    Chasing Pluto, Space Warps. May 4, 2018, Part 1
    In July of 2015, the world was stunned to learn that Pluto, a tiny, distant dot that some didn’t even consider a planet, was a dynamic, complex, and beautiful world. But for scientists in pursuit of Pluto’s secrets since the late 1980s, it was a long wait. The mission faced political hurdles, budget battles, technical challenges, and near-disaster even as it was days away from speeding past Pluto. Alan Stern, the mission’s dogged principal investigator, and astrobiologist David Grinspoon have written a new book about the decades-long effort to visit Pluto. Last week we asked you to help us spot galaxies magnified by other galaxies—a phenomenon known as gravitational lensing. Over a million galactic glimpses later, we're ready to reveal what we found, including a galaxy more than seven billion light years away, and what appears to be a rare triple galactic lens. In this wrap-up segment, Space Warps co-founder Aprajita Verma and Zooniverse co-lead Laura Trouille share their favorite finds, and suggest a few other projects for armchair astronomers to dig into next. Plus, the end of net neutrality seemingly benefits corporations and harms consumers. But for small towns with slow internet speeds, this may not be the case. What does it mean for slow internet in rural Kansas?  And Rachel Feltman of Popular Science tells Ira about coral reefs and other science headlines in this week's News Round-up.

    Frozen Frogs, Yeast, Paleobotany. April 27, 2018, Part 2
    When winter comes, animals have several options for survival. They can leave their habitats entirely for warmer environments, search for a cozy cave, or even find insulation under a toasty snowbank. And if you’re a wood frog in chilly Ohio or Alaska, or the larvae of a certain wingless midge in Antarctica, you might also just stay put, and freeze solid until the sun returns. But to survive such extreme low temperatures, the bodies of these animals have made some special adaptations: sugars that act like antifreeze, and processes for keeping ice outside their cells to protect their tissues. Yeast helps your bread to rise and beer to brew, but did you know that there’s yeast in the guts of insects? Or that your body is covered—and filled—with yeast cells? In this segment, recorded live in Miami University’s Hall Auditorium in Oxford, Ohio, mycologist Nicholas Money helps Ira uncover the hidden world of the humble fungus. His new book “The Rise Of Yeast” details some of the ways that the ubiquitous microorganism has helped shape civilization, from baking to biotechnology. Paleontologists and anthropologists might look to the fossilized bones of early hominins to help fill in the evolutionary story of our species. But paleoecologists like Denise Su, curator and head of paleobotany and paleoecology at the Cleveland Museum of Natural History, are more interested in what type of environments these early human ancestors were living in millions of years ago.

    Historical Climate Change, Weighing Galaxies, Great Lakes Water Rights. April 27, 2018, Part 1
    It’s not uncommon these days to hear scientists and journalists say that our planet is experiencing record-setting temperatures due to climate change. But they’re talking about a small part of Earth’s history—human history. The story of the earth’s climate contains much more than what human beings have recorded. In their new book, Weather: An Illustrated History, longtime climate reporter Andrew Revkin and co-author Lisa Mechaley track the incredible range of climate history. They condense that history—from the formation of Earth’s early atmosphere to the invention of temperature, the tracking of tornados and the discovery of greenhouse gases—into a digestible timeline of 100 weather-related events. Science Friday is partnering with citizen science platform Zooniverse to help a team of astrophysicists identify galaxies showing an astronomical phenomenon known as gravitational lensing. Gravitational lensing occurs when the light coming from a galaxy, quasar, or other bright object is bent and distorted by a massive object in front of it, giving the light the appearance of passing through a “lens,” like how an image appears through a magnifying glass. These lenses are rare, but incredibly neat. So, a gravitational lens essentially allows us to weigh a galaxy. Pretty cool, right? But, we need your help to find more lenses! With the aid of the citizen science website Zooniverse, everyone can take part in this real, cutting-edge area of research. You can help contribute to making a real discovery! Plus, on this week's State of Science, Foxconn's Lake Michigan bid raises questions about interpreting a young law—when water is public and when it isn't.       Subscribe to this podcast.

    Ocean Migrations, Deep Divers, Summer Skies. April 20, 2018, Part 2
    Every night, the largest migration on Earth happens underwater, as jellies, crustaceans and fish swim up hundreds of meters towards the surface to feed. Those daily pilgrimages might also create propulsive jets behind the animals capable of stirring ocean waters, according to research in the journal Nature. Stanford engineer John Dabiri and his team investigated that phenomenon in the lab using brine shrimp (commonly known as sea monkeys). He joins Ira to discuss the theory. Plus: Consider the spleen. Many may not appreciate or even think about them very much at all, unless they’ve had them removed, but the Bajau people of Southeast Asia rely on them every day without even knowing it. The Bajau are “sea nomads,” meaning they get everything they need to live by diving up to 65 feet under water, multiple times, for up to 8 hours a day. But it’s not their large lung capacity that give them an advantage during a dive—it’s their extra large spleens. Dr. Melissa Ilardo, post-doctoral researcher in the Department of Molecular Medicine at the University of Utah, and Dr. Cynthia Beall, Professor of Anthropology at Case Western Reserve University, join Ira to discuss the spleen and other evolutionary adaptations that allow humans to survive in extreme environments. And it’s been a hard road getting there this year, but spring is finally in the air in much of the country. And that means summer is not far away, bringing with it warmer temperatures and lazy nights made for stargazing. Dean Regas, outreach astronomer at the Cincinnati Observatory and co-host of the PBS series ‘Star Gazers,’ joins Ira to talk about some of the highlights of the summer night skies, from planets to constellations to meteor showers.
