    Jurassic World, Rhino Comeback, Uranus Collision. July 6, 2018, Part 2
    It’s the 25th anniversary of the debut of Jurassic Park. And with Jurassic World: Fallen Kingdom currently at the top of the summer movie food chain, its progeny continue to dominate the box offices. But even as the original Jurassic Park gave viewers the latest in paleontological science in dino looks, the research has progressed to include feathers and wildly different body shapes for old favorites like Tyrannosaurus and Velociraptor. Even newer research into dinosaur vocalization suggest they would have sounded more like modern birds than roaring lions. Paleontologists Julia Clarke and Ken Lacovara join John Dankosky to discuss. After the death of the last surviving male northern white rhino, the future looked dim for the endangered subspecies, which now numbers two infertile females. But scientists have been working on a number of methods to rescue the rhino after all. Collections of sperm and DNA could allow southern white rhinos, which are a closely related but a separate subspecies, to carry lab-created embryos to term. The icy planet Uranus is an odd place. It spins on an axis almost perpendicular to its orbit, with one pole pointed straight at the sun for much of the year. It’s also colder than expected and has an unusually-shaped magnetic field. One theory for how Uranus became such an oddball in our space neighborhood involves a massive impact strong enough to tip a young planet onto its side. A group of researchers ran the numbers on such a collision and simulated what the results might be if a planet one, two, or three times the size of the Earth were to strike Uranus in the early days of our solar system.  Subscribe to this podcast.

    Bee News, Summer Science Reading. June 29, 2018, Part 2
    Bumblebees and honeybees are two species of bees that form colonies. The colonies of bumblebees are smaller compared to their honeybee cousins, who’s hives can house tens of thousands of individuals. But both of these colonies have complicated compositions and structures that help them thrive. For bumblebees, recent studies showed that colonies located in urban areas may actually be more successful than nests located in agricultural areas. Plus, how do bees pick a new queen? Biologist Ash Samuelson and entomologist Ramesh Sagili join Ira to get the buzz. Plus, school is finally out! No more teachers! No more books! … Except the ones on our summer science reading list. From harvester ants to the ruts of ancient Rome, Annalee Newitz, tech culture editor for Ars Technica shares her picks written by scientists who really dig into their work. And Science Friday education director Ariel Zych sings the praises of a book about the stuff no one likes to talk about—human waste. So, act like a kid again and assign yourself a book or two from our summer science reading list. No book report required. Plus, check out the SciFri staff’s recommendations for summertime science beach reads.   Subscribe to this podcast.

    Beef Genetic Testing, Chasing Whales, Radiolab Gonads. June 29, 2018, Part 1
    Whales are majestic, awe-inspiring animals. Some species can reach up to 150 tons and take in a living room-sized volume of water in one gulp. They can even dive thousands of feet into the ocean while holding their breath all the way down. It’s hard to imagine that the earliest ancestors of these graceful creatures of the deep were four-legged dog-like animals that lived on land. In his book Spying on Whales: The Past, Present, and Future of Earth’s Most Awesome Creatures, paleontologist Nick Pyenson examines their evolutionary story. Plus: Think back to your sex ed class in school. Chances are you were introduced to lots of new jargon too: Terms like spermatozoa, oviducts, chromosomes, germ cells and gonads. It was that last word, gonads—and a researcher who referred to them as “magical organs”—that sent Radiolab producer and host Molly Webster on a quest to respark our fascination with embryonic development, X and Y chromosomes, and reproduction. The first few episodes of the limited-run series called Radiolab: Gonads are out now, and Molly joins Ira here to talk about it. And Sophie Bushwick, senior editor at Popular Science, joins Ira to talk about the James Webb Space Telescope and other news from the week in science, including the FDA’s approval of a marijuana-based medicine,  the discovery of a nursery for manta rays, and research into just how wiggly the tongue of a T. rex actually was.

    Math And Social Justice, Chicago Coyotes, Meteorites. June 22, 2018, Part 2
    Math isn’t often thought of as a tool for social justice. But mathematical thinking can help us understand what’s going on in society too, says mathematician Eugenia Cheng. For example, abstract math can be used to examine the power structures between men and women, or white and black people, and to more clearly define the relationships and power differentials at play. At our live event at the Harris Theater in Chicago, we called on WBEZ’s Curious City to help us out. Chicago resident Devin Henderson reached out to the Curious City team including editor Alexandra Solomon to learn more about the coyote population that call Chicago home. Wildlife biologist Chris Anchor, who’s part of Cook County’s Urban Coyote Project, talks about how coyotes made their way into Chicago and how they survive in an urban environment. Many people in Chicago probably remember the day meteorites fell from the sky. It’s known as the “Park Forest Meteor Shower” but it wasn’t the kind you stay up at night to watch streaking across the sky. Around midnight on March 27th, 2003, a meteorite exploded into pieces, showering the Chicago suburb of Park Forest, Illinois. People reported seeing stones falling through roofs and causing damage to homes. In the aftermath of the event, meteorite hunters descended on Park Forest looking to buy the rocks, creating a meteorite frenzy. But that didn’t stop Meenakshi Wadhwa, former curator of meteorites at the Chicago Field Museum, from getting her hands on one of these prized space rocks for the museum’s collection. Hear Ira and Chicago comedians Jimmy Adameck, Ross Taylor, and Jen Connor bring the event to life on stage in a play with musical scoring by Mary Mahoney.
