    Dinosaurs’ Secrets Might Be In Their Fossilized Poop
    To gaze upon a full T. rex skeleton is to be transported back in time. Dinosaur fossils are key to understanding what these prehistoric creatures looked like, how they moved, and where they lived.But there’s one type of dinosaur fossil that’s sometimes overlooked: poop. Its scientific name is coprolite. These fossilized feces are rarer than their boney counterparts, but they’re key to better understanding dino diets and ecosystems.This all raises an important question: How scientists know if something is fossilized dino poop or just a rock?At Science Friday Live in Boulder, Ira talks with Dr. Karen Chin, paleontologist and professor of geological sciences at the University of Colorado, Boulder to answer that question and much more.Transcripts for each segment will be available after the show airs on sciencefriday.com.

    The Promise Of Perovskite Solar Panels
    Solar holds great promise as a clean energy solution, as the sun is an incredibly abundant resource, and panels can be placed unobtrusively on roofs and in fields. And solar panel technology has advanced quite a bit over the past few decades: panels have become less expensive, more efficient, and more widely used. Panels also generally fare well, considering that they’re outside in inclement weather year after year.Recent advancements with perovskite solar cells—a type of cell whose name refers to the structure of a compound it contains—have many clean energy enthusiasts excited. Perovskite solar cells are a thin, flexible technology that can even be painted onto a structure and conduct electricity. Much of the work on these has been conducted at the National Renewable Energy Laboratory (NREL) based in Golden, Colorado.At Science Friday Live in Boulder, Colorado, Ira sat down with two solar experts from NREL, Dr. Joseph Berry and Dr. Laura Schelhas, to discuss perovskite solar cell advancements and the future of this clean energy technology.Transcripts for each segment will be available after the show airs on sciencefriday.com.

    An Expert Vegetable Breeder On Innovating Crops For The Future
    It’s become clear to farmers and home gardeners alike that climate change is affecting the gardening landscape, literally. The climate is warming, pests are moving into different regions, and there’s a growing need for vegetable varieties that are resilient to the stresses of this new age.In the world of organic farming, the job of creating those new varieties falls to a plant breeder: someone who, often painstakingly, crosses plants until they create a new variety. Dr. Jim Myers, one of the most accomplished plant breeders in the country, has lots of experience with this.Myers created the Indigo Rose tomato, a strikingly purple variety with the same antioxidants as blueberries. He also created the green bean cultivar predominantly used by Oregon producers, and is debuting two new varieties of low-heat habanero peppers next month, dubbed “Mild Thing” and “Notta Hotta.”Myers joins Ira Flatow from Corvallis, Oregon, where he’s a professor of agricultural science at Oregon State University. They discuss his decades-long career in plant breeding and what he sees as the biggest challenges for the plant breeders of the future. Subscribe to this podcast.

    What The Private Sale Of Fossils Means For Paleontology
    On July 17, Apex the stegosaurus was sold at Sothebys in New York City for a record $44.6 million. The buyer was billionaire Ken Griffin, CEO of the hedge fund Citadel, who says he plans to loan the fossil to American institutions for display.But despite Griffin’s statement, some paleontologists aren’t too happy about the trend of fossils going up for auction.The sale of dinosaur fossils has become more and more profitable in recent years. Eight out of the ten most expensive fossils have been sold in the last four years. This trend of rising sale prices leaves museums and research institutions unable to pay for fossils that could benefit paleontological research.Paleontologists fear that as more and more fossils become privately owned, the availability of fossils for research and even access to dig sites might decrease or be restricted.SciFri guest host and producer Kathleen Davis is joined by Dr. Steve Brusatte, professor of paleontology at the University of Edinburgh in Scotland to talk about the potential scientific impacts of privatizing and selling fossils.Transcript for this segment will be available after the show airs on sciencefriday.com.
