Bio-tech firm develops 3D printed replacement cornea for human eyes

Published

on

After successfully transplanting the first 3D-printed cornea in an animal, North Carolina company Precise Bio has recently announced the launch of a dedicated business for creating marketable, 3D-printed products for human eyes. Founded by scientists from the Wake Forest Institute of Regenerative Medicine, this company is developing bio-fabrication printers that can restore cells, tissues, and organs. Their proprietary technology, a 4D bio-printing platform, is said to resolve existing limitations presented by other bioprinters to enable more complex tissues to be engineered for transplants and treatments. By focusing on developing marketable products for the eye, the company aims to achieve rapid advancement in its field and move to overhaul the whole organ transplant system.

When a cornea is damaged by disease or injury, a replacement is often needed to restore vision. Transplant surgery using donated corneas is an available solution, however, it relies on a deceased donor. While the waiting list in the United States is nearly non-existent, other countries require longer wait times, some over a year, before one is available. The Eye Bank Association of America estimates that around 10 million people suffer from corneal blindness that could potentially be restored via transplant surgery. An artificially manufactured cornea would overcome supply limitations while also contributing to the knowledge base to develop more complex organs such as hearts and livers.

The cornea is the transparent layer covering the front part of the eye that, along with the lens, accounts for about two-thirds of the eye’s optical power. It does not contain blood vessels, making it a prime candidate for bioprinting, the field of 3D printing involving biological materials. Bioprinters differ from traditional 3D printers in ways that might not be surprising given their name. Instead of heated filament applied in layers on a plate to build an object, layers of cells and biocompatible materials are printed to form tissue. Along with a lack of blood vessels, the layered structure of the cornea also makes it well suited for bioprinting.

Precise Bio refers to its printing technique used for the corneas and other biomaterials as “4D” over the usual “3D” label due to the curing stage for the printed cells. The fourth dimension referred to is time needed, 10-14 days specifically, for the bio-printed cells and fibers to connect themselves together for biological operation in a bioreactor that keeps them warm for the duration. Aryeh Batt, Precise Bio’s CEO, summarized this step in an interview with IEEE Spectrum: “Essentially, the biology does the work, but you have to put them in the correct environment to make it happen.”

Initial animal safety studies for the corneal transplant have already been completed, and now the company must clear some additional hurdles to begin human testing. One of the major proofs for Precise Bio will be the demonstration of normal behavior of the bio-printed products. For example, during production using the 3D/4D printer, the printed cells grow rapidly into the form needed in a way that does not occur in a normal eye. The company will have to demonstrate in clinical studies how this process is controlled and stopped before transplant.

The field of 3D bioprinting is a research area receiving a significant amount of attention due to its potential for developments in tissue engineering, drug delivery, and cancer studies. In fact, hundreds of scientific articles were published on the topic this year alone. As with most new technology, however, the challenge of moving a development out of the laboratory and into the consumer marketplace is significant, but Precise Bio hopes to meet it head on with its new dedicated business.

I figured out how to charge my Tesla at my rented townhouse – Here’s how

I hope that this article is able to help the prospective EV buyer or the current Tesla owner who is living in a rental and does not have a straightforward solution to home charging. My situation will be presented in this article, and I will tell you why I went with the solution I went with, and alternatives, because there is more than one way to do this.

When I bought my Tesla Model Y Premium All-Wheel-Drive last year, I knew I would have to try to figure out a way not become totally reliant on Superchargers. After about six months of ownership, it came time to resolve that problem once and for good, and being a tenant in a rented townhouse community definitely added to my challenge.

Before I even bought my Tesla, I emailed my leasing office to see if the community had any plans to bring EV charging to the neighborhood. I had made myself available to them as I am familiar with a lot of the solutions out there and how much of an advantage this could be for the community, and attracting new tenants. After months of trying, I bought my Tesla in August anyway, and figured I’d be able to find an answer — whether positive or negative — and go from there.

I hope that this article is able to help the prospective EV buyer or the current Tesla owner who is living in a rental and does not have a straightforward solution to home charging. My situation will be presented in this article, and I will tell you why I went with the solution I went with, and alternatives, because there is more than one way to do this.

My Challenge with Home Charging

In a rental community, apartment complex, or even townhouse row, parking spots are a little complicated. I have assigned parking at my house, and unfortunately, my parking spot is not right in front of my front door. Instead, it is staggered, so my car is parked in front of my neighbor’s front door.

Initially, I had spoken to my neighbor whose spot is right in front of my front door and had gotten permission to park in their spot during the day while it is vacant. However, I was not going to be able to upgrade my outlet from a 110v-120v to the typical and suggested 220v-240v alternative.

I knew that this would mean I would need to be in my permanent spot because charging sufficiently, especially in preparation for trips or errands, would require overnight charging.

The Tesla Mobile Connector is 20 feet long, which is sufficient for most applications. Mine, however, required about 30 feet, maybe even a little more, to charge.

My Options

I had a few options: Use the Mobile Connector and park in my neighbor’s spot and charge when I could, buy an 8 or 10-gauge extension cord that could handle moving power from the Mobile Connector to my car, or buy an NACS to NACS extension cord.

I didn’t really want to do the first option, considering I knew that spot would only be available when my neighbor was not there. It didn’t seem like a viable option, and I figured it would be better to figure out something from my personal, permanent parking spot anyway.

The 10-gauge extension cord option was what I first considered: it was less expensive than buying an NACS extension, it was more readily available, and it was the first thing my friends who are electricians recommended.

However, running this option would have put the Mobile Connector in the grass or on the ground, and I was not interested in doing that. Running the risk of having that $300 connector that came with the car in the grass and exposing it to dew, dogs, and various other things just did not seem like the best idea.

I looked around for some NACS to NACS connectors, and there are a lot of options. Given that this was something that was going to plug into a $50,000 car, I chose to spend the additional money on one that was not from Amazon, and I went with this one from A2Z, which was recommended by other owners, and their reputation seemed more than positive. I was leaning toward this option anyway because it would keep the Mobile Connector off the ground, and it gave me an additional 16 feet of length to work with.

This was the solution.

Putting It Into Action

It was a relatively simple process: Plug the Mobile Connector into my house, plug the NACS to NACS extension into the Mobile Connector, plug the NACS extension into the car. It all worked immediately, but there are some things you should know if you are also planning to do this.

The first is that you should be very aware that these cables are going to be a target of thieves. I don’t have too much of an issue with this in my area, but if you’re in a place where copper wiring is heavily sought after, be sure to keep these in a place where they won’t be stolen. I put mine away when they’re not charging, and at night, they’re visible from my Ring camera, so I’m not overly concerned. Definitely be aware of it, though.

Additionally, if you’re going to run it across the sidewalk like I am, you’re going to want to pick up some sort of cable cover from a local hardware store. I picked up this one from Amazon because it was a little more heavy-duty, and it was big enough to cover the thicker gauge of the NACS to NACS extension:

I’ve considered picking up a second one for the visible cable, but I am undecided.

So far, I’ve been able to add some range to my car three times using this strategy, and while it is very slow, it is definitely worth it. It’s better than it sitting there stagnant.

Speed of Charging

Tesla says the Mobile Connector will provide you with between 3 and 5 miles of range per hour when plugged into a typical wall outlet. That is about what I’ve gotten with it. From 30 percent to 80 percent, be aware that it will take well over 24 hours to charge your car.

I plan to cover some additional details on this as time goes on, including any troubleshooting I might have to do, how much my electric bill goes up, and whether or not I run into any issues with my neighbors or my leasing office.

Starlink is partnering with Deutsche Telekom to roll out satellite-to-mobile connectivity across Europe, extending coverage to more than 140 million subscribers across 10 countries.

The service, planned for launch in 2028 in several Telekom markets, including Germany, will use Starlink’s next-generation V2 satellites and Mobile Satellite Service (MSS) spectrum to enable direct-to-device connectivity.

In a post on X, the official Starlink account stated that the agreement will be the first in Europe to deploy its V2 next-generation satellite-to-mobile technology using new MSS spectrum. The company added that the system is designed to deliver 5G speeds directly to compatible smartphones in remote areas.

Abdu Mudesir, Board Member for Product and Technology at Deutsche Telekom, shared his excitement for the partnership in a press release. “We provide our customers with the best mobile network. And we continue to invest heavily in expanding our infrastructure. At the same time, there are regions where expansion is especially complex due to topographical conditions or official constraints,” he said.

“We want to ensure reliable connectivity for our customers in those areas as well. That is why we are strategically complementing our network with satellite-to-mobile connectivity. For us, it is clear: connectivity creates security and trust. And we deliver. Everywhere.”

Under the partnership, compatible smartphones will automatically switch to Starlink’s satellite network when terrestrial coverage is unavailable, enabling access to data, voice, video, and messaging services.

Telekom reports 5G geographic coverage approaching 90% in Germany, with LTE exceeding 92% and voice coverage reaching up to 99%. Starlink’s satellite layer is intended to extend connectivity beyond those terrestrial limits, particularly in topographically challenging or infrastructure-constrained areas.

Stephanie Bednarek, VP of Starlink Sales, also shared her thoughts on the partnership. “We’re so pleased to bring reliable satellite-to-mobile connectivity to millions of people across 10 countries in partnership with Deutsche Telekom. This agreement will be the first-of-its-kind in Europe to launch Starlink’s V2 next-generation technology that will expand on data, voice and messaging by providing broadband directly to mobile phones,” she said.

Tesla reclaimed the top spot in Norway’s auto market in February as electric vehicles captured more than 98% of all new car registrations.

The rebound follows a sharp January slump triggered by VAT rule changes, which prompted numerous car buyers to advance their purchases into late 2025.

As per data from the Norwegian Road Traffic Information Council (OFV), 7,127 new electric vehicles were registered in February, representing a 98.01% market share. Fossil-fuel vehicles and hybrids accounted for just 2% of total new registrations.

Total new car registrations reached 7,272 units in February, hinting at a rapid recovery after January sales fell nearly 75% year-over-year following VAT adjustments.

OFV Director Geir Inge Stokke noted that similar patterns were observed after previous VAT changes in 2022, with demand temporarily weakening before normalizing, as noted in an Allt Om Elbil report. 

“We are now seeing signs that the market is returning to a more normal level of activity, which we also experienced after the VAT change in 2022. At that time, changes in demand led to a weak start to 2023. We have seen the same pattern this year,” he said. 

Amidst this trend, the Tesla Model Y made a strong comeback in the domestic market. After an unusually weak January that saw the Tesla Model Y drop to seventh place, the model returned to the top of Norway’s sales chart in February.

The Model Y recorded 1,073 registrations, giving it a 14.8% market share for the month. Tesla also became Norway’s top-selling brand with 1,210 registrations, representing a 16.6% share. Toyota followed with 941 registrations, while Volkswagen, Volvo, and Skoda rounded out the top five brands.

The February data suggests that Tesla’s January dip was tied more to timing effects around VAT adjustments than to structural demand shifts. It would then be interesting to see how the rest of the year unfolds for Tesla, particularly as the company pushes for the release of its Full Self-Driving (Supervised) system to Europe this year.
