Podcast: Quantum dots in consumer electronics and a faceoff with the quiz master

Sarah Crespi takes a pop quiz on literal life hacking, spotting poverty from outer space, and the size of the average American vocabulary with Catherine Matacic.   From the magazine You can already buy a quantum dot television, but it’s really just the beginning of the infiltration of quantum dots into our everyday lives. Cherie Kagan is here to talk about her in depth review of the technology published in this week’s issue.   [Image: Public domain; Music: Jeffrey Cook]

Podcast: Reading pain from the brains of infants, modeling digital faces, and wifi holograms

This week, we discuss the most accurate digital model of a human face to date, stray Wi-Fi signals that can be used to spy on a closed room, and artificial intelligence that can predict Supreme Court decisions with Online News Editor Catherine Matacic. Caroline Hartley joins Sarah Crespi to discuss a scan that can detect pain in babies—a useful tool when they can’t tell you whether something really hurts. Listen to previous podcasts.

Doubts about the drought that kicked off our latest geological age, and a faceoff between stink bugs with samurai wasps

We now live in the Meghalayan age—the last age of the Holocene epoch. Did you get the memo? A July decision by the International Commission on Stratigraphy, which is responsible for naming geological time periods, divided the Holocene into three ages: the Greenlandian, the Northgrippian, and the Meghalayan. The one we live in—the Meghalayan age (pronounced “megalion”)—is pegged to a global drought thought to have happened some 4200 years ago. But many critics question the timing of this latest age and the global expanse of the drought. Staff writer Paul Voosen talks with host Sarah Crespi about the evidence for and against the global drought—and what it means if it’s wrong. Sarah also talks to staff writer Kelly Servick about her feature story on what happens when biocontrol goes out of control. Here’s the setup: U.S. Department of Agriculture researchers wanted to know whether brown marmorated stink bugs that have invaded the United States could be controlled—aka killed—by importing their natural predators, samurai wasps, from Asia. But before they could find out, the wasps showed up anyway. Kelly discusses how using one species to combat another can go wrong—or right—and what happens when the situation outruns regulators.

Peering inside giant planets, and fighting Ebola in the face of fake news

It’s incredibly difficult to get an inkling of what is going on inside gas giants Saturn and Jupiter. But with data deliveries from the Cassini and Juno spacecraft, researchers are starting to learn more. Science Staff Writer Paul Voosen talks with host Sarah Crespi about new gravity measurements from Cassini’s last passes around Saturn. Using these data, researchers were able to compare wind patterns on Saturn and Jupiter and measure the mass and age of Saturn’s rings. It turns out the rings are young, relatively speaking—they may have formed as recently as 10 million years ago, after dinosaurs went extinct. Megan Cantwell then talks to science writer Laura Spinney about how researchers are fighting conspiracy theories and political manipulation in the Democratic Republic of the Congo during the country’s ongoing Ebola outbreak. In a first, the government, nongovernmental organizations, and scientists are working with community leaders to fight misinformation—and they might actually be winning.

Privacy concerns slow Facebook studies, and how human fertility depends on chromosome counts

On this week’s show, Senior News Correspondent Jeffrey Mervis talks with host Sarah Crespi about a stalled Facebook plan to release user data to social scientists who want to study the site’s role in elections. Sarah also talks with Jennifer Gruhn, a postdoctoral research fellow at the University of Copenhagen Center for Chromosome Stability, about counting chromosomes in human egg cells. It turns out that cell division errors that cause too many or too few chromosomes to remain in the egg may shape human fertility over our reproductive lives. Finally, in this month’s book segment, Kiki Sanford talks with Daniel Navon about his book Mobilizing Mutations: Human Genetics in the Age of Patient Advocacy.
