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.

Lucid and Uber team with Nuro for new robotaxi program with Gravity SUV
The plan currently is to launch it to the public in the Bay later this year.
Lucid and Uber are teaming up with Nuro to launch an autonomous robotaxi program utilizing the automaker’s Gravity SUV. The project will be unveiled at CES 2026, introducing an in-cabin rider experience completely designed by Uber, the world’s largest ride-sharing service.
Back in 2025, the partnership between the three companies was announced, aiming to launch a unique ride-sharing platform using over 20,000 Lucid vehicles equipped with the Nuro Driver technology. The vehicles are owned and operated by Uber.
The companies have already initiated some testing in the San Francisco Bay Area, which is a big step in the right direction for the project. The plan currently is to launch it to the public in the Bay later this year. Nuro will lead the testing using robotaxi engineering prototypes that are supervised by autonomous vehicle operators.
Currently, there are over 100 robotaxis in the Engineering Test Fleet.
The Gravity vehicles are fitted with a next-gen sensor array featuring high-res cameras, solid-state LiDAR sensors, and radars that will provide a 360-perception model, as well as a “purpose-built roof-mounted halo designed to maximize sensor visibility,” which is seen on top of the Gravity unit above.
The halo also has integrated LEDs to help riders more easily identify the correct vehicle by displaying their initials. The halo will also provide clear status updates from pickup through dropoff.
These units for the robotaxi program between the three companies will start being produced later this year at Lucid’s Arizona AMP-1 factory.
Uber chose the Lucid Gravity specifically due to its “unprecedented comfort” and its reputation, as it was named to Car and Driver’s 10 Best for 2026. But Uber is customizing some things for the Gravity so that it is specifically catered to robotaxi riders:
- For the first time, Uber is designing the in-vehicle rider experience, which will include interactive screens with entertainment and climate control options, as well as support contacts and vehicle maneuver requests, like a request to pull over.
- It will also have in-vehicle visualization, showing what the robotaxi sees and its path in real-time. This will be a nice transition for those who are skeptical about driverless vehicles, and will show what the vehicle and its sensors, LiDAR, and cameras see.
- The Gravity is also a sizeable SUV, which will give riders space for themselves and their luggage.
This is the latest application of a ride-hailing platform that leans on autonomy for its operation, essentially phasing out the need for human drivers in various markets, starting with the Bay Area.
More companies are dipping their toes in the project, giving them the opportunity to establish some early momentum, as there are only a handful of companies that are currently operating this in the United States. Uber, Lucid, and Nuro aim to be the next, and initiating this program at this time is big for their chance at success.

Tesla Cybercab test fleet expands in Austin and Bay Area
In total, the Robotaxi fleet is comprised of 139 total vehicles in both Austin and the Bay Area. The vast majority of these units are Model Y cars, but the Cybercab is the most recent addition to the fleet.
Tesla has expanded its fleet of Cybercab test units in both Austin and the Bay Area of California, as the vehicle is heading toward the first production stages, hopefully early this year.
As the first few units were spotted in Austin late last year, Tesla is now operating seven total Cybercab units in testing, three of which were spotted over the weekend in Texas. Bay Area testing just started on January 3, with both units also being added to the fleet on Saturday and Sunday.
In total, there are seven Cybercabs now operating, according to Robotaxi Tracker, each with different license plates that have been observed over the course of the last several weeks; the first unit was spotted in Austin on December 18.
The future should look like the future, indeed.
The Cybercab really changes the look of the roads, but without the shock factor of the Cybertruck. It’s a pretty good balance, imo.pic.twitter.com/PM0KbjzhxR

The expansion of the Cybercab test fleet is a slow but steady process that Tesla is taking to get the car on public roads ahead of its initial production stages.
CEO Elon Musk said last week that Tesla has already started some test production phases of the vehicle at Gigafactory Texas, which is located outside of Austin.

However, it will likely be some time before Tesla actually adds it to the fleet for rides that are available to the public. Tesla plans to build it without a steering wheel or pedals, so the company will have to reach Level 5 autonomy at that point before customers can hail rides and take it to their destination.
In total, the Robotaxi fleet is comprised of 139 total vehicles in both Austin and the Bay Area. The vast majority of these units are Model Y cars, but the Cybercab is the most recent addition to the fleet.

Tesla Germany’s “Giga Train’s” improved service gets rave reviews
As per recent reports, Tesla’s free “train”Giga Train” service will increase its daily trips to six starting this week.
Tesla has expanded its employee shuttle service from Berlin Ostbahnhof East Station to the Gigafactory Berlin-Brandenburg. As per recent reports, Tesla’s free “train”Giga Train” service has increased its daily trips to six starting this week.
The service has so far received positive reviews from the facility’s employees, some of whom noted that the upgraded shuttle train has reduced their travel time by a notable margin.
Giga Berlin’s expanded shuttle service
As noted in a rbb24 report, Giga Berlin’s free shuttle train now operates six times daily, up from one previously. The service also goes directly to the Model Y production facility without stopping at other stations. Tesla employee Dené Schunck described the service to rbb24 in a comment: “The shuttle goes directly to the factory site, without any transfers, which reduces the commute time for our employees by almost half,” Schunck stated.
Operated by Ostdeutsche Eisenbahngesellschaft (Odeg) after switching from Niederbarnimer Eisenbahn (NEB), Giga Berlin’s shuttle train, which also stops at Ostkreuz and Erkner, remains free for all riders, including non-Tesla employees. It has been fully funded by Tesla Germany since September 2023.
Employees praised the changes: One Giga Berlin worker stated that it “definitely makes the journey easier” because employees “used to need two hours for the round trip from Berlin, but now it’s significantly faster.”
Tesla Germany’s previous comments
In late 2025, reports emerged stating that Tesla Germany will be expanding its shuttle train service by adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg. In a comment, Tesla Germany stated that the updated service would mirror the shift changes for the Model Y factory’s employees.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany noted.
At the time, Tesla Germany also stated that despite construction being done at Fangschleuse and Köpenick stations, the route of the Giga Train has been optimized to maintain a predictable 35-minute travel time. This should provide Tesla Germany’s employees with a convenient way to travel to and from Giga Berlin.
