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.

Tesla lands new partnership with Uber as Semi takes center stage

Tesla and Uber will work together, using the company’s all-electric Semi, to make sustainable Class 8 electric trucks more affordable with three main strategies: Subsidized Pricing, Predictable Growth, and Optimization of Utilization.

The Tesla Semi has led to a new partnership between the company and Uber, as the two are launching a program that aims to revolutionize logistics by making sustainable commercial vehicles more accessible.

Uber announced on Tuesday that it was planning to launch the Dedicated EV Fleet Accelerator Program in a new partnership with Tesla. Uber’s Freight division is mainly responsible for the new program, which it calls a “first-of-its-kind buyer’s program designed to make electric freight more affordable and accessible by addressing key adoption barriers.”

Subsidized Price: Fleets purchasing Tesla Semis through this program will receive a subsidy on the purchase price.

Predictable Growth: Fleets will integrate their Tesla Semis into Uber Freight’s dedicated solutions for shippers for a pre-determined period. This creates an opportunity for carriers to forecast revenue with confidence, while shippers gain consistent access to reliable, zero-emission capacity.
Optimize Utilization: Uber Freight taps into its extensive freight network to match carriers with consistent, high-quality freight from our strong shipper base—helping ensure the addition of these Tesla Semis stay fully utilized and carriers see dedicated, real, measurable returns from the start

Tesla will work directly with interested companies to iron out technical details about the Semi, as well as its cost of ownership based on the tailored needs of their business. Fleets can expect savings on the first day, Uber says, as they will avoid diesel fuel costs and reduced maintenance, a widely known advantage of EVs.

Uber announced that it had partnered with select carriers to pilot the Dedicated EV Fleet Accelerator Program prior to its launch:

“During the 2-month pilot program, the Tesla Semis showcased both reliability and efficiency for Uber Freight’s shipper network. Over 394 hours of drive time, carriers covered 12,377 miles. With an average net energy consumption of just 1.72 kWh per mile and only 60 hours of total charge time, these results highlight the operational viability of Tesla Semis on demanding freight lanes. “

In its press release launching the program, Uber effectively highlights how the use of the Semi can impact a company’s margins and profitability through fuel savings, reduced maintenance costs, and lower total cost of ownership.

This is something that turns so many people away from gas cars and toward EVs, so it’s no surprise that Uber wanted to emphasize this point on a larger scale with a company that utilizes a fleet of vehicles.

Tesla has been experimenting with a select group of companies, as well. It partnered with PepsiCo. several years ago, in an effort to launch a pilot program for the Semi. It had excellent results, showing higher efficiency, lower costs, and an exceptional ability to handle long runs.

Drivers have had a lot of positive things to say:

The Semi will enter mass production next year, but we anticipate that some companies will commit to Uber’s new platform well before then.

Tesla will recall Powerwall 2 units in Australia after a handful of property owners reported fires that caused “minor property damage.” The fires were attributed to cells used by Tesla in the Powerwall 2.

Tesla Powerwall is a battery storage unit that retains energy from solar panels and is used by homeowners and businesses to maintain power in the event of an outage. It also helps alleviate the need to rely on the grid, which can help stabilize power locally.

Powerwall owners can also enroll in the Virtual Power Plant (VPP) program, which allows them to sell energy back to the grid, helping to reduce energy bills. Tesla revealed last year that over 100,000 Powerwalls were participating in the program.

The Australia Competition and Consumer Commission said in a filing that it received several reports from owners of fires that led to minor damage. The Australian government agency did not disclose the number of units impacted by the recall.

The issue is related to the cells, which Tesla sources from a third-party company.

Anyone whose Powerwall 2 unit is impacted by the recall will be notified through the Tesla app, the company said.

Tesla is launching Cybertruck orders in a new market, but there’s a bit of a catch.

The Cybertruck was launched in the Middle East earlier this year, as Tesla launched the ability to place a reservation for the all-electric pickup in the United Arab Emirates. It would be the first market outside of North America that would have the ability to place an order for the Cybertruck.

Other markets where the vehicle has been widely requested, like Europe and Asia, have still not approved the vehicle to be sold to the public, mostly because of size and design restrictions.

However, in the UAE, Tesla is opening up the ability for those who placed reservations for the vehicle to finally put in their order. The Order Configurator is only available to those who have already placed a reservation; it is not yet available to the public.

Tesla said it would open up the public online configurator across the Middle East in the coming weeks:

The UAE is not the only country that will have access to the Cybertruck, as fans in other Middle Eastern countries will also be able to place orders soon. Tesla announced back in April that Saudi Arabia and Qatar would also have Cybertruck deliveries.

These vehicles will be built at Tesla’s Gigafactory Texas plant just outside of Austin, as Gigafactory Berlin and Gigafactory Shanghai, two factories located in the same hemisphere as the Middle East, do not have established lines for Cybertruck production.

As for the other markets, Tesla CEO Elon Musk has hinted that the company could develop a smaller Cybertruck for those markets, as he admitted that in the long term, it likely made sense to build a more compact version for regions where roads are traditionally tighter.
