Synchron pauses enrollment in its brain implant trials over a faulty cable.

Synchron pauses enrollment in its brain implant trials over a faulty cable. Synchron's second-generation Stentrode is the device in question, and some patients already carry it. WIRED reports the company is also cutting jobs, shrinking its New York base and building a San Diego team for a new device, with no restart date set. A company with a spotless six-patient safety record has stopped signing up new volunteers. The reason is a cable, and Synchron says the implant itself is fine. Synchron has voluntarily paused enrollment at trial sites in the US, Australia and Canada after finding a performance problem with the lead, the cable that carries signals from its Stentrode implant to the electronics under the skin, according to WIRED's Emily Mullin, who reported it on November 12. The pause covers the company's second-generation system, and some participants already have that device. Synchron told WIRED the issue does not involve the Stentrode itself and that no device-related safety issues have been identified. The pause is the company's own call, not an order from the FDA. WIRED reported that two of the five US trial sites it contacted confirmed they'd stopped enrolling. Synchron also said it would upgrade the hardware before recruitment restarts, and, as WIRED reported it, that means upgrading the whole Stentrode system rather than swapping out the cable alone. No restart date has been given. Start with what it doesn't say. Synchron's first-generation device came through its COMMAND early feasibility study with six patients, and all six met the 12-month primary endpoint of no device-related serious adverse events. The Stentrode goes in through the blood vessels, so there's no open-brain surgery. That record is why investors treated Synchron as the cautious option next to Neuralink, which had its own early setback in 2024 when threads in its first patient's implant pulled back from the brain. A lead failure is a different kind of problem from that one. It's an engineering and manufacturing fault in a part, not a safety event in a patient, and Synchron says it has brought lead design and manufacturing in-house. Frankly, that's the right fix and also an admission: a company that needs to build its own cables is a company that didn't fully control them before. BloombergNEF's tally covers plants proposed beside data centres in the US, UK and Europe, with more than 90% of capacity in America. If every US project ran, it would emit about 345 million tonnes of carbon dioxide equivalent a year, the analysts estimate. - AI data centres planning 181GW gas power - BloombergNEF data centre gas plant findings The trouble is timing. The trial is a step toward the larger, late-stage study Synchron needs before it can ask the FDA for marketing approval. Every month enrollment sits frozen is a month that study moves further out. And because the company is upgrading the full system, the data from patients with the current hardware may not map cleanly onto whatever it ships next. A restructuring running alongside. The pause didn't arrive alone. WIRED reported that Synchron is restructuring, including job cuts and a smaller footprint in New York, while it builds a team in San Diego to support an entirely new device. That San Diego hub isn't a surprise: Synchron announced it alongside its $200 million Series D in November 2025, with a plan to build a more advanced brain interface. What's new is the reported scale-back in New York, and the signal that the company's attention is moving toward the next-generation product while the current one gets fixed. If you're following the neurotech race as an investor or a founder, read this as a delay story, not a safety story. The second-generation system is the product now in question. A cable is a small part, and it's also the part that sits between the brain signal and everything that makes the signal useful. Synchron has also pledged lifelong support for people already implanted, per WIRED. As of Thursday, it hasn't said when new patients will be enrolled again. Join the discussion. No replies yet.

Neuralink co-founder Max Hodak says screen era is ending at TechCrunch Disrupt 2026.

Neuralink co-founder Max Hodak says screen era is ending at TechCrunch Disrupt 2026. Tl;dr. * Neuralink co-founder and Science Corp CEO Max Hodak will speak at TechCrunch Disrupt 2026 in San Francisco on his vision for screen-free, brain-computer-powered interfaces. * Hodak will outline how moving beyond phones and screens could redefine computing while first delivering major medical breakthroughs in vision, paralysis, and neurological disease. * TechCrunch Disrupt 2026 runs October 13-15 at Moscone West, with attendees able to save up to $200 on passes if they register before September 25. The smartphone has ruled its lives for nearly two decades. If Max Hodak is right, its days are numbered. Hodak, the Neuralink co-founder now leading biotech company Science Corp, is set to take the stage at TechCrunch Disrupt 2026 to make the case that the screen era is ending - and that direct interfaces between the brain and machines are what comes next. His session is shaping up to be one of the most talked-about talks at this year's Disrupt, TechCrunch's flagship startup and tech conference bringing together founders, investors, and technologists from around the world. Why Hodak's appearance matters. Hodak is not a futurist speaking in hypotheticals. He co-founded Neuralink with Elon Musk in 2016 and helped pioneer ultra-high-bandwidth brain implants before leaving in 2021 to found Science Corp. Since then, Science Corp has emerged as one of the most serious players in the brain-computer interface race, focused less on hype and more on near-term clinical impact. His perspective carries weight because he has built in both the Silicon Valley moonshot world and the rigorous medical-device world. At Disrupt 2026, he is expected to connect those two worlds: how today's medical implants lay the groundwork for tomorrow's consumer computing paradigm. From Neuralink to Science Corp. After departing Neuralink, Hodak launched Science Corp with a mission to treat serious diseases with advanced bioengineering, including brain-computer interfaces, optogenetics, and engineered cell therapies. The company's flagship program is the Science Eye, a visual prosthesis aimed at restoring vision for patients with retinitis pigmentosa and dry age-related macular degeneration. The system combines a gene therapy in the eye with an implanted micro-LED display that stimulates the retina - essentially bypassing damaged photoreceptors. Science Corp has already moved into human clinical trials, positioning it alongside Neuralink, Synchron, and Precision Neuroscience in the race to prove that implantable BCIs are safe, scalable, and commercially viable. That track record is why TechCrunch is putting Hodak center stage: he can speak to what actually works in humans right now, not just lab demos. How screen-free computing could work. Hodak's core argument is simple but radical: screens are a bottleneck. Every digital interaction today - tapping, typing, scrolling, staring - is a low-bandwidth workaround for what its brains actually intend. Brain-computer interfaces promise to collapse that gap by reading neural intent directly and writing information back into the nervous system. On stage, Hodak is expected to outline a phased path: * First, restore lost function like sight, movement, and speech. * Then, augment normal function with silent, hands-free, eyes-free control of devices. * Ultimately, replace the phone entirely with a persistent, contextual layer that responds to thought and perception rather than touch. It is a vision that aligns with broader moves in tech toward smart glasses, AI pins, and ambient AI assistants - but Hodak argues only neural interfaces can fully free Androguider from displays. Medical breakthroughs first, consumer second. Unlike some BCI proponents who jump straight to telepathy and memory uploads, Hodak has consistently emphasized medicine first. Expect his Disrupt talk to focus heavily on patients: people with paralysis regaining digital independence, blind patients seeing light and shapes again, and future applications for epilepsy, depression, and chronic pain. That medical-first strategy is not just ethical, it is practical. It provides a regulatory pathway, real-world safety data, and a reimbursement model that pure consumer wearables lack. Once implants prove they can safely restore function for millions, Hodak argues, expansion into broader computing becomes inevitable. Industry watchers will be listening closely for updates on Science Corp's clinical progress, manufacturing scale-up, and timeline for next-generation implants. What to expect at Disrupt 2026. TechCrunch Disrupt 2026 will take place October 13-15 at Moscone West in San Francisco. The event is expected to draw thousands of startup founders, VCs, and operators for three days of stage interviews, startup pitches in Startup Battlefield, hands-on demos, and networking. Hodak's session will be part of the main stage lineup focused on the future of computing, AI, and frontier tech. Attendees can expect a candid conversation rather than a scripted keynote, including challenges around safety, ethics, privacy, and who gets access to brain technology. With Neuralink now implanting patients, Synchron advancing its stent-based system, and Big Tech investing in non-invasive neural wristbands and AI wearables, the timing could not be better for a reality check on where screen-free interfaces truly stand. How to attend and save. For founders, investors, and anyone tracking the next platform shift after mobile, Hodak's talk is being billed as must-see. TechCrunch says passes are currently discounted, with attendees able to save up to $200 if they register before September 25. After that deadline, prices increase ahead of the October event. With the screen era potentially coming to a close, Disrupt 2026 may be where its replacement gets its clearest roadmap yet. AndroGuider Team Articles written by the AndroGuider team.

Paradromics wins FDA nod to connect its BCI platform to personal devices.

Paradromics wins FDA nod to connect its BCI platform to personal devices. 2026-08-27 Brain-computer interface company Paradromics has secured a pivotal regulatory green light from the U.S. Food and Drug Administration to extend the compatibility of its BCI platform to personal devices, a move that signals a meaningful shift in how neural interface technology can be deployed and accessed in everyday settings. The clearance, confirmed this week, positions Paradromics as one of the first companies to receive explicit regulatory sanction for this class of device integration. What the FDA approval actually means. The FDA's decision to expand Paradromics' device compatibility framework is notable not simply as a business win but as a regulatory precedent. Until now, BCI systems approved for clinical use have largely operated within closed, proprietary hardware ecosystems - purpose-built devices that rarely communicate with the smartphones, tablets, or laptops that patients already own. By granting Paradromics the authority to interface its BCI with personal devices, the FDA is effectively acknowledging a new category of connected neural technology, one where the boundary between clinical hardware and consumer electronics is deliberately blurred. For regulatory affairs professionals across the industry, this approval will become a closely studied template for future submissions seeking similar connectivity permissions. The technology and its implications. Paradromics has long focused on high-bandwidth neural data acquisition, aiming to build systems capable of reading and transmitting neural signals with sufficient fidelity for practical communication and control applications. Extending that capability to personal devices introduces a new layer of practical utility: users could theoretically interact with their own phones or computers directly through their neural interface rather than through dedicated clinical terminals. This kind of ambient usability has been a long-standing goal in the BCI field, but regulatory hesitance around cybersecurity, data privacy, and device safety has historically kept it out of reach. The FDA clearance suggests that Paradromics has addressed enough of those concerns to satisfy regulators, though the specifics of any conditions or labeling requirements attached to the approval remain important details for the industry to monitor. Market context and the road ahead. This development arrives at a moment when the broader BCI sector is navigating intense scrutiny around long-term viability, safety, and real-world usability. Competitors including Synchron and Precision Neuroscience are pursuing their own connectivity and usability expansions, meaning Paradromics' regulatory win could accelerate a race toward personal-device integration across the field. For payers, hospital systems, and rehabilitation technology buyers, the ability to connect a BCI to existing personal hardware also carries meaningful cost implications, potentially reducing the infrastructure burden associated with deploying neural interface technology at scale. As the FDA's comfort with connected neural devices continues to evolve, Paradromics' clearance may well mark the opening of a new regulatory era in which the personal device becomes a standard component of the BCI ecosystem.
