About 8000 years ago, people were drawing dogs with leashes, according to a series of newly described stone carvings from Saudi Arabia. Online News Editor David Grimm talks with Sarah Crespi about reporting on this story and what it says about the history of dog domestication. Sarah also interviews physicist Brad Marston of Brown University on surprising findings that bring together planetary science and quantum physics. It turns out that Earth’s rotation and the presence of oceans and atmosphere on its surface mean it can be described as a “topological insulator”—a term usually reserved for quantum phenomena. Insights from the study of these effects at the quantum level may help us understand weather and currents at the planetary level—including insights into climate change and exoplanets. Listen to previous podcasts.

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.

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.

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.

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.

Strawberries had both male and female parts, like most plants, until several million years ago. This may seem like a long time ago, but it actually means strawberries have some of the youngest sex chromosomes around. What are the advantages of splitting a species into two sexes? Host Sarah Crespi interviews freelance journalist Carol Cruzan Morton about her story on scientists’ journey to understanding the strawberry’s sexual awakening. In 2016, experimental Zika vaccines were swiftly developed in response to the emergence of serious birth defects in the babies of infected woman. Two years after the height of Zika cases, there’s so little spread of the virus in the Americas that it has stymied vaccine trials. Researchers hope to overcome this hurdle with “human challenge experiments”—vaccinating people, then intentionally infecting them with Zika to see whether they’re protected from the virus. Meagan Cantwell talks with staff writer Jon Cohen about his news story that highlights the risks and rewards of human challenge experiments. This week’s episode was edited by Podigy.

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.

As you age, your cells divide over and over again, leading to minute changes in their genomes. New research reveals that in the lining of the esophagus, mutant cells run rampant, fighting for dominance over normal cells. But they do this without causing any detectable damage or cancer. Host Sarah Crespi talks to Phil Jones, a professor of cancer development at the University of Cambridge in the United Kingdom, about what these genome changes can tell us about aging and cancer, and how some of the mutations might be good for you. Most Western farmers apply their pesticides using drones and machinery, but in less developed countries, organophosphate pesticides are applied by hand, resulting in myriad health issues from direct exposure to these neurotoxic chemicals. Host Meagan Cantwell speaks with Praveen Vemula, a research investigator at the Institute for Stem Cell Biology and Regenerative Medicine in Bengaluru, India, about his latest solution—a cost-effective gel that can be applied to the skin to limit pesticide-related toxicity and mortality.

The “dank” smelling terpenes emitted by growing marijuana can combine with chemicals in car emissions to form ozone, a health-damaging compound. This is especially problematic in Denver, where ozone levels are dangerously high and pot farms have sprung up along two highways in the city. Host Sarah Crespi talks with reporter Jason Plautz about researchers’ efforts to measure terpene emissions from pot plants and how federal restrictions have hampered them. Next, host Meagan Cantwell talks with Dana Small, a professor of psychiatry and psychology at Yale University, about how processed foods are perceived by the body. In a doughnut-rich world, what’s a body to think about calories, nutrition, and satiety? And in the first book segment of the year, books editor Valerie Thompson is joined by Erika Malim, a history professor at Princeton University, to talk about her book Creatures of Cain: The Hunt for Human Nature in Cold War America, which follows the rise and fall of the “killer ape hypothesis”—the idea that our capacity for killing each other is what makes us human.

Can we inherit trauma from our ancestors? Studies of behavior and biomarkers have suggested the stress of harsh conditions or family separations can be passed down, even beyond one’s children. Journalist Andrew Curry joins host Sarah Crespi to discuss a possible mechanism for this mode of inheritance and mouse studies that suggest possible ways to reverse the effects. Spiky, pulsating ferrofluids are perpetual YouTube stars. The secret to these dark liquid dances is the manipulation of magnetic nanoparticles in the liquid by external magnets. But when those outside forces are removed, the dance ends. Now, researchers writing in Science have created permanently magnetic fluids that respond to other magnets, electricity, and pH by changing shape, moving, and—yes—probably even dancing. Sarah Crespi talks to Thomas Russell of the University of Massachusetts in Amherst about the about the applications of these squishy, responsive magnets. This week’s episode was edited by Podigy.
