Researchers have been making animal embryos from two different species, so-called “chimeras,” for years, by introducing stem cells from one species into a very early embryo of another species. The ultimate goal is to coax the foreign cells into forming an organ for transplantation. But questions abound: Can evolutionarily distant animals, like pigs and humans, be mixed together to produce such organs? Or could species closely related to us, like chimps and macaques, stand in for tests with human cells? Staff Writer Kelly Servick joins host Sarah Crespi to discuss the research, the regulations, and the growing ethical debate. Also this week, Sarah talks with Yossi Yovel of the School of Zoology and the Sagol School of Neuroscience at Tel Aviv University in Israel about his work on sensory integration in bats. Writing in Science Advances, he and his colleagues show through several clever experiments when bats switch between echolocation and vision. Yossi and Sarah discuss how these trade-offs in bats can inform larger questions about our own perception. For our monthly books segment, Science books editor Valerie Thompson talks with Lucy Jones of the Seismological Laboratory at the California Institute of Technology in Pasadena about a song she created, based on 130 years of temperature data, for an instrument called the “viola de gamba.” Read more on the Books et al. blog.

Host Sarah Crespi talks with undergraduate student Micheal Munson from Baylor University in Waco, Texas, about a smartphone app that scans photos in the phone’s library for eye disease in kids.  And Sarah talks with Todd Roberts of the University of Texas Southwestern Medical Center in Dallas, Texas, about incepting memories into zebra finches to study how they learn their songs. Using a technique called optogenetics—in which specific neurons can be controlled by pulses of light—the researchers introduced false song memories by turning on neurons in different patterns, with longer or shorter note durations than typical zebra finch songs.

Earthworms are easy … to find. But despite their prevalence and importance to ecosystems around the world, there hasn’t been a comprehensive survey of earthworm diversity or population size. This week in Science, Helen Philips, a postdoctoral fellow at the German Centre for Integrative Biodiversity Research and the Institute of Biology at Leipzig University, and colleagues published the results of their worldwide earthworm study, composed of data sets from many worm researchers around the globe. Host Sarah Crespi gets the lowdown from Philips on earthworm myths, collaborating with worm researchers, and links between worm populations and climate. Read a related commentary here.  Sarah also talks with Ziad Obermeyer, a professor in the School of Public Health at the University of California, Berkeley, about dissecting out bias in an algorithm used by health care systems in the United States to recommend patients for additional health services. With unusual access to a proprietary algorithm, inputs, and outputs, Obermeyer and his colleagues found that the low amount of health care dollars spent on black patients in the past caused the algorithm to underestimate their risk for poor health in the future. Obermeyer and Sarah discuss how this happened and remedies that are already in progress.

After their life as research subjects, what happens to lab monkeys? Some are euthanized to complete the research, others switch to new research projects, and some retire from lab life. Should they retire in place—in the same lab under the care of the same custodians—or should they be sent to retirement home–like sanctuaries? Online News Editor David Grimm joins host Sarah Crespi to discuss recently penned legislation that pushes for monkey retirements and a new collaboration between universities and sanctuaries to create a retirement pipeline for these primates. Sarah also talks with Dante Lauretta, principal investigator for NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) and a professor at the University of Arizona in Tucson, about the latest news from the asteroid Bennu. Within 1 week of beginning its orbit of the asteroid, OSIRIS-REx was able to send back surprising images of the asteroid ejecting material. It’s extremely rocky surface also took researchers by surprise and forced a recalculation of the sample return portion of the craft’s mission. This week’s episode was edited by Podigy.

One of the objectives of a value-added tax system is to simplify the administration of taxes, and this is accomplished by taxing almost everything and everyone, but allowing input tax credits (ITCs) for those who are not considered to be the final consumer of supplies. While many accounting and finance professionals understand the basic rules for claiming ITCs for GST/HST paid on property and services acquired in relation to an organization’s commercial activities, few have the time to explore some of the more complex issues associated with ITCs.
