What looks like a server boiling underwater is actually... one of the most advanced cooling technologies used in modern computing This demonstration showcases a two-phase immersion cooling system, a method increasingly explored for high-performance computing and AI infrastructure where traditional air cooling becomes less efficient. Instead of using fans to move heat away, server components are submerged in a specialized non-conductive dielectric fluid that safely surrounds the electronics without causing electrical short circuits. As processors generate heat, the liquid absorbs thermal energy and begins to boil directly at the component surface.show more

Satya Nadella: Microsoft’s latest Wisconsin AI data center keeps... yearly water consumption no higher than that of 1 local restaurant. "The cooling loop is filled once and the data centre can operate effectively with zero water consumption. Daily water usage across a year is roughly equivalent to what a single restaurant would use" The mechanism is mainly about replacing evaporative cooling with closed-loop direct-to-chip liquid cooling, so water moves like coolant inside a sealed machine rather than being boiled off into the air. Hot GB200-class AI racks produce too much heat for normal air cooling, so cold liquid is pushed through pipes into the servers and across metal cold plates touching the hottest chips. The liquid enters the rack cool, absorbs heat from the chips through cold plates, then exits the rack at a higher temperature and carries that heat through pipes to a huge cooling system outside the compute floor. Microsoft says Fairwater sends that hot water to cooling “fins” beside the datacenter, where 172 20-foot fans blow air across the fins and dump the heat into the outside air. The important detail is that the air cools the water through metal surfaces, so the water does not need to evaporate the way many older datacenters use cooling towers. The cooled liquid then returns to the servers, repeats the loop, and keeps absorbing heat from the chips. In older data centers, heat is often removed partly through cooling towers. Hot water meets moving air, some water evaporates, and that phase change carries heat away. Effective, but it consumes fresh water continuously. But Firwater is a closed loop because the same coolant keeps circulating through sealed pipes: it absorbs heat from the chips, releases that heat through radiator-like fins, then flows back to the chips again. For Wisconsin Fairwater, Microsoft says more than 90% of the facility uses closed-loop liquid cooling, while the remaining portion uses outside air and switches to water only on the hottest days. ---- From "Microsoft" YouTube channel, (link in comment)show more

China just took AI infrastructure underwater. The country has... reportedly launched a wind-powered underwater data center near Shanghai, designed to cool AI servers using seawater instead of traditional cooling systems 🌊🤖 Around 2,000 servers are said to be sealed inside submarine-grade modules, helping reduce land use, water consumption, and cooling energy. The project is powered by offshore wind and built for AI workloads, big data, and large-scale computing. Why it matters? AI is creating massive demand for electricity, cooling, and infrastructure. If underwater data centers prove reliable, they could become a new way to scale AI while using less energy. But the challenge is huge: corrosion, maintenance, sea conditions, and long-term reliability still need to be proven.show more

Water usage has been a hot topic in the... AI data center world, but the numbers may surprise you. According to the Manhattan Institute, data centers use 0.2 percent of daily water usage in the U.S. and that number has dramatically decreased in the past few years due to a new method: liquid cooling. By moving to 45°C liquid cooling, AI factories in favorable climates can use dry coolers instead of conventional cooling-tower-based systems, cutting facility cooling water use from roughly 2.6M gallons per MW per year to near zero. Liquid cooling enables AI factories to be both water and energy efficient, while creating opportunities for heat reuse and dispersal to local communities, allowing these factories to become energy grid assets.

🚨 SCIENTISTS MAY HAVE JUST FOUND A WAY TO... CONTROL MAGNETISM USING ONLY LIGHT Researchers demonstrated “all-optical control” of antiferromagnetic materials — meaning magnetic states can now potentially be written and switched using ultrafast laser pulses instead of electric currents. Why this matters: Most modern computing systems rely on moving electrical charge. But future technologies may use “spin” instead of charge a field known as spintronics. Antiferromagnetic materials are especially exciting because they: • switch incredibly fast • consume less energy • generate almost no stray magnetic interference • could store massive amounts of data The problem? They’ve been notoriously difficult to control. Now scientists may have discovered a way to manipulate them using light itself. In simple terms: Future memory devices may one day write information at near-light speeds using ultrafast laser pulses instead of traditional electronics. This could eventually impact: • AI hardware • ultra-fast computing • next-generation memory • quantum technologies • energy-efficient data centers The future of computing may not just be electronic. It may become photonic and spin-based. Follow for more future physics and technology breakthroughs.show more

This looks like a regular IT server room. But... it is actually the main avionics compartment of an Airbus A350, a rare view into what sits at the very front of the aircraft, directly beneath the cockpit floor. Inside are 22 purpose built computing modules made by Thales, each costing more than $100,000+ They host multiple aircraft systems, processing everything from flight controls and landing gear to hydraulics, fuel, electrical systems and flight warnings. All of them are connected through a dual redundants AFDX network, with 14 switches and 29 remote data concentrators distributed throughout the aircraft. Keeping this computing architecture running requires an estimated 50-60+ kW of electrical power. The electricity keeping all of this computing hardware alive is generated in real time from the aircraft's two engines. Each engine mechanically drives two generators through its accessory gearbox, giving the A350 four generators capable of producing up to 100 kVA each. That electricity then flows through the aircraft's power network, where transformers and rectifiers convert it into the different AC and 28 V DC supplies the avionics need. And if those generators fail, the aircraft has layers of backup power, including the APU and, in an extreme emergency, a ram air turbine that deploys automatically if all systems fail. The A350 has two independent avionics cooling circuits, heat extraction fans and backup airflow paths to keep the computers within their operating limits. So the next time you hear the word autopilot, remember what it really takes to make an Airbus A350 fly itself, An entire architecture of computers, networks, redundant power and cooling, hidden beneath the floor where no passenger ever sees it.

🚨 SOUTH KOREAN SCIENTISTS JUST CREATED HOLLOW SILICON NANOTUBES... THAT TRAP HEAT AND TURN WASTE ENERGY INTO ELECTRICITY. Researchers at POSTECH have developed a new hollow silicon nanotube structure that dramatically reduces thermal conductivity. By turning solid nanowires into microscopic pipes, they trapped heat-carrying particles (phonons) inside the tubes, cutting thermal conductivity by 70% compared to solid wires. Even when both structures had the same surface area, the hollow nanotubes still ran 33% cooler. This phonon localization effect previously thought to require extreme cold or exotic materials was achieved at near-room temperature using simple silicon nanotubes. Why this matters: • Waste heat from data centers, EV batteries, factories, and electronics is currently lost this could capture and convert it into usable electricity • The technology uses abundant, cheap silicon instead of rare and expensive materials like bismuth and tellurium • It’s highly compatible with existing semiconductor manufacturing, making large-scale production more realistic • It solves a long-standing problem: silicon is great for chips but terrible for thermoelectric energy conversion The deeper implication: This breakthrough shows that clever nanoscale engineering can unlock new capabilities from ordinary materials. By controlling how heat moves at the atomic level, researchers are opening a path to more efficient energy recovery systems without relying on scarce resources. As AI and computing power keep growing, finding ways to recycle the massive amounts of waste heat they generate will become increasingly important. How significant do you think waste-heat recovery technologies like this could become in the next decade? Follow for more frontier materials science and energy innovation.show more

This is what happens when on-chain infrastructure meets real-world... engineering. PinLink has converted a fleet of air-cooled L9 miners into a fully hydro-cooled system, unlocking a new performance ceiling. Higher sustained uptime, tighter thermal control, and consistently stronger hashrate under continuous load. Hydro-cooling is an edge. It removes the inefficiencies that cap air-cooled systems and optimizes physical infrastructure. This is exactly how PinLink operates: pairing on-chain coordination with physical execution to deliver maximum performance from real assets. Watch the video to see the conversion in action.show more

🚨 IMPOSSIBLE MATERIALS Scientists may have just discovered the... next generation of magnetic technology. And it’s neither a normal magnet… nor a normal non-magnet. Researchers at the University of Tokyo are developing something called: “Altermagnets.” A completely new class of magnetic material. Traditional electronics rely on two known magnetic states: • ferromagnets • antiferromagnets But altermagnets behave differently. They combine properties of both. That means they could potentially deliver: • ultra-fast memory • ultra-low power electronics • high-density information storage • next-generation spintronic computing without many of the limitations current magnetic systems face. The deeper shift: Modern computing has largely been built around moving electrical charge. But the future may revolve around controlling electron spin itself. That changes everything. Researchers say these materials generate powerful internal “emergent” electromagnetic effects caused by the geometry of the material itself. Meaning: The structure of matter begins controlling electrons in entirely new ways. If this scales: • future computers become dramatically more energy efficient • magnetic memory becomes faster and denser • spin-based computing could rival conventional chips • entirely new forms of quantum electronics may emerge This is why some physicists are calling altermagnets the “third class” of magnetic material. Because they may open an entirely new branch of information technology. Question to audience: If future computers stop relying mainly on electrical charge… and start computing through electron spin geometry instead… does computing itself fundamentally change?

This looks like a simple transparent shock absorber filled... with oil. But what you are seeing is one of the most destructive phenomena in fluid engineering. This is cavitation in its true form. The white cloud forming beneath the piston is not foam and it is not air. The oil is literally changing from liquid to vapour at room temperature. When the piston moves rapidly, the oil is forced through tiny passages inside the damper. The fluid velocity increases, the local pressure drops, and if it falls below the oil's vapour pressure, the liquid begins to boil without any increase in temperature. The moment the pressure recovers, those microscopic vapour bubbles collapse almost instantly. And that is where the real damage begins. The destructive forces of cavitation is really not understood well by most. A collapsing cavitation bubble creates shockwaves and high-speed microjets that strike nearby surfaces with enormous local forces. Repeated millions of times, these tiny implosions can slowly eat away hardened metals, destroy precision components and reduce the lifespan of expensive machinery across industries. This same invisible phenomenon is one of the biggest challenges in naval engineering. Ship propellers operating under enormous loads can suffer cavitation erosion, losing efficiency while creating underwater noise. For advanced stealth submarines, that noise can become a major problem because cavitation can reveal their position. Decades of research have gone into specialised propeller designs, pump-jets, surface finishes and hydrodynamic optimisation to delay its formation. The same issues affects hydroelectric turbines that convert the energy of entire rivers into electricity, and industrial pumps that move oil, chemicals and water through critical infrastructure around the world. Perhaps the most remarkable part is that after 4-5 decades of advances in metallurgy, coatings and manufacturing, engineers still cannot simply build a material that is immune to cavitation. The solution is not to make stronger metals forever. It is to understand the fluid dynamics so precisely that cavitation is prevented before in those destructive bubbles ever form.show more

How did SpaceX film inside a 33-Engine Raptor inferno... without the camera melting? 🚀🔥 What looks like a camera melting inside a massive explosion is actually a masterclass in extreme aerospace engineering: SpaceX capturing close-up footage of its 33-Engine Raptor ring firing simultaneously. Instead of relying on standard commercial camera housings that would vaporize instantly, this setup uses heavy-duty, customized protective enclosures engineered to withstand thousands of degrees of intense heat and vibrational stress. Paired with optical-grade sapphire crystal viewports and active cooling systems, the lens remains entirely uncompromised as the engine cluster ignites into a blinding wall of fire. At a time when deep-space exploration requires pushed technical boundaries, this unbelievable footage proves that capturing the heart of a rocket blast no longer requires sacrificing the gear. Simply put: Bringing highly specialized thermal shielding to a high-speed camera setup marks a massive evolution in aerospace diagnostic engineering and launch documentation.show more

🚨 ITALY IS ABOUT TO GENERATE ELECTRICITY FROM A... FULL-SCALE NUCLEAR REACTOR THAT HAS ZERO NUCLEAR FUEL INSIDE IT. At the ENEA Brasimone research center, Newcleo has installed a 155-ton reactor vessel filled with molten lead. Instead of uranium, it uses electric heaters to simulate the heat from fission. The lead will circulate, transfer heat to a steam generator, and spin a real turbine to produce electricity. This is not a small lab experiment. The vessel is nearly the same size as the commercial 200 MW lead-cooled reactor Newcleo eventually wants to sell. Why this matters: • It’s one of the most complete non-nuclear demonstrations of a next-generation reactor ever attempted • By proving the molten lead cooling system, heat exchangers, and power conversion loop work at scale before introducing nuclear fuel, Newcleo is trying to de-risk the hardest and most expensive parts of advanced nuclear development • Lead-cooled fast reactors can operate at atmospheric pressure with high thermal margins and natural circulation decay heat removal • The company has ambitious plans, including partnerships in the US (with Oklo) to use surplus weapons plutonium as fuel The deeper implication: Traditional nuclear development is extremely slow and expensive because you have to deal with radiation, fuel, and regulatory scrutiny from day one. Newcleo’s approach flips this: prove the entire non-nuclear “machine” works first at near-commercial scale, then add the nuclear part later. If successful, this could meaningfully shorten development timelines and reduce technical risk for lead-cooled reactors. It’s still early the real fueled reactor isn’t expected until the early 2030s but this is one of the more serious and well-funded attempts to make a new type of advanced nuclear a commercial reality. How important do you think non-nuclear full-scale testing like this will be for accelerating advanced reactor deployment?

🚨 SCIENTISTS JUST BUILT A CHIP THAT CAN SEE,... THINK, AND REMEMBER ALL AT THE SAME TIME. And it works more like a biological brain than a traditional computer. Researchers at RMIT University have created a neuromorphic vision chip that mimics the human eye and brain. Unlike conventional systems that capture images and send data to external processors, this chip performs sensing, processing, and memory storage directly where the light hits. The active layer is thousands of times thinner than a human hair. It uses doped indium oxide to detect light, process the information on-chip, and retain what it sees over time without constant electrical refreshing. Why this matters: • It dramatically cuts energy use and latency by eliminating data transfer to separate processors • Enables much faster real-time decision making for autonomous systems • Works more like biological vision than traditional machine vision • Could power the next generation of efficient edge AI in vehicles, robots, and remote sensors The deeper implication: For decades, we’ve built vision systems by bolting cameras, processors, and memory together like separate organs. This chip collapses those functions into one biological-style unit. It’s a step toward machines that don’t just “see” but actually perceive and remember in a more efficient, brain-like way. If scaled successfully, it could become a foundational component for autonomous systems that need to operate intelligently with minimal power and minimal delay. We’re moving from cameras that take pictures to chips that truly see. How do you think neuromorphic vision chips like this will change what’s possible for self-driving cars and autonomous robots?

Before electricity reached every home, India had its own... way of staying cool. In parts of Rajasthan, grandmothers built a natural fridge using clay, cow dung, and grass. No wires. No bills. Just wisdom passed down through generations. Inside, milk stayed fresh. Curd set perfectly. Rotis stayed soft for longer. Even in the harsh desert heat. The secret lay in the materials. Porous clay allowed slow evaporation, cooling the air within. The khipra grass roof added insulation. What looks simple was actually science working quietly. Today, this “desi fridge” is slowly disappearing, especially in western Rajasthan. Replaced by modern appliances. Watch how our grandparents were sustainable long before it became a trend. Would you try going back to something like this?

🚨 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.

BREAKING: I have confirmation that the Israeli Air Force... used soft-kill weapons to cut electricity in Tehran and Karaj. Fortunately, none of the power plants were bombed. According to my sources in the IDF, the Israeli Air Force used CBU-94/B “Blackout” cluster bombs equipped with BLU-114/B soft-kill submunitions to induce electrical short circuits at multiple power plants and transformer stations, including those in the Pirouzi district of eastern Tehran. The aluminum filaments dispersed by these submunitions have adhered to wiring, transformers, and other electrical components, disrupting their function and preventing electricity generation. Once these materials are removed and affected components are cleaned and repaired, power can be restored in Tehran and Karaj. This action appears to have served as a warning to the Islamic regime of Iran and a test of its tolerance and response in the event of actual airstrikes targeting power infrastructure. #OperationEpicFury #OperationLionsRoarshow more

🚨 SCIENTISTS JUST INVENTED A WAY TO PRINT CIRCUIT... BOARDS WITH LIQUID METAL AND IT LOOKS LIKE SOMETHING OUT OF TERMINATOR. A startup called Itera has developed a system that can create working PCB prototypes in minutes instead of weeks. You upload your design, and electric fields force a liquid metal alloy into the exact shape of the traces on a glass substrate. The board is then tested and ready almost instantly. Why this matters: • Traditional PCB prototyping can take days or even weeks this could reduce it to minutes • It uses liquid metal instead of etched copper, making it potentially much faster and more flexible for rapid iteration • Backed by $12 million in funding, the company is already focusing on single-layer boards with surface-mount components • The process looks genuinely futuristic glowing rivers of metal flowing into place on command The deeper implication is enormous: We may be watching the beginning of a completely new era of hardware development. Instead of waiting days for a prototype, engineers and makers could design, test, and iterate multiple versions in a single afternoon. This could dramatically speed up innovation in electronics, robotics, AI hardware, and even consumer devices. What happens when making a new circuit board becomes as fast and easy as printing a document? Follow for more frontier physics and future technology.show more

The fascinating concept of Non-Newtonian fluids, which transition from... a liquid state to a solid-like state when pressure is applied, has a rich history that spans several centuries. The study and understanding of these peculiar fluids have evolved over time, leading to a wide range of practical applications and scientific insights. One of the earliest references to Non-Newtonian behavior in fluids dates back to the 17th century when Sir Isaac Newton formulated the basic principles of fluid mechanics. Newton's laws of fluid motion primarily applied to Newtonian fluids, which exhibit constant viscosity and flow behavior regardless of the applied force or pressure. However, it soon became apparent that not all fluids behaved in this predictable manner. In the mid-19th century, a scientist named Thomas Andrews made significant contributions to the understanding of Non-Newtonian fluids. Andrews conducted groundbreaking experiments with carbon dioxide, revealing that under high pressure, this gas could transform into a liquid. This observation marked one of the earliest instances of pressure-induced phase changes in fluids. The term "Non-Newtonian" itself was coined in the 20th century to describe fluids that did not adhere to Newton's classical laws of fluid dynamics. These fluids exhibited a variety of behaviors, but one of the most intriguing was their ability to solidify or increase in viscosity when subjected to stress or pressure. One of the most famous examples of such behavior is cornstarch mixed with water, which forms a substance known as "oobleck" that becomes more solid when pressure is applied. In the modern era, Non-Newtonian fluids have found applications in various fields, including food science, engineering, and material science. They are used in products like quicksand, body armor, and even in the development of impact-resistant materials. One of the key insights that emerged from the study of Non-Newtonian fluids is the importance of understanding the relationship between stress and strain, as well as the influence of time-dependent properties on their behavior. This knowledge has led to advancements in rheology, the study of flow and deformation in materials, and has practical implications in areas such as industrial processing, medicine, and the design of everyday products.show more

Heatwave Grips France and Europe! Europe is facing an... intense heatwave, with temperatures reaching close to 35-40°C in several countries. France has reported over 1,000 heat-related deaths, with older adults among the most affected. Due to legal complications and surging demand of air conditioners, coolers, and fans - shortages and huge price surge reported in many areas amplifying problem. Retailers have reported fast-selling cooling appliances as households scramble to cope with the extreme heat which price of fan rocketing to 70k in some areas. Meanwhile, French authorities and the EU urge people to use less AC to "protect the climate." In some EU countries, using your AC at home can even result in a fine. The extreme heat has also disrupted transport, strained power supplies, impacted agriculture, and lowered river levels across parts of Europe.show more
