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

More Space Junk Is Plummeting to Earth. Earthquake Sensors Can Track It by the Sonic Booms.

Scientists are co-opting seismic sensors to detect space debris streaking through the atmosphere at hypersonic speeds. In the early morning of April 2, 2024, the sky over southern California lit up with flashes of blazing light. Residents were bewildered. Were they missiles? A crashing plane? The unusual activity confused even experts—until they realized it was a disposable part of China’s Shenzhou-15 spacecraft burning up in the atmosphere as it returned to Earth.Scientists knew the event was o

Show HN: Design is Code – UML to TDD tests that constrain AI code generation

Two root causes make AI code generation unreliable:Natural language isn't a contract. It's ambiguous by nature. Same prompt, different code, every time. There's no determinism.Cost is asymmetric. AI generates at zero cost with zero responsibility. You review at high cost with full responsibility.These compound. Ambiguous input produces unpredictable output. Unpredictable output demands expensive review. And if no one designed the code, no one can defend the architecture, no one ca

Ask HN: Did AI tools measurably increase productivity of your engineering teams?

I lead a small engineering team and while basically everyone is enthusiastically using claude code and the like there is not really an obvious change of <i>output</i>.<p>Of course this has always been hard to quantify but the number of tickets completed every week is roughly steady. This does not seem to match self reported efficiency gains.<p>How has this been going for you?

Show HN: PiQrypt – Cryptographic audit trail for AI agents (Ed25519, Dilithium3)

AI agents are making decisions that affect money, infrastructure, and users — but most systems rely on editable logs.I built PiQrypt to explore whether an AI agent can have a cryptographically verifiable decision history.Each event is: - Ed25519 signed - SHA-256 hash chained - Fork-detectable - Optionally RFC 3161 timestamped - Optional post-quantum (Dilithium3 &#x2F; ML-DSA-65)The goal isn&#x27;t blockchain or consensus — it&#x27;s agent identity continuity and tamper-evident history.MIT licens

Show HN: GDBS – Browser geometric physics engine replacing HPC cluster workloads

I built a physics computation platform that replaces brute-force numerical PDE solvers with analytic geometry evaluated in a 13D coordinate space. Instead of discretizing onto million-cell meshes and iterating to convergence on a supercomputer, GDBS maps physical systems into geometric positions where observables become exact coordinates. Evaluation is O(N) instead of O(N³), so what takes HPC clusters hours runs in &lt;100ms in WebAssembly in the browser.7 physics domains: plasma&#x2F;fusion, ma

Show HN: Localvoxtral – Local real-time dictation on macOS with streaming STT

I built a native macOS menu bar app for real-time dictation that can run fully on-device.Most dictation tools, even local ones, use Whisper or similar offline models: you record, then wait for the transcript. Localvoxtral uses Mistral&#x27;s Voxtral Realtime, one of the first open-source speech models with a natively streaming architecture. Words appear as you speak, not after you stop. It feels closer to someone typing along as you talk.Press a shortcut, speak, and text gets typed directly into

Quantum effect could power the next generation of battery-free devices

A new study has revealed how tiny imperfections and vibrations inside a promising quantum material could be used to control an unusual quantum effect, opening new possibilities for smaller, faster, and more efficient energy-harvesting devices.

Physicists watch light drift in quantized steps for the first time

In physics, the classical "Hall effect," discovered in the late 19th century, describes how a transverse voltage is generated when an electric current is exposed to a perpendicular magnetic field. Simply put, the magnetic field causes the electrons, which are negatively charged, to drift sideways, creating a negative charge on one edge of the conducting strip and a positive charge on the opposite side.

AI develops easily understandable solutions for unusual experiments in quantum physics

Researchers at the University of Tuebingen, working with an international team, have developed an artificial intelligence that designs entirely new, sometimes unusual, experiments in quantum physics and presents them in a way that is easily understandable for researchers. This includes experimental setups that humans might never have considered. The new AI doesn't just create a single design proposal; instead, it writes computer code that generates a whole series of physical experiments, that is

50 year quest ends with creation of silicon aromatic once thought impossible

After nearly 50 years of failed attempts and scientific speculation, chemists at Saarland University have achieved what many thought might be impossible: creating a long-sought silicon-based aromatic molecule. By replacing carbon atoms in a famously stable ring-shaped compound with silicon, the team synthesized pentasilacyclopentadienide — a breakthrough published in Science.

Clearing the path for turbulence-free quantum communication

A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending quantum information through air. Their paper, "All-optical turbulence mitigation for free-space quantum key distribution using stimulated parametric down-conversion," appears in the journal Optica.

Something strange is happening in the Milky Way’s magnetic field

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, revealing surprising twists in how it flows through our galaxy.

Can solar storms trigger earthquakes? Scientists propose surprising link

Scientists have proposed a surprising connection between solar flares and earthquakes. When solar activity disturbs the ionosphere, it may generate electric fields that penetrate fragile fracture zones in Earth’s crust. If a fault is already critically stressed, this extra electrostatic pressure could help trigger a quake. The idea doesn’t claim direct causation, but it offers a fresh way to think about how space weather and seismic events might interact.
