An Italian who lost his left forearm in a car crash was successfully linked to a robotic hand, allowing him to feel sensations in the artificial limb and control it with his thoughts, scientists said Wednesday.
During a one-month experiment conducted last year, 26-year-old Pierpaolo Petruzziello felt like his lost arm had grown back again, although he was only controlling a robotic hand that was not even attached to his body.
…
Petruzziello, an Italian who lives in Brazil, said the feedback he got from the hand was amazingly accurate.
“It felt almost the same as a real hand. They stimulated me a lot, even with needles … you can’t imagine what they did to me,” he joked with reporters.
While the “LifeHand” experiment lasted only a month, this was the longest time electrodes had remained connected to a human nervous system in such an experiment, said Silvestro Micera, one of the engineers on the team. Similar, shorter-term experiments in 2004-2005 hooked up amputees to a less-advanced robotic arm with a pliers-shaped end, and patients were only able to make basic movements, he said.
Experts not involved in the study told The Associated Press the experiment was an important step forward in creating a viable interface between the nervous system and prosthetic limbs, but the challenge now is ensuring that such a system can remain in the patient for years and not just a month.
In this provocatively titled lecture, from the very aptly named Festival of Dangerous Ideas , Julian Savulescu, Uehiro Professor of Practical Ethics at the University of Oxford and Head of the Melbourne–Oxford Stem Cell Collaboration:
…examines the nature of human beings as products of evolution, in particular their limited altruism, limited co-operative instincts and limited ability to take account of the future consequences of actions. He argues that humans’ biology and psychology are unfit for the kind of society we live in and we must either alter our political institutions, severely restrain our technology or change our nature. Or face annihilation by our own design.
Which is a nice way of saying he makes a strong case for meddling in the genes of our children, and more importantly, can now identify just which ones to tweak.
This is nugenics kids, and it’s shit scary.
(OK, it would be slightly less creepy if he wasn’t wearing his suit jacket like a cape)
Watch on and be afraid; sooner or later a Government somewhere is going to try this!
The QnA starts mid-way through the second video and is particularly good, in that most of the questions you will have are actually asked by the audience.
thanks to my buddy The Dingo Strategy for the tip-off!
In this video from Activate 09Nick Bostrom gives a short overview of world history, coming threats to the planet and the likelihood of posthumanity arising.
Nick is a philosopher we’ve perhaps neglected a tad here so far. Firstly, he’s Swedish, so you may struggle to parse his accent. Just watch the slides then, you’ll get a feel for what he’s saying.
Secondly, he’s the director of the Oxford Institute for the History of Humanity. As opposed to pure technologists like Ray Kurzweil he does more than just quote Moore’s Law, and his writings range around a variety of subjects.
You could also buy the book he’s contributed to, Human Enhancement, and send us in a review. It looks fascinating, but I don’t think I’ll have time to read it in the near future.
