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 Entanglement and W-State Dynamics

Quantum entanglement lies at the heart of quantum mechanics, describing non-classical correlations that arise when particles share a joint quantum state. While bipartite entanglement between two ...

Is it worth to study HPC and GPU programming?

I am going to do my Msc in Computer Science and I'll have to pick a specialization between Parallel Computing, Scientific Computing, Quantum Computing, Data Science, or Theoretical CS. Is HPC something thats worth taking courses in or is it something you'd learn later on when you're a senior engineer?

Roadmap charts three paths to room-temperature quantum materials for cooler computing

Imagine a laptop that never gets hot, a phone that holds its charge for days, or a computer memory chip designed to permanently retain data, even when the power goes out. This is the possibility sitting inside a remarkable family of materials that a team of researchers from the University of Ottawa and the Massachusetts Institute of Technology (MIT) has spent years trying to understand, and they just published a comprehensive roadmap of the field to date in the journal Newton.

Ask HN: What LLM models are you using and why?

Hello, HN!I'm wondering what y'all are using for your daily driver these days and why?I've found myself using GPT-5.5 more than Opus 4.7 for work; which, has been a pretty big reversal. Previously, I was using Opus 4.6 for everything, and GPT-5.4 was only ever in the picture to provide a second opinion (with Grok a distant 3rd only when I wanted to throw some "chaos" into the mix). The reason I've personally pivoted, is I've found GPT-5.5 to be a bit more consi

First-ever direct image of the cosmic web reveals the Universe’s hidden highways

Astronomers have revealed the sharpest image ever captured of a filament in the cosmic web — the enormous hidden structure connecting galaxies across the Universe. The glowing strand stretches 3 million light-years and links two galaxies from nearly 12 billion years ago. By observing this faint intergalactic gas directly for the first time in such detail, scientists gained new insight into how galaxies are fueled and formed.

New Algae Robots Swarm Like Locusts at the Flick of a Switch

Self-assembling swarms of microrobots could someday deliver drugs and pull toxins from water. For most of us, a locust swarm sounds like an utter nightmare. For roboticists, it’s inspiration.Nature abounds with creatures that cooperate with a “hive mind.” From bees gathering pollen to schools of sardines grouping to avoid predators, individuals seamlessly move together in ever-changing configurations. Roboticists inspired by these dynamics have designed microrobots—often no more than the width o
