Science Senior Correspondent Daniel Clery regales host Sarah Crespi with tales about the most important work to come from 57 years of research at the now-defunct Arecibo Observatory and plans for the future of the site.

Sarah also talks with Toman Barsbai, an associate professor in the school of economics at the University of Bristol, about the influence of ecology on human behavior—can we figure out how many of our behaviors are related to the different environments where we live? Barsbai and colleagues took on this question by comparing behaviors around finding food, reproduction, and social hierarchy in three groups of animals living in the same places: foraging humans, nonhuman mammals, and birds.

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.

Ritual murders in the neolithic, why 2023 was so hot, and virus and bacteria battle in the gut

]Researchers are testing HIV drugs and monoclonal antibodies against long-lasting COVID-19, and what it takes to turn a symbiotic friend into an organelle
 
First up on the show this week, clinical trials of new and old treatments for Long Covid. Producer Meagan Cantwell is joined by Staff Writer Jennifer Couzin-Frankel and some of her sources to discuss the difficulties of studying and treating this debilitating disease.
 
People in this segment:
·      Michael Peluso
·      Sara Cherry
·      Shelley Hayden
 
Next: Move over mitochondria, a new organelle called the nitroplast is here. Host Sarah Crespi talks with Tyler Coale, a postdoctoral scholar in the University of California, Santa Cruz’s Ocean Sciences Department, about what exactly makes an organelle an organelle and why it would be nice to have inhouse nitrogen fixing in your cells.

Trialing treatments for Long Covid, and a new organelle appears on the scene

Tracing the arrival of rats using bones, isotopes, and a few shipwrecks; and what scientists have learned in 50 years about our famous ancestor Lucy
 
First on the show: Did rats come over with Christopher Columbus? It turns out, European colonists weren’t alone on their ships when they came to the Americas—they also brought black and brown rats to uninfested shores. Eric Guiry, a researcher in the Trent Environmental Archaeology Lab at Trent University, joins host Sarah Crespi to discuss how tiny slices of bone from early colony sites and sunken shipwrecks can tell us when these pesky rodents arrived.
 
Next, producer Meagan Cantwell talks with Contributing Correspondent Ann Gibbons about what has happened in the 50 years since anthropologists found Lucy—a likely human ancestor that lived 2.9 million to 3.3 million years ago. Although still likely part of our family tree, her place as a direct ancestor is in question. And over the years, her past has become less lonesome as it has become populated with other contemporaneous hominins.

When did rats come to the Americas, and was Lucy really our direct ancestor?

Robots that can smile in synchrony with people, and what ends up in the letters section

First on this week’s show, a robot that can predict your smile. Hod Lipson, a roboticist and professor at Columbia University, joins host Sarah Crespi to discuss how mirrors can help robots learn to make facial expressions and eventually improve robot nonverbal communication.
 
Next, we have Margaret Handley, a professor in the department of epidemiology and biostatistics and medicine at the University of California San Francisco. She shares a letter she wrote to Science about how her past, her family, and a rare instrument relate to her current career focus on public health and homelessness. Letters Editor Jennifer Sills also weighs in with the kinds of letters people write into the magazine.

Other Past as Prologue letters:
A new frontier for mi familia by Raven Delfina Otero-Symphony
