One of the biggest drawbacks of today's prosthetic limbs is that they don't provide the sensation of touching something. Scientists have made progress restoring the sense of touch for amputees by rerouting hand nerves to the chest after amputation. Now, when physical pressure, heat, or cold is applied to those nerves, the patients reported feeling the sensations in their nonexistent hands. From AFP:
In some of the testing, the patients could even specify which area on the hand they could feel; one, a woman identified as STH, at one point pinpointed a strong feeling of the skin stretching and the joint position of her ring finger being extended...
The scientists suggest their success in reviving such specific sensation identified with missing limbs could lead to establishing nervous system feedback in prosthetic devices like artificial hands, arms, feet and legs.
"Our results illustrate a method for creating a portal to the sensory pathways of a lost limb," they said in the online edition of the Proceedings of the National Academy of Sciences.
"This work offers the possibility that an amputee may one day be able to feel with an artificial limb as though it were his own."
David Robinson used the data from the 28,657 people who self-selected to take the Stack Overflow survey to investigate the relationship between programmer pay and the conventions of using either tabs or spaces to mark indents, and found a persistent, significant correlation between using spaces and bringing home higher pay.
It’s the end of an era, sort of: Fraunhofer IIS, the developers of the MP3 audio compression format, announced that they are ceasing their licensing program. In a blog post, spokesman Matthias Rose says that it’s had a good 20-year run and is obsolete. But it’s also true that the decoding patents expired last year, […]
Freddy deBoer writes that he’s been telling the same joke for years about Silicon Valley’s only product, which might be universalized as “At last, a way to verb with nouns on the internet!” But the social-media techopoly is stable, now, and so the venture capitalists have moved on to the three terrible trends that will […]

Even though credit cards now feature an EMV chip for securing transactions, they still have to include the magnetic strip for compatibility with older point of sale systems. Because of this, there’s no way for the chip’s new security capabilities to protect against card skimmers in the wild.How do you protect yourself from legacy-technology-induced fraud? […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
