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

Quantum battery designers cannot have both high power and stable output, physics proves

Quantum battery research proved an inescapable trade-off: the more quantum entanglement a design uses to boost charging power ...

Show HN: Talktome - let your AI Agent call you

I built TalkToMe, an open-source macOS app that lets an agent call you from its current session. You answer, talk, and hear its replies. The agent keeps its tools, files, and history.It works with Codex (Tested extensively, quite smooth), Claude Code...

Show HN: LogPhase – See a PR's blast radius as impacted user journeys

Hi all,I've been working on this app for a few months now, and I think it's at a stage where I can share it with everyone.I built this app because AI-assisted coding is here to stay. With the right harness, AI can handle many things that we...

Show HN: Rename.Tools – Open-source bulk file renaming in the browser

Hi HN, I built Rename.Tools after needing to rename a large batch of images. This is something I only do occasionally, so I couldn’t justify buying dedicated software for it. The free tools I tried didn’t quite fit my needs either. When I discovered...

Rotating light pattern reveals laser frequency in a single image

An international team of physicists has developed a new method for determining the precise color of laser light using an image that rotates as the laser's frequency shifts.

New statistical method can flag hidden anomalies in scientific datasets

A research team at the University of Vienna, led by pharmaceutical chemist Johannes Kirchmair, has developed a statistical method to identify hidden anomalies in scientific datasets. The method can be applied automatically to large datasets, making i...

Show HN: Error in official Swiss weather forecasts, recorded since September '25

Hi. In summer 2025, I got a bit disappointed that many days ended up hotter than they were forecast, and decided to quantify this to see how "bad" is it. So I started recording.I took forecasts for Bern and Zürich at the end of the day (~10...

The ice blasting from Saturn's moon Enceladus is stranger than scientists realized

Enceladus may naturally separate and concentrate chemicals from its hidden ocean as droplets slowly freeze and shatter on their way into space. The process could explain Cassini’s puzzling ice-grain chemistry while giving future spacecraft a powerful...
