Earliest human footprints in North America, dating violins with tree rings, and the social life of DNA
Contributing Correspondent Lizzie Wade joins host Sarah Crespi to discuss fossilized footprints left on a lake shore in North America sometime before the end of Last Glacial Maximum—possibly the earliest evidence for humans on the continent. Read the research.
Next, Paolo Cherubini, a senior scientist in the dendrosciences research group at the Swiss Federal Institute for Forest, Snow and Landscape Research, discusses using tree rings to date and authenticate 17th and 18th century violins worth millions of dollars.
Finally, in this month’s installment of the series of book interviews on race and science, guest host Angela Saini interviews Alondra Nelson, professor in the School of Social Science at the Institute for Advanced Study, about her 2016 book The Social Life of DNA: Race, Reparations, and Reconciliation After the Genome.

Legions of lunar landers, and why we make robots that look like people
Staff Writer Paul Voosen talks with host Sarah Crespi about plans for NASA’s first visit to the Moon in 50 years—and the quick succession of missions that will likely follow.
Next, Eileen Roesler, a researcher and lecturer at the Technical University of Berlin in the field of human-robot automation, discusses the benefits of making robots that look and act like people—it’s not always as helpful as you would think.

Pinpointing the origins of SARS-CoV-2, and making vortex beams of atoms
Staff Writer Jon Cohen joins host Sarah Crespi to discuss the many theories circulating about the origins of SARS-CoV-2 and why finding the right one is important.
Next, Ed Narevicius, a professor in the chemical and biological physics department at the Weizmann Institute of Science, talks with Sarah about creating vortex beams of atoms—a quantum state in which the phase of the matter wave of an atom rotates around its path, like a spiral staircase.

New insights into endometriosis, predicting RNA folding, and the surprising career of the spirometer
News Intern Rachel Fritts talks with host Sarah Crespi about a new way to think about endometriosis—a painful condition found in one in 10 women in which tissue that normally lines the uterus grows on the outside of the uterus and can bind to other organs.
Next, Raphael Townshend, founder and CEO of Atomic AI, talks about predicting RNA folding using deep learning—a machine learning approach that relies on very few examples and limited data.
Finally, in this month's edition of our limited series on race and science, guest host and journalist Angela Saini is joined by author Lundy Braun, professor of pathology and laboratory medicine and Africana studies at Brown University, to discuss her book: Breathing Race into the Machine: The Surprising Career of the Spirometer from Plantation to Genetics.

Building a martian analog on Earth, and moral outrage on social media
Contributing Correspondent Michael Price joins host Sarah Crespi to discuss the newest Mars analog to be built on the location of the first attempt at a large-scale sealed habitat, Biosphere 2 in Arizona.
Next, William Brady, a postdoctoral researcher in the psychology department at Yale University, talks with Sarah about using an algorithm to measure increasing expressions of moral outrage on social media platforms.

A risky clinical trial design, and attacks on machine learning
Charles Piller, an investigative journalist for Science, talks with host Sarah Crespi about a risky trial of vitamin D in asthmatic children that has caused a lot of concern among ethicists. They also discuss how the vitamin D trial connects with a possibly dangerous push to compare new treatments with placebos instead of standard-of-care treatments in clinical trials.
Next, Birhanu Eshete, professor of computer and information science at the University of Michigan, Dearborn, talks with producer Joel Goldberg about the risks of exposing machine learning algorithms online—risks such as the reverse engineering of training data to access proprietary information or even patient data.

A freeze on prion research, and watching cement dry
International News Editor Martin Enserink talks with host Sarah Crespi about a moratorium on prion research after the fatal brain disease infected two lab workers in France, killing one.
Next, Abhay Goyal, a postdoctoral fellow at Georgetown University, talks with intern Claire Hogan about his Science Advances paper on figuring out how to reduce the massive carbon footprint of cement by looking at its molecular structure.
Finally, in a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders interviews Ansuman Satpathy, assistant professor in the department of pathology at Stanford University School of Medicine and 2018 winner of the Michelson Prize for Human Immunology and Vaccine Research, about the importance of supporting early-career research and diversity in science, technology, engineering, and math. This segment is sponsored by Michelson Philanthropies.

Debating healthy obesity, delaying type 1 diabetes, and visiting bone rooms
First this week, Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to discuss the paradox of metabolically healthy obesity. They chat about the latest research into the relationships between markers of metabolic health—such as glucose or cholesterol levels in the blood—and obesity. They aren’t as tied as you might think.
Next, Colin Dayan, professor of clinical diabetes and metabolism at Cardiff University and senior clinical researcher at the Wellcome Centre for Human Genetics at the University of Oxford, joins Sarah to discuss his contribution to a special issue on type 1 diabetes. In his review, Colin and colleagues lay out research into how type 1 diabetes can be detected early, delayed, and maybe even one day prevented.
Finally, in the first of a six-part series of book interviews on race and science, guest host Angela Saini talks with author and professor of history at the University of Massachusetts, Amherst, Samuel Redman, about his book Bone Rooms: From Scientific Racism to Human Prehistory in Museums. The two discuss the legacy of human bone collecting and racism in museums today.
