THE BRAIN) BACK TOGETHER
DO YOU EVEN UNDERSTAND HOW IMPOSSIBLE THAT WAS? TO ALINE THE DAMAGED AXONS BACK TOGETHER WAS IMPOSSIBLE
WITH THIS BRAKE THROUGH YOU COULD EVENTUALLY WORK UP TO GIVING THE ABILITY TO WALK AND MOVE AGAIN TO THOSE WHO CUT THEIR SPINAL CORD IN AN ACCIDENT THIS IS BEAUTIFUL
THIS. IS. AMAZING.
You can’t really blame someone who has been fed that lie all their life, no matter which sex/gender. The magazines, TV, even gyneacologists still promote the same old lies. It takes stimulation and courage to change an ages old way of thinking.
And yet, we often blame men for the same reasons… Interesting, no?
We shouldn’t blame those women, but we can, and to some extent, I guess I do a little—curiosity, for me, the best vector of discovery and a trademark expression of intelligence, is also a factor of survival and evolution.
But on the whole, I’ve never had much patience for adults with the maturity of adolescents. Note that I’m not stating this out of spite or with pride, only making the remark.
As for the professionals spreading the lies… they ought to be stripped of their privileges and demoted immediately. We are in the 21st century and this is absolutely unacceptable.
Don’t ask me why, but I was
arguingdebating with an MRA a while ago and we got on this topic, and they actually seemed surprisingly receptive to the idea that it isn’t necessary for people with vaginas to bleed when they first have sex. So I went looking for sources more reputable than Laci Green—love her videos, but most people won’t accept YouTube as a scholarly source—and all the medical websites I could stomach looking at purported that it’s totally fine and normal to bleed during your first time! I was shocked and offended.
Actually, since not all men are dirty rapists who love to hurt women in order to feel righteously patriarchal and shit, a certain number of them are genuinely afraid of hurting a female partner during first-time sex.
It’s important to teach everyone the right thing, because even if you’re not going to experience “virginity loss” first-hand, you may always help someone one day, or have children of your own who’ll need education. You’re a gay male? Well, what if you adopt a girl? You’re a happy het couple who’s just had a baby boy? Hey, that boy may have sex with a female virgin one day.
Yes, it’s fine if you bleed for your first time. It’s natural. It only means a tear was made to your insufficiently-stretched hymen. Nothing grave! However, it’s not normal, in the sense that you do not have to bleed.
Hey, you may bleed several times after the first, or you may lose a little blood years after your first time, for a bunch of reasons, but they all tie into practice, especially onto self, relaxation, and/or lubrication. It’s also possible to hurt without bleeding…
Would be a great thing to explain to more people that hymens actually grow back. And then change shape, because of your hormones. And that even your period may erode it a bit anyway. Go mutant hymens!
Good grief! I may be highly unlikely to ever do the dirty deed as it’s really not my cup of Starbucks Mocha, but even I know if you’re bleeding out of there on your non flow days and it hurts that you’re probably doing it wrong!
Also, the mention of mutant hymens has me thinking; will my vagina shoot fire or mysteriously change shape because that is its mutant power?
Suddenly procreation has become as difficult for the human man as it is for the male spotted hyena and that brings porn to a whole new level of gymnastics.
a guy at school today was wearing this damn fine red nail polish and I heard these two girls whispering angrily and looking in his direction so I listened in expecting them to be weird about it and the first thing I hear is “how the HELL did he get it so good did he get it professionally done or something you need to ask him where he found that colour jesus fucking christ are you KIDDING me”
I think this is a good example of how the world should work.
In the world of figure skating, celebrity is often judged more by personality than by competitive success.
Adelina Sotnikova may have won gold in the women’s competition at Sochi, but silver medalist Kim Yuna is still being hailed as “Yuna Queen.” Despite pulling out of the Olympics altogether, Russian superstar Evgeni Plushenko is still hogging the spotlight. And while the men’s event was dramatic enough in its own right, the skater whose every move is now being GIF’d on Tumblr isn’t one of the winners, but the guy who came in 17th.
Uzbekistani champion Misha Ge is one of those Olympic athletes who knew they probably wouldn’t be getting a medal this time around, and decided that the next-best thing was to have as much fun as humanly possible. While most skaters tend to perform a relatively classical program for the Olympics, Misha Ge danced the Mashed Potato on ice, and played air guitar while waiting for his results in the Kiss ’n’ Cry.

He also flouted a rule that even the most inexperienced viewer would be able to spot: the ban on skating to music with lyrics. This rule will actually be relaxed next season, but for now, competitors are still expected to skate to strictly instrumental music. Too bad Misha Ge’s long program involved dyeing his hair pink to match his costume, flirting with the judges, and skating to an electro-swing mashup that ended with Little Richard’s “Tutti Frutti.”
Basically, Misha Ge is not your traditional figure skating champion. Sure, he’s skated to classical music like “The Swan” in the past, but since he stopped training with star coach Frank Carroll (previous pupils: pretty much everyone who ever won a medal, it feels like) and started training with his parents again, he’s been more comfortable with music like “Gangnam Style.”
But that’s not the only reason why he’s the new No. 1 crush in figure skating fandom.
What if you could fly through the universe and see dark matter? While the technology for taking such a flight remains under development, the technology for visualizing such a flight has taken a grand leap forward with the completion of the Bolshoi Cosmological Simulation.
After 6 million CPU hours, the world’s seventh fastest supercomputer output many scientific novelties including the above flight simulation. Starting from the relatively smooth dark matter distribution of the early universe discerned from the microwave background and other large sky data sets, the Bolshoi tracked the universe’s evolution to the present epoch shown above, given the standard concordance cosmology. The bright spots in the simulation above are all knots of normally invisible dark matter, many of which contain normal galaxies. Long filaments and clusters of galaxies, all gravitationally dominated by dark matter, become evident.
Statistical comparison between the Bolshoi and current real sky maps of actual galaxies show good agreement. Although the Bolshoi simulation bolsters the existence of dark matter, many questions about our universe remain, including the composition of dark matter, the nature of dark energy, and how the first generation of stars and galaxies formed.
