Coronavirus spreads financial turmoil to universities, and a drone that fights mosquito-borne illnesses

Senior 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. Read all our coronavirus coverage. 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.

The facts on COVID-19 contact tracing apps, and benefits of returning sea otters to the wild

Staff 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.   Read all our coronavirus coverage.   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.

Why men may have more severe COVID-19 symptoms, and using bacteria to track contaminated food

First 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.  Read all our coronavirus coverage. 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.  This week’s episode was produced with help from Podigy.

How scientists are thinking about reopening labs, and the global threat of arsenic in drinking water

Online news editor David Grimm talks with producer Joel Goldberg about the unique challenges of reopening labs amid the coronavirus pandemic. Though the chance to resume research may instill a sense of hope, new policies around physical distancing and access to facilities threaten to derail studies—and even careers. Despite all the uncertainty, the crisis could result in new approaches that ultimately benefit the scientific community, and the world.   Also this week, Joel Podgorski, a senior scientist in the Water Resources and Drinking Water Department at the Swiss Federal Institute of Aquatic Science and Technology, joins host Sarah Crespi to discuss the global threat of arsenic in drinking water. Arsenic is basically present in all rocks in minute amounts. Under the right conditions it can leach into groundwater and poison drinking water. Without a noticeable taste or smell, arsenic contamination can go undetected for years. The paper, published in Science, estimates that more than 100 million people are at risk of drinking  arsenic contaminated water and provides a guide for the most important places to test.   This week’s episode was produced with help from Podigy.   Listen to previous podcasts   About the Science Podcast   Download a transcript (PDF)  ++   [Image: Ian Aiden Relkoff/Wikipedia; Music: Jeffrey Cook]   Authors: Sarah Crespi; Joel Goldberg; David Grimm Learn more about your ad choices.

How past pandemics reinforced inequality, and millions of mysterious quakes beneath a volcano

Contributing Correspondent Lizzie Wade talks with host Sarah Crespi about the role of inequality in past pandemics. Evidence from medical records and cemeteries suggests diseases like the 1918 flu, smallpox, and even the Black Death weren’t indiscriminately killing people—instead these infections caused more deaths in those with less money or status. Also this week, Aaron Wech, a research geophysicist for the U.S. Geological Survey at the Alaska Volcano Observatory, joins Sarah to talk about recordings of more than 1 million earthquakes from deep under Hawaii’s Mauna Kea volcano, which hasn’t erupted in 4500 years. They discuss how these earthquakes, which have repeated every 7 to 12 minutes for at least 20 years, went undetected for so long. This week’s episode was produced with help from Podigy.

Making antibodies to treat coronavirus, and why planting trees won’t save the planet

Staff writer Jon Cohen joins host Sarah Crespi to talk about using monoclonal antibodies to treat or prevent infection by SARS-CoV-2. Many companies and researchers are rushing to design and test this type of treatment, which proved effective in combating Ebola last year. And Karen Holl, a professor of environmental studies at the University of California, Santa Cruz, joins Sarah to discuss the proper planning of tree planting campaigns. It turns out that just putting a tree in the ground is not enough to stop climate change and reforest the planet. This week’s episode was produced with help from Podigy.

Blood test for multiple cancers studied in 10,000 women, and is our Sun boring?

Staff Writer Jocelyn Kaiser joins Sarah to talk about a recent Science paper describing the results of a large study on a blood test for multiple types of cancer. The trial’s results suggest such a blood test combined with follow-up scans may help detect cancers early, but there is a danger of too many false positives. And postdoctoral researcher Timo Reinhold of the Max Planck Institute for Solar System Research joins Sarah to talk about his paper on how the Sun is a lot less variable in its magnetic activity compared with similar stars—what does it mean that our Sun is a little bit boring?   This week’s episode was produced with help from Podigy.
