On this week’s show: Environmental concerns over Indonesia building a new capital on Borneo, and keeping an eye on pollution as it comes out of the tailpipe First up this week, Contributing Correspondent Dennis Normile talks with host Sarah Crespi about Indonesia’s plans for an ultragreen new capital city on the island of Borneo. Despite intentions to limit the environmental impact of the new urban center, many are concerned about unplanned growth surrounding the city which could threaten rare plants and animals.   Also this week, John Zhou, professor of environmental engineering at the University of Technology Sydney talks with Sarah about his Science Advances paper on reducing pollution from cars and trucks by live monitoring vehicle emissions using remote sensors.

On this week’s show: A pill derived from human feces treats recurrent gut infections, and how a squirrel’s microbiome supplies nitrogen during hibernation First up this week, Staff Writer Kelly Servick joins host Sarah Crespi to discuss putting the bacterial benefits of human feces in a pill. The hope is to avoid using fecal transplants to treat recurrent gut infections caused by the bacterium Clostridium difficile. Also this week, Hannah Carey, a professor in the department of comparative biosciences within the school of veterinary medicine at the University of Wisconsin, Madison, talks with Sarah about how ground squirrels are helped by their gut microbes during hibernation.

On this week’s show: Ethical concerns rise with an increase in open brain research, and how sharing saliva can be a proxy for the closeness of a relationship Human brains are protected by our hard skulls, but these bony shields also keep researchers out. With brain surgeries and brain implants on the rise, scientists are getting more chances to explore living brains. Staff Writer Kelly Servick joins host Sarah Crespi to talk about the ethics of doing research on patients undergoing intense medical procedures, and the kinds of research being done. Also this week, Ashley Thomas, a postdoctoral researcher in the brain and cognitive science department at the Massachusetts Institute of Technology, talks about the meaning behind sharing saliva. Spend any time with a baby lately? Were you in awe—eager to cuddle, kiss, even change a diaper? Or were you slightly horrified by the drool and other fluids seeping out of this new human? Your feelings on the matter might depend on your closeness with the baby and—as Thomas and colleagues write this week in Science—the baby may notice which way you feel. According to their results, babies, like adults, seem to recognize sharing saliva—like sharing food and utensils or kissing—as a signal of close relationships.
