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: Dreamvibe – AI dream journal that maps dreams to 17 brain regions
I built a dream journaling app that uses AI to analyze dreams through Jungian psychology and neuroscience frameworks, then maps activation levels across 17 brain regions.The analysis extracts archetypes, symbols, shadow elements, and emotional themes from freeform text, then scores each brain region (amygdala, hippocampus, prefrontal cortex, etc.) based on dream content. The hardest part was getting structured data out of stream-of-consciousness writing without the AI hallucinating meaning that
Small Language Models (SLMs) vs. Large Language Models (LLMs)
AbstractThe last five years have seen explosive progress in large language models (LLMs) — exemplified by systems such as ChatGPT and GPT-4 — which deliver broad capabilities but at heavy computational, latency, privacy, and cost budgets. In parallel, a renewed research and engineering focus on Small Language Models (SLMs) — compact, task-optimized models that run on-device or on constrained servers — has produced techniques and models that close much of the gap while enabling new applications (
Show HN: I built a simple quant scanner for mean-reversion setups (ZcoreAI)
Hi HN — I built a small web app that scans a list of tickers across multiple timeframes and flags potential overbought/oversold mean‑reversion setups using a regression-channel Z‑score.Live MVP: https://zcoreai.onrender.com/What it does:Pick tickers + timeframes, then run a scanOutputs a matrix of signals (simple labels now; “expert” view shows exact values of Z-Score)Why:
I wanted something fast to answer “what’s oversold / overbought right now?” without opening all cha
Are the Mysteries of Quantum Mechanics Beginning To Dissolve?
N one of the leading interpretations of quantum theory are very convincing. They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or that a mysterious process causes quantumness to spontaneously collapse. This unsatisfying state was a key element of Beyond…Source
Time crystals could become accurate and efficient timekeepers
Time crystals could one day provide a reliable foundation for ultra-precise quantum clocks, new mathematical analysis has revealed. Published in Physical Review Letters, the research was led by Ludmila Viotti at the Abdus Salam International Center for Theoretical Physics in Italy. The team shows that these exotic systems could, in principle, offer higher timekeeping precision than more conventional designs, which rely on external excitations to generate reliably repeating oscillations.

Twin beams blast from a hidden star in stunning Hubble Space Telescope image
A dazzling new Hubble image peels back the layers of the mysterious Egg Nebula, a rare and fleeting phase in a Sun-like star’s death just 1,000 light-years away. Hidden inside a dense cocoon of dust, the dying star blasts twin beams of light through a polar opening, carving glowing lobes and delicate ripples into the surrounding cloud. These striking, symmetrical arcs hint that unseen companion stars may be shaping the spectacle from within.
Twisted 2D magnet creates skyrmions for ultra dense data storage
As data keeps exploding worldwide, scientists are racing to pack more information into smaller and smaller spaces — and a team at the University of Stuttgart may have just unlocked a powerful new trick. By slightly twisting ultra-thin layers of a magnetic material called chromium iodide, researchers created an entirely new magnetic state that hosts tiny, stable structures known as skyrmions — some of the smallest and toughest information carriers ever observed.
Porting an INT8 VHDL CNN from Intel Agilex 3 to Lattice Certus-NX
We implemented a small INT8 CNN for handwritten digit classification (NIST SD19 subset) in pure VHDL and built it on two different FPGA families: Intel Agilex 3 and Lattice Certus-NX.The design was originally targeting Agilex 3. We later rebuilt it for a Certus-NX board to see how portable the RTL actually was and what changed in terms of resource usage and timing.## ModelInput: 128×128 grayscale images streamed over UART from a host PC webcam.Architecture:
- 3×3 conv (8 filters) + pooling
- 3×3
Show HN: Running an LLM Inside Scratch
This runs the smallest llama2.c checkpoint (stories260K) inside Scratch/TurboWarp by compiling C inference code into Scratch blocks using llvm2scratch. The model is quantized to Q8_0 and packed into Scratch lists. If everything works, the sprite streams "Once upon a time..." token-by-token into its speech bubble.I started this as an experiment in how far Scratch's VM could be pushed, and because the idea of running an LLM inside Scratch felt absurd and fun. The main challenge
Show HN: Promptscout a local prompt enricher for Claude Code
I use Claude Code daily and got tired of repeatedly listing relevant files in prompts. So I built promptscout: a small local tool that takes your prompt + repo file tree and enriches the prompt with the most relevant files/paths, so Claude has a better starting point.<p>It uses a quantized Qwen 3 4B model and runs fully on your machine. I also added a Claude Code plugin via UserPromptSubmit that calls the CLI and swaps in the enriched prompt before the request goes to Claude.
New calcium-ion battery design delivers high performance without lithium
Scientists at HKUST have unveiled a major leap forward in calcium-ion battery technology, potentially opening the door to safer, more sustainable energy storage for everything from renewable power grids to electric vehicles. By designing a novel quasi-solid-state electrolyte made from redox-active covalent organic frameworks, the team solved long-standing issues that have held calcium batteries back—namely poor ion transport and limited stability.
Elon Musk Says SpaceX Is Pivoting From Mars to the Moon
It’s a dramatic shift from Musk’s long-standing goal of a permanent human presence on the red planet. Elon Musk has long said settling Mars is SpaceX’s raison d’être, but the world’s richest man has now pivoted his attention to the moon. The company is targeting an uncrewed lunar landing in March 2027 and has ambitions to create a “self-growing city” on our nearest celestial neighbor.The news marks a dramatic shift from Musk’s long-standing goal of a permanent human presence on the r
Asteroid Bennu reveals a new pathway to life’s chemistry
Dust from asteroid Bennu is revealing a surprising origin story for life’s building blocks. New research suggests some amino acids formed in frozen ice exposed to radiation, not warm liquid water as scientists long believed. Isotopic clues show Bennu’s chemistry differs sharply from well-studied meteorites, pointing to multiple pathways for creating life’s ingredients.
Radar evidence suggests a massive lava tube beneath Venus
Scientists have uncovered evidence of a massive underground lava tube hidden beneath the surface of Venus, revealing a new layer of the planet’s volcanic history. By reexamining radar data from NASA’s Magellan spacecraft, researchers identified what appears to be a huge empty conduit near the volcanic region Nyx Mons. The structure could be nearly a kilometer wide and extend for dozens of kilometers below the surface.

Cutting down on quantum-dot crosstalk: Precise measurements expose a new challenge
Devices that can confine individual electrons are potential building blocks for quantum information systems. But the electrons must be protected from external disturbances. RIKEN researchers have now shown how quantum information encoded into a so-called quantum dot can be negatively affected by nearby quantum dots. This has implications for developing quantum information devices based on quantum dots.
Physicists develop new protocol for building photonic graph states
Physicists have long recognized the value of photonic graph states in quantum information processing. However, the difficulty of making these graph states has left this value largely untapped. In a step forward for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have proposed a new scheme they term "emit-then-add" for producing highly entangled states of many photons that can work with current hardware.
