Phys.org / What if dark matter came in two states?

The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...

Phys.org / The lengths male octopuses go to protect the arm they need to mate

For mating male octopuses, one limb is more important than all others. That is the third right arm or hectocotylus, which is used to transfer sperm to the female because the penis cannot do it directly. Losing the limb can ...

Phys.org / Physicists zero in on the mass of the fundamental W boson particle

When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the unknown. A particle that is just beyond its predicted mass can unravel scientists' assumptions about ...

Phys.org / Sound-sensing hair bundles in our ears act as tiny thermodynamic machines

The hair cells lining the inner ear are among the most sophisticated structures in the human body: capable of detecting sounds as faint as a whisper, while helping to maintain our sense of balance. Through new models detailed ...

Phys.org / AI trained like a Rubik's Cube solver simplifies particle physics equations

For years, Rutgers physicist David Shih solved Rubik's Cubes with his children, twisting the colorful squares until the scrambled puzzle returned to order. He didn't expect the toy to connect to his research, but recently ...

Phys.org / Summer is getting longer, and it's happening faster than we thought

Summer weather is arriving earlier, lasting longer and packing more heat than it used to—and it's happening faster than scientists had previously measured. A new study by UBC researchers has found that between 1990 and 2023, ...

Phys.org / Robust against noise, geometric-phase swap gates bring stability to quantum operations

Researchers at ETH Zurich have realized particularly stable quantum logical operations with qubits made of neutral atoms. Since these operations, called quantum gates, are based on geometric phases, they are extremely robust ...
