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

New “optical tornado” technology could transform quantum communication

Scientists have created tiny “optical tornadoes” — swirling beams of light that twist like miniature whirlwinds — using a surprisingly simple setup based on liquid crystals. Instead of relying on complex nanotechnology, the team used self-organizing structures called torons to trap and manipulate light, causing it to spiral and rotate in intricate ways. Even more impressively, they achieved this effect in light’s most stable, lowest-energy state, making it far easier to generate laser-like beams

This exotic particle could finally explain why matter has mass

A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped inside a nucleus. This exotic state may reveal how mass is generated, suggesting that particles can weigh less when surrounded by dense nuclear matter. The findings support long-standing theories about how the vacuum of space influences mass.

Gravitational waves may have created dark matter in the early universe

In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the cosmos—they could have helped create dark matter itself. New research suggests that faint, ancient gravitational waves might have transformed into particles that eventually became the invisible substance shaping galaxies today.

Show HN: RoboAPI – A unified REST API for robots, like Stripe but for hardware

Every robot manufacturer ships a different SDK and a different protocol. A Boston Dynamics Spot speaks nothing like a Universal Robots arm. Every team building on top of robots rewrites the same integration layer from scratch. This is a massive tax on the industry.RoboAPI is a unified API layer that abstracts all of that into one clean developer experience. One SDK, one API key, any robot — simulated or real hardware.You can connect a simulated robot and read live telemetry in under 5 minutes:

Ask HN: How are you evaluating AI apps and CLI?

I'm sure many of you work for companies where various AI tools are being made available and IT departments asking for feedback on those tools. The IT departments are allocating in some cases unlimited budget in the hopes that something comes out as a winner and sticks out eventually...For example the models from Anthropic, OpenAI, Google etc. can be accessed via: - IDE integration, e.g. VS Code, JetBrains etc. - Dedicated apps and CLIs, e.g. Codex, Claude, Copilot CLI etc.It's already

A Humanoid Robot Beat the Human World Record for a Half Marathon

A year after most robots failed to finish the Beijing race, nearly half the field autonomously ran a course of slopes, narrow passages, and 20 turns. Humanoid robots are Silicon Valley’s latest obsession, but real-world performance has lagged the hype. That may be starting to change, however, after a robot beat the human record for a half marathon by nearly seven minutes in Beijing.While tech companies around the world are piling into humanoid robots, China has made it a national priority. The g

NASA scientist says a "fifth force" may be hiding in our solar system

Scientists are grappling with a cosmic mystery: why does the Universe behave differently on massive scales compared to our own solar system? While distant galaxies reveal clear signs of something bending the rules of gravity—often attributed to dark energy or a hidden “fifth force”—everything nearby seems to follow Einstein’s playbook perfectly.

Astronomers may have found a strange new kind of cosmic explosion

A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar cataclysm. After detecting ripples in space-time, scientists spotted a fast-fading red glow that initially looked like a rare kilonova—the kind of collision that forges gold and uranium. But just days later, the signal shifted, behaving more like a supernova, leaving researchers puzzled. Now, some think they may have witnessed something never seen before: a “superkilonova.”
