no The South Pole’s IceCube detector catches a ghostly particle from deep space, and how rice knows to grow when submerged By traffic.omny.fm Published On :: Thu, 12 Jul 2018 14:00:00 -0400 A detection of a single neutrino at the 1-square-kilometer IceCube detector in Antarctica may signal the beginning of “neutrino astronomy.” The neutral, almost massless particle left its trail of debris in the ice last September, and its source was picked out of the sky by the Fermi Gamma-ray Space Telescope soon thereafter. Science News Writer Daniel Clery joins host Sarah Crespi to discuss the blazar fingered as the source and how neutrinos from this gigantic matter-gobbling black hole could help astronomers learn more about mysterious high-energy cosmic rays that occasionally shriek toward Earth. Read the research. Sarah also talks with Cornell University’s Susan McCouch about her team’s work on deep-water rice. Rice can survive flooding by fast internodal growth—basically a quick growth spurt that raises its leaves above water. But this growth only occurs in prolonged, deep flooding.

no Liquid water on Mars, athletic performance in transgender women, and the lost colony of Roanoke By traffic.omny.fm Published On :: Thu, 26 Jul 2018 14:00:00 -0400 Billions of years ago, Mars probably hosted many water features: streams, rivers, gullies, etc. But until recently, water detected on the Red Planet was either locked up in ice or flitting about as a gas in the atmosphere. Now, researchers analyzing radar data from the Mars Express mission have found evidence for an enormous salty lake under the southern polar ice cap of Mars. Daniel Clery joins host Sarah Crespi to discuss how the water was found and how it can still be liquid—despite temperatures and pressures typically inhospitable to water in its liquid form. Read the research. Sarah also talks with science journalist Katherine Kornei about her story on changing athletic performance after gender transition. The feature profiles researcher Joanna Harper on the work she has done to understand the impacts of hormone replacement therapy and testosterone levels in transgender women involved in running and other sports. It turns out within a year of beginning hormone replacement therapy, transgender women plateau at their new performance level and stay in a similar rank with respect to the top performers in the sport. Her work has influenced sports oversight bodies like the International Olympic Committee. In this month’s book segment, Jen Golbeck interviews Andrew Lawler about his book The Secret Token: Myth, Obsession, and the Search for the Lost Colony of Roanoke.

no <i>Science</i> and <i>Nature</i> get their social science studies replicated—or not, the mechanisms behind human-induced earthquakes, and the taboo of claiming causality in science By traffic.omny.fm Published On :: Thu, 30 Aug 2018 14:30:00 -0400 A new project out of the Center for Open Science in Charlottesville, Virginia, found that of all the experimental social science papers published in Science and Nature from 2010–15, 62% successfully replicated, even when larger sample sizes were used. What does this say about peer review? Host Sarah Crespi talks with Staff Writer Kelly Servick about how this project stacks up against similar replication efforts, and whether we can achieve similar results by merely asking people to guess whether a study can be replicated. Podcast producer Meagan Cantwell interviews Emily Brodsky of the University of California, Santa Cruz, about her research report examining why earthquakes occur as far as 10 kilometers from wastewater injection and fracking sites. Emily discusses why the well-established mechanism for human-induced earthquakes doesn’t explain this distance, and how these findings may influence where we place injection wells in the future. In this month’s book podcast, Jen Golbeck interviews Judea Pearl and Dana McKenzie, authors of The Book of Why: The New Science of Cause and Effect. They propose that researchers have for too long shied away from claiming causality and provide a road map for bringing cause and effect back into science. This week’s episode was edited by Podigy.

no The future of PCB-laden orca whales, and doing genomics work with Indigenous people By traffic.omny.fm Published On :: Thu, 27 Sep 2018 14:45:00 -0400 Science has often treated Indigenous people as resources for research—especially when it comes to genomics. Now, Indigenous people are exploring how this type of study can be conducted in a way that respects their people and traditions. Meagan Cantwell talks with contributing correspondent Lizzie Wade about a summer workshop for Indigenous scientists that aims to start a new chapter in genomics. We’ve known for decades that PCBs—polychlorinated biphenyls—are toxic and carcinogenic. In the 1970s and 1980s, these compounds were phased out of use in industrial and electronic applications, worldwide. But they are still in the environment—in soil and air—and in animal tissues, particularly those of killer whales. These toxic compounds start out at minute levels in tiny organisms, but as the small are eaten by the slightly larger, the PCB concentration increases—from plankton, to fish, to seals—until you are at killer whales with PCB-packed blubber. Ailsa Hall, director of the Sea Mammal Research Unit at St. Andrews University in the United Kingdom, talks with host Sarah Crespi about her group’s work measuring PCB levels in different killer whale populations and calculating the effect of PCBs on those populations 100 years from now. In this month’s book segment, Jen Golbeck interviews Damon Centola about his book How Behavior Spreads: The Science of Complex Contagions.

no Vacuuming potato-size nodules of valuable metals in the deep sea, and an expedition to an asteroid 290 million kilometers away By traffic.omny.fm Published On :: Thu, 21 Mar 2019 14:45:00 -0400 Pirate’s gold may not be that far off, as there are valuable metals embedded in potato-size nodules thousands of meters down in the depths of the ocean. Host Meagan Cantwell talks with Staff Writer Paul Voosen about the first deep-sea test of a bus-size machine designed to scoop up these nodules, and its potential impact on the surrounding ecosystem. In an expedition well above sea level, the Hayabusa2 spacecraft touched down on the asteroid Ryugu last month. And although the craft won’t return to Earth until 2020, researchers have learned a lot about Ryugu in the meantime. Meagan speaks with Seiji Sugita, a professor at the University of Tokyo and principal investigator of the Optical Navigation Camera of Hayabusa 2, about Ryugu’s parent body, and how this study can better inform future asteroid missions.

Today, scientists are tackling this blue-hued problem from many different angles. Host Sarah Crespi talks with contributing correspondent Kai Kupferschmidt about how scientists are looking to algae, bacteria, flowers—even minerals from deep under Earth’s crust—in the age-old quest for the rarest of pigments. Also this week, host Meagan Cantwell speaks with Andrew Whitehead, associate professor in the department of environmental toxicology at the University of California, Davis, about how the Atlantic killifish rescued its cousin, the gulf killifish, from extreme pollution. Whitehead talks about how a gene exchange occurred between these species that normally live thousands of kilometers apart, and whether this research could inform future conservation efforts.

Science journalist Sara Talpos talks with host Meagan Cantwell about how locals found the potentially health-harming chemicals in their water, and how contamination from nonstick chemicals isn’t limited to Michigan. Also this week, host Sarah Crespi talks with Shyamnath Gollakota of the University of Washington in Seattle about his work diagnosing ear infections with smartphones. With the right app and a small paper cone, it turns out that your phone can listen for excess fluid in the ear by bouncing quiet clicks from the speaker off the eardrum. Clinical testing shows the setup is simple to use and can help parents and doctors check children for this common infection. This week’s episode was edited by Podigy.

no Fossilized dinosaur proteins, and making a fridge from rubber bands By traffic.omny.fm Published On :: Thu, 10 Oct 2019 15:15:00 -0400 Have you ever tried to scrub off the dark, tarlike residue on a grill? That tough stuff is made up of polymers—basically just byproducts of cooking—and it is so persistent that researchers have found similar molecules that have survived hundreds of millions of years. And these aren’t from cook fires. They are actually the byproducts of death and fossilization. Host Sarah Crespi talks with Contributing Correspondent Gretchen Vogel about how these molecules can be found on the surface of certain fossils and used as fingerprints for the proteins that once dwelled in dinos. And Sarah talks with Zunfeng Liu, a professor at Nankai University in Tianjin, China, about a new cooling technology based on a 100-year-old observation that a stretched rubber band is warm and a relaxed one is cool. It’s going to be hard to beat the 60% efficiency of compression-based refrigerators and air conditioning units, but Zunfeng and colleagues aim to try, with twists and coils that can cool water by 7°C when relaxed.

no Science’s leading role in the restoration of Notre Dame, and the surprising biology behind how our body develops its tough skin By traffic.omny.fm Published On :: Thu, 12 Mar 2020 14:00:00 -0400 On this week’s show, freelance writer Christa Lesté-Lasserre talks with host Sarah Crespi about the scientists working on the restoration of Notre Dame, from testing the changing weight of wet limestone, to how to remove lead contamination from four-story stained glass windows. As the emergency phase of work winds down, scientists are also starting to use the lull in tourist activity to investigate the mysteries of the cathedral’s construction. Also this week, Felipe Quiroz, an assistant professor in the biomedical engineering department at the Georgia Institute of Technology and Emory University, talks with Sarah about his paper on the cellular mechanism of liquid-liquid phase separation in the formation of the tough outer layer of the skin. Liquid-liquid phase separation is when two liquids “demix,” or separate, like oil and water. In cells, this process created membraneless organelles that are just now starting to be understood. In this work, Quiroz and colleagues create a sensor for phase separation in the cell that works in living tissue, and show how phase separation is tied to the formation of the outer layers of skin in mice.
