Neuralink just solved a very serious brain-interface problem. Through-dura electrode implantation. The dura is basically the brain’s armor. Tough enough that surgeons normally cut through it with a scalpel. Neuralink inserted electrode threads straight through the dura and into the cortex while keeping the dura intact. Tiny threads.

How does the Neuralink implant connect to the brain? Tiny threads smaller than a human hair get inserted into your brain by a surgical robot. The idea is that the small and flexible threads minimize trauma and allow the brain to move naturally. Zack was one of the most passionate people at Neuralink. #Neuralink #BrainChip #BCI #FutureOfTech #FutureIsNow

OPINION: WILL NEURALINK LET HUMANS KEEP UP WITH SUPERINTELLIGENT AI? The truth is simple. In the next five to ten years we could have AI thousands of times smarter than any human. Our brains are amazing, but they are slow compared to AI. We speak about 150 words a minute and type even slower. Super intelligent AI will think and solve problems at speeds we cannot imagine. Neuralink is a solution. That amazing, tiny implant connects your brain directly to computers. You think and the machine responds instantly, no more slow keyboards or speech. More than a dozen people already have Neuralink implants. Some who were fully paralyzed are now playing video games, designing 3D models, and controlling computers just by thinking. Elon says the next steps are real telepathy and downloading knowledge straight into your brain. The plan is not to beat super intelligent AI in a race we cannot win. The plan is to team up with it. A high-speed brain link lets our human creativity, emotions, and values guide the AI while we get its incredible power. In the future, will there be a day without Neuralink, most people get left behind?

Elon Musk just made every skill you’ve ever earned sound like a waste of time. Musk: “Down the road with a Neuralink, you can just upload any subject instantly. You wanna fly a helicopter? No problem. Any given skill, you just upload it instantly.” Not faster learning. Not better education. Instant upload. The surgeon who spent 12 years learning to cut. The pilot who logged 5,000 hours learning to fly. The attorney who gave a decade to case law. Their entire advantage erased in a software update. We built civilization on one assumption. That knowledge is earned through suffering. That the distance between who you are and who you want to be is measured in discipline and years. Neuralink doesn’t close that distance. It deletes it. And what that kills isn’t employment. It’s identity. We don’t just use skills. We become them. Ask a surgeon who they are. They don’t say “I work in medicine.” They say surgeon. Ask a pilot. They say pilot. The identity was never the skill itself. It was the cost of acquiring it. If everyone can upload surgery in seconds, no one is a surgeon anymore. The skill still exists. The meaning behind it doesn’t. For centuries we told ourselves that mastery is what builds character. That the hardest thing you ever earned is the closest thing to purpose you’ll ever find. Neuralink doesn’t threaten your career. It threatens the story you tell yourself about why your life matters. The question nobody wants to sit with isn’t whether Musk can build this. It’s who you are when the thing that took you 20 years to become can be downloaded in 20 seconds.

No surgery. No wires. No brain implant. A retainer that controls your iPhone with your tongue. This is MIT's 0.7mm answer to Neuralink. The startup Augmental built a device called the MouthPad. Founder Tomás Vega designed it as a dental-grade smart retainer. It sits on the roof of your palate. A capacitive trackpad reads tongue movement as input. Users swipe, tap, and type completely hands-free. The device runs about 9 hours per charge. Augmental reports 100+ users already deployed in the field. Neuralink requires skull surgery to read brain signals. This approach grants similar independence with zero medical risk. It serves people with spinal cord injuries and paralysis. Sometimes the smartest answer skips the operating room entirely. QUESTIONS: Where else do we reach for surgery when simpler tools exist? What makes assistive tech go from clever demo to daily lifeline?

Tesla is engineering safety right into the Cybercab! A Tesla employee in a production Cybercab simulated a drop-off and pick-up near downtown Austin. He exited from the passenger door, re-entered from the passenger door, and slid over to the driver’s side. The Cybercab’s seats have no middle obstruction, which allows an easy slide across to either side. This makes it safer to exit while avoiding oncoming traffic. The Cybercab can also park very close to the curb and open its butterfly doors upward to avoid scrapping or hitting the curb. This could make it safer to get in and out in certain situations. 📷 Adan Guajardo

Neuralink Integration with ANKTIVA for Revolutionary Immunotherapy Elon Musk, a visionary collaboration opportunity by Dr. Sarabi and Grok. Dear Mr Musk: Good morning sir! I would like to bring to your attention the remarkable work of Dr. Patrick Soon-Shiong, who has developed a groundbreaking therapy, Anktiva, capable of supercharging key immune molecules to combat cancer and COVID-19. In a recent discussion with Tucker Carlson, Dr. Soon-Shiong described this advance as akin to the “E=mc²” of medicine—the discovery of “God’s equation,” a biological key that has eluded us for half a century until now. Just as Tesla has revolutionized the automotive and environmental industries, and SpaceX has advanced the expansion of humanity into a multi-planetary species to ensure our long-term survival, Anktiva represents a comparable paradigm shift in medicine, safeguarding human health and endurance. Given your shared commitment to advancing humanity, I respectfully inquire whether you might consider extending your support to Dr. Soon-Shiong in this critical pursuit. Moreover, I propose exploring the integration of Neuralink, employing the stepwise protocol outlined below, in collaboration with Dr. Soon-Shiong. Such a partnership could propel an unprecedented advancement in medicine and the future of humankind. Grok has developed a preliminary conceptual integration of Neuralink to enhance and supercharge IL-15 production 1/7: Identify Target Neural Circuits • Map the hypothalamic paraventricular nucleus (PVN) and dorsal motor nucleus of the vagus • Trace efferent projections from the PVN to the intermediolateral cell column (IML) in the spinal cord. • Identify sympathetic nerve fibers innervating the spleen and lymph nodes. • Map vagus nerve branches terminating in gut-associated lymphoid tissue and the hepatic portal system. 2/7: Implant Neuralink and Integrate with Neural Pathways • Place Neuralink electrodes in the PVN and dorsal motor nucleus of the vagus, using extended threads for subcortical/brainstem access. • Configure for recording/stimulation to modulate autonomic outflow to the IML at thoracic spinal levels. • Establish central control over peripheral pathways (e.g., splenic/vagus nerves) via targeted brain stimulation. 3/7: Develop Stimulation Protocols • Program Neuralink for high-frequency stimulation to the PVN for sympathetic activation. • Apply low-frequency patterned stimulation to the dorsal motor nucleus to engage feedback loops. • Modulate splenic/vagal pathways with phase-locked cycles through central interfaces. 4/7: Initiate Immune Cell Activation • Stimulate pathways to induce IFN-γ and TNF-α release in spleen/lymph nodes. • Trigger IL-15 transcription/translation in dendritic cells, monocytes, and epithelial cells. • Monitor for increased membrane-bound IL-15/IL-15Rα complex formation. 5/7: Enhance Local IL-15 Presentation • Concentrate stimulation at tumor/inflammation sites. • Promote immune cell clustering via chemokine/adhesion molecule induction. • Sustain localized IL-15/IL-15Rα trans-presentation to NK and CD8+ T cells. 6/7: Implement Real-Time Monitoring and Feedback • Record neural/immune biomarkers continuously via Neuralink telemetry. • Adjust stimulation based on IL-15 levels and NK/T cell activity. • Set safety thresholds to avoid excessive immune activation. 7/7: Synchronize with Immunotherapy • Time stimulation with IL-15 superagonists or adoptive therapies. • Evaluate synergies using immune monitoring/imaging. • Optimize based on patient responses.

Once again, the Black Skimmer is demonstrating the wonders of aerodynamics. Each twist of the body, each individual feather helping steer while a wall of crashing white water rumbles just behind the bird’s outstretched tail. Like a surgeon’s scalpel, the bird’s lower beak surgically slices through the water with utmost care and precision in hopes of coming into contact with a poor, unsuspecting fish. This attempt might have been unsuccessful, but it doesn’t seem like the bird has a care in the world. It just keeps skimming through the shallows, waiting for that tasty morsel to graze its outstretched beak. So remember, when failure raises its head and stares you in the eye. Just keep skimming because eventually you’ll succeed just like the magical Black Skimmer.

🚨 SCIENTISTS ARE USING AI TO MAP A HIDDEN “CLEANING SYSTEM” INSIDE THE HUMAN BRAIN AND IT COULD CHANGE HOW WE UNDERSTAND SLEEP, AGING, AND NEURODEGENERATIVE DISEASE. It’s called the glymphatic system a vast network of fluid channels that flushes toxic waste from the brain while you sleep. For years it was almost impossible to observe in detail. Now AI-powered imaging is revealing it like a living galaxy of microscopic rivers and pathways inside neural tissue. Why this matters: Your brain produces toxic proteins constantly. The glymphatic system is one of its primary waste-clearance mechanisms clearing the very proteins linked to Alzheimer’s, Parkinson’s, and other neurodegenerative diseases. But here’s the unsettling part: This cleaning system becomes dramatically less efficient with age, poor sleep, stress, and brain injury. Sleep may not just “rest” your mind it may literally wash your brain. The deeper implication is staggering: The brain isn’t just a computer. It’s a dynamic, living network that constantly rebuilds and cleanses itself in real time. The more we map it, the more it looks like an entire universe of connected energy flows inside our skulls. What if some neurological diseases begin when the brain can no longer properly “wash” itself at night? Follow for more frontier neuroscience and future technology.

I love your observation and it will make me discuss the remarkable adaptations that prevents giraffes from passing out and suffering brain damage when bending to drink water and when standing up. ADAPTATION 1 Did you know that the distance from the giraffe's heart to its brain is about 2 meters or more? That's more than the average humans height! Pumping blood up to that great distance and working against gravity is not a joke! That's where the giraffe's heart comes in. A giraffe's heart is unique in several ways. First, it is quite large, weighing up to 11kg and measuring about 2 feet long, which is necessary to pump blood up the long neck to the brain. Second, it has thick walls to generate enough pressure to overcome gravity and push the blood up to the head. ADAPTATION 2 Now, let's move to the neck. Before discussing the incredible roles the valves in the jugular veins perform, let's look at what can happen without them, and then the solution. Problem I: When the giraffe bends down to drink, blood rushes downward to the head. Gravity pulls a huge volume of blood toward the brain, which could cause dangerously high pressure in the head and potentially burst vessels or cause other damage. Solution: They have one-way valves in the jugular veins (the large veins in the neck). These prevent blood from rushing backward uncontrollably into the head when lowered. These valves help regulate and slow the downward flow, avoiding a massive pressure surge to the brain. Also, the neck veins can act as temporary blood storage unit, storing over 1 litre of blood. This prevents blood from flooding the brain and also reduces the amount of blood returning to the heart. As a result, the heart pumps with lower pressure while the head is lowered. This buffers the high head pressure that gravity would otherwise cause. Problem II: When they raise their head up immediately after drinking, blood pressure drops sharply to the brain. A sudden drop could starve the brain of oxygen, causing fainting. This is similar to but much more extreme than the dizziness some people feel when standing up quickly. Solution: When the giraffe raises its head, that stored blood rushes back to the heart quickly. The heart responds with a strong, high-pressure beat that immediately pushes blood back up to the brain, preventing a dangerous drop in cerebral pressure. Impressive right?!

WOW v14.3.2 is very decisive and is able to execute with great confidence. Big fan. That said, in my first drive it messed up *spectacularly* twice in <15 miles of suburban driving. In one instance, it swerved out of its through lane of traffic into a lane that was ending, right as it was ending. It was not trying to overtake any vehicles, it just swerved over violently. ugh The other, in the video below, it did not consider that the left lane was turn-only, and tried to use it overtake other vehicles while their light was red. (this intersection begins with left turn green and through-lanes red) It is still very slow to merge into the proper lane in time for a turn, and ended up cutting off a large truck to make its turn. Could it have completed its maneuvers and continued without intervention? Yes. Would it be safe or legal to do so? No. Plenty of work left to do on FSD.

Admin Post: This is a T Puller. It's really hard to pull a door closed from a wheelchair and these make it much easier. They stick on the door on the hinge side. I just flip it out and use it to pull the door until I can reach the knob. In the past I've used pull ropes but I still had to go through, turn around, wheel back in to get close enough to grab the rope and then back out. Chesnyy could also grab and pull a rope but there needed to be room for her to maneuver and at times she's not at the door with me (especially if I'm taking another dog out) or she might be carrying something. T Pullers make the house a bit easier for me. #Accessibility Video description for inclusivity: and open door that leads out to a deck. There is a small black handle on the inside. A hand reaches out and flips it out and uses it to pull the door almost closed, then grabs the door knob.

Some microbes carry a protein, called SNIPE, that "chops up" phage DNA as it's being injected into the cell. This is a new mechanism for phage defense! CRISPR–Cas and restriction enzymes also evolved to fight against phages, but they work by recognizing sequences. SNIPE works, instead, by sensing "touch." SNIPE is a protein with about 500 amino acids. After it's made by the ribosome, it latches onto ManYZ, two proteins which sit on the cell's inner membrane. (ManYZ is an importer; it brings mannose and other sugars into the cell.) Once attached to ManYZ, SNIPE sits and waits for an invading phage. Some phages, including lambda, actually infect cells by pushing their DNA through this ManYZ channel. Lambda uses its "tail" to reach inside the protein channel, basically, and inject its DNA. When this physical touch happens, though, SNIPE is waiting. As soon as the phage DNA starts entering the cell, and passes through ManYZ and SNIPE, it gets immediately destroyed. This means that SNIPE is the first phage defense system discovered, so far, that uses spatial positioning at the injection site to destroy invaders. But there are caveats, of course. If you untether SNIPE from ManYZ, such that it can freely diffuse through the cell, it will chew up the bacterium's genome. It is not a highly discerning nuclease! Also, SNIPE is not found in most bacteria. A prior pangenome study, which sequenced lots of different microbes, found that roughly a third of well-studied bacterial lineages had at least one member with a SNIPE-like protein. (For this paper, they just ported one of those homologs into an E. coli laboratory strain.) And finally, because SNIPE's mechanism is tightly tied to ManYZ, it cannot be used to defend against phages that enter the cell through different routes. T4 phages, for example, inject their DNA straight through the cell membrane and into the cytoplasm, without interacting with ManYZ. This is a nice basic science paper. Applications TBD. (Just remember that scientists figured out that bacteria had a phage defense system, called CRISPR-Cas, many years before it was repurposed into a gene-editing tool.) P.S. The video below shows how cells with the SNIPE gene (middle row) kill invading phages, and thus continue growing and dividing. Empty vector (top row) refers to bacteria carrying a plasmid with no SNIPE gene; this is a control group. And SNIPE E414A refers to cells which received a mutated SNIPE gene, where the glutamate at position 414 has been changed to an alanine, thus destroying the protein's nuclease activity. These cells also die when they get infected with a phage.

Some microbes carry a protein, called SNIPE, that "chops up" phage DNA as it's being injected into the cell. This is a new mechanism for phage defense! CRISPR–Cas and restriction enzymes also evolved to fight against phages, but they work by recognizing sequences. SNIPE works, instead, by sensing "touch." SNIPE is a protein with about 500 amino acids. After it's made by the ribosome, it latches onto ManYZ, two proteins which sit on the cell's inner membrane.

This woman is ripping her mail into little pieces. Like she says, we all grew up with the warning that people could go through our trash and still our information. 💯 I do this very thing still today. I have a shredder but I still prefer to rip everything up because the darn shredder always jams and sometimes I don’t want to walk all the way over there. 😂 Don’t do this as well? Was it also ingrained into your mind to tear up all your mail into a hundred pieces?

Iberia’s first Starlink plane went live. Madrid to São Paulo with WiFi that actually works. Free for everyone on board. No cabin tiers. No hourly meter. No watching one email load like it is crossing the Atlantic by canoe. Speeds can hit around 450 to 500 Mbps. Basically home broadband at cruising altitude. This is only the first plane. Iberia wants Starlink on 35% of its long-haul fleet by year-end, while IAG plans to fit more than 500 aircraft across British Airways, Aer Lingus, and Vueling. Airline WiFi finally stopped being a prank. Starlink / Writer: Annette, Designer: Janné

Lakhs of devotees have embarked on the sacred Amarnath Yatra, proceeding with unwavering faith through the Pahalgam and Baltal routes. No power on earth can halt this divine journey of devotion. You questioned our faith in Pahalgam and responded with bullets. Bharat answered with resolve. Today, the world witnesses countless devotees are treading that very path to seek the holy darshan of Lord Bholenath. This is not just a yatra, it is a testimony of our unshakable faith and timeless Sanatan spirit.

There's something about design that truly makes me happy. Before I was diagnosed with a complete SCI, I loved building thing with my hands and trying to make them unique and beautiful. The accident didn't just take my mobility, it robbed me of my creative drive. I didn't I would ever get that back that was up until Neuralink came into the picture. I was very serious about applying but just couldn't bring myself to do it. Then Noland Arbaugh comes into the picture and I see his video and I saw how passionate he was toward the whole ide and that was like a switch. I want to thank Noland because if I hadn't seen that video I wouldn't be typing this message with my thoughts. So the day I gained control of the device I had the guys install Autodesk Fusion and the first night I had my first part designed by BCI. I have been designing things non-stop since. Now lets talk tools and the first one is the ArcDroid it is a CNC robot that holds a plasma torch and can cut profiles in sheet metal. I have made numerous signs, letters and parts with this and i love it. I have also had the chance to help the local high school install and setup their CNC plasma table. I love being able to share my knowledge with others and show new technology to kids that want to learn. The next one everybody is more familiar with is the Bambu Lab X1C. It is my first 3D printer and I had no idea how dang handy these things were! I can go from thought, Neuralink, Fusion, X1C and poof! You have your part all in a matter of like a hour. I make everything from parts for my wheelchair or RC ✈ to toys for my nephew. These devices have completely changed my life. I now have my creative outlet back and I'm not done looking for new things to try. I'm thinking a laser next!!!😎 Thank you Elon Musk for the opportunity to showcase my skills, I'm extremely grateful🙏
