A quantum mechanical trick called 'spin squeezing' is widely recognized to hold promise for supercharging the capabilities of the world's most precise quantum sensors, but it's been notoriously difficult to achieve. In new research, physicists describe how they've put spin squeezing within better reach. Nothing in science can be achieved or understood without measurement. Today

According to a new study, some of the earliest galaxies observed with the James Webb Space Telescope are in fact much less massive than they first appeared. Black holes in some of these galaxies make them appear much brighter and bigger than they really are. This helps resolve the debate over whether the size of

Laws that let bicyclists treat stop signs as yield signs lead neither riders nor motorists to act unsafely, according to a groundbreaking study. Laws that let bicyclists treat stop signs as yield signs lead neither riders nor motorists to act unsafely, according to a groundbreaking Oregon State University study. The project by OSU College of

New results from the world's most sensitive dark matter detector put the best-ever limits on particles called WIMPs, a leading candidate for what makes up our universe's invisible mass. Figuring out the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles

Researchers have announced a groundbreaking study using the Murchison Widefield Array (MWA) in Western Australia. The research is the first to search for signs of alien technology in galaxies beyond our own, focusing on low radio frequencies (100 MHz). This new approach looks at distant galaxies, making it one of the most detailed searches for

A multi-institutional team of scientists has developed a new superconductor material that could potentially be used in quantum computing and be a candidate 'topological superconductor.' A multi-institutional team of scientists in the United States, led by physicist Peng Wei at the University of California, Riverside, has developed a new superconductor material that could potentially be

A new study provides insights on the geophysics behind asteroid formation and evolution. When NASA's Double Asteroid Redirection Test (DART) spacecraft collided with an asteroid moon called Dimorphos in 2022, the moon was significantly deformed -- creating a large crater and reshaping it so dramatically that the moon derailed from its original evolutionary progression --

Researchers have developed molecular wires with periodic twists. By controlling the lengths of regions between twists, the electrical conductivity of individual polymer chains can be enhanced. This work may lead to novel organic electronics or single-molecule wires. From the high-voltage wires that carry electricity over long distances, to the tungsten filaments in our incandescent lights

A 3D quantum spin liquid has been discovered in the vicinity of a member of the langbeinite family. The material's specific crystalline structure and the resulting magnetic interactions induce an unusual behavior that can be traced back to an island of liquidity. An international team has made this discovery with experiments at the ISIS neutron

Superconductivity theory proposed by physics team validated in international experiment: Cooper pairs display wave-like distribution in Kagome metals, enabling new technological applications like superconducting diodes. For about fifteen years, Kagome materials with their star-shaped structure reminiscent of a Japanese basketry pattern have captivated global research. Only staring from 2018 scientists have been able to synthesize

Building on a landmark algorithm, researchers propose a way to make a smaller and more noise-tolerant quantum factoring circuit for cryptography. The most recent email you sent was likely encrypted using a tried-and-true method that relies on the idea that even the fastest computer would be unable to efficiently break a gigantic number into factors.

Scientists report incredibly small time delays in a molecule's electron activity when the particles are exposed to X-rays. To measure these tiny high-speed events, known as attoseconds, researchers used a laser to generate intense X-ray flashes that allowed them to map the inner workings of an atom. An international team of scientists is the first
