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.

Use this map to find the data centers in your backyard
When Oregon resident Isabelle Reksopuro heard Google was gobbling up public land to fuel its data centers in her home state, she didn’t initially know what to believe. “There’s a lot of misinformation about data centers,” she said. “Google has denied taking that land.”
Technically, she explains, The Dalles, a city near the Washington state border, sought to reclaim that land, “and Google is just a big, unnamed power user.” The city had in fact asked for ownership of a 150-acre portion of Mount Hood National Forest, claiming it needs access to Mount Hood’s watershed to meet municipal needs as its population — 16,010 as of the 2020 census — grows. But critics, including environmentalists, say the city is trying to secure more water for Google, which has a sprawling data center campus in The Dalles that already consumes about one-third of the city’s water supply.
This controversy made Reksopuro curious about the backlash to data centers being built in other communities. So Reksopuro, a student at the University of Washington who studies the connections between tech and public policy, decided to map it out. Using information collected by Epoch AI and data scraped from legislation on data centers, she built an interactive map tracking AI policy around the world. She designed it to be simple enough for anyone to use. “I wanted it to be something that my younger sisters could play through and explore to understand what are the data centers in the area and what’s actually being done about it,” Reksopuro said. She hoped to shift their opinions that way, “instead of like, through TikTok.”
Four times a day, the map searches for new sources and checks them against the existing database Reksopuro built out. “Once it does that, it will write a new summary, add it to the news feed, and populate it on the sidebar,” she said. “I wanted it to be self-updating, since I’m also a student.”
Reksopuro isn’t against data centers, but she thinks tech giants benefit from a lack of transparency around data center policies. “Right now, it’s this really opaque thing — and all of a sudden, there’s a facility,” she said. “I think that if people knew about data centers beforehand, it would give them leverage. They would be able to negotiate: ask for job training programs, tax revenue, environmental monitoring, things to improve their community.”

Microsoft’s Edge Copilot update uses AI to pull information from across your tabs
Microsoft Edge is adding a new feature that will allow its Copilot AI chatbot to gather information from all of your open tabs. When you start a conversation with Copilot, you can ask the chatbot questions about what’s in your tabs, compare the products you’re looking at, summarize your open articles, and more.
In its announcement, Microsoft says you can “select which experiences you want or leave off the ones you don’t.” The company is retiring Copilot Mode as well, which could similarly draw information from your tabs but offered some agentic features, like the ability to book a reservation on your behalf. Microsoft has since folded these agentic capabilities into its “Browse with Copilot” tool.
Several other AI features are coming to Edge, including an AI-powered “Study and Learn” mode that can turn the article you’re looking at into a study session or interactive quiz. There’s a new tool that turns your tabs into AI-powered podcasts as well, similar to what you’d find on NotebookLM, and an AI writing assistant that will pop up when you start entering text on a webpage.
You can also give Copilot permission to access your browsing history to provide more “relevant, high-quality answers,” according to Microsoft. Copilot in Edge on desktop and mobile will come with “long-term memory” as well, which can tailor its responses based on your previous conversations. And, when you open up a new tab, you’ll see a redesigned page that combines chat, search, and web navigation, along with the Journeys feature, which uses AI to organize your browsing history into categories that you can revisit.
Meanwhile, an update to Edge’s mobile app will allow you to share your screen with Copilot and talk through the questions about what you’re seeing. Microsoft says you’ll see “clear visual cues” when Copilot is active, “so you know when it’s taking an action, helping, listening, or viewing.”
