However, one might argue that this analysis might not allow for sufficient differentiation between tasks. To address this concern, we expanded our evaluation to the entire MMLU benchmark. This enabled a comparable assessment of task similarity, akin to our earlier experiments.

Paralysed man can feel objects through another person's hand Keith Thomas, a man in his 40s with no sensation or movement in his hands, is able to feel and move objects by controlling another person's hand via a brain implant. The technique might one day even allow us to experience another person's body over long distances. Keith Thomas (right) was able to control another person's hand A man with paralysis has been able to move and sense another person's hand as if it were his own, thanks to a new kind of "telepathic" brain implant. "We created a mind-body connection between two different individuals," says Chad Bouton at the Feinstein Institutes for Medical Research in New York state. The approach could be used as a form of rehabilitation after spinal cord injury, allowing people with paralysis to work together, and may one day even allow people to share experiences remotely, says Bouton.

We present a framework for characterizing neurosis in embodied AI: behaviors that are internally coherent yet misaligned with reality, arising from interactions among planning, uncertainty handling, and aversive memory. In a grid navigation stack we catalogue recurrent modalities including flip-flop, plan churn, perseveration loops, paralysis and hypervigilance, futile search, belief incoherence, tie break thrashing, corridor thrashing, optimality compulsion, metric mismatch, policy oscillation, and limited-visibility variants. For each we give lightweight online detectors and reusable escape policies (short commitments, a margin to switch, smoothing, principled arbitration). We then show that durable phobic avoidance can persist even under full visibility when learned aversive costs dominate local choice, producing long detours despite globally safe routes. Using First/Second/Third Law as engineering shorthand for safety latency, command compliance, and resource efficiency, we argue that local fixes are insufficient; global failures can remain. To surface them, we propose genetic-programming based destructive testing that evolves worlds and perturbations to maximize law pressure and neurosis scores, yielding adversarial curricula and counterfactual traces that expose where architectural revision, not merely symptom-level patches, is required.

Health Medicine Researchers successfully heal rats' broken spines A new study paves the way toward developing a treatment for spinal cord injuries. Breakthroughs, discoveries, and DIY tips sent every weekday. There is currently no way to completely reverse the damage and paralysis that results from a spinal cord injury. One of the biggest obstacles is that neurons die and can't regrow across the damage. Now, researchers have developed a biomedical structure that has given impressive functional recovery to lab rats with severed spinal cords.

People with paralysis can now have their thoughts turned into speech just by imagining talking in their heads. While brain-computer interfaces can already decode the neural activity of people with paralysis when they physically attempt speaking, this can require a fair amount of effort. So Benyamin Meschede-Krasa at Stanford University and his colleagues sought a less energy-intensive approach. Take control of your brain's master switch to optimise how you think "We wanted to see whether there were similar patterns when someone was simply imagining speaking in their head," he says. "And we found that this could be an alternative, and indeed, a more comfortable way for people with paralysis to use that kind of system to restore their communication."

Brain-computer interface startup Paradromics today announced that surgeons successfully inserted the company's brain implant into a patient and safely removed it after about 10 minutes. It's a step toward longer trials of the device, dubbed Connexus. It's also the latest commercial development in a growing field of companies--including Elon Musk's Neuralink--aiming to connect people's brains directly to computers. With the Connexus, Austin-based Paradromics is looking to restore speech and communication in people with spinal cord injury, stroke, or amyotrophic lateral sclerosis, also known as ALS. The device is designed to translate neural signals into synthesized speech, text, and cursor control.

First Neuralink brain implant patient Noland Arbaugh discusses his paralysis, his implant and more on'The Will Cain Show.' Elon Musk's Neuralink brain implants are designed to help individuals with disabilities -- and the implant's first user told Fox News on Friday about the revolutionary technology. Arizona native Noland Arbaugh, the first Neuralink brain implant patient, joined "The Will Cain Show" to discuss how the device has helped him regain control of his life. "I'm just beyond grateful," Arbaugh told Fox News host Will Cain. "It's an incredible privilege to be a part of this." Elon Musk shows off his t-shirt reading "Tech Support" while speaking at the first Cabinet meeting hosted by U.S. President Donald Trump, at the White House in Washington, D.C., Feb. 26, 2025.

People with paralysis can control robotic devices through thought alone. Researchers at UC San Francisco have achieved a remarkable breakthrough in brain-computer interface (BCI) technology, enabling individuals with paralysis to control robotic devices through thought alone. This innovation combines artificial intelligence (AI) with neuroscience, allowing a paralyzed man to manipulate a robotic arm by imagining movements, a feat that marks a significant milestone in restoring autonomy to people with severe motor impairments. The device, known as a brain-computer interface (BCI), represents a fusion of advanced AI and neural engineering. BCIs have previously struggled to maintain functionality over extended periods, often losing effectiveness after just one or two days.

Neurotech company Synchron has unveiled the latest version of its brain-computer interface, which uses Nvidia technology and the Apple Vision Pro to enable individuals with paralysis to control digital and physical environments with their thoughts. In a video demonstration at the Nvidia GTC conference this week in San Jose, California, Synchron showed off how its system allows one of its trial participants, Rodney Gorham, who is paralyzed, to control multiple devices in his home. From his sun-filled living room in Melbourne, Australia, Gorham is able to play music from a smart speaker, adjust the lighting, turn on a fan, activate an automatic pet feeder, and run a robotic vacuum. Gorham has lost the use of his voice and much of his body due to having amyotrophic lateral sclerosis, or ALS. The degenerative disease weakens muscles over time and eventually leads to paralysis.
