Menopause is having a moment. Celebrities like Halle Berry, Naomi Watts, and Michelle Obama have recently shared their personal menopause experiences. Menopause and perimenopause are showing up across social media and even in popular books. All this to say, menopause has finally gone mainstream. But, it wasn’t until about three decades ago that menopause research really kicked into gear. Since then, scientists have made a lot of progress in understanding the basic biological process as well as treatments like hormone therapy and the importance of separating symptoms of menopause from those of aging. Host Flora Lichtman talks with two menopause researchers, ob-gyn Monica Christmas and epidemiologist Carrie Karvonen-Gutierrez, about what we’ve learned so far—and what misconceptions bug them most.Guests: Dr. Monica Christmas is an associate professor of obstetrics and gynecology at the University of Chicago and director of the menopause program at UChicago Medicine.Dr. Carrie Karvonen-Gutierrez is an associate professor of epidemiology and the director of the Center for Midlife Science at the University of Michigan.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

The EPA recently announced that it’s going to shut down its scientific research arm, called the Office of Research and Development. Since the agency was founded nearly 55 years ago, it’s had in-house scientists researching things like pollutants in our air and water, and the risks posed by toxic chemicals. That research informs the EPA’s guidelines and standards.Host Flora Lichtman talks with Jennifer Orme-Zavaleta, who spent 40 years working at the EPA, about the importance of the Office’s research and what losing it means for public health and the environment.Guest: Dr. Jennifer Orme-Zavaleta spent 40 years working at the Environmental Protection Agency. She was the principal deputy assistant administrator for EPA’s Office of Research and Development.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

In December, the Parker Solar Probe made history when it made the closest-ever approach to the sun by a spacecraft. As it whizzed by, a camera recorded incredibly detailed images, which show the sun’s surface, the flow of solar winds, and eruptions of magnetized balls of gas. Seeing this activity in such detail could help scientists understand solar weather.Host Flora Lichtman talks with Parker Solar Probe project scientist Nour Rawafi about what these images show and how the probe could fundamentally change our understanding of the sun.Guest:Dr. Nour Rawafi is the Parker Solar Probe project scientist at the Johns Hopkins Applied Physics Laboratory in Maryland.Transcripts for each episode are available within 1-3 days at sciencefriday.com.   Subscribe to this podcast.
