A new study led by researchers from Ben-Gurion University of the Negev (BGU) reveals that living matter violates previously known physical principles of symmetry when cellular flows form and break down collective patterns. The research, published in Nature Physics, challenges conventional liquid-crystal physics by showing that moving single-celled bacteria and human respiratory cells spontaneously break mirror symmetry, moving in curved, irreversible spiral paths.
Scientists using the STAR detector to study particle collisions at the Relativistic Heavy Ion Collider (RHIC) have found an intriguing dip in their data in a relatively unexplored region of the nuclear phase diagram—a map of how nuclear matter behaves under various conditions of temperature and density. The dip appears in data tracking collision-by-collision variations in the momenta of particles emerging from collisions between gold nuclei at RHIC, near RHIC’s lowest collision energies. These collisions create the highest-density nuclear matter and may indicate that something interesting is happening in that dense region of the phase diagram. The findings are described in a paper just published in Physical Review Letters.
Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless they exert energy to move against it. Although it may be less intuitive, light waves or photons work similarly. To move against a stream of light, an object or particle, like a photon, must either have an external force acting on it or actively use energy to move upstream.
Science fiction suggests that life on other planets, if it exists, is likely far more advanced than life on Earth. A recent study suggests otherwise.
The Van Allen radiation belts are huge, doughnut-shaped regions of highly energetic charged particles trapped by Earth’s magnetosphere. These charged particles play a major role in space weather, so studying them is important for predicting and managing risks to satellites, astronauts, power grids and other infrastructure.
The more astronomers learn about the universe’s earliest galaxies, the stranger they seem. Many of their surprising properties may be explained by differences between their massive stars and those in galaxies like our own Milky Way. A new University of Utah-led survey with the Hubble Space Telescope is shedding light on the stellar astrophysics operating in early galaxies.
A research team led by Professor Jung-Il Hong of the Department of Physics and Chemistry at DGIST has successfully used current pulses to alter the spin configuration within a ferrimagnetic material, lowering its “compensation temperature”—the temperature at which opposing magnetizations cancel each other out—by up to approximately 110 K.
A Galveston County Sheriff’s deputy was captured on bystander video following a vehicle extremely closely without emergency lights activated
A “convergence” of city officials distracted police at the Bite of Seattle shooting scene from releasing information to the public, while budget constraints led to fewer cops staffing the event, Seattle PD stated
Exoplanets are exotic worlds orbiting distant stars far beyond our solar system. Ever since the first ones were discovered in the 1990s, astronomers have turned their attention to these distant worlds to understand more about them. Now, for the first time, scientists have detected radio signals coming directly from one of these planets, a massive gas giant named β Pictoris b.
The suspect was undergoing a medical evaluation after allegedly attacking an elderly couple when he gained access to the Ormond Beach officer’s holstered handgun
More and more details about 3I/ATLAS are filtering through the scientific process as time goes on. Our third known interstellar visitor attracted the attention of some of the world’s most powerful observatories when it was discovered in July 2025, and some of those telescopes found something peculiar—the isotopes it contained appeared different. A new paper submitted to The Astrophysical Journal Letters (and available as a preprint on arXiv) by Kenji Furuya of the RIKEN Pioneering Research Institute in Japan and his co-authors shows that the isotopic discrepancy is likely due to the “low metallicity” of the stellar nursery in which 3I/ATLAS was born.
An international team of astronomers from ASTRON, JIVE, the University of Amsterdam and other institutions has found the first so-called “microblazar” in the Milky Way. This stellar system is composed of a massive star and a black hole with a jet that is pointed toward Earth. The researchers also identified the region where the jet hits a molecular cloud as a place where particles are accelerated to ultra-high energies, likely up to petaelectronvolts. This would make microblazars one of the most powerful particle accelerators in the galaxy. The research was appears in Astronomy & Astrophysics.
Most kids learn in elementary school that the seasons are caused by Earth rotating on a tilted axis during its yearly orbit around the sun. The substantial tilt, about 23.5 degrees, is thought to be the result of an ancient planetary body, Theia, smashing into Earth about 4.5 billion years ago, in the same cataclysmic collision that formed the moon.
