Top New Science Podcasts: Alien Life And Genotype-Tissue Expression (GTEx)

First up this week, Senior Correspondent Daniel Clery talks with host Sarah Crespi about how Breakthrough Listen—a privately funded initiative that aims to spend $100 million over 10 years to find extraterrestrial intelligent life—has changed the hunt for alien intelligence.

And as part of a special issue on the Genotype-Tissue Expression (GTEx) project, Brandon Pierce, a professor in the Departments of Public Health Sciences and Human Genetics at the University of Chicago, joins Sarah to discuss his group’s work on variation in the protective caps at the end of our chromosomes. The gradual shortening of these caps, also known as telomeres, has been associated with aging. Read more from the GTEx special issue.

Top New Science Podcasts: Arctic Sea Ice Under Seige, Climate Change Past Clues

Staff Writer Paul Voosen talks with host Sarah Crespi about how Arctic sea ice is under attack from above and below—not only from warming air, but also dangerous hot blobs of ocean water. 

 Next, Damien Fordham, a professor and global change ecologist at the University of Adelaide, talks about how new tools for digging into the past are helping catalog what happened to biodiversity and ecosystems during different climate change scenarios in the past. These findings can help predict the fate of modern ecosystems under today’s human-induced climate change. And in our books segment, Kiki Sanford talks with author Carl Bergstrom about his new book: Calling Bullshit: The Art of Skepticism in a Data-Driven World.

TOP NEW SCIENCE PODCASTS: NEW COVID-19 TESTING, HOW SPORTS BUILDS BONDS

Staff Writer Robert Service talks with host Sarah Crespi about a different approach to COVID-19 testing that might be useful in response to the high numbers of cases in the United States. To break chains of transmission and community spread, the new strategy would replace highly accurate but slow polymerase chain reaction (PCR) tests with cheaper, faster tests that are less accurate but can be administered frequently. 

Such tests cost between $1 and $3 compared with more than $100 for diagnostic PCR tests and give results in less than 30 minutes instead of days. Read all of our coronavirus coverage here. Also this week, Salma Mousa, a postdoctoral fellow at Stanford University, joins Sarah to talk about an experiment that added Muslim players to teams in a Christian soccer league in northern Iraq. The goal of the study was to see whether this type of social contact would change how the Christians—a threatened minority in the region—behaved toward Muslims, on and off the field. 

Top New Science Podcasts: Locust Swarm Triggers & Covid-19 Antibodies

Nature PodcastThis week’s Nature Podcast looks at: Triggering swarming behaviour in locusts, antibody therapies as a bridge to Covid-19 vaccine, and new insights into how humans synchronize.

In this episode:

01:56 Understanding swarming behaviour

Swarms of migratory locusts regularly devastate crops across the world, but why these swarms form has been a mystery. Now, a team of researchers have identified a compound that causes solitary locusts to come together in their billions – a finding that could have practical applications for preventing this behaviour. Research article: Guo et al.; News & Views: Catching plague locusts with their own scent

Top New Science Podcasts: Pluto’s Dark Side Yields Dwarf Planet’s Secrets

Nature PodcastsIn 2015, after a nine-and-a-half-year journey, NASA’s New Horizons spacecraft raced past Pluto, beaming images of the dwarf planet back to Earth.

Five years after the mission, researchers are poring over images of Pluto’s far-side, which was shrouded in shadow during New Horizon’s flypast. They hope that these images will help give a better understanding of how Pluto was born and even whether a hidden ocean resides beneath the world’s icy crust.

This is an audio version of our feature: Pluto’s dark side spills its secrets — including hints of a hidden ocean

Top New Science Podcasts: Pregnancy Risks Of Covid-19, Razor Blades & Hair

science-magazine-podcastsStaff Writer Meredith Wadman joins host Sarah Crespi to discuss the risk of the novel coronavirus infection to pregnant women. Early data suggest expectant women are more likely to get severe forms of the infection and require hospitalization. Meredith describes how the biology of pregnancy—such as changes to the maternal immune system and added stress on the heart and lungs—might explain the harsher effects of the virus.

Also this week, Sarah talks with Gianluca Roscioli about his experiments with commercial razor blades and real human hair. By using a scanning electron microscope, he was able to show how something relatively soft like hair is able to damage something 50 times harder like stainless steel.
