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: Turn – A compiled systems language for agentic computation
Hey HN,Over the last few years, we’ve seen an explosion of Python and TypeScript frameworks trying to wrangle LLMs. The problem is that they are bolting non-deterministic, probabilistic compute onto deterministic, sequential languages. You end up with 500 lines of Pydantic models, JSON-parsing retry loops, and async spaghetti just to coordinate two agents.I built Turn (https://turn-lang.dev) to solve this at the language level. It is a statically-typed, compiled language with a custom
Launch HN: OctaPulse (YC W26) – Robotics and computer vision for fish farming
Hi HN! My name is Rohan and, together with Paul, I’m the co-founder of OctaPulse (https://www.tryoctapulse.com/). We’re building a robotics layer for seafood production, starting with automated fish inspection. We are currently deployed at our first production site with the largest trout producer in North America.You might be wondering how the heck we got into this with no background in aquaculture or the ocean industry. We are both from coastal communities. I am from Goa, India a
Show HN: ParseForce – Turn emails into structured JSON and send them to webhooks
Hi HN,I built ParseForce because parsing emails has always been surprisingly painful.Many automation workflows still rely on incoming emails: invoices, order confirmations, shipping notifications, etc. The usual solutions involve fragile regex rules or Zapier-style email parsers that break when email formats change.ParseForce takes a different approach.You create a unique inbox and define the data you want to extract. Incoming emails are parsed using AI into structured JSON and delivered to your
Ask HN: Codex CLI error reveals "GPT-5.4-ab-arm2" string
While using codex CLI gpt-5.3-codex model, I just had a stream disconnect with a specific error message. It looks like I was routed to an A/B test for a 5.4 branch:<p>```
stream disconnected before completion: This user's access to gpt-5.4-ab-arm2-1020-1p-codexswic-ev3 has been temporarily limited for potentially suspicious activity related to cybersecurity.
```<p>Anyone else seeing GPT 5.4 variants?
Solution to HN getting overwhelmed problem
These days I go to new/ and it is overwhelming. Large quantity of low quality submissions.<p>Proposed solution: limit submissions to accounts with >X karma (eg. 500 karma) OR older than Y years (eg 5 years).<p>Both of these scale into the future as one can reach both conditions without ever submitting (eventually).
New Device Detects Brain Waves in Mini Brains Mimicking Early Human Development
The flower-shaped device wraps around brain organoids and maps nearly all electrical activity. Pea-sized brain blobs are a chatty bunch. Packed with neurons that spark with electrical activity, brain organoids—or “mini brains”—are a now popular way to study the human brain.Some organoids model the brain’s wiring during early development. Others, made from patients’ skin cells, retain DNA mutations that could lead to schizophrenia or autism. Scientists studying mini brains hope to find patterns a
Quantum dynamics show 'memory' depends on whether states or observables evolve
An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings show that a quantum process can appear memoryless from one perspective while retaining memory from another. The discovery opens new research avenues into quantum systems and technologies.

Mott and Kondo insulators—how external stimuli can modify electronic energy bands
A study from the Research Center for Materials Nanoarchitectonics (MANA) has uncovered a theoretical mechanism showing how the electronic band structures of strongly correlated insulators can be reshaped by spin and charge perturbations, opening up new possibilities for electronics with tunable band structures.
What is a quantum computer's speed limit? Entanglement can provide an answer
Since the 1990s, evidence has been growing that quantum computers should be able to solve a range of particularly complex computational problems, with applications in everything from supply chain ...

ChatGPT as a therapist? New study reveals serious ethical risks
As millions turn to ChatGPT and other AI chatbots for therapy-style advice, new research from Brown University raises a serious red flag: even when instructed to act like trained therapists, these systems routinely break core ethical standards of mental health care. In side-by-side evaluations with peer counselors and licensed psychologists, researchers uncovered 15 distinct ethical risks — from mishandling crisis situations and reinforcing harmful beliefs to showing biased responses and offerin
Superfluids emerge in 2D moiré crystal formed from time, study predicts
Conventional crystals are materials in which atoms arrange themselves in repeating spatial patterns. Time crystals, on the other hand, are phases of matter characterized by repeating motions over time without constantly heating up, breaking a physical rule known as time-translation symmetry.
Hidden oceans on icy moons may be boiling beneath the surface
Icy moons circling the outer planets may be far more dynamic—and explosive—than they appear. New research suggests that when heat from tidal forces melts their ice shells from below, the sudden drop in pressure could cause hidden oceans to boil beneath the surface. On smaller moons like Enceladus, Mimas, and Miranda, this process may help explain strange features such as Enceladus’ tiger stripes and Miranda’s towering cliffs.
A tiny twist creates giant magnetic skyrmions in 2D crystals
Twisting atomically thin magnetic layers does more than reshape their electronics—it can create giant, topological magnetic textures. In chromium triiodide, researchers observed skyrmion-like patterns stretching far beyond the expected moiré scale, reaching hundreds of nanometers. Even more surprising, their size doesn’t simply follow the twist pattern but peaks at a specific angle. This twist-controlled magnetism could pave the way for low-power spintronic devices built from geometry alone.
