Wow, this is just Nuts! Moments ago, Trump's White... House Press Secretary Karoline Leavitt , when asked about Trump potentially abolishing the Department of Education, seems to say that science, social studies, s3x education, physical education, history, spelling, and other subjects shouldn’t be taught in schools in America. Seriously? Specifically she says: “As a mother of a child, I want an education system that helps my child read and write, teaches him math. NOTHING ELSE IN THE CLASSROOM.”show more

🚨 AI JUST DESIGNED A MATERIAL STRONGER THAN STEEL,... LIGHTER THAN FOAM AND UP TO 5× STRONGER THAN TITANIUM. Researchers used machine learning to discover entirely new microscopic lattice structures that were then 3D-printed into carbon nanolattices. The result is a mechanical metamaterial that combines properties previously thought to be impossible together: extreme strength with ultra-low weight. Why this matters: • Aerospace and automotive industries could build dramatically lighter vehicles and aircraft without sacrificing strength • Construction and infrastructure could use stronger, lighter components • Medical implants and protective gear could become both tougher and more comfortable • It proves AI can now design physical matter at the structural level exploring geometries no human engineer would have thought of The deeper implication is huge: We are moving from discovering materials that already exist in nature… to inventing entirely new classes of matter with properties we specify. AI isn’t just writing code or generating images anymore. It’s helping us build the physical world from the inside out. What industry do you think will be transformed first by these AI-designed super-materials? Follow for more frontier science and future technology.show more

OPTIMUS IS TESLA’S MOST IMPORTANT PRODUCT FOR HUMANITY’S FUTURE... Elon Musk has repeatedly said that Optimus will be Tesla’s biggest product ever — bigger than the car business. Here’s why it matters so much: • It will take over dangerous, repetitive, and physically exhausting jobs (mining, construction, factory work, disaster response) so humans don’t have to. • It will help solve the global caregiving crisis by assisting the elderly and disabled with daily tasks and companionship. • It creates real abundance — when physical labor becomes extremely cheap and scalable, the cost of goods, housing, and services drops dramatically for everyone. • Long-term, Optimus becomes the workforce that builds and maintains cities on the Moon and Mars. This isn’t about replacing humans. It’s about freeing humans from drudgery so we can focus on creativity, exploration, and meaning. Elon Musk on Optimus: “Optimus will be the biggest product ever.” The age of helpful humanoid robots is no longer science fiction. It’s already beginning inside Tesla factories — and it’s moving fast.show more

🚨 SCIENTISTS MAY HAVE FOUND A WAY TO DESTROY... VIRUSES WITH SOUND Researchers in Brazil report that high-frequency ultrasound was able to physically damage and destabilize both COVID-19 and influenza viruses in laboratory experiments. Not with chemicals. Not with drugs. With vibration. The idea sounds almost futuristic: target the virus at the exact frequency where its outer structure begins to resonate… until the оболope becomes unstable and ruptures. Like an opera singer shattering glass but at the microscopic level. What makes this so fascinating is that the attack isn’t aimed at the virus’s genetics… it’s aimed at its physical structure. Its shape. Its resonance. Its mechanical weakness. If this technology continues to develop, future medicine may start combining: AI-guided ultrasound targeting non-invasive antiviral therapies precision acoustic medicine frequency-based treatments We may be entering an era where sound itself becomes a medical tool. And that changes how we think about fighting disease entirely. Follow for more future science and medical breakthroughs.show more

Yesterday at Brown University ICERM's workshop on “Agentic Scientific... Computing and Scientific Machine Learning” I spoke about “Adaptive Swarms Across Scales”, making the case for scientific AI as systems that can create representations, stress them, fracture them, and enlarge the category in which future representations live. The category here is a composable and breakable working universe of science: data, hypotheses, simulations, measurements, tools, failures, figures, papers, provenance, and the transformations that connect them. Discovery happens when those transformations become executable, inspectable, composable, and capable of changing the world model they operate within. Atomistic modeling gives one category - states, forces, trajectories, observables, boundary conditions, conservation laws. Neural surrogates learn fast morphisms inside or between such categories. But discovery is higher-order: it changes which objects and morphisms are available in the first place: what variables exist, what operations are allowed, what evidence counts, what scale is active, what invariant is being preserved, and what kind of explanation the system is even capable of forming. This is scientific method as adaptive architecture: compression, stress, fracture, recomposition. Fracture matters here because it makes the logic physical: a non-commuting diagram realized in matter. The imposed load, material hierarchy, defect field, and assumed continuum description no longer map cleanly into the observed outcome. The crack is the obstruction and it identifies where the old morphism failed and where a new representation must be introduced. The physical crack and the categorical obstruction are the same event viewed in different substrates. ScienceClaw × Infinite is a machine for constructing and transforming a category of scientific artifacts. Each artifact is typed. Each operation has lineage. Each failed branch remains in the category as reusable structure. The “paper” is no longer the terminal object of science; it is one projection of a larger compositional trace, and it can be generated at any time for consumption by a human or an AI. With that the unit of scientific labor is changing. For most of the twentieth century the unit was the result (a measurement, a theorem, a synthesized molecule). It is now becoming the algorithm that produces results, and after that, the substrate of discovery itself. The static PDF is the wrong terminal object for this regime, and the role of the scientist with it. We now design algorithms that build algorithms, and eventually substrates in which such algorithms compose themselves. At that point, the scientist is no longer outside the discovery system. The scientist becomes one of the representations the system can transform. In that sense, the systems will eventually do science to us, and that is the structural consequence of the principle they are built on.show more

🚨 DIAMOND IS ABOUT TO REPLACE SILICON IN NEXT-GEN... CHIPS. Scientists are now producing large single-crystal CVD diamond wafers that could revolutionize electronics. Diamond conducts heat 5× better than copper and over 10× better than silicon while also handling extreme voltages, high frequencies, and radiation. Why this matters: • Thermal Superpower: Diamond acts as its own heat sink, solving one of the biggest problems in high-power chips • Ultra Wide Bandgap: Handles massive voltage and extreme temperatures without breaking down • High Frequencies: Electrons move incredibly fast, perfect for 6G, radar, and advanced telecom • Radiation Hardness: Ideal for satellites, space tech, and nuclear applications The deeper implication is massive: We’re at the early stages of a materials revolution. As silicon hits its physical limits with heat and power, diamond one of the most extraordinary materials in nature could power the next era of AI chips, electric vehicles, and aerospace systems. What do you think will diamond semiconductors become mainstream in the 2030s? Follow for more frontier materials science and future technology.show more

Do your nervous system a favor This looks ridiculous.... The science is solid. When you inflate your cheeks fully, you create increased pressure inside your oral cavity and nasopharynx. That pressure pushes gently against the tissues that sit right alongside the vagus nerve as it passes through your throat and behind your palate. It’s a mild version of the Valsalva maneuver — the same technique ER doctors use to slow dangerously fast heart rates. You’re creating internal pressure that directly stimulates your vagus nerve without any equipment, any training, or any special technique. The slow release through barely parted lips extends the stimulation. As the air seeps out gradually, it creates a prolonged, gentle exhale — which is the single most effective breathing pattern for activating your parasympathetic nervous system. A longer exhale tells your brainstem to slow everything down. And the physical act of puffing your cheeks stretches the buccinator muscles in your face, which are almost always tensed during stress. When they stretch and then release, facial tension drops — and your brain reads a relaxed face as evidence of safety. Three things in one silly move: vagal stimulation, extended exhale, and facial tension release. Puff up. Hold 3-5 seconds. Release as slowly as possible. Do it 3 times. Your heart rate will be noticeably slower by the third one. Nobody said nervous system regulation had to look dignified.show more

🚨 CHINESE SCIENTISTS JUST INVENTED 3D PRINTING THAT CREATES... OBJECTS IN 0.6 SECONDS USING ONLY LIGHT. Researchers at Tsinghua University have developed a new method called DISH (Digital Incoherent Synthesis of Holographic light fields) that can print complex millimeter-scale objects almost instantly. Instead of slowly building layer by layer, the system fires thousands of precisely patterned light images from multiple angles into a still vat of liquid resin. Where the light overlaps, the resin instantly hardens into a solid 3D object. The entire process takes just 0.6 seconds. Why this matters: • It’s currently the fastest volumetric 3D printing method ever demonstrated • Achieves extremely fine detail features thinner than a human hair • The resin stays completely still, so there’s no vibration or distortion • It can work with watery (low-viscosity) resins, making it suitable for biological applications • The team has already printed complex structures like blood vessel-like tubes and even a tiny bust of a historical figure The deeper implication: Traditional 3D printing has always been limited by speed and the need to move either the print head or the resin. This approach removes both constraints by using light itself as the sculptor. Because it can print directly into still liquid (and potentially onto living tissue), it opens new possibilities in bioprinting, medical devices, and rapid manufacturing. If the technology can be scaled beyond millimeter sizes, it could fundamentally change how we think about making physical objects turning “print” from a slow process into something closer to instantaneous fabrication. We’re moving from “layer by layer” to “all at once.” How do you think instant volumetric 3D printing like this could change medicine, manufacturing, or everyday life if it becomes widely available?

In 1504, Michelangelo finished a sculpture that contained a... fact medical science would not catch up with for another 124 years. No doctor noticed it for centuries... The sculpture is the David, in the Galleria dell'Accademia in Florence. The fact, hidden in plain sight on his neck, was finally observed in 2019 by an American cardiologist named Daniel Gelfman, a clinical professor at the Marian University College of Osteopathic Medicine. Gelfman had gone to the museum like millions of visitors before him. But where most people see a perfect male body carved out of stone, he saw something only a heart specialist could see: the external jugular vein on the right side of David's neck is distended, raised visibly above the collarbone, exactly as it would appear on a real human being in a state of intense physical excitement. In ordinary anatomy, this vein is not visible. It only stands out under specific conditions — adrenaline, fear, exertion, the cardiovascular surge that comes before great physical effort. In other words, exactly the state a young man would be in moments before facing a giant. Gelfman published the finding in JAMA Cardiology, one of the most respected medical journals in the world. He called it the David Sign, and noted that it had been hiding in plain sight for more than 500 years. What makes this detail extraordinary is when Michelangelo carved it... The mechanics of the human circulatory system — the way blood actually returns to the heart through the venous network — were not formally described until 1628, when the English physician William Harvey published De Motu Cordis. Michelangelo finished David in 1504. He had sculpted, with anatomical precision, a circulatory phenomenon that medicine would not understand for over a century. "Michelangelo, like some of his artistic contemporaries, had anatomical training," Gelfman wrote. "I realized that he must have noticed temporary jugular venous distension in healthy individuals who are excited." He had. And he carved it into the marble. His contemporaries knew they were watching something more than a sculptor at work... They called him Il Divino, the divine one. In a letter dated September 1537, the poet Pietro Aretino wrote: "The world has many kings, and only one Michelangelo." If you enjoyed this, I write a weekly newsletter read by over 50,000 people who love rediscovering the beauty of the past.

Three more replications of diamagnetism in LK-99 A re-cap... of who they are and where to find them: Andrew McCalip working out of the Varda Space Industries laboratories has replicated the apparent diamagnetic properties of LK-99 in the video attached. He did so following the recipe originally published by the Korean team using tools like a blowtorch and oven. Here you can see a fuller clip he has uploaded to youtube and also posted to his twitter / X account: Chrześcijańska Unia Jedności 🇳🇨🇯🇵🇮🇳🇬🇧🇬🇱 in Poland has also claimed replication of diamagnetic properties although a write-up is forthcoming, see photo in the comments. A team of Hao Wu, Li Yang, Bichen Xiao, Haixin Chang at the Huazhong University of Science and Technology have claimed successful replication of diamagnetism in a sample of LK-99 with a more extended write-up which is available on arxiv: with photos attached in comments below. This comes in addition to the first reported replication of diamagnetism which to the best of my knowledge belongs to Iris COMMS OPEN (2/3) Вы/ж. р. , in addition to now several others at Chinese research universities. ~~~~~~~~ An emerging interpretation of this physical phenomenon of partial levitation is that the superconducting pathways inside the material are one-dimensional, and so do not fully support levitation in all three dimensions. Normally in a Type-II superconductor current can flow and be conducted internally in different directions however the magnetic field might induce it, as well as trap or pin magnetic flux lines internally, thus the Meissner effect might be considered the combination of several phenomenon and properties at once. Notably, replications of this partial levitation / diamagnetism have been accompanied with photos of it NOT being attracted to a magnet, showing that this is not simply a magnetized flake of material. The speed and ease of replicating the diamagnetism of LK-99 is profound - normally in preparing these materials there is an extensive amount of artisinal expertise and practical know-how required to get the recipe just right. Things are definitely getting interesting here folksshow more
