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.

Musk bankers looking to trim xAI debt after SpaceX merger: report

xAI has built up $18 billion in debt over the past few years, with some of this being attributed to the purchase of social media platform Twitter (now X) and the creation of the AI development company. A new financing deal would help trim some of the financial burden that is currently present ahead of the plan to take SpaceX public sometime this year.

Elon Musk’s bankers are looking to trim the debt that xAI has taken on over the past few years, following the company’s merger with SpaceX, a new report from Bloomberg says.

xAI has built up $18 billion in debt over the past few years, with some of this being attributed to the purchase of social media platform Twitter (now X) and the creation of the AI development company. Bankers are trying to create some kind of financing plan that would trim “some of the heavy interest costs” that come with the debt.

The financing deal would help trim some of the financial burden that is currently present ahead of the plan to take SpaceX public sometime this year. Musk has essentially confirmed that SpaceX would be heading toward an IPO last month.

The report indicates that Morgan Stanley is expected to take the leading role in any financing plan, citing people familiar with the matter. Morgan Stanley, along with Goldman Sachs, Bank of America, and JPMorgan Chase & Co., are all expected to be in the lineup of banks leading SpaceX’s potential IPO.

Since Musk acquired X, he has also had what Bloomberg says is a “mixed track record with debt markets.” Since purchasing X a few years ago with a $12.5 billion financing package, X pays “tens of millions in interest payments every month.”

That debt is held by Bank of America, Barclays, Mitsubishi, UFJ Financial, BNP Paribas SA, Mizuho, and Société Générale SA.

X merged with xAI last March, which brought the valuation to $45 billion, including the debt.

SpaceX announced the merger with xAI earlier this month, a major move in Musk’s plan to alleviate Earth of necessary data centers and replace them with orbital options that will be lower cost:

“In the long term, space-based AI is obviously the only way to scale. To harness even a millionth of our Sun’s energy would require over a million times more energy than our civilization currently uses! The only logical solution, therefore, is to transport these resource-intensive efforts to a location with vast power and space. I mean, space is called “space” for a reason.”

The merger has many advantages, but one of the most crucial is that it positions the now-merged companies to fund broader goals, fueled by revenue from the Starlink expansion, potential IPO, and AI-driven applications that could accelerate the development of lunar bases.

Tesla pushes Full Self-Driving outright purchasing option back in one market

Tesla announced last month that it would eliminate the ability to purchase the Full Self-Driving software outright, instead opting for a subscription-only program, which will require users to pay monthly.

Tesla has pushed the opportunity to purchase the Full Self-Driving suite outright in one market: Australia.

The date remains February 14 in North America, but Tesla has pushed the date back to March 31, 2026, in Australia.

Tesla announced last month that it would eliminate the ability to purchase the Full Self-Driving software outright, instead opting for a subscription-only program, which will require users to pay monthly.

If you have already purchased the suite outright, you will not be required to subscribe once again, but once the outright purchase option is gone, drivers will be required to pay the monthly fee.

The reason for the adjustment is likely due to the short period of time the Full Self-Driving suite has been available in the country. In North America, it has been available for years.

Tesla hits major milestone with Full Self-Driving subscriptions

However, Tesla just launched it just last year in Australia.

Full Self-Driving is currently available in seven countries: the United States, Canada, China, Mexico, Australia, New Zealand, and South Korea.

The company has worked extensively for the past few years to launch the suite in Europe. It has not made it quite yet, but Tesla hopes to get it launched by the end of this year.

In North America, Tesla is only giving customers one more day to buy the suite outright before they will be committed to the subscription-based option for good.

The price is expected to go up as the capabilities improve, but there are no indications as to when Tesla will be doing that, nor what type of offering it plans to roll out for owners.

Starlink terminals smuggled into Iran amid protest crackdown: report

Roughly 6,000 units were delivered following January’s unrest.

The United States quietly moved thousands of Starlink terminals into Iran after authorities imposed internet shutdowns as part of its crackdown on protests, as per information shared by U.S. officials to The Wall Street Journal

Roughly 6,000 units were delivered following January’s unrest, marking the first known instance of Washington directly supplying the satellite systems inside the country.

Iran’s government significantly restricted online access as demonstrations spread across the country earlier this year. In response, the U.S. purchased nearly 7,000 Starlink terminals in recent months, with most acquisitions occurring in January. Officials stated that funding was reallocated from other internet access initiatives to support the satellite deployment.

President Donald Trump was aware of the effort, though it remains unclear whether he personally authorized it. The White House has not issued a comment about the matter publicly.

Possession of a Starlink terminal is illegal under Iranian law and can result in significant prison time. Despite this, the WSJ estimated that tens of thousands of residents still rely on the satellite service to bypass state controls. Authorities have reportedly conducted inspections of private homes and rooftops to locate unauthorized equipment.

Earlier this year, Trump and Elon Musk discussed maintaining Starlink access for Iranians during the unrest. Tehran has repeatedly accused Washington of encouraging dissent, though U.S. officials have mostly denied the allegations.

The decision to prioritize Starlink sparked internal debate within U.S. agencies. Some officials argued that shifting resources away from Virtual Private Networks (VPNs) could weaken broader internet access efforts. VPNs had previously played a major role in keeping Iranians connected during earlier protest waves, though VPNs are not effective when the actual internet gets cut.

According to State Department figures, about 30 million Iranians used U.S.-funded VPN services during demonstrations in 2022. During a near-total blackout in June 2025, roughly one-fifth of users were still able to access limited connectivity through VPN tools.

Critics have argued that satellite access without VPN protection may expose users to geolocation risks. After funds were redirected to acquire Starlink equipment, support reportedly lapsed for two of five VPN providers operating in Iran.

A State Department official has stated that the U.S. continues to back multiple technologies,  including VPNs alongside Starlink, to sustain people’s internet access amidst the government’s shutdowns.
