In a potential watershed moment for physics, the first results from the Muon g-2 (pronounced gee minus two) experiment have strongly indicated that particles called muons deviate from precise predictions of their behavior in the standard model of…

A new mathematical approach called emulation dramatically decreases the amount of time necessary to solve equations describing key properties of atomic nuclei. The approach will help physicists run simulations far more quickly—and without the need…

Alpha particles, consisting of two protons and two neutrons but no electrons, are abundant in nature as radioactive decay products of heavy elements and familiar to us for the health risks they pose. Yet despite more than a century's-worth of…

For the first time, researchers have used the spin rates of black holes in the wide-ranging and ongoing search for dark matter. A recent study proposed that if a certain kind of dark matter particle, known as an ultralight boson, existed in a…

Particle physicists have reported the likely first-ever sighting of a long-theorized subatomic process known as a triangle singularity. The process involves a pair of particles, called kaons, exchanging one of their two constituent particles before…

The discovery of gravitational waves in 2015 revolutionized astronomy by opening up an entirely new way of studying extreme cosmic phenomena. Now researchers have reported the first evidence for a previously theorized but never-before-seen kind of…

Scrap tires are a common waste material, although markets do exist. According to the U.S. Tire Manufacturers Association, of the roughly 270 million scrap rubber tires generated each year in this country, about 100 million tires are used as fuel;…

Researchers searching for a hypothetical fourth type of neutrino have found no evidence for the particle, according to a new study. Very low-mass and highly abundant, neutrinos are elementary particles that barely interact with the rest of matter.…

With a miniature version of the kind of television antennas that often adorned rooftops before the advent of satellite and cable TV, researchers have demonstrated the conversion of electrical signals into light beamed in a particular direction. This…

A new study has shown that dangerous hydrogen-burning flames can persist in unexpectedly narrow spaces and with very low fuel volumes. The findings highlight potential challenges involved in the safe storage and transport of hydrogen gas, which…
