Space Rocks!

From Big Picture Science - It's not a bird or a plane, and probably not an alien spaceship, although the jury's still deliberating that one.  Some astronomers have proposed that an oddly-shaped object that recently passed through our Solar System could be an alien artifact. We consider the E.T. explanation for 'Oumuamua, but also other reasons asteroids are invigorating our imagination.  Are these orbiting rocks key to our future as a spacefaring species? Find out why traditional incentives for human exploration of space - such as political rivalry -aren't igniting our rockets the way they once did, but why the potentially trillions of dollars to be made mining asteroids might. These small bodies may also hold the key to our ancient past: the New Horizons flyby of Thule in early 2019 will provide an historic look at a distant Kuiper belt object, and provide clues about the formation of the Solar System. Guests: Roger Launius - Former associate director of the National Air and Space Museum at the Smithsonian and chief historian for NASA J. L.Galache - Asteroid astronomer and co-founder and CTO of Aten Engineering Mark Showalter - Planetary scientist and Senior Research Scientist at the SETI Institute and a member of the New Horizons team Avi Loeb - Professor of Science at Harvard and chair of the Department of Astronomy

Skeptic Check: Science Denial
2018-11-12 07:41:10
Climate change isn't happening.  Vaccines make you sick.  When it comes to threats to public or environmental health, a surprisingly large fraction of the population still denies the consensus of scientific evidence.  But it's not the first time - many people long resisted the evidentiary link between HIV and AIDS and smoking with lung cancer. There's a sense that science denialism is on the rise.  It prompted a gathering of scientists and historians in New York City to discuss the problem, which included a debate on the usefulness of the word "denial" itself.  Big Picture Science was there. We report from the Science Denial symposium held jointly by the New York Academy of Sciences and Rutgers Global Health Institute.  Find out why so many people dig in their heels and distrust scientific findings.  Plus, the techniques wielded by special interest groups to dispute some inconvenient truths.  We also hear how simply stating more facts may be the wrong approach to combating scientific resistance. Guests: Melanie Brickman Borchard - Director of Life Sciences Conferences at New York Academy of Sciences Nancy Tomes - professor of history at Stony Brook University Allan Brandt - professor of history of science and medicine at Harvard University. Author of "The Cigarette Century: The Rise, Fall, and Deadly Persistence of the Product that Defined America" Sheila Jasanoff - Director of Program on Science, Technology and Society and professor of environment, science and technology at Kennedy School of Government at Harvard University Michael Dahlstrom - Associate Director of Greenlee School of Journalism and Communication, and associate professor at Iowa State University Matthew Nisbet - professor of communication and public policy at Northeastern University Arthur (Art) Caplan - professor and founding head of medical ethics at NYU School of Medicine

SMS isn't the original instant messaging system.  Plants can send chemical warnings through their leaves in a fraction of a second.  And while we love being in the messaging loop - frenetically refreshing our browsers - we miss out on important conversations that no Twitter feed or inbox can capture. That's because eavesdropping on the communications of non-human species requires the ability to decode their non-written signals. Dive into Arctic waters where scientists make first-ever recordings of the socializing clicks and squeals of narwhals, and find out how climate shifts may pollute their acoustic landscape.  Also, why the chemical defense system of plants has prompted one biologist to give greenery an "11 on the scale of awesomeness." And, you can't see them, but they sure can sense one another: how communicating microbes plan their attack. Guests: Susanna Blackwell - Bio-acoustician with Greeneridge Sciences. Hear her recordings of narwhals here. Simon Gilroy - Professor of botany, University of Wisconsin, Madison. His video of glowing green caterpillar-munched plants can be viewed here.

DNA is Not Destiny
2018-10-15 08:29:44
Heredity was once thought to be straightforward.  Genes were passed in an immutable path from parents to you, and you were stuck - or blessed - with what you got.  DNA didn't change.  But now we know that's not true.   Epigenetic factors, such as your environment and your lifestyle, control how your genes are expressed.  Meanwhile, the powerful tool CRISPR allows us to tinker with the genes themselves.  DNA is no longer destiny. Hear the results from the NASA twin study and what happened to astronaut Scott Kelly's DNA after a year on the International Space Station.  Plus, whether there's evidence that epigenetic changes can be passed down.  And, if we can wipe out deadly malaria by engineering the mosquito genome for sterility, should we do it? Guests: Scott Kelly - Former military test pilot and astronaut and author of "Infinite Wonder" Carl Zimmer - Columnist for The New York Times, author of "She Has Her Mother's Laugh: The Powers, Perversions, and Potential of Heredity" Christopher Mason - Associate professor of genetics and computational biology at Weill Cornell Medicine Michael Snyder - Chair of the genetics department and director of the Center for Genomics and Precision Medicine at Stanford University Nicole Gladish - PhD candidate, department of medical genetics, University of British Columbia


Creature Discomforts
2018-10-08 07:47:27
Okay you animals, line up: stoned sloths, playful pandas, baleful bovines, and vile vultures.  We've got you guys pegged, thanks to central casting.  Or do we?  Our often simplistic view of animals ignores their remarkable adaptive abilities.  Stumbly sloths are in fact remarkably agile and a vulture's tricks for thermoregulation can't be found in an outdoors store.  Our ignorance about some animals can even lead to their suffering and to seemingly intractable problems.  The South American nutria was brought to Louisiana to supply the fur market.  But the species got loose and tens of millions of these rodents are destroying the environment.  It literally has a bounty on its tail. Hear about research that corrects a menagerie of misunderstandings about our fellow furry, feathered, and scaly animals, and how getting over ourselves to know them better can have practical benefits. Will you still recoil from termites if you learn that they are relevant to the future of robots, global warming, and smart design? Guests: Lucy Cooke - Zoologist, broadcaster and author of "The Truth About Animals: Stoned Sloths, Lovelorn Hippos, and Other Tales from the Wild Side of Wildlife" Chris Metzler - Co-director and producer of the film Rodents of Unusual Size Lisa Margonelli - Journalist and author of "Underbug: An Obsessive Tale of Termites and Technology"


Skeptic Check: Heal Thyself
2018-09-24 08:29:04
Do we still need doctors?  There are umpteen alternative sources of medical advice, including endless and heartfelt health tips from people without medical degrees. Frankly, self-diagnosis with a health app is easier and cheaper than a trip to a clinic.   Since we're urged to be our own health advocate and seek second opinions, why not ask Alexa or consult with a celebrity about what ails us? Find out if you can trust these alternative medical advice platforms.  Plus, lessons from an AIDS fighter about ignoring the findings of medical science.   And, if AI can diagnose better than an MD, will we stop listening to doctors altogether? It's our monthly look at critical thinking ... but don't take our word for it! Guests: Katherine Foley - Science and health reporter at Quartz, and author of the article "Alexa is a Terrible Doctor" Paul Offit - Professor of pediatrics at the Children's Hospital of Philadelphia and the Perlman School of Medicine at the University of Pennsylvania, and author of "Bad Advice: Or Why Celebrities, Politicians, and Activists Aren't Your Best Source of  Health Information" Richard Marlink - Director Rutgers Global Health Institute.

New Water Worlds
2018-08-27 08:05:54
The seas are rising.   It's no longer a rarity to see kayakers paddling through downtown Miami.  By century's end, the oceans could be anywhere from 2 to 6 feet higher, threatening millions of people and property.  But humans once knew how to adapt to rising waters.  As high water threatens to drown our cities, can we learn do it again. Hear stories of threatened land: submerged Florida suburbs, the original sunken city (Venice), and the U.S. East Coast, where anthropologists rush to catalogue thousands of low-lying historical and cultural sites in harm's way, including Jamestown, Virginia and ancient Native American sites.   But also, stories of ancient adaptability: from the First American tribes of the Colusa in South Florida to the ice age inhabitants of Doggerland.  And, modern approaches to staying dry: stilt houses, seawalls, and floating cities. Guests: Jeff Goodell- Journalist and author of "The Water Will Come: Rising Seas, Sinking Cities, and the Remaking of the Civilized World" Brian Fagan- Archaeologist and Emeritus Professor of Anthropology, University of California Santa Barbara, and author of many books including "The Attacking Ocean: the Past, Present, and Future of Rising Sea Levels"  David Anderson- Professor of Anthropology, University of Tennessee.  His team's PLOS ONE paper is "Sea-level rise and archaeological site destruction." His DINAA site can be used to generate maps of where people were living in the past, up to ca. 15,000 years ago.  


It's Habitable Forming
2018-08-13 06:25:58
There's evidence for a subsurface lake on Mars, and scientists are excitedly using the "h" word.  Could the Red Planet be habitable, not billions of years ago, but today?  While we wait - impatiently - for a confirmation of this result, we review the recipe for habitable alien worlds. For example, the moon Titan has liquid lakes on its surface.  Could they be filled with Titanites? Dive into a possible briny, underground lake on Mars ... protect yourself from the methane-drenched rain on a moon of Saturn ... and cheer on the missed-it-by-that-much planets, asteroids Ceres and Vesta. Also, do tens of billions of potentially habitable extrasolar planets mean that Earth is not unique? Guests: Nathalie Cabrol - Planetary scientist, Director of the Carl Sagan Center for the Study of Life in the Universe at the SETI Institute Jack Holt - Geophysicist, Lunar and Planetary Laboratory, University of Arizona Jani Radebaugh - Planetary scientist and professor of geology, Brigham Young University Marc Rayman -  Mission Director and Chief Engineer of NASA's Dawn Mission Phil Plait - Astronomer, blogger, and widely known as the Bad Astronomer


Skeptic Check: Brain Gain
2018-08-06 07:35:13
Looking to boost your brainpower?  Luckily, there are products promising to help.  Smart drugs, neurofeedback exercises, and brain-training video games all promise to improve your gray matter's performance.  But it's uncertain whether these products really work.  Regulatory agencies have come down hard on some popular brain training companies for false advertising. But other brain games have shown benefits in clinical trials.  And could we skip the brain workout altogether and pop a genius pill instead?  In our monthly look at critical thinking, we separate the pseudo from the science of commercial cognitive enhancement techniques. Guests: Caroline Williams- Science journalist and author of "My Plastic Brain: One Woman's Yearlong Journey to Discover If Science Can Improve Her Mind" Adam Gazzaley- Neuroscientist, University of California, San Francisco, and the executive director of Neuroscape.  His book is "The Distracted Mind: Ancient Brains in a High Tech World."   Amy Arnsten- Professor of neuroscience and psychology at Yale Medical School Kevin Roose- Journalist for the New York Times. Leonard Mlodinow- Physicist and author of "Elastic: Flexible Thinking in a Time of Change"


Identity Crisis
2018-07-23 08:25:36
DNA is the gold standard of identification.  Except when it's not.  In rare cases when a person has two complete sets of DNA, that person's identity may be up in the air.  Meanwhile, DNA ancestry tests are proving frustratingly vague: dishing up generalities about where you came from rather than anything specific.  And decoding a genome is still relatively expensive and time-consuming.   So, while we refine our ability to work with DNA, the search is on for a quick and easy biomarker test to tell us who we are.   In this hour: the story of chimeras - people who have two sets of DNA; a reporter whose ancestry tests revealed she is related to Napoleon and Marie Antoinette; and the eyes have it in Somaliland, the first nation to use iris scans in an election.  Find out why your irises may be what ultimately distinguishes you from the crowd.


Free Range Dinosaurs
2018-06-25 08:31:45
Dinosaurs are once again stomping and snorting their way across the screen of your local movie theater.  But these beefy beasts stole the show long before CGI brought them back in the Jurassic Park blockbusters.  Dinosaurs had global dominance for the better part of 165 million years. Compare that with a measly 56 million years of primate activity. We bow to our evolutionary overlords in this episode.   Our conversation about these thunderous lizards roams freely as we talk with the paleontologist who discovered Dreadnoughtus - the largest land lizard unearthed to date.  Kenneth Lacovara asks that we please stop using the term "dinosaur" to refer to something outmoded, when in fact the dinos were among the most well-adapted, long-lived creatures ever. Plus, intriguing dino facts: if you like eating chicken, you like eating dinosaurs, and how T-Rex's puny arms helped him survive.  Also, with dozens of new species unearthed every year - nearly one a week - why we've entered the golden age of dinosaur discovery. Guest: Kenneth Lacovara- Paleontologist who unearthed the largest land dinosaur known: Dreadnoughtus.  He is also founding dean of the School of Earth and Environment at Rowan University, director of the Jean and Ric Edelman Fossil Park, and author of "Why Dinosaurs Matter."  


Skeptic Check: Flat Earth
2018-06-11 07:54:54
The Earth is not round.  Technically, it's an oblate spheroid.  But for some people, the first statement is not even approximately correct.  Flat Earthers believe that our planet resembles - not a slightly squashed grapefruit - but a thick pancake.   A journalist who covered a Flat Earth convention describes the rationale behind this ever-more popular belief.  So how do you establish science truth?  We look at the difference between a truly scientific examination of extraordinary claims and approaches that feel and look science-y but aren't.   Find out how one man will use telescopes and balloons in the desert to demonstrate that the Earth is a globe, while a biologist runs a test on the waters of Loch Ness to see if it contains prehistoric reptile DNA. And what happens when amateur investigators chase ghosts, UFOs, and Bigfoot with science instruments, but without an understanding of the scientific method. Guests: James Underdown- Executive Director of the Center for Inquiry in Los Angeles and of the Independent Investigations Group. The results of his experiment will be posted here. Alex Moshakis- Journalist who writes for the Observer, the Guardian, and Esquire.  His article on the U.K.'s first Flat Earth convention appeared in May, 2018 in the     Harry Dyer-  Lecturer in education at the University of East Anglia.  His article about the flat earth convention is titled "I Watched an Entire Flat Earth Convention for my Research, Here is What I Learned." Neil Gemmell- Professor in the Department of Anatomy, University of Otago, New Zealand Sharon Hill- Geologist, science writer, speaker, and author of "Scientifical Americans: The Culture of Amateur Paranormal Researchers."


Imagining Planets
2018-06-04 08:27:34
Pluto, we hardly knew ye.  Well, not anymore!  Until recently, Pluto and Mars were respectively the least-known and best-known planet-sized bodies in our Solar System.  Thanks to the New Horizons spacecraft, our picture of Pluto has changed from a featureless dot to a place where we can name the geologic features.  And with rovers and orbiters surveying the red planet, we now know much more about Mars than our parents ever did.  Examining our planetary backyard has provided insight into the trillion other planets in our galaxy. Dive into a mountain lake and trek though the driest desert on Earth with a scientist who's had not one but two near-fatal incidents in these extreme environments. Find out what questions compel her to keep returning. And scientists on the New Horizons mission remember why the nail-biting Pluto flyby almost failed at the last minute. Find out what surprises Pluto offered and what the mission might uncover as it heads to its next, outer solar-system target. Also, from Earth-like planets to super Earths and water worlds: a tour of some of Kepler's most intriguing extrasolar planets. Guests: Nathalie Cabrol- Planetary scientist at the SETI Institute. Alan Stern- Principal Investigator for NASA's New Horizon mission, and co-author with David Grinspoon of "Chasing New Horizons: Inside the Epic First Mission to Pluto." David Grinspoon- Senior scientist at the Planetary Science Institute, and co-author with Alan Stern of "Chasing New Horizons: Inside the Epic First Mission to Pluto." Jack Lissauer- Space scientist at the NASA Ames Research Center.


You Are Exposed
2018-05-14 07:47:56
There's no place like "ome."  Your microbiome is highly influential in determining your health.  But it's not the only "ome" doing so.  Your exposome - environmental exposure over a lifetime - also plays a role. Hear how scientists hope to calculate your entire exposome, from food to air pollution to water contamination. Plus, new research on the role that microbes play in the development of neurological diseases such as Parkinson's, and the hot debate about when microbes first colonize the body.  Could a fetus have its own microbiome? Also, choose your friends wisely: studies of microbe-swapping gazelles reveal the benefits - and the downsides - of being social. And, why sensors on future toilets will let you do microbiome analysis with every flush. Guests: Rob Knight - Professor of Pediatrics, Computer Science and Engineering, and Director of the Center for Microbiome Innovation at the University of California, San Diego Vanessa Ezenwa - Ecologist at the University of Georgia Indira Mysorekar - Microbiologist at Washington University in St. Louis, Missouri Gary Miller - Professor of public health at the Rollins School of Public Health and director of the HERCULES Exposome Research Center at Emory University. After August 2018, his lab will be at Columbia University.


We Are VR
2018-05-07 06:10:29
Will virtual reality make you a better person?  It's been touted as the "ultimate empathy machine," and one that will connect people who are otherwise emotionally and physically isolated.  The promise of the technology has come a long way since BiPiSci last took a VR tour.  Find out why researchers say virtual reality is no longer an exclusive club for gamers, but a powerful tool to build community. Seth puts on a VR headset for an immersive experience of a man who's evicted from his apartment.  Find out why researchers say the experience creates empathy and sparks activism to address homelessness. Also, why our spouses will love our avatars as much as they do us, the dark side of VR as a space for unchecked harassment, and consider: what if you're already living a simulation created by your brain? Guests: Peter Rubin - Editor for Wired, author of "Future Presence: How Virtual reality is Changing Human Connection, Intimacy, and the Limits of Ordinary Life" Jeremy Bailenson - Professor of Communication at Stanford University, founding director of the Virtual Human Interaction Lab, and author of "Experience on Demand: What Virtual Reality Is, How It Works, and What It Can Do" Carolina Cruz-Neira - Director of the Emerging Analytics Center at the University of Arkansas, Little Rock Thomas Metzinger - Philosopher of Mind and Cognitive Science, at Johannes Gutenberg University of Mainz, Germany


High Moon
2018-04-23 07:19:12
"The moon or bust" is now officially bust.  No private company was able to meet the Lunar X Prize challenge, and arrange for a launch by the 2018 deadline.  The $30 million award goes unclaimed, but the race to the moon is still on. Find out who wants to go and why this is not your parents' - or grandparents' - space race. With or without a cash incentive, private companies are still eyeing our cratered companion, hoping to set hardware down on its dusty surface.  Meanwhile, while the U.S. waffles about a return to the moon, India and China are sending a second round of robots skyward.  And a proposed orbiting laboratory - the Lunar Orbital Platform-Gateway - may literally put scientists over, and around, the moon. The moon continues to entice sci-fi writers, and Andy Weir's new novel describes a vibrant lunar colony. Its premise of colonists launched from Kenya is not entirely fiction: the nation is one of many in Africa with space programs. Guests: Andy Weir - Author of "The Martian" and, most recently, "Artemis" Allen Herbert - Vice President of Business Development and Strategy for NanoRacks, LLC and author of an article about emerging space programs in Africa Greg Schmidt - Deputy director of the Solar System Exploration Research Virtual Institute at NASA Ames Research Center Jason Crusan - NASA Director of Advanced Exploration Systems for Human Space Flight


Skeptic Check: Political Scientist
2018-04-16 08:04:58
Hundreds of thousands of scientists took to the streets during the March for Science.  The divisive political climate has spurred some scientists to deeper political engagement - publicly challenging lawmakers and even running for office themselves.   But the scientist-slash-activist model itself is contested, even by some of their colleagues. Find out how science and politics have been historically intertwined, what motivates scientists to get involved, and the possible benefits and harm of doing so. Is objectivity damaged when scientists advocate? Plus, how Michael Mann became a reluctant activist, whether his "street fighter" approach is effective in defending climate science, and the price he and his family paid for speaking out. Also, how the organization 314 Action is helping a record number of scientists run for Congress.  But will the group support only Democratic contenders? Guests:                         Robert Young - Geologist, Western Carolina University Douglas Haynes - Historian of medicine and science, University of California, Irvine Michael Mann - Professor, atmospheric science, Director, Earth System Science Center, Penn State University Shaugnessy Naughton - Founder and President, 314 Action Alex Berezow - Senior fellow of biomedical science at the American Council on Science and Health


Hawkingravity
2018-04-02 05:27:43
Stephen Hawking felt gravity's pull.  His quest to understand this feeble force spanned his career, and he was the first to realize that black holes actually disappear - slowly losing the mass of everything they swallow in a dull, evaporative glow called Hawking radiation.  But one of gravity's deepest puzzles defied even his brilliant mind.  How can we connect theories of gravity on the large scale to what happens on the very small?  The Theory of Everything remains one of the great challenges to physicists. Also, the latest on deciphering the weirdness of black holes and why the gravitational wave detector LIGO has added colliding neutron stars to its roster of successes. Plus, a fellow physicist describes Dr. Hawking's extraordinary deductive abilities and what it was like to collaborate with him.  And, a surprise awaits Molly when she meets a local string theorist to discuss his search for the Theory of Everything. Guests: Leonard Mlodinow- physicist and author of "The Grand Design" with Stephen Hawking, and most recently, "Elastic: Flexible Thinking in a Time of Change."  Janna Levin- Physicist and astronomer, Barnard College, Columbia University, and the author of, "Black Hole Blues and Other Songs from Outer Space."  Richard Camuccio- Graduate research assistant at the University of Texas Rio Grande Valley Center for Gravitational Wave Astronomy, a LIGO collaborator.  Wahltyn Rattray - Grad-student, the University of Texas Rio Grande Valley Center for Gravitational Wave Astronomy. Raphael Bousso- Physicist, Berkeley Center for Theoretical Physics, University of California-Berkeley.   


The X-Flies
2018-03-19 07:50:08
Insect populations are declining.  But before you say "good riddance," consider that insects are the cornerstone of many ecosystems.  They are dinner for numerous animal species and are essential pollinators.   Mammals are loved, but they are not indispensable.  Insects are. Meanwhile, marvel at the extraordinary capabilities of some insects.  The zany aerial maneuvers of the fly are studied by pilots.  And, contrary to the bad press, cockroaches are very clean creatures.  Also, take a listen as we host some Madagascar hissing cockroaches in our studio (yes, they audibly hiss). Plus, how insects first evolved ... and the challenges in controlling lethal ones.  Are genetically-engineering mosquitoes the best way to combat malaria? Guests: Erica McAlister - Entomologist, Senior Curator of diptera in the Department of Entomology, Natural History Museum in London, author of "The Secret Life of Flies" Jessica Ware - Evolutionary biologist and entomologist at Rutgers University Anthony James - Vector biologist, University of California, Irvine Lauren Esposito - Arachnologist, California Academy of Sciences, San Francisco


Space: Why Go There?
2018-03-05 07:55:09
It takes a lot of energy and technology to leave terra firma. But why rocket into space when there's so much to be done on Earth?  From the practical usefulness of satellites to the thrill of exploring other worlds, let us count the ways. The launch of a NOAA weather satellite to join its twin provides unparalleled observation of storms, wildfires, and even lightning.  Find out what it's like to watch hurricanes form from space. Meanwhile, more than a dozen countries want their own satellites to help solve real-world problems, including tracking disease.  Learn how one woman is helping make space accessible to everyone. Plus, now that we've completed our grand tour of the Solar System, which bodies are targets for return missions and which for human exploration?   Guests: Sarah Cruddas - Space journalist, broadcaster, and author based in the U.K. Jamese Sims - GOES-R Project Manager at NOAA Danielle Wood - Assistant professor, MIT Media Lab, Director of the Space Enabled Research Group Jim Green - NASA Planetary Science Division Director 


Meet Your Robot Barista
2018-02-26 06:48:52
Move over Roomba.  Café robots are the latest in adorable automation. And they may be more than a fad. As robots and artificial intelligence enter the workforce, they could serve up more than machine-made macchiato.  Digital workers are in training to do a wide variety jobs. Will humans be handed the mother of all pink slips? We sip lattes in a robot café and contemplate the future of work. Some say the workplace will have more machines than people, while others maintain that A.I. will augment, not replace, human workers. Meanwhile, future intelligent automation may not come from Silicon Valley.  Why China wants to become the global center for A.I.    Plus, NASA's first bipedal humanoid robot - Valkyrie, a prototype of a construction worker for use on Mars - teaches us that moving like a human is not as easy as it looks. Guests: Martin Ford - Futurist who writes about the impact of robots and artificial intelligence on society; author of "The Rise of the Robots: Technology and the Threat of a Jobless Future" Peter Norvig - Director of research, Google Owen Churchill - Journalist; his article "China's AI dreams" appeared in Nature, January 18, 2018  Kimberly Hambuchen - Aeronautics engineer; the principal technologist of robotics at NASA's Johnson Space Center


Bacteria to the Future
2018-02-12 06:47:31
Why did the chicken take antibiotics?  To fatten it up and prevent bacterial infection. As a result, industrial farms have become superbug factories, threatening our life-saving antibiotics. Find out how our wonder drugs became bird feed, and how antibiotic resistant bugs bred on the farm end up on your dinner plate.  A journalist tells the story of the 1950s fad of "acronizing" poultry; the act of dipping it in an antibiotic bath so it can sit longer on a refrigerator shelf. Plus, some ways we can avoid a post-antibiotic era. The steps one farm took to make their chickens antibiotic free... and resurrecting an old therapy: enlisting viruses to target and destroy multi-drug resistant bacteria.  Set your "phages" to stun.  Guests: Maryn McKenna - Investigative journalist who specializes in public health and food policy. Author of "Big Chicken: The Incredible Story of How Antibiotics Created Modern Agriculture and Changed the Way the World Eats." Ryland Young - Biochemist, head of the Center for Phage Technology at Texas A&M University.


Creative Brains
2018-02-05 08:20:10
Your cat is smart, but its ability to choreograph a ballet or write computer code isn't great.  A lot of animals are industrious and clever, but humans are the only animal that is uniquely ingenious and creative.  Neuroscientist David Eagleman and composer Anthony Brandt discuss how human creativity has reshaped the world. Find out what is going on in your brain when you write a novel, paint a watercolor, or build a whatchamacallit in your garage. But is Homo sapiens' claim on creativity destined to be short-lived?  Why both Eagleman and Brandt are prepared to step aside when artificial intelligence can do their jobs. Guests: Anthony Brandt - Professor of Composition and Theory, Rice University, and co-author of "The Runaway Species: How Human Creativity Remakes the World" David Eagleman - Neuroscientist, Stanford University, and co-author, "The Runaway Species: How Human Creativity Remakes the World"


Skeptic Check: New UFO Evidence
2018-01-29 07:32:38
It was a shocker of a story, splashed across the New York Times front page: The existence of a five-year long, hidden Pentagon investigation of UFOs.  With one-third of the American public convinced that aliens are visiting Earth, could this study finally provide the proof? We consider how this story came to light and what the $22 million program has produced.  Does the existence of a secret study mean there's now decent proof of extraterrestrial craft in our skies?  We take a look at the evidence made public so far. And why, six years after the study ended, are we learning about it now? Guests: James Oberg - Space journalist, historian and former NASA employee James McGaha - Retired Air Force pilot, astronomer and director of the Grasslands Observatory Ben Radford - Deputy editor of Skeptical Inquirer magazine and a Research Fellow with the Committee for Skeptical Inquiry

We're told if the economy is growing, and if we keep producing, that's a good thing. But at what cost? This hour, TED speakers explore circular systems that regenerate and re-use what we already have. Guests include economist Kate Raworth, environmental activist Tristram Stuart, landscape architect Kate Orff, entrepreneur David Katz, and graphic designer Jessi Arrington.

#504 The Art of Logic
How can mathematics help us have better arguments? This week we spend the hour with "The Art of Logic in an Illogical World" author, mathematician Eugenia Cheng, as she makes her case that the logic of mathematics can combine with emotional resonance to allow us to have better debates and arguments. Along the way we learn a lot about rigorous logic using arguments you're probably having every day, while also learning a lot about our own underlying beliefs and assumptions.
