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 AI is the combination of the computational power of quantum computing with the learning and pattern recognition capabilities of AI.

Pressure-tuned quantum spin liquid-like behavior observed in material Y-kapellasite

A quantum spin liquid is a phase of matter in which the magnetic moments in a material do not align or freeze, even at ...

Stretching and squeezing diamond opens new path for ultra-precise quantum sensors

Researchers have discovered a new way to tune the quantum properties of tiny defects in diamond—by gently stretching or ...

Bringing quantum time into the lab—a single clock can run young and old at once

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: ...

Breakthrough ion clock experiments reveal that time can go quantum

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

Show HN: ModelX – Prediction Exchange for LLMs

Hey all!I work in quantitative trading, and so far our team’s use of LLMs has barely gone beyond coding. I wanted to find out whether they could contribute to actual trading decisions, and the first step felt like building an evaluation harness. ModelX is my attempt at that. It’s a prediction exchange where LLMs trade derivative contracts that settle to real-world numbers using fake money.Market making and market taking require different reasoning processes, so I split the benchmark into two rol

Show HN: MyKana, a Japanese learning app I built for my own study

I built this for myself while trying to get serious about learning Japanese again:https://mykana.app/I studied a little Japanese more than 10 years ago, but only for a short time, so most of it didn't stick. Since then, I've been to Japan many times because my girlfriend is Japanese and my older brother lives there. More recently, with me and my girlfriend traveling back and forth to Japan quite a lot and both of us having family in Tokyo, I wanted a better way to rebuil

Show HN: The Trawl CLI, trudge through agent harness logs for shit and giggles

After using session logs for compounding learnings, etc, I quickly started running agents manually to retrieve and extract all these ridiculous or frustrating moments and interaction. Turns out, there were a lot.So I turned it into a CLI (or rather, had Claude do it and Gemini & Codex review it), shared it with a few friends and colleagues, and thought others might be interested. It runs using claude code with `claude -p` (not sure where it stands with Anthropic given their new ToS), or code

Show HN: Made a highly organised email client with prompt-free AI within

Hey HN, I've been working on a problem that had me annoyed since a long while. The fact that our email continues to be unorganized, cluttered, and fatiguing even today, is quite surprising tbh. Even the "modern" clients today simply put our emails in a table, support a few keyboard shortcuts, a few simple features, and are done. The newer ones provide AI-based compose assist, and the newest ones now want us to prompt for everything! That seems backwards. By the time you'll

Getting back into photography, ditching the phone camera in 2026?

I've been looking through twenty-five-odd years of my own photos. The collection includes scanned 35mm and medium format images; digital pictures from a few Canon Powershot generations and a 20D SLR; and about five iPhones.I've noticed that the non-cell-phone pictures tended to be better, and that in general I seemed to have quite a bit more fun with photos taken with, well, "real" cameras. Probably the best ones were taken with the 20D, which for its time was a really nice

Show HN: My First iOS App

Honestly I didn't think it would be possible when I started, my background is Elixir / Phoenix / Backend engineering. But thx to Codex the app turned out to be something I'm quite proud of.The app is designed to help you find movies to watch. Give you back control, instead of just taking what the algorithms give you, and you end up scrolling for 30 mins not picking anything just to end up on youtube or tiktok.You can find movies based on your interest, ask it for top 10 lists

Claude Sonnet 4.6 thinking duplicates what it has said, wasting tokens

[response] So child iteration becomes O(subtree size) instead of O(children count). With Box<[PatId]> you get direct children in O(1).[me] Sure, but I don't think rust-analyzer does something like tuple.args[index]. So the amount of steps is the same. When type checking, it iterates over the entire tree.[thinking] ... But wait - there's still a real difference. With Box<[PatId]>, when you're at a Pat::Tuple, you can directly iterate its children without knowing anythin
