ai The places where HIV shows no sign of ending, and the parts of the human brain that are bigger—in bigger brains By traffic.omny.fm Published On :: Thu, 14 Jun 2018 15:00:00 -0400 Nigeria, Russia, and Florida seem like an odd set, but they all have one thing in common: growing caseloads of HIV. Science Staff Writer Jon Cohen joins host Sarah Crespi to talk about this week’s big read on how the fight against HIV/AIDS is evolving in these diverse locations. Sarah also talks with Armin Raznahan of the National Institute of Mental Health in Bethesda, Maryland, about his group’s work measuring which parts of the human brain are bigger in bigger brains. Adult human brains can vary as much as two times in size—and until now this expansion was thought to be evenly distributed. However, the team found that highly integrative regions are overrepresented in bigger brains, whereas regions related to processing incoming sensory information such as sight and sound tend to be underrepresented.

ai How our brains may have evolved for language, and clues to what makes us leaders—or followers By traffic.omny.fm Published On :: Thu, 02 Aug 2018 14:00:00 -0400 Yes, humans are the only species with language, but how did we acquire it? New research suggests our linguistic prowess might arise from the same process that brought domesticated dogs big eyes and bonobos the power to read others’ intent. Online News Editor Catherine Matacic joins host Sarah Crespi to talk about how humans might have self-domesticated themselves, leading to physical and behavioral changes that gave us a “language-ready” brain. Sarah also talks with Micah Edelson of the University of Zurich in Switzerland about his group’s research into the role that “responsibility aversion”—the reluctance to make decisions for a group—might play when people decide to lead or defer in a group setting. In their experiments, the team found that some people adjusted how much risk they would take on, depending on whether they were deciding for themselves alone or for the entire group. The ones who didn’t—those who stuck to the same plan whether others were involved or not—tended to score higher on standardized tests of leadership and have held higher military rank.

ai Doubts about the drought that kicked off our latest geological age, and a faceoff between stink bugs with samurai wasps By traffic.omny.fm Published On :: Thu, 09 Aug 2018 14:15:00 -0400 We now live in the Meghalayan age—the last age of the Holocene epoch. Did you get the memo? A July decision by the International Commission on Stratigraphy, which is responsible for naming geological time periods, divided the Holocene into three ages: the Greenlandian, the Northgrippian, and the Meghalayan. The one we live in—the Meghalayan age (pronounced “megalion”)—is pegged to a global drought thought to have happened some 4200 years ago. But many critics question the timing of this latest age and the global expanse of the drought. Staff writer Paul Voosen talks with host Sarah Crespi about the evidence for and against the global drought—and what it means if it’s wrong. Sarah also talks to staff writer Kelly Servick about her feature story on what happens when biocontrol goes out of control. Here’s the setup: U.S. Department of Agriculture researchers wanted to know whether brown marmorated stink bugs that have invaded the United States could be controlled—aka killed—by importing their natural predators, samurai wasps, from Asia. But before they could find out, the wasps showed up anyway. Kelly discusses how using one species to combat another can go wrong—or right—and what happens when the situation outruns regulators.

ai <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.

ai What we can learn from a cluster of people with an inherited intellectual disability, and questioning how sustainable green lawns are in dry places By traffic.omny.fm Published On :: Thu, 11 Oct 2018 14:45:00 -0400 A small isolated town in Colombia is home to a large cluster of people with fragile X syndrome—a genetic disorder that leads to intellectual disability, physical abnormalities, and sometimes autism. Spectrum staff reporter Hannah Furfaro joins host Sarah Crespi to discuss the history of fragile X in the town of Ricaurte and the future of the people who live there. Also this week, we talk about greening up grass. Lawns of green grass pervade urban areas all around the world, regardless of climate, but the cost of maintaining them may outweigh their benefits. Host Meagan Cantwell talks with Maria Ignatieva of The University of Western Australia in Perth and the Swedish University of Agricultural Sciences in Uppsala about how lawns can be transformed to contribute to a more sustainable future.

ai Mysterious racehorse injuries, and reforming the U.S. bail system By traffic.omny.fm Published On :: Thu, 28 Mar 2019 14:30:00 -0400 Southern California’s famous Santa Anita racetrack is struggling to explain a series of recent horse injuries and deaths. Host Meagan Cantwell is joined by freelance journalist Christa Lesté-Lasserre to discuss what might be causing these injuries and when the track might reopen. In our second segment, researchers are racing to understand the impact of jailing people before trial in the United States. Host Sarah Crespi talks with Online News Editor Catherine Matacic about the negative downstream effects of cash bail—and what research can tell us about other options for the U.S. pretrial justice system. Last up is books, in which we hear about the long, sometimes winding, roads that food can take from its source to your plate. Books editor Valerie Thompson talks with author Robyn Metcalfe about her new work, Food Routes: Growing Bananas in Iceland and Other Tales from the Logistics of Eating. This week’s episode was edited by Podigy. *Correction, 1 April, 12 p.m.: A previous version of this podcast included an additional research technique that was not used to investigate the Santa Anita racetrack.

ai How dental plaque reveals the history of dairy farming, and how our neighbors view food waste By traffic.omny.fm Published On :: Thu, 18 Apr 2019 14:45:00 -0400 This week we have two interviews from the annual meeting of AAAS in Washington D.C.: one on the history of food and one about our own perceptions of food and food waste. First up, host Sarah Crespi talks with Christina Warinner from the Max Planck Institute for the Science of Human History in Jena, Germany, about the history of dairying. When did people first start to milk animals and where? It turns out, the spread of human genetic adaptations for drinking milk do not closely correspond to the history of consuming milk from animals. Instead, evidence from ancient dental plaque suggests people from all over the world developed different ways of chugging milk—not all of them genetic. Next, Host Meagan Cantwell speaks with Sheril Kirshenbaum, co-director of the Michigan State University Food Literacy and Engagement Poll, about the public’s perception of food waste. Do most people try to conserve food and produce less waste? Better insight into the point of view of consumers may help keep billions of kilograms of food from being discarded every year in the United States. This week’s episode was edited by Podigy.

ai Grad schools dropping the GRE requirement and AIs play capture the flag By traffic.omny.fm Published On :: Thu, 30 May 2019 14:30:00 -0400 Up until this year, most U.S. graduate programs in the sciences required the General Record Examination from applicants. But concerns about what the test scores actually say about potential students and the worry that the cost is a barrier to many have led to a rapid and dramatic reduction in the number of programs requiring the test. Science Staff Writer Katie Langin joins host Sarah Crespi to talk about this trend and how it differs across disciplines. Also this week, Sarah talks with DeepMind’s Max Jaderberg in London about training artificial agents to play a video game version of capture the flag. The agents played approximately 4 years’ worth of Quake III Arena and came out better than even expert human players at both cooperating and collaborating, even when their computer-quick reflexes were hampered. And in this month’s book segment, new host Kiki Sanford interviews Marcus Du Satoy about his book The Creativity Code: Art and Innovation in the Age of AI. This week’s episode was edited by Podigy.

ai Breeding better bees, and training artificial intelligence on emotional imagery By traffic.omny.fm Published On :: Thu, 25 Jul 2019 15:00:00 -0400 Imagine having a rat clinging to your back, sucking out your fat stores. That’s similar to what infested bees endure when the Varroa destructor mite comes calling. Some bees fight back, wiggling, scratching, and biting until the mites depart for friendlier backs. Now, researchers, professional beekeepers, and hobbyists are working on ways to breed into bees these mite-defeating behaviors to rid them of these damaging pests. Host Sarah Crespi and Staff Writer Erik Stokstad discuss the tactics of, and the hurdles to, pesticide-free mite control. Also this week, Sarah talks to Philip Kragel of the Institute of Cognitive Science at the University of Colorado in Boulder about training an artificial intelligence on emotionally charged images. The ultimate aim of this research: to understand how the human visual system is involved in processing emotion. And in books, Kate Eichorn, author of The End of Forgetting: Growing Up with Social Media, joins books host Kiki Sanford to talk about how the monetization of digital information has led to the ease of social media sharing and posting for kids and adults.

ai Trying to find the mind in the brain, and why adults are always criticizing ‘kids these days’ By traffic.omny.fm Published On :: Thu, 17 Oct 2019 14:45:00 -0400 We don’t know where consciousness comes from. And we don’t know whether animals have it, or whether we can detect it in patients in comas. Do neuroscientists even know where to look? A new competition aims to narrow down the bewildering number of theories of consciousness and get closer to finding its biological signs by pitting different theories against each other in experimental settings. Freelance journalist Sara Reardon talks with host Sarah Crespi about how the competition will work. In our second segment, we talk about how we think about children. For thousands of years, adults have complained about their lack of respect, intelligence, and tendency to distraction, compared with previous generations. A new study out this week in Science Advances suggests our own biased childhood memories might be at fault.

ai Getting bisphenol A out of food containers, and tracing minute chemical mixtures in the environment By traffic.omny.fm Published On :: Thu, 23 Jan 2020 14:00:00 -0500 As part of a special issue on chemicals for tomorrow’s Earth, we’ve got two green chemistry stories. First, host Sarah Crespi talks with contributing correspondent Warren Cornwell about how a company came up with a replacement for the popular can lining material bisphenol A and then recruited knowledgeable critics to test its safety. Sarah is also joined by Beate Escher of the Helmholtz Centre for Environmental Research and the University of Tübingen to discuss ways to trace complex mixtures of humanmade chemicals in the environment. They talk about how new technologies can help detect these mixtures, understand their toxicity, and eventually connect their effects on the environment, wildlife, and people.

ai An ancient empire hiding in plain sight, and the billion-dollar cost of illegal fishing By traffic.omny.fm Published On :: Thu, 27 Feb 2020 14:00:00 -0500 This week on the podcast, Contributing Correspondent Lizzie Wade joins host Sarah Crespi to discuss a turning point for one ancient Mesoamerican city: Tikal. On 16 January 378 C.E., the Maya city lost its leader and the replacement may have been a stranger. We know from writings that the new leader wore the garb of another culture—the Teotihuacan—who lived in a giant city 1000 kilometers away. But was this new ruler of a Maya city really from a separate culture? New techniques being used at the Tikal and Teotihuacan sites have revealed conflicting evidence as to whether Teotihuacan really held sway over a much larger region than previously estimated. Sarah also talks with Rashid Sumaila, professor and Canada research chair in interdisciplinary ocean and fisheries economics at the University of British Columbia, Vancouver’s Institute for the Oceans and Fisheries. You may have heard of illegal fishing being bad for the environment or bad for maintaining fisheries—but as Sumaila and colleagues report this week in Science Advances, the illegal fishing trade is also incredibly costly—with gross revenues of between $8.9 billion and $17.2 billion each year. In the books segment this month, Kiki Sanford interviews Gaia Vince about her new book Transcendence How Humans Evolved through Fire, Language, Beauty, and Time.

ai Does coronavirus spread through the air, and the biology of anorexia By traffic.omny.fm Published On :: Thu, 09 Apr 2020 14:00:00 -0400 On this week’s show, Staff Writer Robert Service talks with host Sarah Crespi about a new National Academy of Sciences report that suggests the novel coronavirus can go airborne, the evidence for this idea, and what this means for the mask-wearing debate. See all of our News coverage of the pandemic here. See all of our Research and Editorials here. Also this week, Staff Writer Jennifer Couzin-Frankel joins Sarah to talk about a burgeoning understanding of the biological roots of anorexia nervosa—an eating disorder that affects about 1% of people in the United States. From genetic links to brain scans, scientists are finding a lot more biology behind what was once thought of as a culturally driven disorder. This week’s episode was produced with help from Podigy.
