On this week’s show: The impact of war on science in Ukraine, and a conversation with Anthony Fauci as he prepares to step down

Some scientists in Ukraine have been risking their lives to protect scientific facilities, collections, and instruments amid the war. Contributing Correspondent Richard Stone traveled to Kharkiv and Chornobyl earlier this year to meet researchers living and working through the conflict. He spoke with host Sarah Crespi to share some of their stories.

Then we have a conversation with Anthony Fauci, who will be stepping down from his government roles this month after more than 50 years in public service. He shares his thoughts on the ongoing challenges of communicating about science and public health, combating misinformation, and his goals for the future with Science Editor-and-Chief Holden Thorp.

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
A uranium miner’s daughter by Tanya J. Gallegos
Embracing questions after my father’s murder by Jacquelyn J. Cragg
A family’s pride in educated daughters by Qura Tul Ain
One person’s trash: Another’s treasured education by Xiangkun Elvis Cao

Teaching robots to smile, and the effects of a rare mandolin on a scientist’s career

New clinical trials for treatments of an always fatal brain disease, and what happens with pests when a conventional and organic farm are neighbors
 
First up on this week’s show, a new treatment to stave off prion disease goes into clinical trials. Prions are misfolded proteins that clump together and chew holes in the brain. The misfolding can be switched on in a number of ways—including infection with a misfolded prion protein from an animal or person. Staff Writer Meredith Wadman talks with host Sarah Crespi about new potential treatments—from antisense nucleotides to small molecules that interfere with protein production—for these fatal neurodegenerative diseases.
 
Next on the show: Freelance producer Katherine Irving talks with Ashley Larsen, associate professor of agricultural and landscape ecology at the University of California, Santa Barbara, about the effects of organic farms on their neighbors. If there are lots of organic growers together, pesticide use goes down but conventional farms tend to use more pesticides when side by side with organic farms.
