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
Show HN: Armin – Modern Anki alternative with prerrequisite graphs
okay, so a bit of context. back when i was studying at college, i was trying to optimize my learning process as much as possible, and i ended up discovering Anki and spaced-repetition as a concept. i ended up using Anki for quite a while and it did help me. i loved the concept... but i didn't like the app. it had me conflicted. on one hand, it allowed me to properly review the content from my classes (among other stuff), but on the other it had way too many quirks and complicated ways of ha
Ask HN: Still Getting [Dead] Posts
Unfortunatelly, after quite some time, I'm still getting my posts flagged -- it's a technical blog post on my company's website, flagged as DoA.<p>Still unsure what am I doing wrong, I think the topic is relevant to HN and it's definitely not an ad - the system is a toy experiment to understand how the k8s control-plane works...

Show HN: Headwig - Run and test parallel AI agents without Git worktrees
Hey HN! I am Harsh, been developing software for quite sometime now. Since agents came into my local SD workflow I had been facing a bottleneck. Event though agents are great in working parallelly, testing their changes and iterating is a pain. (Brain, storage & memory overhead)We all use Git worktrees to code in parallel. But how do we test those changes? Still linearly. Or patched up multi-environment setup.And what if you have multiple microservices in an application? How do you test diff
Ask HN: How do you market your consumer product
I've been building and selling B2B for most of my career and it seems things have changed quite a bit when it comes to launching a consumer product online.Observations:1. Product Hunt is dead. Everybody is selling something, and you get spammed instantly.2. Show HN seems unbalanced. I've tried a few threads and the only traction I saw was getting emails (10-20 per day) from other startups, including YC startups, all following the same template which is incredible "Hey saw your Sho
Show HN: Apron Chat Protocol
Hi HN friends - I've been obsessed with chat protocols for ages - one previous project is ssh-chat (https://ssh.chat/)I come bringing a new kind of chat protocol that I've been working on since I spent quite a lot of time exploring the 14 other competing standards we've come up with in the past few decades.The protocol details are here: https://apron.chatI'm hoping that Apron will better reflect our needs beyond 2026, which I expect will move more and
Distributed Ray Tracer
Hey HN, I'm Julius, I'm a backend engineer at Hatchet and created this demo to show off some of Hatchet's new features, primarily durable streams and serverless endpoints. Those, however, are just background details that made this significantly easier to scale. By distributing the rendering across many different nodes, orchestrated using Hatchet, it makes it possible to render quite high fidelity scenes fairly quickly. All of this would be possible on a single machine, but would b
Chinese scientists cool atoms to near absolute zero in record-breaking experiment
Scientists have cooled atoms to the coldest temperature ever recorded, using a laser trap aboard China's Tiangong space station.Tiangong included an experiment in which atoms were cooled to 10 picokelvins, which is barely above absolute zero, the coldest theoretical temperature possible in physics. Absolute zero is minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius) and the threshold at which all particles in an object are believed to stop moving.Scientists
Massive atlas of brain region linked to a host of diseases is the most detailed yet

Reduced Longitudinal Coupling Boosts Efficiency in Two-Qubit Quantum Otto Heat Engine
Reducing longitudinal coupling markedly improves maximum work output and peak efficiency in a two-qubit anisotropic Heisenberg XYZ quantum Otto engine.
Environmental Memory Revives Two-Qubit Entanglement in Stochastic Optical Cavity Dynamics
Analytical modeling of a two-qubit Jaynes–Cummings system reveals that non-Markovian coupling noise and decoherence-free subspaces can revive and indefinitely preserve quantum entanglement.
This AI Learned Language From the Recordings of a Baby’s First 1,000 Days
AI models that learn like kids could reveal the secrets of our early years and inspire more efficient machine minds. Babies are linguistic geniuses. Born into a noisy, chaotic world, they gradually distill incomprehensible sounds into words. Within two years, they can recognize thousands of words, follow complex sentences, and shout out their needs.How they achieve this feat has long puzzled scientists. Babies develop language skills from an intimate world—the voices of their parents, chatter fr
Imperfections reveal unexpected links between light and atomic vibrations in ultrathin boron nitride
First, one person stands up, followed by their neighbors, one after another, until a wave sweeps through the stadium. Atoms within a material move in a similar way: rather than remaining completely still in their positions, they vibrate together around their respective positions. In physics, these collective lattice vibrations are known as "phonons." Some of them can interact with light and change its energy in the process.
