2021/12/02

There has been so much research during the pandemic—an avalanche of preprints, papers, and data—but how much of it is any good? Contributing Correspondent Cathleen O’Grady joins host Sarah Crespi to discuss the value of poorly designed research on COVID-19 and more generally. In September, the volcano Cumbre Vieja on Spain’s Canary Islands began to erupt. It is still happening. The last time it erupted was back in 1971, so we don’t know much about the features of the past eruption or the signs it

Have you noticed the trees around you lately—maybe they seem extra nutty? It turns out this is a “masting” year, when trees make more nuts, seeds, and pinecones than usual. Science Staff Writer Elizabeth Pennisi joins host Sarah Crespi to discuss the many mysteries of masting years. Next, Producer Meagan Cantwell talks with Jean-Laurent Casanova, a professor at Rockefeller University and an investigator at the Howard Hughes Medical Institute, about his review article on why some people are more

The James Webb Space Telescope was first conceived in the late 1980s. Now, more than 30 years later, it’s finally set to launch in December. After such a long a road, anticipation over what the telescope will contribute to astronomy is intense. Daniel Clery, a staff writer for Science, joins host Sarah Crespi to talk about what took so long and what we can expect after launch. You might have heard that Greenland sharks may live up to 400 years. But did you know that some Pacific rockfish can live

2021/11/04

Some 80 countries around the world add folic acid to their food supply to prevent birth defects that might happen because of a lack of the B vitamin—even among people too early in their pregnancies to know they are pregnant. This year, the United Kingdom decided to add the supplement to white flour. But it took almost 10 years of debate, and no countries in the European Union joined them in the change. Staff Writer Meredith Wadman joins host Sarah Crespi to discuss the ongoing folate debate. Last

Simple animals like jellyfish and hydra, even roundworms, sleep. Without brains. Why do they sleep? How can we tell a jellyfish is sleeping? Staff Writer Liz Pennisi joins host Sarah Crespi to talk about what can be learned about sleep from these simple sleepers. The feature is part of a special issue on sleep this week in Science. Next is a look at centuries of alien invasions—or rather, invasive insects moving from place to place as humans trade across continents. Sarah talks with Matthew

Soil science goes deep, and making moldable wood

Science Magazine Podcast ·

2021/10/20

There are massive telescopes that look far out into the cosmos, giant particle accelerators looking for ever tinier signals, gargantuan gravitational wave detectors that span kilometers of Earth—what about soil science? Where’s the big science project on deep soil? It’s coming soon. Staff Writer Erik Stokstad talks with host Sarah Crespi about plans for a new subsoil observatory to take us beyond topsoil. Wood is in some ways an ideal building material. You can grow it out of the ground. It’s not

2021/10/14

This week we are covering the Science special issue on mass incarceration. Can a dog find a body? Sometimes. Can a dog indicate a body was in a spot a few months ago, even though it’s not there now? There’s not much scientific evidence to back up such claims. But in the United States, people are being sent to prison based on this type of evidence. Host Sarah Crespi talks with Peter Andrey Smith, a reporter and researcher based in Maine, about the science—or lack thereof—behind dog-sniff

In 2019, a SpaceX rocket released 60 small satellites into low-Earth orbit—the first wave of more than 10,000 planned releases. At the same time, a new field of environmental debate was also launched—with satellite companies on one side, and astronomers, photographers, and stargazers on the other. Contributing Correspondent Joshua Sokol joins host Sarah Crespi to talk about the future of these space-based swarms. Over the course of the first 18 months of the coronavirus pandemic, different variants

Today, most newborns get some biochemical screens of their blood, but whole-genome sequencing is a much more comprehensive look at an infant—maybe too comprehensive? Staff Writer Jocelyn Kaiser joins host Sarah Crespi to discuss the ethical ins and outs of whole-genome screening for newborns, and the kinds of infrastructure needed to use these screens more widely. Sarah also talks with three contributors to a series of vignettes on the importance of active learning for students in science,
