Top New Science Podcasts: Poker’s Life Lessons, Peer Reviews & Mars’ Greenness

Nature PodcastsOn this week’s podcast, life lessons from poker, keeping things civil during peer review, a sweaty synthetic skin that can exude useful compounds, and Mars’s green atmosphere.

In this episode:

00:44 Deciding to play poker

When writer Maria Konnikova wanted to better understand the human decision making process, she took a rather unusual step: becoming a professional poker player. We delve into her journey and find out how poker could help people make better decisions. Books and Arts: What the world needs now: lessons from a poker player

A sweaty synthetic skin that can exude useful compounds, and Mars’s green atmosphere. Research Highlight: An artificial skin oozes ‘sweat’ through tiny poresResearch Highlight: The red planet has a green glow

11:21 Developing dialogues

The peer-review process is an integral part of scientific discourse, however, sometimes interactions between authors and reviews can be less than civil. How do we tread the fine line between critique and rudeness? Editorial: Peer review should be an honest, but collegial, conversation

Top New Science Podcasts: Universities Post-Covid And Drones Fighting Mosquito-Borne Disease

science-magazine-podcastsSenior Correspondent Jeffrey Mervis joins host Sarah Crespi to talk about how universities are dealing with the financial crunch brought on by the coronavirus. Jeff discusses how big research universities are balancing their budgets as federal grants continue to flow, but endowments are down and so is the promise of state funding.

Mosquito-borne infections like Zika, dengue, malaria, and chikungunya cause millions of deaths each year. Nicole Culbert and colleges write this week in Science Robotics about a new way to deal with deadly mosquitoes—using drones. The drones are designed to drop hundreds of thousands of sterile male mosquitoes in areas with high risk of mosquito-borne illness. The idea is that sterile male mosquitoes will mate with females and the females then lay infertile eggs, which causes the population to decline. They found this drone-based approach is cheaper and more efficient than other methods of releasing sterile mosquitoes and does not have the problems associated with pesticide-based eradication efforts such as resistance and off-target effects.

Top New Science Podcasts: “Neutron Star Interior Composition Explorer”

Nature PodcastsAn instrument on the International Space Station is providing new insights into some of the Universe’s most baffling objects. Neutron stars have puzzled scientists for decades. It’s known that these ultra-dense objects are born from the remnants of supernovae, yet what’s under their surface, and what processes that go on within them, remain a mystery.

Now, an instrument called the Neutron Star Interior Composition Explorer is providing new information to help answer these questions, ushering in a new era of research into these strange stars.

New Science Podcasts: Coronavirus Contact Tracing Apps, Sea Otters

science-magazine-podcastsStaff Writer Kelly Servick joins host Sarah Crespi to talk about the ins and outs of coronavirus contact tracing apps—what they do, how they work, and how to calculate whether they are crushing the curve. 

Edward Gregr, a postdoctoral fellow at the Institute for Resources, Environment, and Sustainability at the University of British Columbia, Vancouver, talks with Sarah about the controversial reintroduction of sea otters to the Northern Pacific Ocean—their home for centuries, before the fur trade nearly wiped out the apex predator in the late 1800s. Gregr brings a unique cost-benefit perspective to his analysis, and finds many trade-offs with economic implications for fisheries For example, sea otters eat shellfish like urchins and crabs, depressing the shellfishing industry; but their diet encourages the growth of kelp forests, which in turn provide a habitat for economically important finfish, like salmon and rockfish.

Top New Science Podcasts: Quantum States In Space Lab, Barcode Bacteria

nature-podcastsThis week, the spaceborne lab that allows investigation of quantum states, and the debate surrounding how mountain height is maintained.

Top New Science Podcasts: Higher Covid-19 Severity In Men, Bacteria Tracking

science-magazine-podcastsFirst up this week, Staff Writer Meredith Wadman talks with host Sarah Crespi about how male sex hormones may play a role in higher levels of severe coronavirus infections in men. New support for this idea comes from a study showing high levels of male pattern baldness in hospitalized COVID-19 patients.

Next, Jason Qian, a Ph.D. student in the systems biology department at Harvard Medical School, joins Sarah to talk about an object-tracking system that uses bacterial spores engineered with unique DNA barcodes. The inactivated spores can be sprayed on anything from lettuce, to wood, to sand and later be scraped off and read out using a CRISPR-based detection system. Spraying these DNA-based identifiers on such things as vegetables could help trace foodborne illnesses back to their source. Read a related commentary piece.
