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

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.
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.
Exercise rewires the brain — boosting the body’s endurance

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.

“My Optimistic Vision for 2050”
The following are prepared remarks that I delivered by Zoom to a student group at my old stomping-grounds of MIT, and which I thought might interest others (even though much of it will be familiar to Shtetl-Optimized regulars). The students asked me to share my “optimistic vision” for the year 2050, so I did my best to oblige. A freewheeling discussion then followed, as a different freewheeling discussion can now follow in the comments section.I was asked to share my optimistic vis
Photonic integrated circuits enable programmable non-Abelian 'braiding' of light states
A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of operations depends on their sequence, within an integrated photonic system.
Show HN: Consciousness Gateway – AI routing with consciousness-first alignment
I built a self-hosted AI gateway that implements all 3 layers of
the GATO alignment framework (Model, Agent, Network) using
consciousness-aware routing based on Donald Hoffman's conscious
agent theory.What makes it different from standard gateways:1. Product Algebra routing (Kronecker fusion) selects models based
on cross-modal interaction patterns, not just cost/capability2. Dharma constraints (no-self regularization, entropy optimization,
mindfulness, compassion) are built
