Scientists see spins in a 2D magnet

Researchers at Columbia University have discovered a way to visualize magnons in a 2D material, CrSBr, by pairing them with excitons that emit light. This breakthrough enables the observation of tiny changes in magnon spins, potentially leading to the development of more efficient quantum information networks.

Lung cancer screening increases percentage of Stage I cases detected, while reducing percentage of Stage IV cases

A multicenter cohort study found that lung cancer screening increased the percentage of Stage I cases detected by 8.4% and reduced the percentage of Stage IV cases by 6.6%. The study suggests that implementation of screening achieves the desired effect of identifying early-stage lung cancers without resulting in overdiagnosis.
