On this week’s show: Saving birds from city lights, and helping astronauts inhabit robots First up, Science Contributing Correspondent Josh Sokol talks with host Sarah Crespi about the millions of migrating birds killed every year when they slam into buildings—attracted by brightly lit windows. New efforts are underway to predict bird migrations and dim lights along their path, using a bird-forecasting system called . Next, we hear from Aaron Pereira, a researcher at the German Aerospace Center (DLR) and a guest researcher at the human robot interaction lab at the European Space Agency. He chats with Sarah about his Science Robotics paper on controlling a robot on Earth from the International Space Station and the best way for an astronaut to “immerse” themselves in a rover or make themselves feel like it is an extension of their body.  In a sponsored segment from Science and the AAAS Custom Publishing Office, Sean Sanders, director and senior editor for custom publishing, interviews Alberto Pugliese, professor of medicine, microbiology, and immunology at the University of Miami, about a program he leads to advance research into type 1 diabetes. This segment is sponsored by the Helmsley Charitable Trust and nPod (the Network for Pancreatic Organ Donors with Diabetes). This week’s episode was produced with help from Podigy. [Image: M.

On this week’s show: Climate change is killing critical soil organisms in arid regions, and early evidence for the Maya calendar from a site in Guatemala Staff Writer Elizabeth Pennisi joins host Sarah Crespi to discuss how climate change is affecting “biocrust,” a thin layer of fungi, lichens, and other microbes that sits on top of desert soil, helping retain water and create nutrients for rest of the ecosystem. Recent measurements in Utah suggest the warming climate is causing a decline in the lichen component of biocrust, which is important for adding nitrogen into soils. Next, Sarah talks with Skidmore College anthropologist Heather Hurst, who directs Guatemala’s San Bartolo-Xultun Regional Archaeological Project, and David Stuart, a professor of art history and director of the Mesoamerica Center at the University of Texas, Austin, about their new Science Advances paper. The study used radiocarbon dating to pin down the age of one of the earliest pieces of the Maya calendar. Found in an archaeological dig in San Bartolo, Guatemala, the character known as “seven deer” (which represents a day in the Maya calendar), was dated to 300 B.C.E. That early appearance challenges what researchers know about the age and origins of the Maya dating system. This week’s episode was produced with help from Podigy.

On this week’s show: A new measurement of the W boson could challenge physicists’ standard model, and an abundance of marine RNA viruses Staff Writer Adrian Cho joins host Sarah Crespi to discuss a new threat to the standard model of particle physics—a heavier than expected measurement of a fundamental particle called the W boson. They chat about how this measurement was taken, and what it means if it is right. Next, Sarah talks about the microscopic denizens of Earth’s oceans with Ahmed Zayed, a research scientist in the department of microbiology at Ohio State University, Columbus. They talk about findings from a global survey of marine RNA viruses. The results double the number of known RNA viruses, suggesting new classifications will be needed to categorize all this viral diversity. This week’s episode was produced with help from Podigy.
