Neurotechnology to treat spinal cord injury sees early success in human spine implant
A spinal implant device developed by scientists and doctors in Switzerland has enabled three paralyzed men to walk again. The men, aged 30, 35, and 48, participated in a trial conducted by research institute École Polytechnique Fédérale de Lausanne (EPFL) wherein the device was first surgically implanted in the cervical (neck) part of their spines followed by rehabilitative therapy. Within one week, all of the men were able to regain motion in their lower limbs, and after three months, they were able to walk hands-free with hip support in a gravity-assist mechanism.
Spinal cord injury interferes with the cell communication essential in the nervous system for enabling neurological functions. When a human or animal wants to move a limb, the brain sends electrical signals down the spinal cord which trigger, or “innervate”, nerve cells connected to muscles to move as instructed. In the case of severe or complete paralysis, as was the case with the three men treated, the signals from the brain are too weak to reach the areas that are paralyzed. The implant used in the trial provided a targeted boost to the signals used for lower limb movement.
The device, an “implantable pulse generator” which delivers epidural electrical stimulation (EES) to the spinal cord, is commonly used for deep brain stimulation but was modified to enable wireless commands to meet the trial’s needs. To achieve the necessary types of impulses to the spine, researchers studied the bodies’ electrical activity behavior when motion was attempted by participants. That information was used to develop algorithms which would control electrical pulses sent from the device.
As detailed in the research paper reporting the experiments and results for the implant, different types of muscle movements involve different groups of nerve cells being activated. The three men who participated in the trial were able choose the types of motion they wanted to attempt, i.e., standing or walking, via a tablet with a mobile app. The app would then communicate with the implant to direct the types of pulses sent to match the signals for the nerve cell groups associated with the movement desired.
Surprisingly for researchers, the trial also resulted in limited repair of the previously damaged spinal cord nerve connections responsible for participants’ paralysis. One of the participants was even able to walk a few paces without the device’s signals after a few months of therapy. Additionally, the animal portion of the trial showed nerve fibers growing back and connecting to the brain again.
There are many positive potential treatment developments indicated by the success of this trial, but certain limitations should be noted. First, the electrical pulses cause discomfort for participants and thus can’t be maintained for long periods of time. This initial trial was only able to enable walking for approximately one hour. Second, the treatment carries a high price tag. The cost of the device and therapy together puts the paralysis treatment out of reach for many of its would-be beneficiaries. As more research continues along with expended trials planned to take place in the next three years, it’s possible for it to be available on a wide scale.

Tariff reprieve might be ‘Tesla-friendly,’ but it’s also an encouragement to others
Tesla stands to benefit from the tariff reprieve, but it has some work cut out for it as well.

After Secretary of Commerce Howard Lutnick made adjustments to the automotive tariff program that was initially announced, many quickly pointed to the reprieve as “Tesla-friendly.”
While that may be the case right now, it was also a nudge of encouragement to other companies, Tesla included, to source parts from the U.S. in an effort to strengthen domestic manufacturing. Many companies are close, and it will only take a handful of improvements to save themselves from tariffs on their cars as well.
Yesterday, Sec. Lutnick confirmed that cars manufactured with at least 85 percent of domestic content will face zero tariffs. Additionally, U.S. automakers would receive credit up to 15 percent of the value of vehicles to offset the cost of imported parts.
Big Tesla win? Sec Lutnick says cars with 85% domestic content will face zero tariffs
“This is ‘finish your cars in America and you win’,” Lutnick said.
Many were quick to point out that only three vehicles currently qualify for this zero-tariff threshold: all three are Teslas.
However, according to Kelley Blue Book’s most recent study that revealed who makes the most American cars, there are a lot of vehicles that are extremely close to also qualifying for these tariff reductions.
Tesla has three vehicles that are within five percent, while Ford, Honda, Jeep, Chevrolet, GMC, and Volkswagen have many within just ten percent of the threshold.

It is within reach for many.
Right now, it is easy to see why some people might think this is a benefit for Tesla and Tesla only.
But it’s not, because Tesla has its Cybertruck, Model S, and Model X just a few percentage points outside of that 85 percent cutoff. They, too, will feel the effects of the broader strategy that the Trump administration is using to prioritize domestic manufacturing and employment. More building in America means more jobs for Americans.

However, other companies that are very close to the 85 percent cutoff are only a few components away from also saving themselves the hassle of the tariffs.
Ford has the following vehicles within just five percent of the 85 percent threshold:
- Ford Mustang GT automatic (80%)
- Ford Mustang GT 5.0 (80%)
- Ford Mustang GT Coupe Premium (80%)
Honda has several within ten percent:
- Honda Passport All-Wheel-Drive (76.5%)
- Honda Passport Trailsport (76.5)
Jeep has two cars:
- Jeep Wrangler Rubicon (76%)
- Jeep Wrangler Sahara (76%)
Volkswagen has one with the ID.4 AWD 82-kWh (75.5%). GMC has two at 75.5% with the Canyon AT4 Crew Cab 4WD and the Canyon Denali Crew Cab 4WD.
Chevrolet has several:
- Chevrolet Colorado 2.7-liter (75.5%)
- Chevrolet Colorado LT Crew Cab 2WD 2.7-liter (75.5%)
- Chevrolet Colorado Z71 Crew Cab 4WD 2.7-liter (75.5%)
These companies are close to reaching the 85% threshold, but adjustments need to be made to work toward that number.
Anything from seats to fabric to glass can be swapped out for American-made products, making these cars more domestically sourced and thus qualifying them for the zero-tariff boundary.
Frank DuBois of American University said that manufacturers like to see stability in their relationships with suppliers and major trade partners. He said that Trump’s tariff plan could cause “a period of real instability,” but it will only be temporary.
Now is the time to push American manufacturing forward, solidifying a future with more U.S.-made vehicles and creating more domestic jobs. Tesla will also need to scramble to make adjustments to its vehicles that are below 85%.

Tesla Cybertruck RWD production in full swing at Giga Texas
Videos of several freshly produced Cybertruck LR RWD units were shared on social media platform X.

It appears that Tesla is indeed ramping the production of the Cybertruck Long Range Rear Wheel Drive (LR RWD), the most affordable variant of the brutalist all-electric pickup truck.
Videos of several freshly produced Cybertruck LR RWD units were shared on social media platform X.
Giga Texas Footage
As per longtime Tesla watcher Joe Tegtmeyer, Giga, Texas, was a hotbed of activity when he conducted his recent drone flyover. Apart from what seemed to be Cybercab castings being gathered in the complex, a good number of Cybertruck LR RWD units could also be seen in the facility’s staging area. The Cybertruck LR RWD units are quite easy to spot since they are not equipped with the motorized tonneau cover that is standard on the Cybertruck AWD and Cyberbeast.
The presence of the Cybertruck LR RWD units in Giga Texas’ staging area suggests that Tesla is ramping the production of the base all-electric pickup truck. This bodes well for the vehicle, which is still premium priced despite missing a good number of features that are standard in the Cybertruck AWD and Cyberbeast.
Cybertruck Long Range RWD Specs
The Cybertruck LR RWD is priced at $69,990 before incentives, making it $10,000 more affordable than the Cybertruck AWD. For its price, the Cybertruck Long Range RWD offers a range of 350 miles per charge if equipped with its 18” standard Wheels. It can also add up to 147 miles of range in 15 minutes using a Tesla Supercharger.
Much of the cost-cutting measures taken by Tesla are evident in the cabin of the Cybertruck LR RWD. This could be seen in its textile seats, standard console, seven-speaker audio system with no active noise cancellation, and lack of a 9.4” second-row display. It is also missing the motorized tonneau cover, the 2x 120V and 1x 240V power outlets on the bed, and the 2x 120V power outlets in the cabin. It is also equipped with an adaptive coil spring suspension instead of the adaptive air suspension in the Cybertruck AWD and Cyberbeast.

Tesla preps for a Cybercab takeover of the Robotaxi platform after pilot program
Tesla looks to be preparing the Cybercab for Robotaxi operation as castings pile up at Gigafactory Texas.

Tesla is evidently preparing for the Cybercab to take over the Robotaxi platform after the pilot program in Austin, Texas, is launched.
That claim is made based on new drone footage from Gigafactory Texas captured by Joe Tegtmeyer, who found hundreds of Cybercab castings that have accumulated on property in Austin.

The Cybercab is Tesla’s dedicated Robotaxi vehicle that was unveiled last October. It features just two seats and is minimalistic, aimed toward allowing the Full Self-Driving suite to chauffeur passengers from Point A to Point B without ever having to deal with human interaction or any responsibilities within the vehicle.
In June, Tesla plans to launch its first Robotaxi rides in Texas. Although employees in Austin and in the Bay Area of San Francisco have already had access to over 1,500 trips and 15,000 miles of autonomous (but supervised) travel, Tesla plans to launch a driverless version in a limited fashion in June.
However, this initial pilot program, while presumably operating on an Unsupervised version of the FSD, will only utilize Model Ys, at least at first.
The drone footage captured by Tegtmeyer today seems to tell a story of a quick transition to the Cybercab for the Robotaxi responsibilities, especially as Tesla gets its feet wet with the early Unsupervised FSD rides and gains confidence in the fleet’s ability to navigate passengers:
Many more @Tesla Cybercab Castings at Giga Texas today! Looks like around 75 or so in the racks waiting for production line testing (or more than that?) 😎 pic.twitter.com/0zUdH6BKLx
— Joe Tegtmeyer 🚀 🤠🛸😎 (@JoeTegtmeyer) April 30, 2025
It appears that between 400 and 500 Cybercab castings can be seen in the images Joe captured, a very respectable number considering the company said it will not launch the Robotaxi with the initial rides it gives in Austin.
The images seem to paint a picture that Tesla is truly ready to get things moving in terms of the Cybercab project. While it does not plan to use the vehicle initially, its manufacturing efforts for the car are being prepared by stacking these castings so they’re ready to be expanded upon into the real thing.
On the most recent Earnings Call, Tesla’s VP of Vehicle Engineering, Lars Moravy, said the Cybercab’s engineering has progressed over the last several months to “derisk things like corrosion, the ceiling across the seams of the vehicle, and when you marry several components,” and even things like early crash testing have already taken place.
Moravy continued, “As with all that combined, we kind of go into the builds that we have in this quarter for the Cybercab product, and that’s the next real big test of full-scale integration with the unboxed process. And that’s kind of where we are. So you’ll see them on the test roads in a couple of months.”
