I got tagged for this and thought it would be fun to do~

1. if you could chose any part of your body to be bionic, what would you choose and why? I think if I had to choose that I would have bionic arms that would be useful later in life. I could keep sewing, gaming like crazy and generally look like a bad arse goth granny~

2. someone gives you $10,000 and you have to spend it in 4 hours. what do you do with the money? depositing it in your bank account or otherwise finding a way to save it does not count! I’d use it as a down payment to get my mom a new house. We would just have to find one fast lol

3. you end up stuck inside of a hotel room while on vacation with your current favorite fictional character due to inclement weather. what do y’all do to pass the time? Uhhh..Honestly, probably what we end up doing in the hotel rooms for cons even if they were there. Drink, play cards against humanity and watch HDTV. I’d probably end up being nervous or shy for a bit x.x

4. would you rather receive $10,000,000 or be able to rewind your life back to the time of your choosing and still keep your current knowledge? The money. My life had its ups and downs but I think things turned out as well as can be as they are and would rather not relive anything.

5. when you have nightmares, what are they about? My most common nightmare tends to be about ghosts chasing me. The worst ones are when I end up cursed and have a ghost similar to the grudge lady chasing me. I don’t know why but she scares me so much T.T. I also have a lot of the end of world/civilization scenarios where it’s pretty much every person for themselves. Everyone I know is dead and everyone I see is a possible enemy that makes it very isolating.I probably just play too much Shin Megaten x.x

6. what was the last thing to make you genuinely, truly happy? could be something profound or super simple, but basically when was the last time you truly smiled? My cat will hop up on me while I’m lying down and start pawing at me to pet her. Sometimes she’ll paw at my face when I’m sleeping to get me to do so lol. It’s adorable.

7. top or bottom? Top I guess? o.o

8. what’s your favorite film pre-1980s It would definitely have to be the Rocky Horror picture show. Love it so much and watched it enough to know almost all the songs <3

9. what is your perfect pizza? I’m not really too picky about my pizza toppings. Just as long as there’s no olives..Ugh I hate the taste of them.

10. if you could personally witness something in all of history, what would it be? It’d probably be either to go back in time and see one of the Venetian Masquerade balls or to see the classical artists paint or sculpt back in Florence during the Renaissance period. I think it’d just be inspiring to see.

11. describe the last person you sent a text message to in five words very sweet friend from Dallas

New questions

1. What’s your favorite video game and why? If you don’t have a favorite game, it could be a movie instead.

2. Where would you travel to if time and money were not limitations?

3. What’s your favorite food of all time?

4. If you had the chance to be on a reality TV show, would you do it?

5. If you could relive a certain moment in your life, what would that be?

6. Do you have any pets?

7. What fictional character would you say that you are like the most personality wise?

8. What inspires you?

9. What was your favorite class to take in school and why?

10. Would you ever write a book? If you did, what would it be about?

11. Describe one of the weirdest dreams you’ve ever had.

Adrianne Haslet-Davis dances again for the first time since the Boston terrorist attack last year. 

When the bombs went off at the Boston Marathon finish line, Adrianne Haslet-Davis lost the lower half of her left leg in the explosion. She’s a ballroom dance teacher, and she assumed she would never dance again. With most prosthetics, she wouldn’t.

But Hugh Herr, of the MIT Media Lab, wanted to find a way to help her. He created a bionic limb specifically for dancers, studying the way they move and adapting the limb to fit their motion. (He explains how he did it here.)

At TED2014, Adrianne danced for the first time since the attack, wearing the bionic limb that Hugh created for her.  

Hugh says, “It was 3.5 seconds between the bomb blasts in the Boston terrorist attack. In 3.5 seconds, the criminals and cowards took Adrianne off the dance floor. In 200 days, we put her back. We will not be intimidated, brought down, diminished, conquered or stopped by acts of violence.”

Amen to that, Hugh.

DIY bionics - making kids smile again.

See the joy in Liam’s eyes as he is grasping a ball with his right hand for the first time. By the time this cute fellow grows up, he will have a bionic hand that will be connected to his neural-system and be indistinguishable from his biological body; but for now all Liam cares about is being able to play ball.

Watch: Ian Burkhart, a 23-year-old quadriplegic man, just moved his arm — with his mind

Burkhart had been unable to move his arms or legs since a diving accident four years ago damaged his spinal cord and left him paralyzed. But thanks to a new device that reroutes his brain signals, Burkhart was recently able to lift his hand using his thoughts.

The technology, called Neurobridge, takes electric signals from the brain and sends them directly to the muscles, bypassing the damaged spinal cord.

The £90,000 ‘robolegs’ that got me out of my wheelchair: How one woman stood on her own feet nine years after she was paralysed

It is an extraordinary sight. From the waist up, 27-year-old Sophie Morgan is every inch the pretty blonde girl-next-door. But from the waist down, with her legs encased in £90,000 of motorised carbon-fibre, she is RoboCop.

Sophie’s thumb manipulates a joystick built into the armrests of her suit, causing the legs to hiss and whirr into life, before she takes three slow but sure steps. Her face breaks into a broad grin.

Five minutes earlier, Sophie was in her wheelchair. She was left paralysed from the chest down in a car crash nine years ago that shattered her spine. Over the years, Sophie, an aspiring television presenter who appeared in Channel 4’s Paralympics coverage, had come to accept that she would never walk again.

Meet Claudia Mitchell, the first woman with a bionic arm.

 In 2006 she was outfitted with the arm to replace the arm she lost in a motorcycle accident. Her prosthesis, a prototype developed by the Rehabilitation Institute of Chicago is one of the most advanced prosthetic arms developed to date.

Mitchell, who lives in Ellicott City, was the fourth person- and first woman- to receive a “bionic” arm, which allows her to control parts of the device by her thoughts alone. The device works by detecting the movements of a chest muscle that has been rewired to the stumps of nerves that once went to her now-missing limb. 

She hopes to upgrade to a prosthesis, still under development, that will allow her also to “feel” with an artificial hand. 

A while after the initial surgery, surgeons took the first step by rewiring the skin above her left breast so that when the area is stimulated by impulses from the bionic arm, the skin sends a message to the region of her brain that feels “hand.” 

Future arms will be able to perform even more precise movements, but even the first-generation device “has changed my life dramatically,” she said. “I use it to help with cooking, for holding a laundry basket, for folding clothes — all kinds of daily tasks.” 

Technology like this gives hope for the future because it is a great example how science can actually improve the quality of people’s life!

TED: Hugh Herr - The new bionics that let us run, climb and dance

Hugh Herr is building the next generation of bionic limbs, robotic prosthetics inspired by nature’s own designs. Herr lost both legs in a climbing accident 30 years ago; now, as the head of the MIT Media Lab’s Biomechatronics group, he shows his incredible technology in a talk that’s both technical and deeply personal — with the help of ballroom dancer Adrianne Haslet-Davis, who lost her left leg in the 2013 Boston Marathon bombing, and performs again for the first time on the TED stage.

Amputee Feels in Real-Time with Bionic Hand

Nine years after an accident caused the loss of his left hand, Dennis Aabo Sørensen from Denmark became the first amputee in the world to feel – in real-time – with a sensory-enhanced prosthetic hand that was surgically wired to nerves in his upper arm. Silvestro Micera and his team at EPFL Center for Neuroprosthetics and SSSA (Italy) developed the revolutionary sensory feedback that allowed Sørensen to feel again while handling objects. A prototype of this bionic technology was tested in February 2013 during a clinical trial in Rome under the supervision of Paolo Maria Rossini at Gemelli Hospital (Italy). The study is published in the February 5, 2014 edition of Science Translational Medicine, and represents a collaboration called Lifehand 2 between several European universities and hospitals.

“The sensory feedback was incredible,” reports the 36 year-old amputee from Denmark. “I could feel things that I hadn’t been able to feel in over nine years.” In a laboratory setting wearing a blindfold and earplugs, Sørensen was able to detect how strongly he was grasping, as well as the shape and consistency of different objects he picked up with his prosthetic. “When I held an object, I could feel if it was soft or hard, round or square.”

From Electrical Signal to Nerve Impulse
Micera and his team enhanced the artificial hand with sensors that detect information about touch. This was done by measuring the tension in artificial tendons that control finger movement and turning this measurement into an electrical current. But this electrical signal is too coarse to be understood by the nervous system. Using computer algorithms, the scientists transformed the electrical signal into an impulse that sensory nerves can interpret. The sense of touch was achieved by sending the digitally refined signal through wires into four electrodes that were surgically implanted into what remains of Sørensen’s upper arm nerves.

“This is the first time in neuroprosthetics that sensory feedback has been restored and used by an amputee in real-time to control an artificial limb,” says Micera.

“We were worried about reduced sensitivity in Dennis’ nerves since they hadn’t been used in over nine years,” says Stanisa Raspopovic, first author and scientist at EPFL and SSSA. These concerns faded away as the scientists successfully reactivated Sørensen’s sense of touch.

Connecting Electrodes to Nerves

On January 26, 2013, Sørensen underwent surgery in Rome at Gemelli Hospital. A specialized group of surgeons and neurologists, led by Paolo Maria Rossini, implanted so-called transneural electrodes into the ulnar and median nerves of Sørensen’s left arm. After 19 days of preliminary tests, Micera and his team connected their prosthetic to the electrodes – and to Sørensen – every day for an entire week.

The ultra-thin, ultra-precise electrodes, developed by Thomas Stieglitz’s research group at Freiburg University (Germany), made it possible to relay extremely weak electrical signals directly into the nervous system. A tremendous amount of preliminary research was done to ensure that the electrodes would continue to work even after the formation of post-surgery scar tissue. It is also the first time that such electrodes have been transversally implanted into the peripheral nervous system of an amputee.

The First Sensory-Enhanced Artificial Limb
The clinical study provides the first step towards a bionic hand, although a sensory-enhanced prosthetic is years away from being commercially available and the bionic hand of science fiction movies is even further away.

The next step involves miniaturizing the sensory feedback electronics for a portable prosthetic. In addition, the scientists will fine-tune the sensory technology for better touch resolution and increased awareness about the angular movement of fingers.

The electrodes were removed from Sørensen’s arm after one month due to safety restrictions imposed on clinical trials, although the scientists are optimistic that they could remain implanted and functional without damage to the nervous system for many years.

Psychological Strength an Asset
Sørensen’s psychological strength was an asset for the clinical study. He says, “I was more than happy to volunteer for the clinical trial, not only for myself, but to help other amputees as well.” Now he faces the challenge of having experienced touch again for only a short period of time. 

Sørensen lost his left hand while handling fireworks during a family holiday. He was rushed to the hospital where his hand was immediately amputated. Since then, he has been wearing a commercial prosthetic that detects muscle movement in his stump, allowing him to open and close his hand, and hold onto objects.

“It works like a brake on a motorbike,” explains Sørensen about the conventional prosthetic he usually wears. “When you squeeze the brake, the hand closes. When you relax, the hand opens.” Without sensory information being fed back into the nervous system, though, Sørensen cannot feel what he’s trying to grasp and must constantly watch his prosthetic to avoid crushing the object.

Just after the amputation, Sørensen recounts what the doctor told him. “There are two ways you can view this. You can sit in the corner and feel sorry for yourself. Or, you can get up and feel grateful for what you have. I believe you’ll adopt the second view.”

“He was right,” says Sørensen.
