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.  Recommended viewing: What Is Implicit Bias, and How Might It Affect Your Next Medical Visit? https://www.scientificamerican.com/video/what-is-implicit-bias-and-how-might-it-affect-your-next-medical-visit/  E-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!

Polycystic ovary syndrome (PCOS) affects up to five million people in the U.S., yet it remains poorly understood. Many people with PCOS go undiagnosed while experiencing symptoms such as irregular periods, changes in hair and body shape, acne and infertility. Even after a diagnosis, they’re often told to lose weight to manage symptoms—advice that some researchers now say can be harmful.  A recent study found that people with PCOS are more likely to have eating disorders, regardless of their body mass index. Laura Cooney, an associate professor at the University of Wisconsin School of Medicine and Public Health, co-authored the study. She joins host Rachel Feltman to discuss why the focus on weight loss for PCOS treatment needs to be reconsidered.

As people live longer and family sizes shrink, fewer relatives are available to share the burden of caregiving for aging loved ones. The second episode of our two-part miniseries on caregiving explores what this means for the family members who take on this critical role. How do they provide the best care while also maintaining their own well-being? To hear firsthand how caregivers are navigating this challenge, Lauren Young and Tanya Lewis, Scientific American’s respective associate and senior editors of health and medicine, visited a support center in Queens, N.Y. Young shares some of the stories they gathered from the community there. Listen to part one of this series.

Discrimination may be speeding up the aging process for people of color and other minoritized groups. Research is revealing that structural and interpersonal racism could be key factors in why these communities often age faster and face age-related diseases sooner. Alexis Reeves, a postdoctoral researcher at Stanford University, studies how racism affects aging, with a focus on early menopause. In a conversation with Science Quickly host Rachel Feltman, Reeves discusses how traditional research methods might be overlooking these critical disparities.

Debris from satellites, rockets and other space infrastructure are crowding low-Earth orbit. Occasionally, that space junk crashes down to Earth. For Samantha Lawler, an associate professor of astronomy at the University of Regina in Saskatchewan, such debris was mostly a theoretical nuisance.

The American Cancer Society published a study suggesting that for 8 or 34 cancers tracked, case rates are rising from one generation to the next. While headlines often point to sedentary lifestyles and higher weights as a possible cause, some experts say that these factors alone cannot explain the spike.
