Rice-sized robot could make brain surgery safer and less invasive

A French startup named Robeauté has just raised about $29 million to develop a truly groundbreaking neurosurgical microrobot. 

Imagine a device no bigger than a grain of rice that can carefully navigate the complex and delicate pathways of the brain. 

This little robot could change the way doctors treat brain tumors and other neurological conditions, making surgeries safer and more precise than ever before.

The challenges of brain surgery today

Brain surgery is incredibly complex. The tools surgeons use today are often rigid and can only move in straight lines. This limits where they can safely operate. Many tumors or problematic areas in the brain are simply too risky to reach because they lie near regions responsible for critical functions like movement or speech.

In some cases, surgeons have no choice but to leave tumors untreated because the risk of damage is too high. On top of that, many drugs cannot even reach certain parts of the brain because of the blood-brain barrier, leaving patients with limited treatment options.

How the microrobot works

Robeauté’s microrobot is designed to overcome these challenges. It is incredibly small, about three millimeters long, roughly the size of a grain of rice, and it enters the brain through a tiny incision just a millimeter wide. Unlike traditional tools, this robot does not move in straight lines. Instead, it can follow curved paths, gently pushing aside brain tissue as it goes. It uses rotating silicone rings at its tip to carefully shift tissue without causing damage. This movement is inspired by how tiny insects walk on water, using adhesion forces that dominate at such small scales.

Inside the robot, there is a small compartment that holds miniature surgical tools. For example, when performing a biopsy, the microrobot uses a flexible needle and tiny forceps to collect tissue samples. These samples can be stored inside the device or pulled back through a cable connected to the robot. Beyond biopsies, the robot can also implant electrodes for conditions like Parkinson’s disease or deliver drugs directly to tumors. It even has sensors that send real-time information back to the surgeons, helping them monitor the procedure closely.

What is really impressive is how the robot’s path is planned. Using MRI scans combined with artificial intelligence, surgeons can map out safe routes that avoid sensitive brain areas. During surgery, they can adjust the robot’s position in real time using ultrasound imaging mounted on the skull, achieving sub-millimeter precision.

Looking ahead: Trials and future plans

So far, the microrobot has been tested in preclinical trials, mainly on sheep, with very promising results. There were no major complications like bleeding, which suggests the device can safely navigate brain tissue. Robeauté plans to begin human clinical trials in 2026, focusing on microbiopsies of brain tumors. They also aim to expand into the U.S. market and seek FDA approval, with hopes of launching internationally by 2030.

Why this technology matters

The potential impact of this microrobot is huge. It could allow doctors to diagnose brain tumors earlier and treat them more effectively while reducing the risks associated with traditional surgery. Because it is minimally invasive, patients could experience faster recoveries and fewer side effects. Additionally, the ability to collect live data from inside the brain could accelerate research and drug development for neurodegenerative diseases like Alzheimer’s and Parkinson’s.

Kurt’s key takeaways

Robeauté’s microrobot represents an exciting fusion of robotics, artificial intelligence, biology, and medicine. It tackles one of the most difficult challenges in healthcare: how to safely access and treat the brain. While there are still hurdles to overcome, such as regulatory approvals and manufacturing at scale, this tiny device has the potential to turn previously “inoperable” brain tumors into treatable conditions. As one of the company’s founders describes it, the microrobot acts like a “brain gardener,” delicately tending to damaged tissue from within. With strong funding and a growing portfolio of patents, Robeauté is poised to make a lasting impact on the future of neurosurgery.

It’s amazing how good Alienware’s $350 OLED monitor is

It’s amazing how good Alienware’s 0 OLED monitor is

I’ve recommended several OLED gaming monitors to readers over the years, and I’ve finally taken my own advice to buy one. Alienware’s new 27-inch 1440p QD-OLED has all the features that I want and a low $350 price that was too tempting to ignore.

The AW2726DM model has five things that make it stand out for the price: a 1440p QD-OLED screen with lush contrast, a fast 240Hz refresh rate, a semi-glossy screen coating to enhance details, a low-profile design without flashy RGB LEDs, and a great warranty (three years with coverage for burn-in).

I’ve been using Alienware’s new monitor for a couple days, and I’ve already spent hours with it playing Marathon. It was my first opportunity to see Bungie’s new first-person extraction shooter in its full HDR glory, and I can never go back. Switching on HDR wasn’t automatic, though it already looked so much better than my IPS panel without being activated.

Enabling it transformed how Marathon looked for the better, but made everything else about the OS look pretty washed-out. It’s a Windows issue, not an Alienware issue. It’s easy to enable HDR every time I launch a game and disable it afterward with the Windows + Alt + B keyboard shortcut, but unfortunately triggers HDR for all connected displays. This includes my IPS monitor that imbues everything with a terrible gray hue when HDR is on. So, using the system settings is the best way to adjust HDR for just the QD-OLED.

I landed on this QD-OLED after having spent a ton of time researching pricier models. The unanimous takeaway from reviewers was that LG’s Tandem RGB WOLED panels are some of the brightest out there, but also tend to exhibit lousy gray uniformity in dark scenes. QD-OLED monitors, on the other hand, offer slightly better contrast than WOLED and don’t suffer from those same uniformity issues. However, blacks sometimes appear as dark purple in bright rooms on QD-OLED panels, meaning they’re ideal for rooms that don’t have a bunch of light bouncing around.

There’s no perfect choice, and honestly I got tired of doing research, so I jumped in with the cheapest OLED. I’m glad that I did. Shopping for an OLED gaming monitor can be hard, but it can also be this easy. AOC makes a model that’s discounted to $339.99 at the time of publishing, and its specs are comparable.

As expected, the AW2726DM isn’t a cutting-edge monitor. Its QD-OLED panel isn’t as fast or as bright as some other pricier options, and it doesn’t have USB ports for connecting accessories. Considering its low price, it’s easy for me to overlook those omissions. I’d have a much harder time accepting them in a pricier display.

The fact that I mostly use my computer for text-based work at The Verge is what prevented me from upgrading to an OLED monitor. My 1440p IPS monitor is bright, it’s good at showing text clearly, and it has a fast refresh rate for gaming. Alienware’s QD-OLED is less bright, and some might be bothered by how text looks (I have to really squint to see the slight fringing from this QD-OLED’s subpixel layout). But I have a life outside of work, which includes playing a lot of PC games. That’s the slice of myself I bought this monitor for, and I’m so happy I did.

Michael and Susan Dell surpass  billion in donations backing AI-driven hospital project

NEWYou can now listen to Fox News articles!

Billionaire Michael Dell and his wife, Susan Dell, have become the first donors to give more than $1 billion to the University of Texas at Austin, funding a massive new medical research campus and hospital system powered by artificial intelligence.

The couple’s latest investment includes a $750 million gift to help build the UT Dell Medical Center, a planned “AI-native” hospital expected to open in 2030 as part of a more than 300-acre advanced research campus.

University officials said the project will integrate research, clinical care and advanced computing to improve early disease detection, personalize treatment and expand access to care in the rapidly growing Austin region.

The Dells’ support builds on decades of contributions to UT, including funding for its medical school, scholarships and research programs.

“By bringing together medicine, science and computing in one campus designed for the AI era, UT can create more opportunity, deliver better outcomes, and build a stronger future for communities across Texas and beyond,” Michael Dell and Susan Dell said.

The gift ranks among the largest in the history of higher education, alongside major contributions like Phil Knight’s $2 billion pledge to Oregon Health & Science University and Michael Bloomberg’s $1.8 billion donation to Johns Hopkins University.

The new UT Dell Medical Center will be developed in collaboration with MD Anderson Cancer Center, integrating cancer care into a system designed to connect prevention, diagnosis and treatment.

“We will deliver better outcomes for patients by providing research-driven cancer care that is precise, compassionate and hope-filled,” Peter WT Pisters, president of UT MD Anderson, said.

Officials said the facility will be built from the ground up to incorporate AI, rather than retrofitting older infrastructure — an approach they say could transform how hospitals operate.

Independent experts have cautioned that AI in health care can introduce risks if not carefully validated. A widely cited study published in the journal Science by researchers at the University of California, Berkeley and the University of Chicago found that a commonly used healthcare algorithm underestimated the needs of Black patients due to biased training data, highlighting broader concerns about equity in AI-driven systems.
