Studying color vision in with children who gain sight later in life, joining a cancer trial doesn’t improve survival odds, and the first in our books series this year Lees meer
First on this week’s show, Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to discuss the pros and cons of participating in clinical trials. Her story challenges the common thinking that participating in a trial is beneficial—even in the placebo group—for cancer patients.
Next, Lukas Vogelsang, a postdoctoral fellow in the department of brain and cognitive sciences at the Massachusetts Institute of Technology, talks about research into color vision with “late-sighted” kids. Studying children who were born blind and then later gained vision gave researchers new insights into how vision develops in babies and may even help train computers to see better.
Last up on the show is the first in our series of books podcasts on a future to look forward to. Books host Angela Saini talks with author Claire Horn, a researcher based at Dalhousie University’s Health Justice Institute. They discuss the implications of growing babies from fertilized egg to newborn infant—completely outside the body—and Horn’s book Eve: The Disobedient Future of Birth.

Ritual murders in the neolithic, why 2023 was so hot, and virus and bacteria battle in the gut
18 april 2024 · 38 min
A different source of global warming, signs of a continentwide tradition of human sacrifice, and a virus that attacks the cholera bacteria Lees meer
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.

When did rats come to the Americas, and was Lucy really our direct ancestor?
4 april 2024 · 31 min
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 Lees meer
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.
