New Upper Limit on the Axion-Photon Coupling with an Extended CAST Run with a Xe-Based Micromegas Detector.

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.

Bronchiolitis: Safely Doing Less Is the Next Big Thing.

Bronchiolitis is a viral lower respiratory tract infection primarily affecting children younger than 2 years; a common cause of health care encounters, including hospitalization; and a considerable economic burden for health care systems in the United States and worldwide. The American Academy of Pediatrics (AAP) most recently updated its bronchiolitis guideline in 2014 and reaffirmed supportive care as the mainstay of treatment. Despite these recommendations, there is still significant variability in care provided for these children, especially in bronchodilator usage, radiography, and high-flow nasal cannula.

Unmasking racial avoidance: Experimental evidence on parental school choice and public health policies during the Covid-19 pandemic.

Background: COVID-19 drastically changed the school choice landscape as families considered schools with varying public health protocols as well as academic and demographic characteristics. Our understanding of families' preferences during the pandemic is limited, however, because it primarily derives from surveys asking parents about a single school characteristic.

Objective: We aimed to understand how families' preferences for schools' racial composition and public health policies may interdepend.

Racialized Perceptions of Anticipated School Belonging.

Families indicate that fit and safety are priorities in school selections. It is not clear, however, whether school racial composition shapes families' perceptions of anticipated school belonging. Using a survey experiment with students and parents actively choosing NYC schools, I find that families expressed racialized judgments of belonging.
