Making sure American Indian COVID-19 cases are counted, and feeding a hungry heart Oct 15, 2020

Show notes

First up, host Meagan Cantwell speaks with Abigail Echo-Hawk, director of the Urban Indian Health Institute and chief research officer for the Seattle Indian Health Board. Echo-Hawk shares what inspired her journey in public health and explains the repercussions of excluding native people from health data. This story was originally reported by Lizzie Wade, who profiled Echo-Hawk as part of Science’s “voices of the pandemic” series.

Next, host Sarah Crespi interviews Danielle Murashige, a Ph.D. student at the University of Pennsylvania, about her Science paper that attempts to quantify how much fuel a healthy heart needs.

Visiting a once-watery asteroid, and how buzzing the tongue can treat tinnitus Oct 08, 2020

Show notes

First up, Staff Writer Paul Voosen talks with host Sarah Crespi about the Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) mission to the asteroid Bennu. After OSIRIS-REx’s up-close surveys of the surface revealed fewer likely touchdown points than expected, its sampling mission has been rejiggered. Paul talks about the prospects for a safe sampling in mid-October and what we might learn when the craft returns to Earth in 2023.

Sarah also talks with Hubert Lim, from the University of Minnesota, Twin Cities, and Neuromod Devices Limited, about his Science Translational Medicine paper on a new treatment for tinnitus. The team showed that bimodal stimulation—playing sounds in the ear and buzzes on the tongue—was able to change the brain and turn down the tinnitus in a large clinical trial.

FDA clinical trial protection failures, and an AI that can beat curling’s top players Oct 01, 2020

Show notes

Investigative journalist Charles Piller joins host Sarah Crespi to discuss his latest Science exclusive: a deep dive into the Food and Drug Administration’s protection of human subjects in clinical trials. Based on months of data analysis and interviews, he uncovered long-term failures in safety enforcement in clinical trials and potential problems with trial data used to make decisions about drug and device approvals.

Sarah also talks with Klaus-Robert Müller, a professor of machine learning at the Technical University of Berlin, about an artificial intelligence (AI) trained in the sport of curling—often described as a cross between bowling and chess. Although AI has succeeded in chess, Go, and poker, the constantly changing environment of curling is far harder for a nonhuman mind to adapt to. But AIs were the big winners in competitions with top human players, Müller and colleagues report this week in Science Robotics.

How Neanderthals got human Y chromosomes, and the earliest human footprints in Arabia Sep 24, 2020

Show notes

Contributing Correspondent Ann Gibbons talks with host Sarah Crespi about a series of 120,000-year-old human footprints found alongside prints from animals like asses, elephants, and camels in a dried-up lake on the Arabian Peninsula. These are the earliest human footprints found so far in Arabia and may help researchers better understand the history of early hominin migrations out of Africa.

Continuing on the history of humanity theme, Sarah talks with Janet Kelso of the Max Planck Institute for Evolutionary Anthropology, about her team’s efforts to fish the elusive Y chromosome out of Neanderthal and Denisovan DNA. It turns out Y chromosomes tell a different story about our past interbreeding with Neanderthals than previous tales told by the rest of the genome. Read a related Insight article.

Performing magic for animals, and why the pandemic is pushing people out of prisons Sep 17, 2020

Show notes

Staff Writer Kelly Servick joins host Sarah Crespi to discuss how jail and prison populations in the United States have dropped in the face of coronavirus and what kinds of scientific questions about public health and criminal justice are arising as a result.

Also this week, Elias García-Pelegrín, a Ph.D. student at the University of Cambridge, talks with Sarah about his article on watching animals watch magic tricks. Do animals fall for the same illusions we do? What does it say about the way their minds work?

Alien hunters get a funding boost, and checking on the link between chromosome ‘caps’ and aging Sep 10, 2020

Show notes

First up this week, Senior Correspondent Daniel Clery talks with host Sarah Crespi about how Breakthrough Listen—a privately funded initiative that aims to spend $100 million over 10 years to find extraterrestrial intelligent life—has changed the hunt for alien intelligence-link.

And as part of a special issue on the Genotype-Tissue Expression (GTEx) Project, Brandon Pierce, a professor in the Departments of Public Health Sciences and Human Genetics at the University of Chicago, joins Sarah to discuss his group’s work on variation in the protective caps at the end of our chromosomes. The gradual shortening of these caps, also known as telomeres, has been associated with aging.

Fighting Europe’s second wave of COVID-19, and making democracy work for poor people Sep 03, 2020

Show notes

First up this week, Contributing Correspondent Kai Kupferschmidt talks with host Sarah Crespi about rising numbers of coronavirus cases in Europe. Will what we’ve learned this summer about how the virus is transmitted and treated help prevent a second peak?

And as part of a special issue on democracy, Rohini Pande, a professor in the department of economics at Yale University, joins Sarah to discuss her review that asks the question: Can democracy work for poor people? Read more from the special issue on democracy.

Arctic sea ice under attack, and ancient records that can predict the future effects of climate change Aug 27, 2020

Show notes

Staff Writer Paul Voosen talks with host Sarah Crespi about how Arctic sea ice is under attack from above and below—not only from warming air, but also dangerous hot blobs of ocean water.

Next, Damien Fordham, a professor and global change ecologist at the University of Adelaide, talks about how new tools for digging into the past are helping catalog what happened to biodiversity and ecosystems during different climate change scenarios in the past. These findings can help predict the fate of modern ecosystems under today’s human-induced climate change.

And in our books segment, Kiki Sanford talks with author Carl Bergstrom about his new book: Calling Bullshit: The Art of Skepticism in a Data-Driven World.

Wildlife behavior during a global lockdown, and electric mud microbes Aug 20, 2020

Show notes

First up this week, Staff Writer Erik Stokstad joins host Sarah Crespi to talk about how wildlife biologists are taking advantage of humanity’s sudden lull. Scientists are launching studies of everything from sea turtles on suddenly quiet beaches to noise-averse birds living near airports to see how animal behavior changes when people are a little less obtrusive.

Next, as part of our special issue on mud—yes, wet dirt— Senior Correspondent Elizabeth Pennisi talks about her story on electric microbes that were first found in mud and are now found pretty much everywhere. Why do bacteria need to move electrons around and what does it mean that they do it all over the planet?

A call for quick coronavirus testing, and building bonds with sports Aug 13, 2020

Show notes

Staff Writer Robert Service talks with host Sarah Crespi about a different approach to COVID-19 testing that might be useful in response to the high numbers of cases in the United States. To break chains of transmission and community spread, the new strategy would replace highly accurate but slow polymerase chain reaction (PCR) tests with cheaper, faster tests that are less accurate but can be administered frequently. Such tests cost between $1 and $3 compared with more than $100 for diagnostic PCR tests and give results in less than 30 minutes instead of days.

Also this week, Salma Mousa, a postdoctoral fellow at Stanford University, joins Sarah to talk about an experiment that added Muslim players to teams in a Christian soccer league in northern Iraq. The goal of the study was to see whether this type of social contact would change how the Christians—a threatened minority in the region—behaved toward Muslims, on and off the field.
