The inflammatory reaction in spinal cords of STAP-1 knockout (KO) mice was less severe than that of wild type (WT) mice (top panels). In parallel, spinal cords of STAP-1 KO mice exhibited less demyelination—loss of the myelin sheath that surrounds nerves—when compared with those of WT mice (bottom panels). (Kota Kagohashi, et al.

Researchers from Osaka University used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.
