November, the month of the American Thanksgiving, seems an appropriate time to be grateful for mathematics, for our community, and especially for you our Notices readers. In appreciation we offer a feature on the difficulty of undoing the problem of antibiotic-resistant microbes, a sampler from the AMS Fall Western Sectional, a deep glimpse into the concept of varifold, a preview of the AMS two-day short course on discrete differential geometry, an account of immigration in the history of the Princeton Institute for Advanced Study, the Graduate Student section, and advice on writing a teaching recommendation letter and on making mathematics accessible to people with hearing loss. —Frank Morgan, Editor-in-Chief
