3D printed cornea restores sight in world first
NEWYou can now listen to Fox News articles!
Surgeons at Rambam Eye Institute have made medical history.
They restored sight to a legally blind patient using a fully 3D printed corneal implant grown entirely from cultured human corneal cells. This marked the first time a corneal implant that did not rely on donor tissue had ever been transplanted into a human eye.

A breakthrough that turns one donor cornea into hundreds
The cornea came from a healthy deceased donor and was then multiplied in the lab. Researchers used the cultured cells to print about 300 transparent implants with Precise Bio’s regenerative platform.
Their system builds a layered structure that looks and behaves like a natural cornea. It is designed to provide clarity, strength and long-term function.
HOW A TINY RETINAL IMPLANT IS HELPING PEOPLE REGAIN THEIR SIGHT
Since donor shortages prevent millions from receiving sight-saving care each year, this approach could transform access. Many patients in developed countries wait only a few days for a transplant, while others wait years due to low tissue availability. A single donor cornea that can create hundreds of implants changes that equation.

The surgery that proved it works
Professor Michael Mimouni, director of the Cornea Unit in the Department of Ophthalmology at Rambam Eye Institute, led the surgical team. He described the moment as unforgettable because the lab-grown implant restored sight to a real patient for the first time.
He says, “What this platform shows and proves is that in the lab, you can expand human cells. Then print them on any layer you need, and that tissue will be sustainable and work. We can hopefully reduce waiting times for all kinds of patients waiting for all kinds of transplants.”
The procedure is part of an ongoing Phase 1 clinical trial that assesses safety and tolerability in people with corneal endothelial disease. This achievement reflects years of work across research labs, operating rooms and industry. It also shows how coordinated teams can push new treatments from concept to clinical reality.
How the science fits into a bigger future
The breakthrough will have a permanent home in Rambam’s upcoming Helmsley Health Discovery Tower. The new Eye Institute will consolidate care, training and research under one roof. It aims to speed the move from emerging science to real-world treatment for patients across Northern Israel and beyond.
Precise Bio says its 3D printing system could eventually support other tissues like cardiac muscle, liver and kidney cells. That future will require long trials and extensive validation, but the path now looks more achievable.

What this means for you
If corneal disease affects someone in your family, this work brings new hope. Donor tissue may continue to play a role in many regions, but lab-grown implants offer a way to expand access where shortages hold patients back. The success of this first transplant also suggests a future where regenerative medicine supports many types of tissue repair.
This milestone also shows how long scientific breakthroughs take to reach real patients. The first 3D printed cornea design appeared in 2018 and only now reached human use. Even so, the progress feels fast when the result is restored sight.

Nothing cancels this year’s CMF phone due to RAM prices
Nothing’s next budget phone is the latest victim of RAMageddon. As 9to5Google reports, Nothing co-founder Akis Evangelidis announced in a post on X that a follow-up to the CMF Phone 2 Pro won’t be coming this year:
We were working on a successor but with memory prices where they are right now, we can’t build a phone that feels like a genuine step forward at a price that makes sense for CMF. As a result, we’ve decided not to launch a new CMF phone this year.
Last week, Nothing CEO and co-founder Carl Pei also said the RAM shortage has impacted the cost of the company’s mid-range phone, stating, “For Phone 4A, memory costs doubled between when we decided to build the device and when it launched. They’ve doubled again since.” According to Pei, “memory is now the most expensive component in a smartphone.” Nothing is far from the only company facing RAM pricing challenges — earlier this week, Tim Cook announced Apple will be raising prices, saying “the situation has become unsustainable.”
While there won’t be a new CMF phone this year, Evangelidis added in his post that CMF still has “several new products launching as well as some entirely new categories.” He also hinted that “the smartphone launch season at Nothing isn’t over yet.”

China’s brain chip breakthrough raises big questions
China approves world’s first commercial brain chip
Apple unveils new child safety tools, enabling parents to manage kid accounts, media access, communication, apps, and browsing. Tech companies like Meta, Roblox, YouTube and TikTok enhance safety with age verification, content moderation and time limits. China approves the world’s first commercial brain chip, raising privacy concerns.
NEWYou can now listen to Fox News articles!
A coin-sized brain chip in China could help people with paralysis control devices using their thoughts. China has approved a brain-computer interface called NEO for commercial medical use in certain patients with paralysis caused by spinal cord injuries. That moves brain-chip technology out of research trials and closer to real-world medical care.
Developed by researchers at Tsinghua University and Shanghai-based Neuracle Technology, NEO sits under the skull but rests on the brain’s protective outer layer rather than piercing deep into brain tissue. That design could make it less invasive than some competing implants.
For patients who have lost movement, this kind of technology could be life-changing. It could help restore a level of independence that once felt out of reach. But here’s where we need to slow down a bit. If a brain chip can turn your brain signals into digital commands, we need to ask who controls that data and how well it is protected.

BRAIN IMPLANT ENABLES ALS PATIENT TO COMMUNICATE USING AI

What is China’s NEO brain chip?
NEO is a brain-computer interface, often called a BCI. These systems read brain activity and translate it into commands for an external device. In this case, the implant uses sensors placed near the brain’s motor-control area. Those signals can help a patient operate equipment such as a robotic glove or computer interface.
What makes NEO especially notable is its placement. Brain-computer interfaces can be designed in different ways, and some go deeper into the brain than others. The company most people know in this space is Neuralink, the brain-chip startup co-founded by Elon Musk. Its implant uses tiny threads that enter the brain’s cortex. NEO takes a less invasive approach by placing electrodes on the dura mater, which is the protective membrane around the brain.
That design matters because every brain implant carries medical risk. Surgery can cause bleeding, swelling, infection or tissue damage. Even a small complication in the wrong part of the brain can affect speech or movement.
China’s approval does not mean brain chips are suddenly available for anyone who wants one. This remains a medical device for a narrow group of patients. Right now, the focus centers on helping people with severe paralysis regain some digital or assisted movement control.
Why China’s brain chip breakthrough matters
The medical upside here is hard to deny. More than three billion people worldwide live with neurological conditions, according to the World Health Organization. That includes people dealing with stroke, epilepsy, Parkinson’s disease, spinal cord injuries and other serious conditions.
For someone who has spent years unable to move freely or communicate easily, even a small amount of restored control could feel enormous. That is why brain-computer interfaces are getting so much attention. They could give some patients a new way to interact with the world around them.
Neuralink has already shown what that can look like in real life. Audrey Crews, a Neuralink trial participant who has been paralyzed for years, publicly shared that she wrote her name using the implant by controlling her computer.
ELON MUSK SHARES PLAN TO MASS-PRODUCE BRAIN IMPLANTS FOR PARALYSIS, NEUROLOGICAL DISEASE
How China’s brain chip compares with Neuralink
Elon Musk’s Neuralink has attracted most of the public attention in the U.S. brain-chip race. Musk has talked openly about restoring movement, helping people communicate and one day addressing vision loss.
Neuralink received approval to begin human trials, and more than 20 people have reportedly received its implant through testing. However, it has not received broad FDA approval for general commercial use.
China’s NEO approval puts a different kind of pressure on the field. It shows that China wants to move brain-computer interface technology into its health system and build a major industry around it.
This also fits a larger pattern. China has made BCI development part of its strategic technology push. The country wants breakthroughs by 2027 and a globally competitive brain-computer interface industry by 2030.

Why brain chip privacy is such a big concern
We already worry about phones listening, apps tracking location and smart TVs collecting viewing habits. Brain-computer interfaces take that concern to another level.
A BCI collects signals from the nervous system. Today, that may mean decoding movement intent, such as whether a patient wants to move a cursor left or right. But as the technology improves, the data could become more sensitive.
That raises some big questions. Who owns the brain data? Can it be sold, shared or used to train AI systems? Could an insurer, employer or government ever demand access? What happens if a company changes its privacy policy after the implant becomes part of someone’s daily life?
Those questions sound dramatic until you remember how many connected devices began as conveniences and turned into data pipelines.
A brain chip designed for medical help should not become another ad platform, another surveillance tool or another database waiting to be breached.
YOUR HEALTH DATA IS BEING SOLD WITHOUT YOUR CONSENT
Could hackers target brain-computer interfaces?
This is where the whole brain-chip conversation gets very serious. Any device that connects to a computer raises security questions. A brain-computer interface raises even bigger ones because it deals with signals from your body and, in some cases, the devices that help you move or communicate.
The concern here is someone getting access to neural data, device settings or the commands moving between the implant and outside equipment. Think about that for a second. If a brain chip helps someone control a robotic hand, a wheelchair or a communication device, a security failure could affect far more than privacy. It could affect that person’s independence and safety. That to me is scary.
Companies building these devices need to treat cybersecurity like part of the surgery, not some software update they figure out later. Encryption, strict access controls, medical-grade testing and clear update policies should be baked in from day one.
And because a brain implant may stay inside a person’s body for years, long-term support has to be part of the deal. No one should end up with an outdated implant in their head because a company moved on to the next big product launch.
What China’s brain chip means to you
For now, this technology is geared toward patients with serious medical needs. So, no, most of us are not lining up for a brain chip anytime soon. But this should still get your attention.
We already give up a lot of personal data through our phones, watches, cars and smart home devices. A brain implant takes that to a whole different level because the data comes from inside the body. That is about as personal as it gets.
Before this technology moves beyond hospitals and medical trials, patients need plain answers before they agree to anything. They should know who can access the data, how long it gets stored, whether it can be shared and whether it can help train AI systems.
The medical potential here is incredible. Helping someone regain control or communicate again could change a life. But the privacy protections need to be just as strong as the technology itself.

Kurt’s key takeaways
China’s NEO brain chip could be a huge step forward for people living with paralysis. If this technology helps someone regain control or communicate again, that is powerful. But I also think we need to be very careful here. Once a device connects your brain signals to outside technology, the privacy stakes change fast. We are talking about data tied to your nervous system. That to me is the line we need to watch closely. Brain chips could do incredible good. But companies and governments need clear limits before this technology moves any further into everyday life. The promise is real. So are the risks. And when the data comes from inside your own head, “trust us” will never be enough.

NASA selects Eric Schmidt’s rocket company for a 2028 mission to Mars
Relativity Space, the rocket company led by former Google executive Eric Schmidt, was picked to launch NASA’s Aeolus payload to Mars in 2028, as reported earlier by TechCrunch. Under a new public-private partnership, Relativity Space will provide the “spacecraft, rocket, and cruise operations” to fly Aeolus to Mars, where the payload will “provide the first integrated, daily, global view of Martian winds, temperatures, dust, and clouds.”
The Aeolus payload will have four instruments on board for studying the Martian atmosphere, which NASA says will “directly inform entry, descent, and landing systems and support safer, more predictable mission planning for astronauts.”
Schmidt, who served as CEO of Google from 2001 to 2011, became Relativity Space’s CEO in 2025, a couple of years after it launched the “world’s first 3D-printed rocket,” Terran 1, which failed shortly after launch. Relativity Space’s larger Terran R rocket isn’t scheduled to have its first launch until later this year.
