NASA’s Nancy Grace Roman Space Telescope team has successfully integrated the mission’s deployable aperture cover — a visor-like sunshade that will help prevent unwanted light from entering the telescope — to the outer barrel assembly, another structure designed to shield the telescope from stray light in addition to keeping it at a stable temperature.

Our cells constantly receive DNA damage from factors such as ultraviolet rays, irradiations, toxins and chemicals. For women, that can lead to poor egg quality, which in turn can cause infertility, miscarriage, birth defects or genetic disorders.

Researchers at the University of Missouri are now working to better understand a process that can help repair that damage.
