A magnet made out of ytterbium atoms is only a billionth of a degree warmer than absolute zero. Understanding how it works could help physicists build high temperature superconductors
Because plasma can shape very intense light without being damaged, it could be used to make components for lasers thousands of times more powerful than the strongest ones that exist
A 2021 experiment achieved the landmark milestone of nuclear fusion ignition, which data analysis has now confirmed – but attempts to recreate it over the last year haven’t been able to reach ignition again
A maze of mirrors and lenses turns any material into a highly efficient light absorber and could be used for detection of faint light or charging distant devices with light
The rules of wrinkling are surprisingly hard to pin down. Using experiments, simulations and mathematical proofs, a team has uncovered how curved thin sheets of plastic will wrinkle when flattened
