Billions of light years away in a remote part of the universe, two neutron stars—the ultradense remnants of dead stars—collided. The catastrophic cosmic event sent light and particles, including a sudden flash of gamma rays, streaming through the universe. These gamma rays traveled for 8.5 billion years before reaching Earth.

NASA’s Van Allen Probe A is expected to reenter Earth’s atmosphere almost 14 years after launch. From 2012 to 2019, the spacecraft and its twin, Van Allen Probe B, flew through the Van Allen belts, rings of charged particles trapped by Earth’s magnetic field, to understand how particles were gained and lost. The belts shield […]
Due to climate change, plants’ pollination season has been growing longer and longer. As a result, people are exposed to allergens for extended periods each year, raising a major public health concern. Researchers from Embry‑Riddle Aeronautical University, the University of Rouen Normandy and the University of Lille have developed an advanced computational model of outdoor […]
Quantum mechanical effects are known to be easily disrupted by disturbances from the surrounding environment, commonly referred to as noise. To minimize these disturbances, physicists often study these effects in small and carefully controlled systems, in which environmental noise can be minimized.

No two snowflakes may be the same, but models that fail to take these variations into consideration often fall short when calculating the way snow accumulates on roofs. In Physics of Fluids, researchers from Harbin Institute of Technology in China modeled the way snow gathers on a roof based on snowflake size and distribution.

A new University of Mississippi study shows that some sound waves don’t just move forward—they also move slightly to the side. Understanding this movement could help researchers develop more precise acoustic tools. Likun Zhang, associate professor of physics and astronomy and senior scientist at the National Center for Physical Acoustics, published his team’s study on […]

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known as GRB 230906A, was likely caused by the collision of two neutron stars hundreds of millions of years ago and is now shedding light […]
A research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, cost-effective biosensors. The sensors integrate lasers and optics together on a centimeter-sized chip, which could move testing from hospitals to patients’ homes. This, in turn, would free up hospital beds and reduce visits to clinics.
