AI enables paralyzed man to control robotic arm with brain signals

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 brain-computer interface: A new era of control

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. However, the newly developed BCI has set a record by functioning seamlessly for seven months without requiring major adjustments.

The key lies in the AI model’s ability to adapt to subtle changes in brain activity over time. As individuals repeatedly imagine movements, the AI refines its understanding of these neural signals, enabling more precise control of robotic devices. Dr. Karunesh Ganguly, neurologist and professor at UCSF, emphasized that this adaptive learning between humans and AI is critical for achieving lifelike functionality in neuroprosthetics.

Understanding brain changes: The science behind the breakthrough

Dr. Ganguly’s research revealed that while the shape of brain activity representations remains consistent, their locations shift slightly from day to day. This discovery explains why previous BCIs quickly lost their ability to interpret neural signals accurately.

To address this challenge, Ganguly and his team studied a participant who had been paralyzed by a stroke years earlier. Sensors implanted on the surface of his brain recorded neural signals as he imagined movements like grasping or lifting objects. Over two weeks, these signals were used to train the AI model to account for daily shifts in brain activity patterns.

From virtual practice to real-world success

Initially, the participant practiced controlling a virtual robotic arm that provided feedback on his imagined movements. This training helped refine his ability to visualize precise actions. Once he transitioned to using a real robotic arm, he quickly mastered tasks such as picking up blocks, opening cabinets and even holding a cup under a water dispenser.

Months later, the participant retained his ability to control the robotic arm with minimal recalibration, highlighting the long-term reliability of this BCI system.

Implications for people with paralysis

This groundbreaking technology has profound implications for individuals with paralysis. Tasks like feeding oneself or accessing water independently could drastically improve quality of life. Dr. Ganguly is optimistic about refining the AI further to enhance speed and fluidity in movement while testing the system in home environments.

TikTok ban: all the news on the app’s shutdown and return in the US

TikTok ban: all the news on the app’s shutdown and return in the US

After briefly going dark in the US to comply with the divest-or-ban law targeting ByteDance that went into effect on January 19th, TikTok quickly came back online. It eventually reappeared in the App Store and Google Play as negotiations between the US and China continued, and Donald Trump continued to sign extensions directing officials not to apply the law’s penalties.

Finally, in mid-December, TikTok CEO Shou Zi Chew told employees that the agreements to create TikTok USDS Joint Venture LLC, which includes Oracle, Silver Lake, and MGX as part owners, have been signed, and the deal is expected to close on January 22nd, 2026. His letter said that for users in the US, the new joint venture will oversee data protection, the security of a newly-retrained algorithm, content moderation, and the deployment of the US app and platform.

Read on for all the latest news on the TikTok ban law in the US.

Secret phrases to get you past AI bot customer service

Secret phrases to get you past AI bot customer service

NEWYou can now listen to Fox News articles!

You’re gonna love me for this. 

Say you’re calling customer service because you need help. Maybe your bill is wrong, your service is down or you want a refund. Instead of a person, a cheerful AI voice answers and drops you into an endless loop of menus and misunderstood prompts. Now what?  

That’s not an accident. Many companies use what insiders call “frustration AI.” The system is specifically designed to exhaust you until you hang up and walk away.

Not today.  (Get more tips like this at GetKim.com)

FOX NEWS POLL: VOTERS SAY GO SLOW ON AI DEVELOPMENT — BUT DON’T KNOW WHO SHOULD STEER

Here are a few ways to bypass “frustration” AI bots. (Sebastian Kahnert/picture alliance via Getty Images)

Use the magic words

You want a human. For starters, don’t explain your issue. That’s the trap. You need words the AI has been programmed to treat differently.

Nuclear phrases: When the AI bot asks why you’re calling, say, “I need to cancel my service” or “I am returning a call.” The word cancel sets off alarms and often sends you straight to the customer retention team. Saying you’re returning a call signals an existing issue the bot cannot track. I used that last weekend when my internet went down, and, bam, I had a human.

Power words: When the system starts listing options, clearly say one word: “Supervisor.” If that doesn’t work, say, “I need to file a formal complaint.” Most systems are not programmed to deal with complaints or supervisors. They escalate fast.

Technical bypass: Asked to enter your account number? Press the pound key (#) instead of numbers. Many older systems treat unexpected input as an error and default to a human.

Go above the bots

If direct commands fail with AI, be a confused human.

The Frustration Act: When the AI bot asks a question, pause. Wait 10 seconds before answering. These systems are built for fast, clean responses. Long pauses often break the flow and send your call to a human.

The Unintelligible Bypass: Stuck in a loop? Act like your phone connection is terrible. Say garbled words or nonsense. After the system says, “I’m having trouble understanding you” three times, many bots automatically transfer you to a live agent.

The Language Barrier Trick: If the company offers multiple languages, choose one that’s not your primary language or does not match your accent. The AI often gives up quickly and routes you to a human trained to handle language issues.

Use these tricks when you need help. You are calling for service, not an AI bot.

The latest iPad Air is $400 for the first time and arrives by Christmas

The latest iPad Air is 0 for the first time and arrives by Christmas

If you have $400 and want an iPad, your options are usually kind of limited to either just the base iPad, or better yet, the latest iPad Mini — if it happens to be on sale when you’re shopping (it is now, but that’s not always the case). But right now, you should consider getting the 128GB version of Apple’s 11-inch iPad Air with the capable M3 processor. At Target, multiple colors of this model are $399.99, beating the previous low of $449.99 we’ve seen during large-scale deal events. Currently, no other retailer is matching this price. This sale ends Saturday night.

$400 is a sweet price for this model, as it debuted in early 2025 for $600. In terms of how it stacks up to other iPad models, Verge editor-at-large David Pierce said in his impressions that the M3 Air is “exactly what you think it is. Which is fine.” I know, that sounds like a back-handed compliment, but it’s been a while since iPads peaked in terms of utility, design, and fast performance. This one carries the torch in Apple’s tablet dominance, and its M3 processor means it’ll be a fantastic tablet for longer than any other iPad at the $400 price point. Read our in-depth impressions.
