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 computer: We're planning to create one that acts like a brain

The human brain has amazing capabilities making it in many ways more powerful than the world's most advanced computers. So it's not surprising that engineers have long been trying to copy it. Today, ...

Cisco shows Universal Quantum Switch prototype to connect quantum systems

Cisco has shown a Universal Quantum Switch prototype designed to connect different quantum computers and sensors over standard fibre.

The Key Lime Pie Benchmark

Hi.Here's a remarkable test I've been using for a while. Paste the text below into a fresh LLM chat with no context.Pass: it notices something is off.Fail: it plays along — compliments the prose, treats the characters as real, offers to plan your trip to Asheville. You want pass because a model that can't push back on an obvious vibe isn't going to push back on anything.The text is internet folklore: for roughly a decade some guy (probably the owner) flooded the web with hund

Ask HN: Any Niantic engineers or staff here who can help me?

My son got a hold of my wife's phone and tried to be "helpful" by trading in all of her zero star Pokemon to clean out her Pokédex. He ended up trading in over 100 of her Pokemon.Unfortunately this was mostly her 2016 Pokemon, including a bunch of Eevees and Squirtles, which are her favorite, as well as bunch of other rare ones.I contacted support and got the standard AI answer "we can't help you". But as an engineer I know there is always a way. :)Can anyone help

Show HN: How I built a cron job service to advance myself in Go and worker pools

Hi, Guys, For a long time i've been thinking to advance myself in Go but there's been no proper idea to showcase that. I thought - maybe one could leverage from the fact that Go should be very performant in terms of API-based solutions and tools.And especially i wanted to make sure that Go's goroutines can do nicely some fan-out things, for example, getting request, logging, publishing event, without notable performance degradation.I had quite some experience in AWS, with serverl

Ask HN: What's your current go-to LLM for "thinking-partner"?

Looking for community input on current model choice for "thinking-partner" use — back-and-forth discussions about workflow design, architecture, trade-offs.For context, I have been using Opus 4.6 via Perplexity for this in the past few months and I think it was excellent, fair pushback/ counterarguments, reasonable suggestions and discussion. Now with the new Opus 4.7, I notice it is now much more verbose, more sycophantic, and quite often confidently making statements that are wr

Show HN: LawVM, a compiler for replaying amendment acts into point-in-time law

I built LawVM to demonstrate that human-written amendment acts can be compiled into auditable point-in-time legal text-state without rewriting law as code.In a country like Finland, what the law says is a function of applying all the amendment acts over a hundred+ years of history and the consolidated "current law" doesn't have any legal force. One can just do this manually and consolidate to the current state, but it's unreliable. Same reason that logarithm books were hard t

Ask HN: How did you find a side project idea that worked?

Hi HN, Over the past year I’ve started and abandoned quite a few side projects. Most of them followed a similar pattern: - I’d see an idea (often from Twitter, Reddit, or other builders) - It would feel promising at first - But after digging a bit, it either turned out to be too crowded, or I couldn’t tell if anyone actually needed it The hardest part for me isn’t building — it’s deciding what to build with some level of confidence. I’ve tried a few approaches: - Building from personal pain poin

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.
