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.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade
Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.
Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.
Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.
Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error.
More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report.
Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.
Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.
Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.
“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
