Investigation shows journal editors getting paid to publish bunk papers, and new techniques for finding tumor DNA in the blood
 
First up on this week’s episode, Frederik Joelving, an editor and reporter for the site Retraction Watch, talks with host Sarah Crespi about paper mills—organizations that sell authorship on research papers—that appear to be bribing journal editors to publish bogus articles. They talk about the drivers behind this activity and what publishers can do to stop it.
 
Next, producer Zakiya Whatley of the Dope Labs podcast talks with researcher Carmen Martin-Alonso, a graduate student in the Harvard–Massachusetts Institute of Technology Program in Health Sciences and Technology, about improving liquid biopsies for cancer. They discuss novel ways to detect tumor DNA circulating in the blood.

On this week’s show: What happens when the body’s own immune system attacks the brain, and how otters’ use of tools expands their diet
 
First on the show this week, when rogue antibodies attack the brain, patients can show bizarre symptoms—from extreme thirst, to sleep deprivation, to outright psychosis. Contributing Correspondent Richard Stone joins host Sarah Crespi to discuss the hunt for biomarkers and treatments for this cluster of autoimmune disorders that were once mistaken for schizophrenia or even demonic possession.
 
Next on this episode, producer Katherine Irving talks with Chris Law, an evolutionary biologist at the University of Washington and the University of Texas at Austin, about how sea otters gain energy benefits (and dental benefits) when they use tools to tackle tougher prey such as snails or large clams.

How the immune system can cause psychosis, and tool use in otters

Jupiter’s moon Io has likely been volcanically active since the start of the Solar System, and a proposal to safeguard healthy human subjects in clinical trials

First on the show this week, a look at proposed protections for healthy human subjects, particularly in phase 1 clinical trials. Deputy News Editor Martin Enserink joins host Sarah Crespi to discuss the risks healthy participants face when involved in early testing of drugs for safety and tolerance. Then, we hear about a project to establish a set of global standards initiated by the Ethics Committee of France’s national biomedical research agency, INSERM.
 
Next on this episode, a peek at the history of the most volcanically active body in the Solar System, Jupiter’s moon Io. Because the surface of Io is constantly being remodeled by its many volcanoes, it’s difficult to study its past by looking at craters or other landmarks. Katherine de Kleer, assistant professor of planetary science and astronomy at the California Institute of Technology, talks about using isotopic ratios in the moon’s atmosphere to estimate how long it’s been spewing matter into space.

A very volcanic moon, and better protections for human study subjects

Bringing historical seismic reports and modern seismic risk maps into alignment, and a roundup of stories from our newsletter, ScienceAdviser
 
First on the show this week, a roundup of stories with our newsletter editor, Christie Wilcox. Wilcox talks with host Sarah Crespi about the oldest ice ever found, how well conservation efforts seem to be working, and repelling mosquitoes with our skin microbes.
 
Next on this episode, evaluating seismic hazard maps. In a Science Advances paper this week, Leah Salditch, a geoscience peril adviser at risk and reinsurance company Guy Carpenter, compared modern seismic risk map predictions with descriptions of past quakes. The analysis found a mismatch: Reported shaking in the past tended to be stronger than modern models would have predicted. She talks with Crespi about where this bias comes from and how to fix it.

Improving earthquake risk maps, and the world’s oldest ice

Researchers try to identify effective loneliness interventions, making the Sandmeyer safer, and books that look to the future and don’t see doom and gloom
 
First up on the show, Deputy News Editor Kelly Servick explores the science of loneliness. Is loneliness on the rise or just our awareness of it? How do we deal with the stigma of being lonely?
 
Also appearing in this segment:
●     Laura Coll-Planas
●     Julianne Holt-Lunstad
●     Samia Akhter-Khan
 
Next, producer Ariana Remmel talks with Tim Schulte, a graduate student at the Max Planck Institute for Coal Research and RWTH Aachen University, about making one of organic chemistry’s oldest reactions—the Sandmeyer reaction—both safer and more versatile.
 
Finally, we kick off this year’s book series with books editor Valerie Thompson and books host Angela Saini. They discuss this year’s theme: a future to look forward to.
 
Book segments come out the last episode of the month. Books in the series:
●     Eve: The Disobedient Future of Birth by Claire Horn (May)
●     Tokens: The Future of Money in the Age of the Platform by Rachel O’Dwyer (June)
●     The Heart and the Chip: Our Bright Future with Robots by Daniela Rus and Gregory Mone (July)
●     Climate Capitalism: Winning the Race to Zero Emissions and Solving the Crisis of Our Age by Akshat Rathi (August)
●     Virtual You: How Building Your Digital Twin Will Revolutionize Medicine and Change Your Life by Peter Coveney and Roger Highfield (September)
●     Imagination: A Manifesto by Ruha Benjamin (October)

The science of loneliness, making one of organic chemistry’s oldest reactions safer, and a new book series

A different source of global warming, signs of a continentwide tradition of human sacrifice, and a virus that attacks the cholera bacteria
 
First up on the show this week, clearer skies might be accelerating global warming. Staff Writer Paul Voosen joins host Sarah Crespi to discuss how as air pollution is cleaned up, climate models need to consider the decrease in the planet’s reflectivity. Less reflectivity means Earth is absorbing more energy from the Sun and increased temps.
 
Also from the news team this week, we hear about how bones from across Europe suggest recurring Stone Age ritual killings. Contributing Correspondent Andrew Curry talks about how a method of murder used by the Italian Mafia today may have been used in sacrifices by early farmers, from Poland to the Iberian Peninsula.
 
Finally, Eric Nelson, an associate professor at the University of Florida’s Emerging Pathogens Institute, joins Sarah to talk about an infectious bacteria that’s fighting on two fronts. The bacterium that causes cholera—Vibrio cholerae—can be killed off with antibiotics but at the same time, it is hunted by a phage virus living inside the human gut. In a paper published in Science, Nelson and colleagues describe how we should think about phage as predator and bacteria as prey, in the savanna of our intestines. The ratio of predator to prey turns out to be important for the course of cholera infections.
