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

US Solar Surged 35% in 2025, Overtaking Hydro for the First Time

Fossil fuels still dominate the energy mix. But growth in renewables offset nearly 75% of new power demand. Booming energy demand is driving a scramble to set up new generating capacity, and one technology is proving to be the clear winner. Newly released federal data shows that solar power grew by more than 35 percent year-over-year in 2025, outpacing all other forms of generation.After decades of relatively flat electricity use, US power demand is rising again. A new report from the US Energy

Show HN: Cifer, zero-key custody using threshold cryptography

I built CIFER, a distributed encryption + access-control system designed so that no component ever holds a complete decryption key at rest.Core idea: each “secret” (per user or per dataset) has its own independent post-quantum keypair. There is no master key.Architecture summary:Control plane: verifiable ownership, delegation, revocation, and append-only audit records (tamper-evident authorization history)Custody plane: 5 custody nodes running in TEEs, each storing 1 key fragmentOrchestration: v

Matching vibrations is all it takes to shut down superconductivity in a nearby crystal

The world is never really at rest. Even in a vacuum near ultracold temperatures where all classical motion should come to a halt, you'll find quantum fluctuations. In thin, two-dimensional materials, these include random vibrations that can alter electromagnetic fields, a feature that theorists have posited could be quite useful for modifying materials.

Rydberg atoms detect clear signals from a handheld radio

For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from an ordinary handheld radio. Through a careful approach to demodulating the incoming signals, Noah Schlossberger and colleagues at the National Institute of Standards and Technology (NIST) were able to recover audio encoded in multiple public radio channels, with promising implications for everyday uses in consumer electronics. The research has been published in Physical Re

Researchers unlock hidden dimensions inside a single photon

Researchers have discovered new ways to shape quantum light, creating high-dimensional states that can carry much more information per photon. Using advanced tools like on-chip photonics and ultrafast light structuring, they’re pushing quantum communication and imaging into exciting new territory. Although long-distance transmission remains tricky, innovative approaches—such as topological quantum states—could make these fragile signals far more resilient. The momentum suggests quantum optics is

Apollo rocks reveal the Moon had brief bursts of super-strong magnetism

Scientists at the University of Oxford have finally settled a decades-long mystery about the Moon’s magnetic field — and it turns out both sides were right. By reanalyzing Apollo mission rocks, they discovered that the Moon did occasionally generate an incredibly powerful magnetic field, even stronger than Earth’s — but only for fleeting bursts lasting thousands of years or less. Most of the time, the Moon’s magnetic field was weak.

Energy loss triggers quantum thermal Hall-like effect at macroscopic scale

In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are essentially quantized energy states that form when charged particles move in a magnetic field.
