Science Friday Folgen

A lot of things in life are squishy, including your skin, your organs, and all the goo inside you. But technology tends to be rigid and hard. Figuring out how to get those two worlds to work together can be challenging. How do you connect an electronic sensor to a soft, beating heart? As an inventor of biocompatible electronic devices, John A. Rogers has designed things like flexible probes, a pacemaker smaller than a grain of rice, and wireless sensors that stick to skin like a temporary tattoo. He joins Host Flora Lichtman to talk about the challenges of meshing the natural and artificial worlds, and his approach to science and technology development.Guest: Dr. John A. Rogers is a professor and director of the Querrey-Simpson Institute of Bioelectronics at Northwestern University.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

There’s a new wellness trend focused on an obscure capillary system that moves fluid around the body. Things like lymphatic walking, vibration plates, and compression boots have been touted as ways to stimulate the lymphatic system to combat bloating, flush away toxins, and generally promote health. So what is the lymphatic system, and what does it do? And is there anything to these claims? Flora gets some answers with the help of two experts: Timothy Padera, a researcher who has dedicated his career to better understanding how the lymphatic system works; and physical therapist Marc Miller, who treats cancer patients with manual lymphatic drainage. Guests:Dr. Timothy Padera is an investigator at Mass General Research Institute and a professor of radiation oncology at Harvard Medical School. Dr. Marc Miller is a certified lymphedema specialist and senior physical therapist at UT MD Anderson Cancer Center. Transcripts for each episode are available within 1-3 days at sciencefriday.com.  Subscribe to this podcast.

Perimenopause affects more than 4 billion people, but has historically been neglected by medicine. It’s the time before menopause when hormones start fluctuating wildly, leaving women with brain fog, hot flashes, dropping bone density, and mood changes. Thanks in part to social media, it’s more prominent in public discourse than it used to be.But it’s not just awareness that’s blown up: It’s also the promise that you don’t have to suffer like those before you, thanks to hormone therapy. After decades of controversy over prescribing estradiol and progesterone due to concerns of increased breast cancer and heart disease risk, new research has many providers reconsidering their approach.Joining Flora to sort out the science are reproductive endocrinologists Nanette Santoro and Genevieve Neal-Perry, who are both running some of the biggest long-term studies on perimenopause and the effects of hormone therapy. Guests:Dr. Nanette Santoro is a reproductive endocrinologist at the University of Colorado Anschutz and is the president of the Endocrine Society.Dr. Genevieve Neal-Perry is a reproductive endocrinologist and the OB-GYN department chair at the University of North Carolina at Chapel Hill.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
