Hypothetical axions provide a compelling explanation for dark matter and could be emitted from the hot solar interior. The CERN Axion Solar Telescope has been searching for solar axions via their back conversion to x-ray photons in a 9-T 10-m long magnet directed toward the Sun. We report on an extended run with the International Axion Observatory pathfinder detector, doubling the previous exposure time.

Background: Educational attainment and income are often, but not always, associated with disease incidence. Existing research typically examines single diseases, resulting in disparate analyses with little comparability. In this study, we aimed to assess educational and income inequalities across diseases in Denmark.

Aim: Former patients and relatives of people who have received treatment in OPUS, a Danish specialized early intervention for first episode psychosis, have since 2009 worked to reduce stigma and increase hope related to schizophrenia and psychosis. They established The OpusPanel to share their own stories of living with an invisible disorder with new patients, health care professionals, politicians, and members of the public. The impact of The OpusPanel on stigma has not previously been explored or evaluated.

Reflective coatings are an essential feature of X-ray telescopes. Their overall performance relies heavily on substrate compatibility and how well they conform to the optics assembly processes. We use X-ray reflectometry (XRR) to demonstrate the compatibility of shaping flat substrates coated with iridium, and show that specular and nonspecular reflectance before and after shaping is on par with traditional hot-slumped coated substrates.
