• Is There Such A Thing As Too Much Resolution On A TV?

  As Black Friday approaches, you’re probably being inundated with ads for bigger, better televisions. But just how good is good enough? Are there limits to what our eyes can even make out?Visual perception researcher Maliha Ashraf joins Host Flora Lichtman to describe her new study on display resolution—including a display calculator she and her colleagues developed to help you determine the optimal display characteristics for a given room. And retinal neuroscientist Bryan Jones joins the conversation to delve into the workings of human vision.Guests:Dr. Maliha Ashraf is a postdoctoral researcher at the University of Cambridge in the UK.Dr. Bryan W. Jones is a professor of ophthalmology at the University of Pittsburgh.Transcripts for each episode are available within 1-3 days at sciencefriday.com. Subscribe to this podcast.

• Can A Billion-Dollar Barricade Keep Carp Out Of The Great Lakes?

  Decades ago, non-native carp were brought onto fish farms on the Mississippi River to control algae and parasites. They escaped, thrived, and eventually flooded the Illinois River, outcompeting native species and wreaking havoc. If the carp find their way into the Great Lakes, they could do major damage to those vital ecosystems.There’s a proposed project to stop the fish—but it’s expensive, and not everyone agrees it’s the best solution. Host Flora Lichtman speaks with WBEZ and Grist reporter Juanpablo Ramirez-Franco and carp expert Cory Suski.Guests: Juanpablo Ramirez-Franco is an environmental reporter at WBEZ and Grist. Dr. Cory Suski is a professor of aquatic resources at the University of Illinois.Transcripts for each episode are available within 1-3 days at sciencefriday.com.  Subscribe to this podcast.

• Inside The Race To Save Wild Axolotls

  Axolotls are one of the most charismatic and beloved amphibians out there. But did you know that there’s only one place in the whole world where you can find them in the wild? It’s Lake Xochimilco in Mexico City.There, scientists are scrambling to save them from extinction by creating refuges, using environmental DNA to track them down, and tag-teaming with the farmers who work on the lake. Luis Zambrano, one of the world’s leading axolotl experts, and Alejandro Maeda-Obregón, a molecular biologist, talk with Host Flora Lichtman about their work to protect these beloved amphibians.Guests:
Dr. Luis Zambrano is a leading expert on axolotls and an ecologist at the National Autonomous University of Mexico.Dr. Alejandro Maeda-Obregón is a molecular ecologist at University College London who studies rare and endangered species.Transcripts for each episode are available within 1-3 days at sciencefriday.com.  Subscribe to this podcast.

• Endometriosis Is Common. Why Is Getting Diagnosed So Hard?

  Endometriosis is a painful disease that occurs when endometrium-like tissue grows outside of the uterus. It’s extremely common—if you have a uterus, you have a 1 in 10 chance of getting it. Yet, it takes seven years on average to receive a formal diagnosis. What does the latest science tell us about the biology of the condition and how to treat it? And why do so many people have such a difficult time getting diagnosed? Host Flora Lichtman is joined by endometriosis researcher and patient Linda Griffith to answer those questions and more. Guest: Dr. Linda Griffith is a biological engineer and Scientific Director of The MIT Center for Gynepathology Research.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

• Why Hasn’t Wave Energy Gotten Its Sea Legs Yet?

  We've figured out how to harness renewable energy from many natural systems, like solar, wind, and geothermal power. But what about the ocean’s waves? It might seem like converting wave power into electricity on a large scale would’ve been figured out by now, but the tech is actually just getting its sea legs. Why has it been so hard to develop? And just how promising is it?Host Flora Lichtman talks with Oregon Public Broadcasting reporter Jes Burns, who reported on Oregon’s massive wave energy test site; and then she checks in with Deborah Greaves, an  offshore renewable energy researcher, for a look at what’s happening in the rest of the world.Guests: Jes Burns is a science and environment reporter and host of "All Science. No Fiction." at Oregon Public Broadcasting.Dr. Deborah Greaves is a professor of ocean engineering at the University of Plymouth in England.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
