Dr. Joshua Bederson places Precision Neuroscience’s electrodes onto a brain.

As the lights dimmed in an operating room at The Mount Sinai Hospital in New York City, Dr. Joshua Bederson prepared to make history.
Bederson, system chair for the Department of Neurosurgery at Mount Sinai Health System, is no stranger to long hours in an operating room. The former competitive gymnast has completed more than 6,500 procedures in his career, and he said he visualizes the steps for each one as if he’s rehearsing for a routine.
On this particular morning in April, Bederson was readying for a meningioma resection case, which meant he would be removing a benign brain tumor. Bederson said his primary focus is always on caring for the patient, but in some cases, he also gets to help advance science.
This procedure was one such case.
A small crowd gathered as Bederson took his seat in the operating room, his silhouette aglow from the bright white light shining on the patient in front of him. Health-care workers, scientists and CNBC craned forward – some peering through windows – to watch as Bederson placed four electrode arrays from Precision Neuroscience onto the surface of the patient’s brain for the first time.
An electrode is a small sensor that can detect and carry an electrical signal, and an array is a grid of electrodes. Neurosurgeons use electrodes during some procedures to help monitor and avoid important parts of the brain, like areas that control speech and movement.
Precision is a three-year-old startup building a brain-computer interface, or a BCI. A BCI is a system that decodes neural signals and translates them into commands for external technologies. Perhaps the best-known company in the field is Neuralink, which is owned by Tesla and SpaceX CEO Elon Musk.
Other companies like Synchron and Paradromics have also developed BCI systems, though their goals and designs all vary. The first application of Precision’s system will be to help patients with severe paralysis restore functions like speech and movement, according to its website.

Precision’s flagship BCI is called the Layer 7 Cortical Interface. It’s a microelectrode array that’s thinner than a human hair, and it resembles a piece of yellow scotch tape. Each array is made up of 1,024 electrodes, and Precision says it can conform to the brain’s surface without damaging any tissue.
When Bederson used four of the company’s arrays during the surgery in April, he set a record for the highest number of electrodes to be placed on the brain in real-time, according to Precision. But perhaps more importantly, the arrays were able to detect signals from the patient’s individual fingers, which is a far greater amount of detail than standard electrodes are able to capture.
Using Precision’s electrode array is like turning a pixilated, low-resolution image into a 4K image, said Ignacio Saez, an associate professor of neuroscience, neurosurgery and neurology at the Icahn School of Medicine at Mount Sinai. Saez and his team oversee Precision’s work with Mount Sinai.
“Instead of having 10 electrodes, you’re giving me 1,000 electrodes,” Saez told CNBC in an interview. “The depth and the resolution and the detail that you’re going to get are completely different, even though they somehow reflect the same underlying neurological activity.”
Bederson said accessing this level of detail could help doctors be more delicate with their surgeries and other interventions in the future. For Precision, the ability to record and decode signals from individual fingers will be crucial as the company works to eventually help patients restore fine motor control.
The data marks a milestone for Precision, but there’s a long road ahead before it achieves some of its loftier goals. The company is still working toward approval from the U.S. Food and Drug Administration, and it has yet to implant a patient with a more permanent version of its technology.
“I think these are little baby steps towards the ultimate goal of brain-computer interface,” Bederson told CNBC in an interview.

Bederson’s surgery in April was not Precision’s first rodeo. In fact, it marked the 14th time that the company has placed its array on a human patient’s brain.
Precision has been partnering with academic medical centers and health systems to perform a series of first-in-human clinical studies. The goal of each study varies, and the company announced its collaboration with Mount Sinai in March.
At Mount Sinai, Precision is exploring different applications for its array in clinical settings, like how it can be used to help monitor the brain during surgery. In these procedures, surgeons like Bederson temporarily place Precision’s array onto patients who are already undergoing brain surgery for a medical reason.
Patients give their consent to participate beforehand.
It’s routine for neurosurgeons to map brain signals with electrodes during these types of procedures. Bederson said the current accepted practice is to use anywhere between four to almost 100 electrodes – a far cry from the 4,096 electrodes he was preparing to test.

Precision’s arrays are in use for a short portion of these surgeries, so CNBC joined the operating room in April once the procedure was already underway.
The patient, who asked to remain anonymous, was asleep. Bederson’s team had already removed part of their skull, which left an opening about the size of a credit card. Four of Precision’s arrays were carefully laid out on a table nearby.
Once the patient was stabilized, Precision’s employees trickled into the operating room. They helped affix the arrays in an arc around the opening on the patient’s head, and connected bundles of long blue wires at the other end to a cart full of equipment and monitors.
Dr. Benjamin Rapoport, Precision’s co-founder and chief scientific officer, quietly looked on. Every major procedure presents some risks, but the soft-spoken neurosurgeon’s calm demeanor never wavered. He told CNBC that each new case is just as exciting as the last, especially since the company is still learning.

Bederson entered the operating room as Precision’s preparations neared their end. He helped make some final tweaks to the set up, and the overhead lights in the operating room were turned off.
Ongoing chatter quieted to hushed whispers. Bederson was ready to get started.
He began by carefully pulling back a fibrous membrane called the dura to reveal the surface of the brain. He laid a standard strip of electrodes onto the tissue for a few minutes, and then it was time to test Precision’s technology.
Using a pair of yellow tweezers called long bayonet forceps, Bederson began placing all four of Precision’s electrode arrays onto the patient’s brain. He positioned the first two arrays with ease, but the last two proved slightly more challenging.
Bederson was working with a small section of brain tissue, which meant the arrays needed to be angled just right to lay flat. For reference, imagine arranging the ends of four separate tape measures within a surface area roughly the size of a rubber band. It took a little reconfiguring, but after a couple of minutes, Bederson made it happen.
Real-time renderings of the patient’s brain activity swept across Precision’s monitors in the operating room. All four arrays were working.
In an interview after the surgery, Bederson said it was “complicated” and “a little bit awkward” to place all four arrays at once. From a design perspective, he said two arrays with twice as many points of contact, or longer arrays with greater spacing would have been helpful.
Bederson compared the arrays to spaghetti, and the description was apt. From where CNBC was watching, it was hard to tell where one stopped and the next began.
Once all the arrays were placed and actively detecting signals, Precision’s Rapoport stood with his team by the monitors to help oversee data collection. He said the research is the product of a true team effort from the company, the health system and the patient, who often doesn’t get to see the benefits of the technology at this stage.
“It takes a village to make this sort of thing move forward,” Rapoport said.
CNBC left the operating room as Bederson began removing the tumor, but he said the case went well. The patient woke up afterward with some weakness in their foot since the surgery was within that part of the brain, but Bederson said he expected the foot would recover in around three to four weeks.

Rapoport was present at this particular surgery because of his role with Precision, but he’s well acquainted with the operating rooms at Mount Sinai.
Rapoport is a practicing surgeon and serves as an assistant professor of neurosurgery at the Icahn School of Medicine at Mount Sinai. Rapoport reports to Bederson, and Bederson said the pair have known one another since Rapoport was in residency at Weill Cornell Medicine.
Dr. Thomas Oxley, the CEO of the competing BCI company Synchron, is also a faculty member under Bederson. Synchron has built a stent-like BCI that can be inserted through a patient’s blood vessels. As of early February, the company had implanted its system into 10 human patients. It is also working toward FDA approval.
Bederson has an equity stake in Synchron, but he told CNBC he didn’t realize how much it would prevent him from participating in research with the Synchron team. He has no monetary investment in Precision.
“I really did not want to have any financial interest in Precision because I think it has an equally promising future and wanted to advance the science as fast as I could,” Bederson said.
Rapoport also helped co-found Musk’s Neuralink in 2017, though he departed the company the following year. Neuralink is building a BCI designed to be inserted directly into the brain tissue, and the company recently received approval to implant its second human patient, according to a report from The Wall Street Journal on Monday.
As the BCI industry heats up, Bederson said the amount that scientists understand about the brain is poised to “explode” over the next several years. Companies like Precision are just getting started.

“I really feel like the future is where the excitement is,” Bederson said.
Rapoport said Precision is hoping to receive FDA approval for the wired version of its system “within a few months.” This version, which is what CNBC saw in the operating room, would be for use in a hospital setting or monitored care unit for up to 30 days at a time, he said.
Precision’s permanent implant, which will transmit signals wirelessly, will go through a separate approval process with the FDA.
Rapoport said Precision hopes to implant “a few dozen” patients with the wired version of its technology by the end of the year. That data collection would give the company a “very high level of confidence” in its ability to decode movement and speech signals in real-time, he said.
“Within a few years, we’ll have a much more advanced version of the technology out,” Rapoport said.
Qwen3 is Alibaba’s debut into so-called “hybrid reasoning models,” which it says combines traditional LLM capabilities with “advanced, dynamic reasoning.”

Alibaba released the next generation of its open-sourced large language models, Qwen3, on Tuesday — and experts are calling it yet another breakthrough in China’s booming open-source artificial intelligence space.
In a blog post, the Chinese tech giant said Qwen3 promises improvements in reasoning, instruction following, tool usage and multilingual tasks, rivaling other top-tier models such as DeepSeek’s R1 in several industry benchmarks.
The LLM series includes eight variations that span a range of architectures and sizes, offering developers flexibility when using Qwen to build AI applications for edge devices like mobile phones.
Qwen3 is also Alibaba’s debut into so-called “hybrid reasoning models,” which it says combines traditional LLM capabilities with “advanced, dynamic reasoning.”
According to Alibaba, such models can seamlessly transition between a “thinking mode” for complex tasks such as coding and a “non-thinking mode” for faster, general-purpose responses.
“Notably, the Qwen3-235B-A22B MoE model significantly lowers deployment costs compared to other state-of-the-art models, reinforcing Alibaba’s commitment to accessible, high-performance AI,” Alibaba said.
The new models are already freely available for individual users on platforms like Hugging Face and GitHub, as well as Alibaba Cloud’s web interface. Qwen3 is also being used to power Alibaba’s AI assistant, Quark.
China’s AI advancement
AI analysts told CNBC that the Qwen3 represents a serious challenge to Alibaba’s counterparts in China, as well as industry leaders in the U.S.
In a statement to CNBC, Wei Sun, principal analyst of artificial intelligence at Counterpoint Research, said the Qwen3 series is a “significant breakthrough—not just for its best-in-class performance” but also for several features that point to the “application potential of the models.”
Those features include Qwen3’s hybrid thinking mode, its multilingual support covering 119 languages and dialects and its open-source availability, Sun added.
Open-source software generally refers to software in which the source code is made freely available on the web for possible modification and redistribution. At the start of this year, DeepSeek’s open-sourced R1 model rocked the AI world and quickly became a catalyst for China’s AI space and open-source model adoption.
“Alibaba’s release of the Qwen 3 series further underscores the strong capabilities of Chinese labs to develop highly competitive, innovative, and open-source models, despite mounting pressure from tightened U.S. export controls,” said Ray Wang, a Washington-based analyst focusing on U.S.-China economic and technology competition.
According to Alibaba, Qwen has already become one of the world’s most widely adopted open-source AI model series, attracting over 300 million downloads worldwide and more than 100,000 derivative models on Hugging Face.
Wang said that this adoption could continue with Qwen3, adding that its performance claims may make it the best open-source model globally — though still behind the world’s most cutting-edge models like OpenAI’s o3 and o4-mini.
Chinese competitors like Baidu have also rushed to release new AI models after the emergence of DeepSeek, including making plans to shift toward a more open-source business model.
Meanwhile, Reuters reported in February that DeepSeek is accelerating the launch of its successor to its R1, citing anonymous sources.
“In the broader context of the U.S.-China AI race, the gap between American and Chinese labs has narrowed—likely to a few months, and some might argue, even to just weeks,” Wang said.
“With the latest release of Qwen 3 and the upcoming launch of DeepSeek’s R2, this gap is unlikely to widen—and may even continue to shrink.”
Uber on Monday informed employees, including some who had been previously approved for remote work, that it will require them to come to the office three days a week, CNBC has learned.
“Even as the external environment remains dynamic, we’re on solid footing, with a clear strategy and big plans,” CEO Dara Khosrowshahi told employees in the memo, which was viewed by CNBC. “As we head into this next chapter, I want to emphasize that ‘good’ is not going to be good enough — we need to be great.”
Khosrowshahi goes on to say employees need to push themselves so the company “can move faster and take smarter risks” and outlined several changes to Uber’s work policy.
Uber in 2022 established Tuesdays and Thursdays as “anchor days” where most employees must spend at least half of their work time in the company’s office. Starting in June, employees will be required in the office Tuesday through Thursday, according to the memo.
That includes some employees who were previously approved to work remotely. The company said it had already informed impacted remote employees.
“After a thorough review of our existing remote approvals, we’re asking many remote employees to come into an office,” Khosrowshahi wrote. “In addition, we’ll hire new remote roles only very sparingly.”
The company also changed its one-month paid sabbatical program, according to the memo. Previously, employees were eligible for the sabbatical after five years at the company. That’s now been raised to eight years, according to the memo.
“This program was created when Uber was a much younger company, and when reaching 5 years of tenure was a rare feat,” Khosrowshahi wrote. “Back then, we were in the office five (sometimes more!) days of a week and hadn’t instituted our Work from Anywhere benefit.”
Khosrowshahi said the changes will help Uber move faster.
“Our collective view as a leadership team is that while remote work has some benefits, being in the office fuels collaboration, sparks creativity, and increases velocity,” Khosrowshahi wrote.
The changes come as more companies in the tech industry cut costs to appease investors after over-hiring during the Covid-19 pandemic. Google recently began demanding that employees who were previously-approved for remote work also return to the office if they want to keep their jobs, CNBC reported last week.
Last year, Khosrowshahi blamed remote work for the loss of its most loyal customers, who would take ride-sharing as their commute to work.
“Going forward, we’re further raising this bar,” Khosrowshahi’s Monday memo said. “After a thorough review of our existing remote approvals, we’re asking many remote employees to come into an office. In addition, we’ll hire new remote roles only very sparingly.”
Uber’s leadership team will monitor attendance “at both team and individual levels to ensure expectations are being met,” Khosrowshahi wrote.
Following the memo, Uber employees immediately swarmed the company’s internal question-and-answer forum, according to correspondence viewed by CNBC. Khosrowshahi said he and Nikki Krishnamurthy, the company’schief people officer, will hold an all-hands meeting on Tuesday to discuss the changes.
Many employees asked leadership to reconsider the sabbatical change, arguing that the company should honor the original eligibility policy.
“This isn’t ‘doing the right thing’ for your employees,” one employee commented.
Uber did not immediately respond to a request for comment.
A United Launch Alliance Atlas V rocket is on the launch pad carrying Amazon’s Project Kuiper internet network satellites, which are expected to eventually rival Elon Musk’s Starlink system, at the Cape Canaveral Space Force Station in Cape Canaveral, Florida, U.S., April 9, 2025.

Amazon on Monday launched the first batch of its Kuiper internet satellites into space after an earlier attempt was scrubbed due to inclement weather.
A United Launch Alliance rocket carrying 27 Kuiper satellites lifted off from a launchpad at the Cape Canaveral Space Force Station in Florida shortly after 7 p.m. eastern, according to a livestream.
“We had a nice smooth countdown, beautiful weather, beautiful liftoff, and Atlas V is on its way to orbit to take those 27 Kuiper satellites, put them on their way and really start this new era in internet connectivity,” Caleb Weiss, a systems engineer at ULA, said on the livestream following the launch.
The satellites are expected to separate from the rocket roughly 280 miles above Earth’s surface, at which point Amazon will look to confirm the satellites can independently maneuver and communicate with its employees on the ground.
Six years ago Amazon unveiled its plans to build a constellation of internet-beaming satellites in low Earth orbit, called Project Kuiper. The service will compete directly with Elon Musk’s Starlink, which currently dominates the market and has 8,000 satellites in orbit.
The first Kuiper mission kicks off what will need to become a steady cadence of launches in order for Amazon to meet a deadline set by the Federal Communications Commission. The agency expects the company to have half of its total constellation, or 1,618 satellites, up in the air by July 2026.
Amazon has booked more than 80 launches to deploy dozens of satellites at a time. In addition to ULA, its launch partners include Musk’s SpaceX (parent company of Starlink), European company Arianespace and Jeff Bezos’ space exploration startup Blue Origin.
Amazon is spending as much as $10 billion to build the Kuiper network. It hopes to begin commercial service for consumers, enterprises and government later this year.
In his shareholder letter earlier this month, Amazon CEO Andy Jassy said Kuiper will require upfront investment at first, but eventually the company expects it to be “a meaningful operating income and ROIC business for us.” ROIC stands for return on invested capital.
Investors will be listening for any commentary around further capex spend on Kuiper when Amazon reports first-quarter earnings after the bell on Thursday.
