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

Mirror-positioning method could make quantum gravity tests possible

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where a particle does not have a single definite value of position or momentum until it is measured. A major open question is whether gravity, one of the fundamental forces, also follows the quantum rule. One way to examine this is through gravity-induced entanglement, in which two objects that interact only via gravity become quantum mechanically linked.

Using atomic nuclei could allow scientists to read time more precisely than ever

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions.

Quantum simulations tackle photon polarization flip, but today's hardware falls short

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has been a cornerstone of the standard model, withstanding the scrutiny of countless experiments and agreeing with observations down to the smallest known precisions. Yet, some high-intensity scales of QED remain unexplored, prompting some to wonder if quantum computers could deal with these scales' inherent complexity.

Harnessing the fundamental rules of the universe

Tue, 14 Apr 2026 12:00:00 +0000Every April 14, the global quantum community celebrates World Quantum Day. It’s a day that resonates strongly at Waterloo — Canada’s densest cluster of quantum talent, researchers, students and industry partners. Here, they work in close proximity, using the universe’s fundamental rules of quantum science to create new technologies, shaping Waterloo’s Quantum Valley. Tags: Community updates

How Quantum Mechanics Went From Baffling Theory to Revolutionizing Modern Technology

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Ask HN: What's your experience with PoW captchas against form spam?

Hey folks,I'm building an Open Source email newsletter tool and one of the challenges we have is form spam: As soon as a signup form goes live somewhere, bots will try to sign up. This is possibly an attempt to overwhelm the inbox of people whose accounts have been compromised. But it's also bad for the people who run the newsletter as these ultimately unwanted emails reduce their sender reputation.There was recently a discussion here on HN about this topic [1]. The post author ended u

Ask HN: On autistic spectrum, best way to live?

I've been highly logical and obsessive with reading since early childhood, and I got into programming pretty early and built Flash animation since kindergarten. I've always had issues with my peers and teachers, I got bullied quite often, and it was a source of emotional distress. I felt the constant need to work on things that intrigues me, and I'd read books like encyclopedia, I didn't know that then, but I now suspect myself to be on the spectrum. I believe many in the HN

Show HN: Revdiff – TUI diff reviewer with inline annotations for AI agents

I built a terminal diff viewer for a workflow I couldn't do comfortably with existing tools: reviewing AI-generated code changes without leaving the terminal session where the agent runs, annotating what needs to change, and feeding those annotations straight back to the agent. Plenty of diff viewers exist, and some can even feed notes back to an agent, but none of them fit that flow for me - they pulled me out of the terminal into a separate app, or the round-trip back to the agent was clu

Show HN: Specsight – Living product specs generated from your codebase

Heyy HN, I'm OlaI'm an engineer myself, and everywhere I've worked there was a similar dynamic: someone from the non-technical side of the team (PM, CS, stakeholders) needs to understand what changed recently or how something works today. They rely on stale Confluence pages or ping engineers in Slack and wait. engineers get interrupted daily answering "how does this actually work". it's a mess that gets worse as the team growsor when you join a new company and try t

Show HN: Equirect – a Rust VR video player

This is almost entirely created by Claude, not me. I know some people aren't into that. I was one of them 3 months ago. Since the beginning of the year I finally started getting more serious about trying out AI. The company I work for also had an AI week with lots of training. All I can say is I'm pretty blown away. My entire life feels like it changed over the last month from someone who mostly writes code to mostly someone that prompts AI to write code. And just for a tiny bit of con

Scientists just recreated a rare cosmic reaction never seen before

A breakthrough experiment has shed new light on one of astrophysics’ biggest mysteries: the origin of rare proton-rich elements. For the first time, scientists directly measured a key reaction that creates selenium-74 using a rare isotope beam. The results sharpen models of how these elements form in supernova explosions, cutting uncertainty in half. But the findings also reveal gaps in current theories, hinting that the story isn’t complete yet.

Quantum systems can remember and forget at the same time, scientists discover

Quantum systems can secretly “remember” their past—even when they appear not to. Scientists found that whether a system shows memory depends on how you look at it: through its evolving state or its measurable properties. Each perspective uncovers different kinds of memory, meaning a system can seem memoryless and memory-filled at the same time. This discovery could change how researchers design and control quantum technologies.

Scientists Grow Electronics Inside the Brains of Living Mice

The technology harnesses the brain’s own blood chemistry to assemble soft, light-controlled electrodes around neurons. A single shot transforms the mice’s brains into biomanufacturing machines. Blood proteins churn the injected chemicals into a soft, flexible electrode mesh that seamlessly wraps around delicate neurons. Pulses of light aimed at the mesh quiet hyperactive cells. All the while, the mice go about their merry ways, with no inkling they’ve been turned into cyborgs.This science
