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

Pathways to a career in quantum: what skills do you need?

The quantum effect that could power next-gen, battery-free devices

A wafer-thin flake of bismuth telluride can act a little like a one-way street for electricity, even when the push comes from an alternating signal. But the direction of that “street” is not fixed.

A superradiant clock phase emerges when Rydberg atoms meet quantum light, simulations suggest

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and ...

Show HN: I wrote an LLM inference engine in pure Go – 48 tok/s zero dependencies

dlgo is a pure Go deep learning inference engine. It loads GGUF models and runs them on CPU with no dependencies beyond the standard library (SIMD acceleration is optional via CGo).I built this because I wanted to add local LLM inference to a Go project without shelling out to Python or linking against llama.cpp. The whole thing is go get github.com/computerex/dlgo and you're running models.It supports LLaMA, Qwen 2/3/3.5, Gemma 2/3, Phi-2/4, SmolLM2, Mistral,

Show HN: EdgeDox – Offline document AI on Android using Qwen3.5-0.8B

Hi HN,I’ve been experimenting with running small language models directly on mobile devices and built a small Android app called EdgeDox.The idea was to make document AI usable without sending files to a cloud service. Many existing tools require uploading PDFs or documents to a server, which can be a privacy concern.EdgeDox runs a lightweight language model (Qwen3.5-0.8B) locally on the device so documents stay on the phone.Current features:• Ask questions about PDFs • Document summarization •

Ask HN: Modeling executive function as a grey-box system: Valid or delusional?

I’ve spent the last year treating executive function attributes (Discipline, Grit, Patience, etc.) as mutable "system variables" instead of fixed traits.I’m taking a systems-engineering approach to “prescribe” CBT-based psychological interventions when I hit a wall (e.g. procrastination, "redlining"), and also to identify which traits need the most attention to optimize overall “system” (my) output.*Model Overview*:I’m using a Grey-Box model, dependent on the following premis

Antarctica has a strange gravity hole and scientists finally know why

Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity hole” to slow, deep movements of rock inside Earth that unfolded over tens of millions of years. Using earthquake data to essentially create a CT scan of the planet’s interior, researchers reconstructed how the anomaly evolved and discovered that it strengthened between about 50 and 30 million years

Physicists finally see strange magnetic vortices predicted 50 years ago

A team of physicists has experimentally confirmed a long-predicted sequence of exotic magnetic phases in an atomically thin material. When cooled, the material forms tiny magnetic vortices before transitioning into a second ordered magnetic state—exactly as predicted by a famous theoretical model from the 1970s. Observing both phases together for the first time validates key ideas about how magnetism behaves in two dimensions. The findings could help inspire ultracompact technologies built on na

Autonomous AI Agents Have an Ethics Problem

AI-powered digital assistants can do many complex tasks on their own. But who takes responsibility when they cause harm? Scott Shambaugh, a volunteer maintainer for a programming code library called Matplotlib, recently described a surreal encounter with an autonomous AI agent—a digital assistant created with a platform called OpenClaw. After he rejected a code contribution submitted by the agent, it researched and published a personalized “hit piece” against Shambaugh on its blog. The post port

Material previously thought to be quantum is actually a new, non-quantum state of matter

Magnetic materials in a quantum spin liquid phase are of great interest in the pursuit of exotic state of matter and quantum computation. But in the quantum realm, things are not always what they seem. A study, published in Science Advances and co-led by Rice University's Pengcheng Dai, found that the material cerium magnesium hexalluminate (CeMgAl11O19) was not actually in a quantum spin liquid phase despite evidence suggesting it was.

A superradiant clock phase emerges when Rydberg atoms meet quantum light, simulations suggest

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and develop quantum technologies, as they can give rise to exotic and rare phases of matter.
