Hubble and Beyond 2020-09-21 10:09:26 The universe is not just expanding; it's accelerating. Supermassive black holes are hunkered down at the center of our galaxy and just about every other galaxy, too. We talk about these and other big discoveries of the Hubble Space Telescope, now in orbit for 30 years. But two new next-generation telescopes will soon be joining Hubble: the Nancy Grace Roman Space Telescope and the James Webb Space Telescope. Hear what cosmic puzzles they'll address. Plus, life in a clean room while wearing a coverall "bunny suit"; what it takes to assemble a telescope. Guests:
Meg Urry - Professor of physics and astronomy, Director of the Yale Center for Astronomy and Astrophysics, Yale University
John Grunsfeld - Former NASA Associate Administrator, and astronaut
Kenneth Harris - Senior Project Engineer, Aerospace Corporation

Life on Venus? 2020-09-14 08:00:43 Have scientists found evidence of life on Venus? Known for its scorching temperatures and acidic atmosphere, Earth's twin hardly seems a promising place for living things. But could a discovery of phosphine by researchers at MIT point to a high-altitude biosphere on this nearby world? Guests:
Clara Sousa-Silva - Research scientist in MIT's Department of Earth, Atmospheric and Planetary Sciences. She and Sara Seager co-authored a paper in January 2020 titled, "Phosphine as a Biosignature Gas in Exoplanet Atmospheres"

Space: Why Go There? (rebroadcast) 2020-09-07 07:58:04 It takes a lot of energy and technology to leave terra firma. But why rocket into space when there's so much to be done on Earth? From the practical usefulness of satellites to the thrill of exploring other worlds, let us count the ways. The launch of a NOAA weather satellite to join its twin provides unparalleled observation of storms, wildfires, and even lightning. Find out what it's like to watch hurricanes form from space. Meanwhile, more than a dozen countries want their own satellites to help solve real-world problems, including tracking disease. Learn how one woman is helping make space accessible to everyone. Plus, now that we've completed our grand tour of the Solar System, which bodies are targets for return missions and which for human exploration? Guests:
Sarah Cruddas - Space journalist, broadcaster, and author based in the U.K.
Jamese Sims - GOES-R Project Manager at NOAA

Home Invasions 2020-08-31 08:12:00 As we struggle to control a viral invader that moves silently across the globe and into its victims, we are also besieged by other invasions. Murder hornets have descended upon the Pacific Northwest, threatening the region's honeybees. In Africa, locust swarms darken the sky. In this episode, we draw on a classic science fiction tale to examine the nature of invasions, and what prompts biology to go on the move. Guests:

The X-Flies (rebroadcast) 2020-08-24 07:21:58 Insect populations are declining. But before you say "good riddance," consider that insects are the cornerstone of many ecosystems. They are dinner for numerous animal species and are essential pollinators. Mammals are loved, but they are not indispensable. Insects are. Meanwhile, marvel at the extraordinary capabilities of some insects. The zany aerial maneuvers of the fly are studied by pilots. And, contrary to the bad press, cockroaches are very clean creatures. Also, take a listen as we host some Madagascar hissing cockroaches in our studio (yes, they audibly hiss). Plus, how insects first evolved ... and the challenges in controlling lethal ones. Are genetically-engineering mosquitoes the best way to combat malaria? Guests:
Erica McAlister - Entomologist, Senior Curator of diptera in the Department of Entomology, Natural History Museum in London, author of "The Secret Life of Flies"
Jessica Ware - Evolutionary biologist and entomologist at Rutgers University

Skeptic Check: Worrier Mentality (rebroadcast) 2020-08-17 08:20:30 Poisonous snakes, lightning strikes, a rogue rock from space. There are plenty of scary things to fret about, but are we burning adrenaline on the right ones? Stepping into the bathtub is more dangerous than flying from a statistical point of view, but no one signs up for "fear of showering" classes. Find out why we get tripped up by statistics, worry about the wrong things, and how the "intelligence trap" not only leads smart people to make dumb mistakes, but actually causes them to make more. Guests:
Eric Chudler - Research associate professor, department of bioengineering, University of Washington, Seattle and co-author of "Worried: Science Investigates Some of Life's Common Concerns"
Lise Johnson - Director of the Basic Science Curriculum, Rocky Vista University, and co-author of "Worried: Science Investigates Some of Life's Common Concerns"

Math's Paths (rebroadcast) 2020-08-10 08:23:11 If you bake, you can appreciate math's transformative properties. Admiring the stackable potato chip is to admire a hyperbolic sheet. Find out why there's no need to fear math - you just need to think outside the cuboid. Also, how nature's geometric shapes inspire the next generation of squishy robots and an argument for radically overhauling math class. The end point of these common factors is acute show that's as fun as eating Pi. Guests:

On Thin Ice (rebroadcast) 2020-08-03 08:31:47 Water is essential for life - that we know. But the honeycomb lattice that forms when you chill it to zero degrees Celsius is also inexorably intertwined with life. Ice is more than a repository for water that would otherwise raise sea levels. It's part of Earth's cooling system, a barrier preventing decaying organic matter from releasing methane gas, and a vault entombing ancient bacteria and other microbes. From the Arctic to the Antarctic, global ice is disappearing. Find out what's at stake as atmospheric CO2 threatens frozen H2O. Guests:
Peter Wadhams- Emeritus Professor of Ocean Physics at Cambridge University in the U.K. and the author of A Farewell to Ice: A Report from the Arctic

Skeptic Check: Know-It-Alls 2020-07-27 09:18:13 Think you're some kind of expert? Join the club. It's one thing to question authority; another to offer up your untrained self as its replacement. Rebellion may be a cherished expression of American individualism, but, from sidelining Dr. Fauci to hiding public health data, find out what we lose when we silence health experts and "go with our gut" during a pandemic. Plus, from ancestors to algorithms: how we've replaced credentialed experts with sketchy web sites and social media posts. Guests:
Charles Piller - Investigative reporter for Science magazine
Alison Galvani - Epidemiologist and Director of the Center for Infectious Disease Modeling and Analysis, at Yale University

Something in the Air 2020-07-20 08:53:12 Inhale. Now exhale. Notice anything different? Our response to the virus is changing the air in unexpected ways. A pandemic-driven pause on travel has produced clear skies and a world-wide air quality experiment. And a new study reveals that hundreds of tons of microplastics are raining down on us each day. But we can improve the quality of the breaths we do take; engineers have devised a high-tech mask that may kill coronavirus on contact. Plus, although you do it 25,000 times a day, you may not be breathing properly. Nose-breathing vs mouth breathing: getting the ins-and-outs of respiration. Guests:
Janice Brahney - Environmental biogeochemist at Utah State University
Sally Ng - Atmospheric scientist, chemical engineer at Georgia Tech.
Chandan Sen - Professor, department of surgery, Indiana University School of Medicine.

Debbie Millman: Designing Our Lives From prehistoric cave art to today's social media feeds, to design is to be human. This hour, designer Debbie Millman guides us through a world made and remadeand helps us design our own paths.
#574 State of the Heart This week we focus on heart disease, heart failure, what blood pressure is and why it's bad when it's high. Host Rachelle Saunders talks with physician, clinical researcher, and writer Haider Warraich about his book "State of the Heart: Exploring the History, Science, and Future of Cardiac Disease" and the ails of our hearts.
Insomnia Line Coronasomnia is a not-so-surprising side-effect of the global pandemic. More and more of us are having trouble falling asleep. We wanted to find a way to get inside that nighttime world, to see why people are awake and what they are thinking about.
So what'd Radiolab decide to do?
Open up the phone lines and talk to you.
We created an insomnia hotline and on this week's experimental episode, we stayed up all night, taking hundreds of calls, spilling secrets, and at long last, watching the sunrise peek through.
This episode was produced by Lulu Miller with Rachael Cusick, Tracie Hunte, Tobin Low, Sarah Qari, Molly Webster, Pat Walters, Shima Oliaee, and Jonny Moens.
