Phys.org / Boron layers could set a superconductivity record, theoretical study predicts

Scientists in China predict that stacking two microscopic layers of boron could set a new record for superconductivity. Superconductors are materials that conduct electricity with zero resistance. Traditional types need temperatures ...

Phys.org / Galactic spins carry fingerprints of the primordial universe

The origin of spin in spiral and elliptical galaxies has posed a long-standing puzzle for astronomers. One idea, known as tidal torque theory, proposes that galaxies' spins are an imprinted record of the early universe, imparted ...

Phys.org / XENONnT detector narrows the hunt for dark matter

Using a detector filled with nearly 9 metric tons of liquid xenon, researchers have delivered some of the most sensitive dark matter results ever recorded. In the latest analysis from the XENON collaboration, working at the ...

Phys.org / Physicists watch a material's electrons assemble, and reassemble, into coexisting phases

A tall glass of ice water isn't just a thirst quencher; it's also an everyday example of coexisting phases. Water can exist simultaneously in both liquid and solid phases. As it turns out, this phase duality can also exist ...

Phys.org / Crossing into a mirror world: Particles turn to wisps of fog, and the magnetic monopole paradox dissolves

In Goethe's ballad "Erlkönig," immortalized in Schubert's fevered 1815 setting, a dying boy riding through the night sees a spectral king beckoning from the darkness. His father calms him: "Mein Sohn, es ist ein Nebelstreif"—my ...

Phys.org / Silver nanocatalysts switch reaction sites between power generation and hydrogen production

For the first time, researchers have discovered that the same silver (Ag) nanocatalyst operates at different reaction sites depending on whether a solid oxide cell is generating electricity or producing hydrogen. This finding ...

Phys.org / One million years without sex fails to erase stick insects' unused biological system

Scientists have made a surprising finding about how an asexually reproducing stick insect has evolved. Research led by Dr. Darren Parker, lecturer in evolutionary biology at Bangor University, studied the genes of several ...

Phys.org / An ultramassive white dwarf half Earth's size may hold a rare oxygen-neon core

Astronomers have found evidence that one of the most massive white dwarfs known has an oxygen-neon core instead of the more common carbon-oxygen core. The finding is important because the composition of a white dwarf's core ...

Phys.org / New AI model reveals the volume of the world's glaciers

How much ice is stored in the world's glaciers? And where exactly is it located? A new study led by Ca' Foscari University of Venice, in collaboration with the Institute of Polar Sciences of the National Research Council ...

Phys.org / Creating cleaner chemical reactions that run on oxygen and produce only water as waste

Oxygen provides the driving force for many vital chemical reactions. Two well-known examples include respiration, the process that allows living things to break down food to release its energy, and combustion, reactions that ...
