A team of researchers from the University of Bonn, Heidelberg University and the National Autonomous University of Mexico has studied the critical behavior of light particles (photons) close to a phase transition. This critical scaling behavior, which sees thermodynamic quantities grow extremely large or diverge shortly prior to Bose-Einstein condensation, had never before been seen […]
Doubts about the standard model of cosmology are deepening after a new study identified fundamental problems in a recent analysis that defended the conventional view that the universe is currently undergoing accelerated expansion driven by dark energy.

While quantum computing could be the future, it is currently plagued by finicky hardware. To make the technology practical, researchers must demonstrate that it consistently and continuously works and performs at scale. In a new study, published in Physical Review Letters, researchers at Lawrence Livermore National Laboratory (LLNL) and the Ion Storage Group at the […]
The pickup truck, officials said, was illegally parked along the 100 block of East Capitol Street, where the U.S. Supreme Court building is also located; the block is near the U.S. Capitol and the Library of Congress

Researchers have discovered a thermal asymmetry deep beneath the surface across Mars’ southern hemisphere. Based on gravitational measurements that provide clues to the Red Planet’s interior structure, Mars’ southern interior is around 200 to 400 degrees Celsius warmer than the planet’s northern half and partially molten. The surprising finding adds context to Martian history and […]
The Roman Space Telescope is designed to directly image exoplanets using complex optomechanical systems developed by the Max Planck Institute for Astronomy

Since we cannot look into the interiors of stars and planets, we rely on lab experiments to replicate the physical processes that occur there. Led by the University of California, Los Angeles (UCLA), an international research team has produced the first experimental verification of a theoretically predicted flow state deemed characteristic of the interiors of […]
Efficiently controlling heat generation has become a major challenge as the semiconductors used in smartphones, computers and similar devices have become higher-performing and more miniaturized. The way heat is transmitted is determined by the vibration of the atoms that constitute a material, but it is not easy to directly examine, at the atomic scale, how […]
Saturn’s moon Enceladus sports a thick shell of ice surrounding a liquid water ocean. As though scraped by an enormous claw, four parallel cracks slash across its south pole. Each about 500 meters (1,600 feet) deep, 2 kilometers (1.2 miles) across and 130 kilometers (81 miles) long, the fissures spew water vapor and other materials […]
A gun-toting suspect fled from Hartford officers in a vehicle; when officers stopped the car, he got out and engaged in a shootout that left two officers wounded by gunfire

Stanford researchers have offered an explanation for why some sizzling, lava-covered worlds nestled tightly around their stars can retain their atmospheres. At such close quarters, intense stellar radiation should strip away a planet’s air.

Scientists have developed a new acoustic levitation technique using an ultrasonic beam capable of levitating and moving small objects in midair over distances of up to 40 cm (16 inches), six times farther than previously achieved using conventional methods. The study, carried out by a research team from the University of Tsukuba in Japan and […]
It has been a busy month for astronomy. In the midst of an eclipse season bookended by the total solar eclipse on Aug. 12 and the deep partial lunar eclipse coming up this week on Aug. 28, an outbound comet hanging high in the dawn sky just refuses to die: 220P/McNaught.
