Muon magnetism could hint at a breakdown of physics’ standard model
After two decades, a new measurement of the muon magnetic anomaly reinforces earlier hints that its value disagrees with standard physics.

Newly made laser-cooled antimatter could test foundations of modern physics
Physicists have finally used laser cooling to tame unruly antimatter atoms. That could allow new tests of symmetry and Einstein’s theory of gravity.

Microscopic images reveal the science and beauty of face masks
Important insights into the particle-filtering properties of different fabrics also offer a sense of the unseen, textured world of face masks.

Uranium ‘snowflakes’ could set off thermonuclear explosions of dead stars
Uranium crystals that settle in the cores of white dwarfs could trigger nuclear chain reactions that blow the dead stars apart, a new study suggests.

Atomic clocks take a step toward redefining the second
Measurements of the clocks’ frequencies provide the most precise clock comparisons yet, with uncertainties less than a quadrillionth of a percent.

Can room-temperature superconductors work without extreme pressure?
The next generation of materials that conduct electricity with no resistance could shrug off the need for high pressure and low temperatures.
