What’s new: When somebody loses half of a leg, a prosthetic could make it simpler to get round. But most prosthetics are static, cumbersome, and laborious to maneuver. A brand new neural interface connects a bionic limb to nerve endings in the thigh, permitting the limb to be managed by the mind.
How they did it: First, sufferers endure surgical procedure to attach shin muscle, which contracts to make the ankle flex upward, to calf muscle, which counteracts this motion. The prosthetic may also be fitted at this level. In step two, floor electrodes measure nerve exercise from the mind to the calf and shin muscle groups, indicating an intention to maneuver the decrease leg. A small laptop in the bionic leg decodes these nerve indicators and strikes the leg accordingly, permitting the affected person to maneuver the limb extra naturally.
Why it issues: The new system may assist individuals with lower-leg amputations really feel as if their prosthesis is an element of them, and make strolling simpler. Read the full story.

AI corporations are lastly being pressured to cough up for training data
The generative AI growth is constructed on scale. The extra training data, the extra highly effective the mannequin. But many web sites and data set homeowners have began proscribing the means to scrape their web sites. Last week three main report labels introduced they have been suing the AI music corporations Suno and Udio over alleged copyright infringement, claiming the companies had made use of copyrighted music of their training data “at an nearly unimaginable scale.”
But this second additionally units an attention-grabbing precedent for all of generative AI improvement. Thanks to the shortage of high-quality data and the immense stress and demand to construct even greater and higher fashions, we’re in a uncommon second the place data homeowners even have some leverage. The music trade’s lawsuit sends the loudest message but: High-quality training data is just not free. Read the full story.
