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

Forget Antibiotics: These Killer Cells Wipe Out Deadly Superbugs in a Day

The genetically engineered cells can be rewired to tackle a range of bacteria in the battle against antibiotic resistance. A mixture of bacteria lounge in a dish. Like the bugs populating our guts, most are benign or beneficial. But a deadly strain hides among them. These bacteria can easily escape last-line antibiotics, rapidly spread, and cause mayhem.But in this case, a single dose of genetically engineered cells hunts them down and wipes out nearly the entire population in a day, while leavi

A surprising new idea about how the Big Bang may have happened

Scientists at the University of Waterloo have uncovered a bold new way to explain how the universe began—one that could reshape our understanding of the Big Bang. Instead of relying on patched-together theories, their approach shows that the universe’s explosive early growth may arise naturally from a deeper framework called quantum gravity.

Show HN: We Built 450 Modular Agent Skills for Medical Research

Hi folks, I’m part of the team building AIPOCH. We just built an open-source library of 450+ executable Agent Skills designed specifically for medical research workflows.These skills built to work with OpenClaw and other AI agent platforms, including OpenCode and Claude. We have encoded specialized medical research logic directly into our Skills. 1. Scientific Integrity Constraints: Implementing Hard Rules 2. Study type identification: We identify the study type first, then execute different log

Show HN: Diffly – A Python package to compare polars dataframes

We built this after having to manually compare new pipeline outputs with older ones too many times to find out why they are different. It is a simple package that, given two polars dataframes and a primary key, produces a nicely formatted summary of differences. It also has some methods to investigate the differences more deeply.

Next-generation optical sensor can read photon spin across UV-to-infrared wavelengths

A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next-generation optical sensor technology capable of precisely detecting not only the intensity and wavelength of light but also its rotational direction—the spin information of photons. The team successfully implemented a quantum-dot-based optical sensor that can detect circularly polarized light (CPL) across an ultra-wide spectral range—from ultraviolet to short-wave infrare

Stabilized laser components could shrink quantum computers from room- to chip-scale

Scientists in the Riccio College of Engineering at the University of Massachusetts Amherst and the University of California Santa Barbara have demonstrated key laser and ion trap components necessary to help drastically shrink the size of quantum computers, an achievement aligned with the shrinking of integrated microprocessors in the 1970s, 80s and 90s that allowed computers to move from room-sized behemoths to today's ultrathin smartphones.

Pairs of atoms observed existing in two places at once for the first time

Quantum physicists at ANU have observed atoms entangled in motion. "It's really weird for us to think that this is how the universe works," says Dr. Sean Hodgman from the ANU Research School of Physics. "You can read about it in a textbook, but it's really weird to think that a particle can be in two places at once."

How systems science helps keep my flower delivery costs low

When you go out to run errands on the weekend, you're on a "tour" as defined by human mobility researchers. Same if you book a guided tour of a famous city or take a trip on a cruise boat that reaches multiple ports. A characteristic of such tours is that you begin and end up in the same place and take intermediate stops along the way. The number of stops is the tour's "length."

Quantum researchers engineer extremely precise phonon lasers

When lasers were invented in the 1960s, they opened new avenues for scientific discovery and everyday applications, from scanners at the grocery store to corrective eye surgery. Conventional lasers control photons—individual particles of light—but over the past 20 years, scientists have invented lasers that control other fundamental particles, including phonons—individual particles of vibration or sound. Controlling phonons could open even more possibilities with lasers, such as taking advantage

Finding the 'quantum needle' in a haystack: New filtering method can isolate photons

In quantum technologies, everything depends on the ability to detect the properties carried by a single photon. But in the real world, that photon of interest is often buried in a sea of unwanted light—a true "needle in a haystack" challenge that currently limits the deployment of many applications, including secure quantum communication, quantum sensors used in telescope networks, as well as the interconnection of quantum computers to accelerate the development of new drugs and materials.

Silicon quantum computer performs logical operations for the first time

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based spin qubits make it a promising material for scalable quantum computing. A new study, published in Nature Nanotechnology, has demonstrated silicon's use in a logical quantum processor, representing the first of its kind.

Framework unifies the classical and quantum Mpemba effects

Physicists have developed a new theoretical framework which unifies a wide array of seemingly unrelated "Mpemba effects": counterintuitive cases where systems driven further from equilibrium relax faster than those closer to it. Reporting their results in Physical Review X, researchers led by John Goold at Trinity College Dublin show that both classical and quantum versions of the effect can be understood using the same underlying logic—resolving a long-standing conceptual puzzle.

Scientists stretched a liquid and it snapped like a solid

Scientists have discovered something that seems almost impossible: under the right conditions, ordinary liquids can snap apart like solid objects. In experiments, researchers found that when certain liquids are stretched with enough force, they don’t just thin and flow—they suddenly fracture with a sharp break, much like metal under stress. This surprising behavior appears to be tied to viscosity, not elasticity, challenging long-held assumptions about how liquids behave.

Webb telescope spots mysterious explosion that defies known physics

Astronomers have spotted a bizarre cosmic explosion that refuses to play by the rules—and it’s leaving scientists scrambling for answers. GRB 250702B, detected by NASA’s James Webb Space Telescope and a global network of observatories, lasted an astonishing seven hours—far longer than typical gamma-ray bursts, which usually fade in under a minute.

Monster black holes are silencing star formation across the universe

A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of light-years away. This could explain why some galaxies near early quasars appear faint or missing. The finding suggests galaxies grow and evolve together, not in isolation.
