Paralyzed individuals successfully use brain waves to operate tablet computers

Published

on

In a collaborative study presented by scientists primarily affiliated with Stanford and Brown Universities, participants suffering from significant paralysis were successfully able to use non-modified applications on an Android tablet using their brain waves. In previous studies, “point-and-click” computer functionality interpreted from these kinds of signals has been accomplished, but the applications available to participants was limited to software and devices that had been specialized and personalized for users’ specific needs. This study has demonstrated technology that overcomes this limitation and enables access to the full range of software available to non-disabled users. Participants enjoyed applications previously unavailable to them such as streaming music services and a piano keyboard player.

To accomplish the study’s objectives, scientists capitalized and combined existing technologies for their unique end. Brain waves from participants’ brain implants were sent to a commercially available recording system and then processed and decoded by an existing real-time interpreter software. The decoded data was then transmitted to a Bluetooth interface configured as a wireless mouse which was paired to an Android tablet. While the steps to accomplish the task at hand are many, the result somewhat resembles telepathy but largely resembles greater accessibility for the disabled.

Individuals suffering from various forms of paralysis generally have difficulty using communication technologies. Strokes, neurological injuries, and neurodegenerative diseases such as ALS (Amyotrophic Lateral Sclerosis) can all lead to limited physical functionality that impairs the use of communication devices. However, although physical mobility is affected by paralytic conditions, the brain often continues to send signals to muscles to trigger movement. Using this attempted signaling, scientists have been developing technology to bridge the disconnect between the brain’s signals and the intended outcomes.

Brain-computer interfaces (BCIs) record activity in the brain and interpret that data to generate an action. Using microelectrode arrays implanted into areas of the brain corresponding to desired functionality, neural signals are transmitted to the array’s plates or shanks that interpret their activity into usable data. All of the participants in this study had implants placed in the hand area of their brains’ dominant motor cortexes from which signals were recorded. Since computers inherently operate via digital signals, they stand as promising tools to facilitate communications originating from BCIs. In particular, algorithms developed using machine learning have been designed to interpret brain signals into computer mouse movement, a capability which can be expanded into software accessibility.

One of the study’s researchers, Krishna V. Shenoy, is a consultant for Neuralink Inc., Elon Musk’s brain-computer interface company. While BCIs in general have similar goals to Neuralink’s, the major difference is in purpose, namely in that Musk’s company aims to enhance human capabilities to better compete with artificial intelligence rather than restoring or improving lost abilities. Where BCIs interpret existing brain signals to reenable preexisting capabilities, Neuralink hopes to merge computing and brain power into a seemingly singular function via tiny, dust-sized particles rather than traditional implants.

Tesla Cybercab launch is imminent after latest sighting at Giga Texas

Tesla just gave what is perhaps its biggest signal yet that the launch of the Cybercab, its autonomous ride-hailing-geared car, is imminent.

The Cybercab has been spotted outside of Gigafactory Texas in massive numbers over the past few days, with hundreds of units being stored on property just days after the vehicle received a Certificate of Conformity from the EPA.

Today, things were a bit different.

Cybercabs spotted on Giga Texas property today had an addition: a Cybercab decal on the side, reminiscent of the “Robotaxi” ones that were placed on Model Ys just as the company launched its ride-sharing platform about a year ago.

Tesla could be signaling that the Cybercab is preparing to enter the Robotaxi fleet in the coming weeks or months with this move. It seems more symbolic than anything; Tesla is ready to throw Cybercabs in the ride-hailing platform just as it did with Model Ys last year.

The addition of the Certificate of Conformity awarded to the Cybercab is another major factor working to Tesla’s advantage. The company now has permission from the EPA to allow the vehicle to operate on public roads and enter the chain of commerce. It’s officially street legal.

The big question that remains is whether Tesla will be able to operate the car without a safety monitor, especially considering it plans to put the car out there without a steering wheel or pedals. With the Cybercab only having a seating capacity of two, it is hard to believe Tesla will even consider putting a Safety Monitor in the car.

It did recently self-certify as Level 4 and has the ability to operate driverless vehicles in the State of Texas under a law that took effect on May 28. You can read more about that here:

We’d imagine Cybercabs will be on the roads as soon as July, but August will likely be a better estimate of when the car will be entered into the Cybercab fleet. It all depends at where Tesla is, as they’ve truly prioritized safety with the rollout of the Robotaxi platform.

Elon Musk says this part of Tesla ‘makes no sense’

Elon Musk has publicly questioned Moody’s credit assessments following the rating agency’s decision to assign SpaceX a Baa1 investment-grade rating, two notches above Tesla’s Baa3. The comments came amid discussions comparing the two companies’ financial profiles.

SpaceX earned its first-time Baa1 rating with a stable outlook from Moody’s. The agency highlighted the company’s leadership in orbital launches, the growing recurring revenue from its Starlink satellite network, strong vertical integration, U.S. government contracts, and emerging opportunities in AI infrastructure.

These factors were cited as supporting robust cash flows, margin expansion, and financial flexibility.

Musk responded directly: “Tesla’s credit rating is ridiculously low tbh,” and added, “Yeah, makes no sense. Tesla has over $40B in cash, no debt, and is consistently profitable!” His remarks underscored Tesla’s balance sheet strength and profitability at a time when many traditional automakers continue to report losses in the shift to electric vehicles.

Tesla maintains a leading position in the global EV market, with diversification into energy and storage, battery technology, and robotics through projects like Optimus. Recent financial updates show the company generated positive free cash flow of $1.4 billion in Q1 2026, supported by operating cash flow of $3.9 billion. Cash and short-term investments stood at approximately $44.7 billion.

Moody’s has affirmed Tesla’s Baa3 issuer rating with a stable outlook in periodic reviews, acknowledging the company’s EV leadership, technology strengths, including AI for autonomous vehicles, solid profitability, and strong liquidity.

However, the agency has also noted challenges in the automotive segment and expectations for margin pressures.

Musk’s critique highlights a common debate about how traditional rating methodologies apply to high-growth, capital-intensive technology companies. SpaceX benefits from long-term government-backed contracts and diversified, recurring revenue streams, while Tesla’s valuation reflects heavy investment in future technologies such as autonomy and robotics.

Both ratings remain investment-grade, yet the one-notch difference has fueled online discussion about potential inconsistencies in evaluating innovative firms.

The exchange comes as SpaceX explores financing options following its recent valuation milestones, while Tesla continues executing on its multi-year roadmap. Musk’s pointed response serves as a reminder that credit ratings, though influential for borrowing costs, represent one lens through which markets assess corporate strength—and that company leaders often view their financial positions through the lens of long-term innovation and cash generation rather than short-term risk metrics alone.

Tesla Full Self-Driving faces major pushback in Europe

Published

A new report from Reuters claims that a transport authority in Sweden is pushing back against the approval of Tesla’s Full Self-Driving suite because it will travel over speed limits.

The report says the Swedish Transport Administration (TRV) recommends the European Union votes against FSD’s approval. TRV believes it should not be approved until Tesla disables FSD’s ability to speed.

TRV sent a letter to the European Union’s Technical Committee on Motor Vehicles (TCMV), which is set to meet on June 30 to discuss the potential approval of the Tesla FSD suite in the country. Tesla, which has received various approvals in Europe over the past two months, has not provided a comment.

Teslas operating on FSD do travel over the speed limit, depending on the Speed Profile that is chosen. Drivers have the ability to disengage FSD at any point; Tesla specifically states that those supervising the suite are responsible for its actions.

Let’s cut to the chase: humans operating any vehicle speed almost daily in the United States. Realistically, speed limits in the U.S. are more frequently treated as speed minimums. However, other countries are different, and driving behaviors are less aggressive.

TRV believes that “allowing automated systems to systematically exceed legal speed limits…risks undermining both the legal framework and the expected safety benefits of ​vehicle automation,” the report stated. It’s surprising that Tesla has not received this claim from other countries previously.

This could be a good argument to bring Max Speed back, the setting that previously allowed the driver to choose the absolute fastest the car would travel.

This would still put the responsibility of supervision in the hands of the driver. It would allow the driver to choose whether the car would travel over the speed limit or not, acknowledging that they set the speed, and if they get pulled over, there would be no ability to argue it.

However, it does not seem as if this is something Tesla will do, especially considering many U.S. drivers have requested the feature in an effort to eliminate speeding or at least tone it down. The company has not shown any interest in bringing it back.

Tesla has approvals for FSD in Europe in Estonia, Lithuania, Denmark, the Netherlands, and Belgium.
