Disparities in health are not indicated by adverse outcomes alone. Adriana Corredor-Waldron, an assistant professor of economics at NC State University, sought to understand why Black infants are more likely to be delivered by C-section than white infants. A working paper she co-authored found that the elevated number of low-risk Black pregnant people who were given C-section surgeries in New Jersey from 2008 to 2017 was likely caused by physician discretion. Corredor-Waldron explains why unnecessary C-sections can be risky and what medical education and financial incentives could do to close the gap.

A wildfire in Brooklyn, N.Y.’s Prospect Park was in part linked to drought conditions nationally. Plastic waste is set to grow with our expanding economy, but potential solutions look promising. Drops in gonorrhea and early-stage syphilis point to the first decline in sexually transmitted infections in 20 years. Voyager 2’s fly-by of Uranus in the 1980s collected data that led scientists to believe the planet’s moons were inactive.
