Breeding better bees, and training artificial intelligence on emotional imagery

Imagine having a rat clinging to your back, sucking out your fat stores. That’s similar to what infested bees endure when the Varroa destructor mite comes calling. Some bees fight back, wiggling, scratching, and biting until the mites depart for friendlier backs. Now, researchers, professional beekeepers, and hobbyists are working on ways to breed into bees these mite-defeating behaviors to rid them of these damaging pests. Host Sarah Crespi and Staff Writer Erik Stokstad discuss the tactics of, and the hurdles to, pesticide-free mite control. Also this week, Sarah talks to Philip Kragel of the Institute of Cognitive Science at the University of Colorado in Boulder about training an artificial intelligence on emotionally charged images. The ultimate aim of this research: to understand how the human visual system is involved in processing emotion. And in books, Kate Eichorn, author of The End of Forgetting: Growing Up with Social Media, joins books host Kiki Sanford to talk about how the monetization of digital information has led to the ease of social media sharing and posting for kids and adults.

Next-generation cellphone signals could interfere with weather forecasts, and monitoring smoke from wildfires to model nuclear winter

In recent months, telecommunications companies in the United States have purchased a new part of the spectrum for use in 5G cellphone networks. Weather forecasters are concerned that these powerful signals could swamp out weaker signals from water vapor—which are in a nearby band and important for weather prediction. Freelance science writer Gabriel Popkin joins host Sarah Crespi to talk about the possible impact of cellphone signals on weather forecasting and some suggested regulations. In other weather news this week, Sarah talks with Pengfei Yu, a professor at Jinan University in Guangzhou, China, about his group’s work using a huge smoke plume from the 2017 wildfires in western Canada as a model for smoke from nuclear bombs. They found the wildfire smoke lofted itself 23 kilometers into the stratosphere, spread across the Northern Hemisphere, and took 8 months to dissipate, which line up with models of nuclear winter and suggests these fires can help predict the results of a nuclear war.

A cryo–electron microscope accessible to the masses, and tracing the genetics of schizophrenia

Structural biologists rejoiced when cryo–electron microscopy, a technique to generate highly detailed models of biomolecules, emerged. But years after its release, researchers still face long queues to access these machines. Science’s European News Editor Eric Hand walks host Meagan Cantwell through the journey of a group of researchers to create a cheaper, more accessible alternative. Also this week, host Joel Goldberg speaks with psychiatrist and researcher Goodman Sibeko, who worked with the Xhosa people of South Africa to help illuminate genetic details of schizophrenia. Though scientists have examined this subject among Western populations, much less is known about the underlying genetics of people native to Africa.

Brickmaking bacteria and solar cells that turn ‘waste’ heat into electricity

On this week’s show, Staff Writer Robert F. Service talks with host Sarah Crespi about manipulating microbes to make them produce building materials like bricks—and walls that can take toxins out of the air. Sarah also talks with Paul Davids, principal member of the technical staff in applied photonics & microsystems at Sandia National Laboratories, about an innovation in converting waste heat to electricity that uses similar materials to solar cells but depends on quantum tunneling. And in a bonus segment, producer Meagan Cantwell talks with Online News Editor David Grimm on stage at the AAAS annual meeting in Seattle. They discuss how wildfires can harm your lungs, crime rates in so-called sanctuary states, and how factors such as your gender and country of origin influence how much trust you put in science.

Science’s leading role in the restoration of Notre Dame, and the surprising biology behind how our body develops its tough skin

On this week’s show, freelance writer Christa Lesté-Lasserre talks with host Sarah Crespi about the scientists working on the restoration of Notre Dame, from testing the changing weight of wet limestone, to how to remove lead contamination from four-story stained glass windows. As the emergency phase of work winds down, scientists are also starting to use the lull in tourist activity to investigate the mysteries of the cathedral’s construction. Also this week, Felipe Quiroz, an assistant professor in the biomedical engineering department at the Georgia Institute of Technology and Emory University, talks with Sarah about his paper on the cellular mechanism of liquid-liquid phase separation in the formation of the tough outer layer of the skin. Liquid-liquid phase separation is when two liquids “demix,” or separate, like oil and water. In cells, this process created membraneless organelles that are just now starting to be understood. In this work, Quiroz and colleagues create a sensor for phase separation in the cell that works in living tissue, and show how phase separation is tied to the formation of the outer layers of skin in mice.

In addition, Cohen gives a rundown of his latest feature, which highlights the relationship between diseases and changing seasons—and how this relationship relates to a potential coronavirus vaccine. Also this week, from a recording made at this year’s AAAS annual meeting in Seattle, host Meagan Cantwell speaks with Alexandra Maertens, director of the Green Toxicology initiative at Johns Hopkins University, Baltimore, about the importance of incorporating nonanimal testing methods to study the adverse effects of chemicals.
