Ancient volcanic eruptions, and peer pressure—from robots
19:44
Several thousand years ago the volcano under Santorini in Greece—known as Thera—erupted in a tremendous explosion, dusting the nearby Mediterranean civilizations of Crete and Egypt in a layer of white ash. This geological marker could be used to tie together many ancient historical events, but the estimated date could be off by a century. Contributing Correspondent Lizzie Wade joins host Sarah Crespi to talk about a new study that used tree rings to calibrate radiocarbon readings—and get closer to pinning down a date. The findings also suggest that scientists may need to change their standard radiocarbon dating calibration curve. Sarah also talks to Tony Belpaeme of Ghent University in Belgium and Plymouth University in the United Kingdom about his Science Robotics paper that explored whether people are susceptible to peer pressure from robots. Using a classic psychological measure of peer influence, the team found that kids from ages 7 to 9 occasionally gave in to social pressure from robot peers, but adults did not.

Doubts about the drought that kicked off our latest geological age, and a faceoff between stink bugs with samurai wasps
20:12
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.

How our brains may have evolved for language, and clues to what makes us leaders—or followers
25:28
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.

Liquid water on Mars, athletic performance in transgender women, and the lost colony of Roanoke
25:40
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. Next month’s book will be The Book of Why: The New Science of Cause and Effect by Judea Pearl and Dana Mackenzie.

Why the platypus gave up suckling, and how gravity waves clear clouds
16:54
Suckling mothers milk is a pretty basic feature of being a mammal. Humans do it. Possums do it. But monotremes such as the platypus and echidna—although still mammals—gave up suckling long ago. Instead, they lap at milky patches on their mothers’ skin to get early sustenance. Science News Writer Gretchen Vogel talks with host Sarah Crespi about the newest suckling science—it turns out monotremes probably had suckling ancestors, but gave it up for the ability to grind up tasty, hard-shelled, river-dwelling creatures. Sarah also talks with Sandra Yuter of North Carolina State University in Raleigh about her work on fast-clearing clouds off the southwest coast of Africa. These immense marine layers appear to be exiting the coastal regions under the influence of gravity waves (not to be confused with gravitational waves). This finding can help scientists better model cloud behavior, particularly with respect to their influence on global temperatures. This week’s episode was edited by Podigy.

The South Pole’s IceCube detector catches a ghostly particle from deep space, and how rice knows to grow when submerged
24:55
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. How do these plants know they are submerged and how much to grow? Sarah and Susan discuss the mechanisms involved and where they originated. This week’s episode was edited by Podigy.

A polio outbreak threatens global eradication plans, and what happened to America’s first dogs
17:58
Wild polio has been hunted to near extinction in a decades-old global eradication program. Now, a vaccine-derived outbreak in the Democratic Republic of the Congo (DRC) is threatening to seriously extend the polio eradication endgame. Deputy News Editor Leslie Roberts joins host Sarah Crespi to talk about the tough choices experts face in the fight against this disease in the DRC. Sarah also talks with Online News Editor David Grimm about when dogs first came to the Americas. New DNA and archaeological evidence suggest these pups did not arise from North American wolves but came over thousands of years after the first people did. Now that we know where they came from, the question is: Where did they go? Read the research. This week’s episode was edited by Podigy. Listen to previous podcasts.

Increasing transparency in animal research to sway public opinion, and a reaching a plateau in human mortality
32:21
Public opinion on the morality of animal research is on the downswing in the United States. But some researchers think letting the public know more about how animals are used in experiments might turn things around. Online News Editor David Grimm joins Sarah Crespi to talk about these efforts. Sarah also talks Ken Wachter of the University of California, Berkeley about his group’s careful analysis of data from all living Italians born 105 or more years before the study. It turns out the risk of dying does not continue to accelerate with age, but actually plateaus around the age of 105. What does this mean for attempts to increase human lifespan? In this month’s book segment, Jen Golbeck talks with Simon Winchester about his book The Perfectionists: How Precision Engineers Created the Modern World.

New evidence in Cuba’s ‘sonic attacks,’ and finding an extinct gibbon—in a royal Chinese tomb
19:17
Since the 2016 reports of a mysterious assault on U.S. embassy staff in Cuba, researchers have struggled to find evidence of injury or weapon. Now, new research has discovered inner-ear damage in some of the personnel complaining of symptoms. Former International News Editor Rich Stone talks to host Sarah Crespi about the case, including new reports of a similar incident in China, and what kind of weapon—if any—might have been involved. Sarah also talks with Staff Writer Gretchen Vogel about the bones of an extinct gibbon found in a 2200- to 2300-year-old tomb in China. Although gibbons were often featured in historical poetry and paintings, these bones confirm their presence and the fact that they were distinct from today’s species.   Read the research.

The places where HIV shows no sign of ending, and the parts of the human brain that are bigger—in bigger brains
23:25
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.  This week’s episode was edited by Podigy.

Science books for summer, and a blood test for predicting preterm birth
18:25
What book are you taking to the beach or the field this summer? Science’s books editor Valerie Thompson and host Sarah Crespi discuss a selection of science books that will have you catching comets and swimming with the fishes. Sarah also talks with Mira Moufarrej of Stanford University in Palo Alto, California, about her team’s work on a new blood test that analyzes RNA from maternal blood to determine the gestational age of a fetus. This new approach may also help predict the risk of preterm birth. This week’s episode was edited by Podigy. Listen to previous podcasts. [Image: William Warby/Flickr; Music: Jeffrey Cook]

The first midsize black holes, and the environmental impact of global food production
18:34
Astronomers have been able to detect supermassive black holes and teeny-weeny black holes but the midsize ones have been elusive. Now, researchers have scanned through archives looking for middle-size galaxies and found traces of these missing middlers. Host Sarah Crespi and Staff Writer Daniel Clery discuss why they were so hard to find in the first place, and what it means for our understanding of black hole formation. Farming animals and plants for human consumption is a massive operation with a big effect on the planet. A new research project that calculated the environmental impact of global food production shows highly variable results for different foods—and for the same foods grown in different locations. Sarah talks with one of the researchers—Joseph Poore of the University of Oxford in the United Kingdom—about how understanding this diversity can help cut down food production’s environmental footprint and help consumers make better choices.

Sketching suspects with DNA, and using light to find Zika-infected mosquitoes
27:59
DNA fingerprinting has been used to link people to crimes for decades, by matching DNA from a crime scene to DNA extracted from a suspect. Now, investigators are using other parts of the genome—such as markers for hair and eye color—to help rule people in and out as suspects. Staff Writer Gretchen Vogel talks with Sarah Crespi about whether science supports this approach and how different countries are dealing with this new type of evidence. Sarah also talks with Jill Fernandes of the University of Queensland in Brisbane, Australia, about her Science Advances paper on a light-based technique for detecting Zika in mosquitoes. Instead of grinding up the bug and extracting Zika DNA, her group shines near-infrared light through the body. Mosquitoes carrying Zika transmit this light differently from uninfected ones. If it’s successful in larger trials, this technique could make large-scale surveillance of infected mosquitoes quicker and less expensive. In our monthly books segment, Jen Golbeck talks with author Sarah-Jayne Blakemore about her new work: Inventing Ourselves: The Secret Life of the Teenage Brain. You can check out more book reviews and share your thoughts on the Books et al. blog. This week’s episode was edited by Podigy. Listen to previous podcasts.

Tracking ancient Rome’s rise using Greenland’s ice, and fighting fungicide resistance
27:06
Two thousand years ago, ancient Romans were pumping lead into the air as they smelted ores to make the silvery coin of the realm. Online News Editor David Grimm talks to Sarah Crespi about how the pollution of ice in Greenland from this process provides a detailed 1900-year record of Roman history. This week is also resistance week at Science—where researchers explore the global challenges of antibiotic resistance, pesticide resistance, herbicide resistance, and fungicide resistance. Sarah talks with Sarah Gurr of the University of Exeter in the United Kingdom about her group’s work on the spread of antifungal resistance and what it means for crops and in the clinic. And in a bonus books segment, staff writer Jennifer Couzin-Frankel talks about medicine and fraud in her review of Bad Blood: Secrets and Lies in a Silicon Valley Startup by John Carreyrou.

Ancient DNA is helping find the first horse tamers, and a single gene is spawning a fierce debate in salmon conservation
17:40
Who were the first horse tamers? Online News Editor Catherine Matacic talks to Sarah Crespi about a new study that brings genomics to bear on the question. The hunt for the original equine domesticators has focused on Bronze Age people living on the Eurasian steppe. Now, an ancient DNA analysis bolsters the idea that a small group of hunter-gatherers, called the Botai, were likely the first to harness horses, not the famous Yamnaya pastoralists often thought to be the originators of the Indo-European language family. Sarah also talks with News Intern Katie Langin about her feature story on a single salmon gene that may separate spring- and fall-run salmon. Conservationists, regulators, and citizens are fiercely debating the role such a small bit of DNA plays in defining distinct populations. Is the spring run distinct enough to warrant protection?

The twins climbing Mount Everest for science, and the fractal nature of human bone
25:02
To study the biological differences brought on by space travel, NASA sent one twin into space and kept another on Earth in 2015. Now, researchers from that project are trying to replicate that work planet-side to see whether the differences in gene expression were due to extreme stress or were specific to being in space. Sarah Crespi talks with Online News Editor Catherine Matacic about a “control” study using what might be a comparably stressful experience here on Earth: climbing Mount Everest. Catherine also shares a recent study that confirmed what one reddit user posted 5 years ago: A single path stretching from southern Pakistan to northeastern Russia will take you on the longest straight-line journey on Earth, via the ocean. Finally, Sarah talks with Roland Kröger of the University of York in the United Kingdom about his group’s study published this week in Science. Using a combination of techniques usually reserved for materials science, the group explored the nanoscale arrangement of mineral in bone, looking for an explanation of the tissue’s contradictory combination of toughness and hardness.

Deciphering talking drums, and squeezing more juice out of solar panels
29:11
Researchers have found new clues to how the “talking drums” of one Amazonian tribe convey their messages. Sarah Crespi talks with Online News Editor Catherine Matacic about the role of tone and rhythm in this form of communication. Getting poked with a needle will probably get you moving. Apparently, it also gets charges moving in certain semiconductive materials. Sarah interviews Marin Alexe of The University of Warwick in Coventry, U.K., about this newfound flexo-photovoltaic effect. Alexe’s group found that prodding or denting certain semiconductors with tiny needles causes them to suddenly produce current in response to light. That discovery could enhance the efficiency of current of solar cell technologies. Finally, in our books segment, Jen Golbeck interviews Lucy Cooke about her new book The Truth About Animals: Stoned Sloths, Lovelorn Hippos, and Other Tales from the Wild Side of Wildlife.

Drug use in the ancient world, and what will happen to plants as carbon dioxide levels increase
23:30
Armed with new data, archaeologists are revealing that mind-altering drugs were present at the dawn of the first complex societies some 5000 years ago in the ancient Middle East. Contributing writer Andrew Lawler joins Sarah Crespi to discuss the evidence for these drugs and how they might have impacted early societies and beliefs. Sarah also interviews Sarah Hobbie of the University of Minnesota about the fate of plants under climate change. Will all that extra carbon dioxide in the air be good for certain types of flora? A 20-year long study published this week in Science suggests theoretical predictions have been off the mark. This week’s episode was edited by Podigy. Listen to previous podcasts.

How DNA is revealing Latin America’s lost histories, and how to make a molecule from just two atoms
20:59
Geneticists and anthropologists studying historical records and modern-day genomes are finding traces of previously unknown migrants to Latin America in the 16th and 17th centuries, when Asians, Africans, and Europeans first met indigenous Latin Americans. Sarah Crespi talks with contributing correspondent Lizzie Wade about what she learned on the topic at the American Association of Physical Anthropologists’s annual meeting in Austin. Sarah also interviews Kang-Keun Ni about her research using optical tweezers to bring two atoms—one cesium and one sodium—together into a single molecule. Such precise control of molecule formation is allowing new observations of these basic processes and is opening the door to creating new molecules for quantum computing.

Legendary Viking crystals, and how to put an octopus to sleep
20:27
A millennium ago, Viking navigators may have used crystals known as “sunstones” to navigate between Norway and Greenland. Sarah Crespi talks with Online News Editor David Grimm about how one might use a crystal to figure out where they are. Sarah also interviews freelancer Danna Staaf about her piece on sedating cephalopods. Until recently, researchers working with octopuses and squids faced the dilemma of not knowing whether the animals were truly sedated or whether only their ability to respond had been suppressed.

Chimpanzee retirement gains momentum, and x-ray ‘ghost images’ could cut radiation doses
29:45
Two of the world’s most famous research chimpanzees have finally retired. Hercules and Leo arrived at a chimp sanctuary in Georgia last week. Sarah Crespi checks in with Online News Editor David Grimm on the increasing momentum for research chimp retirement since the primates were labeled endangered species in 2015. Sarah also interviews freelancer Sophia Chen about her piece on x-ray ghost imaging—a technique that may lead to safer medical imaging done with cheap, single-pixel cameras. David Malakoff joins Sarah to talk about the big boost in U.S. science funding signed into law over the weekend. Finally, Jen Golbeck interviews author Stephanie Elizabeth Mohr on her book First in Fly: Drosophila Research and Biological Discovery for our monthly books segment.

A possible cause for severe morning sickness, and linking mouse moms’ caretaking to brain changes in baby mice
20:15
Researchers are converging on which genes are linked to morning sickness—the nausea and vomiting associated with pregnancy—and the more severe form: hyperemesis gravidarum (HG). And once we know what those genes are—can we help pregnant women feel better? News intern Roni Dengler joins Sarah Crespi to talk about a new study that suggests a protein already flagged for its role in cancer-related nausea may also be behind HG. In a second segment, Tracy Bedrosian of the Neurotechnology Innovations Translator talks about how the amount of time spent being licked by mom might be linked to changes in the genetic code of hippocampal neurons in mice pups. Could these types of genomic changes be a new type of plasticity in the brain? This week’s episode was edited by Podigy. Listen to previous podcasts. [Image: Jacob Bøtter/Flickr; Music: Jeffrey Cook]

How humans survived an ancient volcanic winter and how disgust shapes ecosystems
20:14
When Indonesia’s Mount Toba blew its top some 74,000 years ago, an apocalyptic scenario ensued: Tons of ash and debris entered the atmosphere, coating the planet in ash for 2 weeks straight and sending global temperatures plummeting. Despite the worldwide destruction, humans survived. Sarah Crespi talks with Online News Editor Catherine Matacic about how life after Toba was even possible—were humans decimated, or did they rally in the face of a suddenly extra hostile planet? Next, Julia Buck of the University of California, Santa Barbara, joins Sarah to discuss her Science commentary piece on landscapes of disgust. You may have heard of a landscape of fear—how a predator can influence an ecosystem not just by eating its prey, but also by introducing fear into the system, changing the behavior of many organisms. Buck and colleagues write about how disgust can operate in a similar way: Animals protect themselves from parasites and infection by avoiding disgusting things such as dead animals of the same species or those with disease.

Animals that don’t need people to be domesticated; the astonishing spread of false news; and links between gender, sexual orientation, and speech
40:12
Did people domesticate animals? Or did they domesticate themselves? Online News Editor David Grimm talks with Sarah Crespi about a recent study that looked at self-domesticating mice. If they could go it alone, could cats or dogs have done the same in the distant past? Next, Sinan Aral of the Massachusetts Institute of Technology in Cambridge joins Sarah to discuss his work on true and false rumor cascades across all of Twitter, since its inception. He finds that false news travels further, deeper, and faster than true news, regardless of the source of the tweet, the kind of news it was, or whether bots were involved. In a bonus segment recording during a live podcasting event at the AAAS Annual Meeting in Austin, Sarah first speaks with Ben Munson of the University of Minnesota in Minneapolis about markers of gender and sexual orientation in spoken language and then Adrienne Hancock of The George Washington University in Washington, D.C., talks about using what we know about gender and communication to help transgender women change their speech and communication style. Live recordings sessions at the AAAS meeting were supported by funds from the European Commission. This week’s episode was edited by Podigy. Listen to previous podcasts.

A new dark matter signal from the early universe, massive family trees, and how we might respond to alien contact
34:23
For some time after the big bang there were no stars. Researchers are now looking at cosmic dawn—the time when stars first popped into being—and are seeing hints of dark matter’s influence on supercold hydrogen clouds. News Writer Adrian Cho talks with Sarah Crespi about how this observation was made and what it means for our understanding of dark matter. Sarah also interviews Joanna Kaplanis of the Wellcome Sanger Institute in Hinxton, U.K., about constructing enormous family trees based on an online social genealogy platform. What can we learn from the biggest family tree ever built—with 13 million members spanning 11 generations? In a bonus segment recording during a live podcasting event at the AAAS Annual Meeting in Austin, Sarah talks with Michael Varnum of Arizona State University in Tempe about what people think they will do if humanity comes into contact with aliens that just happen to be microbes. Live recordings sessions at the AAAS meeting were supported by funds from the European Commission. This week’s episode was edited by Podigy. Listen to previous podcasts.

Neandertals that made art, live news from the AAAS Annual Meeting, and the emotional experience of being a scientist
23:56
We talk about the techniques of painting sleuths, how to combat alternative facts or “fake news,” and using audio signposts to keep birds from flying into buildings. For this segment, David Grimm—online news editor for Science—talks with host Sarah Crespi as part of a live podcast event from the AAAS Annual Meeting in Austin. Sarah also interviews Science News Editor Tim Appenzeller about Neandertal art. The unexpected age of some European cave paintings is causing experts to rethink the mental capabilities of our extinct cousins. For the monthly books segment, Jen Golbeck interviews with William Glassley about his book, A Wilder Time: Notes from a Geologist at the Edge of the Greenland Ice. Listen to previous podcasts.

Genes that turn off after death, and debunking the sugar conspiracy
13:18
Some of our genes come alive after we die. David Grimm—online news editor for Science—talks with Sarah Crespi about which genes are active after death and what we can learn about time of death by looking at patterns of postmortem gene expression. Sarah also interviews David Merritt Johns of Columbia University about the so-called sugar conspiracy. Historical evidence suggests, despite recent media reports, it is unlikely that “big sugar” influenced U.S. nutrition policy and led to the low-fat diet fad of the ’80s and ’90s.

Happy lab animals may make better research subjects, and understanding the chemistry of the indoor environment
21:01
Would happy lab animals—rats, mice, even zebrafish—make for better experiments? David Grimm—online news editor for Science—talks with Sarah Crespi about the potential of treating lab animals more like us and making them more useful for science at the same time. Sarah also interviews Jon Abbatt of the University of Toronto in Canada about indoor chemistry. What is going on in the air inside buildings—how different is it from the outside? Researchers are bringing together the tools of outdoor chemistry and building sciences to understand what is happening in the air and on surfaces inside—where some of us spend 90% of our time.

Following 1000 people for decades to learn about the interplay of health, environment, and temperament, and investigating why naked mole rats don’t seem to age
18:15
David Grimm—online news editor for Science—talks with Sarah Crespi about the chance a naked mole rat could die at any one moment. Surprisingly, the probability a naked mole rat will die does not go up as it gets older. Researchers are looking at the biology of these fascinating animals for clues to their seeming lack of aging. Sarah also interviews freelancer Douglas Starr about his feature story on the Dunedin Multidisciplinary Health and Development Study—a comprehensive study of the lives of all the babies born in 1 year in a New Zealand hospital. Starr talks about the many insights that have come out of this work—including new understandings of criminality, drug addiction, and mental illness—and the research to be done in the future as the 1000-person cohort begins to enter its fifth decade.

The dangers of dismantling a geoengineered sun shield and the importance of genes we don’t inherit
22:09
Catherine Matacic—online news editor for Science—talks with Sarah Crespi about how geoengineering could reduce the harshest impacts of climate change, but make them even worse if it were ever turned off. Sarah also interviews Augustine Kong of the Big Data Institute at the University of Oxford in the United Kingdom about his Science paper on the role of noninherited “nurturing genes.” For example, educational attainment has a genetic component that may or may not be inherited. But having a parent with a predisposition for attainment still influences the child—even if those genes aren’t passed down. This shift to thinking about other people (and their genes) as the environment we live in complicates the age-old debate on nature versus nurture. Listen to previous podcasts.

Unearthed letters reveal changes in Fields Medal awards, and predicting crime with computers is no easy feat
23:59
Freelance science writer Michael Price talks with Sarah Crespi about recently revealed deliberations for a coveted mathematics prize: the Fields Medal. Unearthed letters suggest early award committees favored promise and youth over star power. Sarah also interviews Julia Dressel about her Science Advances paper on predicting recidivism—the likelihood that a criminal defendant will commit another crime. It turns out computers aren’t better than people at these types of predictions, in fact—both are correct only about 65% of the time.   Jen Golbeck interviews Paul Shapiro about his book, Clean Meat: How Growing Meat Without Animals Will Revolutionize Dinner and the World, in our monthly books segment.   Listen to previous podcasts.
