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.
On this week’s show, senior correspondent Jeffrey Mervis joins host Sarah Crespi to discuss a new National Institutes of Health (NIH) grant program that aims to encourage diversity at the level of university faculty with the long-range goal of increasing the diversity of NIH grant recipients.
Hear the latest from the world of science, brought to you by Nick Howe and Shamini Bundell. This week, uncovering the structure of materials with useful properties, and quantum entanglement over long distances.
Sarah also talks with Damien Finch, a Ph.D. candidate in the School of Earth Sciences at the University of Melbourne, about the Kimberly region of Australia and dating its ice age cave paintings using charcoal from nearby wasp nests.
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.
