Neandertals that made art, live news from the AAAS Annual Meeting, and the emotional experience of being a scientist
We talk about the techniques of painting sleuths, how to combat alternative facts or “fake news,” and using audio signposts to keep birds from flying into buildings. For this segment, David Grimm—online news editor for Science—talks with host Sarah Crespi as part of a live podcast event from the AAAS Annual Meeting in Austin.
Sarah also interviews Science News Editor Tim Appenzeller about Neandertal art. The unexpected age of some European cave paintings is causing experts to rethink the mental capabilities of our extinct cousins.
For the monthly books segment, Jen Golbeck interviews with William Glassley about his book, A Wilder Time: Notes from a Geologist at the Edge of the Greenland Ice.

Some of our genes come alive after we die. David Grimm—online news editor for Science—talks with Sarah Crespi about which genes are active after death and what we can learn about time of death by looking at patterns of post-mortem gene expression.
Sarah also interviews David Merritt Johns of Columbia University about the so-called sugar conspiracy. Historical evidence suggests despite recent media reports, it is unlikely that “big sugar” influenced U.S. nutrition policy and led to the low-fat diet fad of the ’80s and ’90s.

Happy lab animals may make better research subjects, and understanding the chemistry of the indoor environment
Would happy lab animals—rats, mice, even zebrafish—make for better experiments? David Grimm—online news editor for Science—talks with Sarah Crespi about the potential of treating lab animals more like us and making them more useful for science at the same time.
Sarah also interviews Jon Abbatt of the University of Toronto in Canada about indoor chemistry. What is going on in the air inside buildings—how different is it from the outside? Researchers are bringing together the tools of outdoor chemistry and building sciences to understand what is happening in the air and on surfaces inside—where some of us spend 90% of our time.

Following 1000 people for decades to learn about the interplay of health, environment, and temperament, and investigating why naked mole rats don’t seem to age
David Grimm—online news editor for Science—talks with Sarah Crespi about the chance a naked mole rat could die at any one moment. Surprisingly, the probability a naked mole rat will die does not go up as it gets older. Researchers are looking at the biology of these fascinating animals for clues to their seeming lack of aging.
Sarah also interviews freelancer Douglas Starr about his feature story on the Dunedin Multidisciplinary Health and Development Study—a comprehensive study of the lives of all the babies born in 1 year in a New Zealand hospital. Starr talks about the many insights that have come out of this work—including new understandings of criminality, drug addiction, and mental illness—and the research to be done in the future as the 1000-person cohort begins to enter its fifth decade.
