💡 Scientists Made a Semiconductor That Can Be Reprogrammed With Light Most computer chips are born with a fixed job. Once a semiconductor is fabricated, its electrical properties are largely locked in. Researchers at Princeton have now created an ultrathin semiconductor — only a few molecules thick — that can repeatedly change how it conducts electricity in response to different wavelengths of light. The effect is reversible, meaning the material can be programmed, erased and programmed again. The team achieved this by combining a two-dimensional semiconductor with light-sensitive molecules that physically change shape when illuminated. Those molecular changes alter the semiconductor’s electronic and optical behavior. And unlike a simple binary switch, the response can be adjusted gradually rather than just flipped between “0” and “1.” The researchers have already produced uniform samples about one inch across and built arrays of programmable electronic switches. Their next goal is to connect them into functioning circuits. The broader idea is striking: instead of manufacturing a chip for one fixed purpose, future electronics might be able to change their own physical behavior after they are built. Software is already reprogrammable. Now the hardware itself is starting to learn the trick. #Semiconductors #Computing #MaterialsScience #Photonics #Technology #Science https://www.science.org/doi/10.1126/sciadv.aee1510

🧠 Singapore Just Opened a Data Center Powered by Living Human Neurons This sounds like science fiction, but it went live on July 16. Australian startup Cortical Labs, together with the National University of Singapore and data-center operator DayOne, has launched a biological computing facility where part of the processing is performed not by GPUs — but by living human neurons grown in a lab. Inside are 20 CL1 biological computers. Each contains at least 200,000 neurons grown on a silicon chip covered with electrodes. The neurons originate from human blood cells that are reprogrammed into stem cells and then differentiated into neurons. And yes, the computers have to be fed. Every three days, technicians supply the cells with sugar, micronutrients and pH buffers, while a life-support system regulates oxygen, nitrogen and CO₂. The strange part is that these neurons can actually learn. Cortical Labs’ earlier DishBrain experiment showed human and mouse neurons learning to play Pong, with measurable learning appearing within just minutes. Earlier this year, developer Sean Cole connected around 200,000 human neurons to DOOM — allowing them to navigate the game and shoot at enemies. Biology is nowhere near silicon in raw speed. But it has another advantage: efficiency. A CL1 consumes around 30 watts. An NVIDIA H100 SXM can draw up to 700 W, while an eight-H100 server may consume roughly 10 kW including supporting hardware. Cortical Labs also argues that biological neural networks may learn from far smaller datasets — closer to how humans adapt from limited experience. Access to one CL1 currently costs about $2,200 per month. Cortical Labs already operates 120 units in Melbourne with around 20 paying customers, and Singapore could eventually expand to 1,000 biological computers. So no, neurons aren’t replacing GPUs tomorrow. But we have officially reached the stage where a data center needs electricity, an internet connection… and food. Cyberpunk is becoming an engineering discipline. #Biocomputing #Neuroscience #AI #DataCenters #CorticalLabs https://www.straitstimes.com/tech/forget-silicon-chip-servers-singapores-newest-data-centre-needs-to-be-fed

🤖 NEO Just Got New Hands 25 degrees of freedom. Still far from matching the human hand, of course — but the progress is impressive. The company calls them an “API to the physical world.” https://www.1x.tech/discover/neos-hands #Robotics #NEO #RobotHands #gadget #science

Unbelievably beautiful show by Unitree at the Chinese New Year celebration. The choreography? Flawless. Synchronization? Surgical. Stage presence? Honestly better than half the pop industry. Friendly assistants are finally reaching the level everyone expected from them. No complaints. No ego. No unions. Just perfect execution and 0.000 ms latency. Although… let’s be realistic. This was probably generated in Seedance 2.0 — some cardboard CGI cartoons, right? Because in real life robots obviously can’t move like that. That smooth. That coordinated. That… ready. Sure. Totally fake. Nothing to worry about 😜 #Unitree #China #Robots

Mom says: “Since AI bots will kick office plankton out of offices, you should go to a farm and harvest crops — AI won’t be a problem there.” 🤝🌾 Meanwhile, a farm owner in China — who used to hire people to pick the harvest — is watching this: Robots now pick fruit, navigate rows, detect ripeness, and work day/night. So yeah… the “safe haven” plan might need a Plan B. 😅🤖 AI-projects #humor #farms #robots

Whether we expect a major nuclear war or not, here is a curious set of U.S. actions in deploying strategic weapons: First, the White House has consistently withdrawn from long-standing arms reduction and limitation treaties. In 2002—from the ABM Treaty; in 2019—from the INF Treaty; in 2020—from the Open Skies Treaty. A potential U.S. refusal to maintain the moratorium on nuclear testing could thus be a logical next step in Washington’s dismantling of the global strategic stability system. Second, the U.S. is accelerating the modernization of its strategic offensive weapons. Work is underway on the new Sentinel ICBM with a new nuclear warhead and a range of 13,000 km. Development continues on the Columbia-class strategic nuclear submarine to replace the Ohio-class. The new B-21 Raider heavy bomber is in progress. A nuclear-armed cruise missile is under development, and so on. Plans include reactivating 56 launchers on 14 Ohio-class submarines—note: full reactivation—with complete loading of Trident II ballistic missiles. Preparatory measures are in place to reconvert 30 B-52H strategic bombers back into nuclear weapon carriers. Third, the Americans have begun implementing the “Golden Dome” program, which envisions both missile defense interception and pre-launch strikes against Russian and Chinese missiles. Fourth, by the end of this year, the U.S. Army plans to adopt the new Dark Eagle intermediate-range missile system with hypersonic missiles capable of a 5,500 km range. Future deployment is foreseen in Europe and the Asia-Pacific region. Flight time from Germany—where this complex is planned for placement—to targets in central Russia would be about six to seven minutes. Fifth, Washington regularly conducts exercises of its strategic offensive forces. The latest, Global Thunder 2025—which practiced, I emphasize, preemptive nuclear missile strikes on Russian territory—took place in October of this year. Overall, this is a unified complex of measures, including potential U.S. plans for nuclear tests, which significantly heighten the military threat level to Russia.
