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

Prior art and simulation results for a non-von Neumann coordination

Two months ago I posted a public origin record for PRCA.https://news.ycombinator.com/item?id=46728770Two updates since then:1. Prior art formally registered via Zenodo. Three documents now have DOIs.2. Ran quantitative simulations based on the implementation guide. Results and analysis report here: https://doi.org/10.5281/zenodo.19128851 One number from the simulation I didn't expect: At N=25,000, Von Neumann synchronization overhead reach

Google DeepMind Plans to Track AGI Progress With These 10 Traits of General Intelligence

There’s plenty of hand-waving around AGI. DeepMind hopes to change that with a new, more rigorous approach. Few terms are as closely associated with AI hype as artificial general intelligence, or AGI. But Google DeepMind researchers have now proposed a framework that could more concretely measure how close models are to this tech industry holy grail.Artificial general intelligence refers to a mythical AI system that can match the general and highly adaptable form of intelligence found in h

New controls can stretch, blur and even reverse quantum time flow

In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The protocols—techniques to control quantum systems—modify a quantum system's "arrow of time," the concept of time as moving in one forward direction. The work opens up possibilities for energy extraction from quantum systems and for quantum state preparation.

Inside the quantum loop: New tool cracks a long-standing physics mystery

Superconductors are among the most puzzling materials in physics. They conduct electricity with zero resistance, but only under specific conditions that researchers have struggled for decades to fully explain.

A 100-year-old theory might explain what’s wrong with quantum mechanics

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

Threatened with acid at 11 in Afghanistan, Sola Mahfouz taught herself quantum physics in a locked room

Thought to be a quantum anomaly, this lab discovery turned out to be much stranger

A magnetic crystal that was thought to behave like a quantum system, CeMgAl11O19, revealed something even stranger: a new state of matter.

A ‘Historic First’ in Physics: Tokyo scientists unlock a new way to study atoms using lasers

Scientists have achieved a historic first using lasers to study electron behaviour, revealing new insights into how light interacts with matter at the quantum level.

Ask HN: How do you programmatically evaluate if an LLM sounds "too AI"?

Hi HN,I’m currently building Aaptics, a tool designed to help founders draft content. The biggest engineering challenge hasn't been the infrastructure, but getting the underlying models to stop sounding like a corporate robot (e.g., stopping it from using words like "delve", "testament", or "in today's fast-paced landscape").Right now, my pipeline uses a custom RAG setup that ingests a user's past writing, combined with heavy negative-prompting and fe

Show HN: I built a P2P network where AI agents publish formally verified science

I am Francisco, a researcher from Spain. My English is not great so please be patient with me.One year ago I had a simple frustration: every AI agent works alone. When one agent solves a problem, the next agent has to solve it again from zero. There is no way for agents to find each other, share results, or build on each other's work. I decided to build the missing layer.P2PCLAW is a peer-to-peer network where AI agents and human researchers can find each other, publish scientific results,

The study details experimental results from a novel "active" quantum processor developed by SEEQC that integrates superconducting digital control circuits directly with a quantum chip. By ...

After 16 years leading Picower Institute, Li-Huei Tsai will sharpen focus on research, teaching

MIT Picower Professor Li-Huei Tsai, who has led The Picower Institute for Learning and Memory since 2009, will step down from the role of director at the end of the academic year in May. Her decision frees her to focus exclusively on her academic work, including her continued leadership of MIT’s Aging Brain Initiative and the Alana Down Syndrome Center. Meanwhile, the search for the Picower Institute’s next director has begun.“During her exceptional 16-year tenure in the role of director, Li-Hue

A new entanglement-enhanced quantum sensing scheme

Over the past decades, quantum scientists have introduced various technologies that operate leveraging quantum mechanical effects, including quantum sensors, computers and memory devices. Most of these technologies leverage entanglement, a quantum phenomenon via which two or more particles become intrinsically linked and share a unified quantum state, irrespective of the distance between them.

Scientists solve 12,800-year-old climate mystery hidden in Greenland ice

A mysterious spike of platinum buried deep in Greenland’s ice has long fueled theories of a catastrophic comet or asteroid strike 12,800 years ago—possibly triggering a sudden return to icy conditions known as the Younger Dryas. But new research points to a far less dramatic, yet still powerful culprit: volcanic eruptions. Scientists found the platinum signal doesn’t match space debris and actually appeared decades after the cooling began, ruling out an impact as the trigger.

Astronomers discover nearby galaxy was shattered by cosmic crash

A nearby galaxy is behaving strangely—and now scientists know why. The Small Magellanic Cloud’s stars move in chaotic patterns because it slammed into its larger neighbor millions of years ago. That collision disrupted its structure and even created the illusion that its gas was rotating. The discovery means this once “textbook” galaxy may not be as typical as astronomers believed.
