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
Why ‘quantum proteins’ could be the next big thing in biology

A new 'uncertainty relation' for quantum measurement errors
One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being measured—and therefore also the outcome of any subsequent measurement. How fast something is moving, for example, can depend on whether its position was measured beforehand.
Blasted off Mars and still alive
A famously resilient bacterium may be tough enough to survive one of the most violent events imaginable on Mars. In laboratory experiments designed to mimic the crushing shock of a massive asteroid impact, researchers squeezed Deinococcus radiodurans between steel plates and blasted it with pressures reaching 3 GPa (30,000 times atmospheric pressure). Even under these extreme conditions, a significant portion of the microbes survived.
James Webb spots a galaxy with tentacles in deep space
Astronomers using the James Webb Space Telescope have spotted the most distant “jellyfish galaxy” ever seen — a cosmic oddity streaming long, tentacle-like trails of gas and newborn stars as it speeds through a dense galaxy cluster. The galaxy appears as it was 8.5 billion years ago, revealing that the early universe may have been far more violent than scientists expected.
A flash of laser light flips a magnet in major light-control breakthrough
Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits with light.
The hidden technology that could unlock commercial fusion power
Fusion energy may be one of the most promising clean power sources of the future—but only if scientists can precisely measure the extreme, fast-moving plasmas that make it possible. A new U.S. Department of Energy–sponsored report urges major investment in advanced diagnostic tools—the high-tech “sensors” that track plasma temperature, density, and behavior inside fusion systems. Bringing together 70 experts from universities, national labs, and private industry, the workshop identified seven pr
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.
