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
Parkinson’s disease affects network of brain regions that controls whole-body action
Nature, Published online: 25 February 2026; doi:10.1038/d41586-026-00573-1Precision brain imaging of individuals with Parkinson’s disease reveals that the affected circuit is best characterized as a previously described network of brain regions called the somato-cognitive action network. Abnormally high connectivity in this network is associated with Parkinson’s disease and is normalized by effective pharmacological treatment and various brain-stimulation therapies.

Ion bombardment triggers a reliable quantum switch in tantalum disulfide crystals
When you toss a coin, you put it into a higher-energy state until it falls back down again. It can then end up in one of two possible states: heads or tails. No matter which state the coin was in before, after the toss both outcomes are equally likely. A team at TU Wien has analyzed a quantum system that also has two equivalent ground states. By supplying energy through ion bombardment, this state can be changed.
Scientists reveal a four-dimensional twist on photonic quantum logic
A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

Flat Molecules Aren’t Actually Flat. Blame Quantum Physics
In chemistry, molecules with a "flat" geometry are often stable enough to support a wide range of reactions. But in the quantum world, that's not technically true.
Breakthrough Simulation Reveals the "Metric Wall" of Spacetime, Unifying Black Hole Mechanics, Quantum Collapse, and the Big Bang by Raghu Kulkarni, CEO of IDrive Inc.

A simple chemical tweak could supercharge quantum computers
Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly adjusting the mix of tellurium and selenium in ultra-thin films. That tiny chemical tweak changes how electrons interact, effectively turning a quantum phase “dial” until the ideal state appears. The result is a more practical path toward building stable, next-generation quantum devices.

Show HN: Reduction Blockprint Planner/Simulator
I’ll start this by saying I am not a programmer. As such, I’ve used Claude Code to do most of the coding, so I expect some issues on the vibe coding front.As a hobby I do block printing - usually linoleum, sometimes I 3-d print plates to make prints. One of the techniques that I use to make multi-colored prints is called reduction printing (https://en.wikipedia.org/wiki/Printmaking). Instead of carving multiple blocks, one for each color, you use the same block, and with each
A small tool I made for local LLMs: LLM-neofetch-plus
Hey everyone!I've had this in mind for a while, and I finally did it: it shows system information like regular NeoFetch, but I've added extra features for those using local LLMs (Ollama, llama.cpp, etc.).For example:
-How much VRAM does your GPU have, which model (NVIDIA, AMD, Intel, Apple M series)?
-How many billions of parameters can your machine comfortably run (is 70B or 13B more sensible?)
-Which GGUF quantization does what (Q4_K_M vs Q8_0 vs)?
-Comparison of Ollama / llama.
