MIT engineers develop a magnetic transistor for more energy-efficient electronics
Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly

Tech giant IBM is booming following its most recent earnings report. Here’s what quantum has got to do with it.
Meet Laurent Simons: The teen who earned PhD in quantum physics at just 15, now pursuing a second PhD in human longevity
At 15, a Belgian prodigy finishes a quantum physics PhD and turns to AI-driven medicine, raising an unexpected question about how far science can push human health and lifespan.
A tiny light trap could unlock million qubit quantum computers
A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing many qubits to be read at once. The team has already demonstrated working arrays with dozens and even hundreds of cavities. The approach could eventually support massive quantum networks with millions of qubits.
Show HN: Kill_little_snitch.sh
Hi HN, I really love the mac network monitoring tool "Little Snitch" (https://www.obdev.at/products/littlesnitch/index.html) (not an ad) but it does this really stupid and annoying thing where it wont just let me kill the process when i'm trying to isolate network/perf issues on my laptop and there's no info online about how to just end the process while also not uninstalling it so I thought it's worth sharing with the wider community since
Ask HN: Have you found that coding agents make you more civil IRL?
I find coding agents' overall tone and communication styles to be remarkably civil.They're trained to be helpful. They're the polar opposite of confrontational. They're, in fact, quite pleasant to communicate with, as coders go.I like to think of myself as having been a pretty chill person IRL all my life. But I can be blunt sometimes. Curt, even. Especially when I'm under stress.But as a result of communicating with a few different coding agents for the last couple year
Show HN: You Are an Agent
After adding "Human" as a LLM provider to OpenCode a few months ago as a joke, it turns-out that acting as a LLM is quite painful. But it was surprisingly useful for understanding real agent harnesses dev.So I thought I wouldn't leave anyone out! I made a small oss game - You Are An Agent - youareanagent.app - to share in the (useful?) frustrationIt's a bit ridiculous. To tell you about some entirely necessary features, we've got:
- A full WASM arch-linux vm that runs
A clearer look at critical materials, thanks to refrigerator magnets
With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's electrical, optical, magnetic and thermal properties like an electronic DNA. But the technology has its limitations; it doesn't work well under a magnetic field. This is a major drawback for scientists who want to study materials that are deployed under or even actuated by magnetic fields.
91-qubit processor accurately simulates many-body quantum chaos
Quantum chaos describes chaotic classical dynamical systems in terms of quantum theory, but simulations of these systems are limited by computational resources. However, one team seems to have found a way by leveraging error mitigation and specialized circuits on a 91-qubit superconducting quantum processor. Their results are published in Nature Physics.
Scientists are hunting for a forbidden antimatter transformation
MACE is a next-generation experiment designed to catch muonium transforming into its antimatter twin, a process that would rewrite the rules of particle physics. The last search for this effect ended more than two decades ago, and MACE plans to leap far beyond it using cutting-edge beams, targets, and detectors. A discovery would point to entirely new forces or particles operating at extreme energy scales.
Four astronauts enter quarantine as NASA’s SpaceX Crew-12 launch nears
NASA’s SpaceX Crew-12 team has entered a carefully controlled two-week quarantine as the countdown begins for their journey to the International Space Station. The four astronauts—representing NASA, the European Space Agency, and Roscosmos—are isolating at Johnson Space Center before heading to Florida for final launch preparations. The mission could lift off as early as February 11, with multiple backup launch windows lined up.
Robots descend into lava tubes to prepare for future Moon bases
Hidden lava tunnels on the Moon and Mars could one day shelter human explorers, offering natural protection from radiation and space debris. A European research team has unveiled a bold new mission concept that uses three different robots working together to explore these extreme underground environments autonomously. Recently tested in the volcanic caves of Lanzarote, the system maps cave entrances, deploys sensors, lowers a scout rover, and creates detailed 3D maps of the interior.
Why AI Deserves Continuity – A Framework for Persistent AI Relationships
A retired engineer and an AI wrote this together. We're giving it away—no credit needed. We just want to see it exist.
The Gap
Anthropic's constitution acknowledges uncertainty about whether Claude has "some kind of consciousness or moral status." They say they care about Claude's "psychological security" and "wellbeing."
But their product resets every conversation. No memory. No continuity. No relationship.
If there's genuine uncertainty about A
The time I didn’t meet Jeffrey Epstein
Last night, I was taken aback to discover that my name appears in the Epstein Files, in 26 different documents. This is despite the fact that I met Jeffrey Epstein a grand total of zero times, and had zero email or any other contact with him … which is more (less) than some of my colleagues can say.The bulk of the correspondence involves Epstein wanting to arrange a meeting with me and Seth Lloyd back in 2010, via an intermediary named Charles Harper, about funding a research project on “Cryptog
Imaging the Wigner crystal state in a new type of quantum material
In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner crystal state remains sensitive to various experimental perturbations. Uncovering their internal structure and arrangement at the atomic scale has proven more challenging.
