Sky & Telescope Pocket Sky Atlas, 2nd Edition is a durable star atlas for planning sessions, identifying targets, and teaching celestial navigation.

About The Study: In this systematic review and meta-analysis, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) produced greater weight loss among women than men; however, their efficacy was consistent across other important subpopulations. These findings may inform clinical decision-making.
