Happy lab animals may make better research subjects, and understanding the chemistry of the indoor environment
8 februari 2018 · 22 min
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. Lees meer
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
1 februari 2018 · 20 min
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. Lees meer
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.

The dangers of dismantling a geoengineered sun shield and the importance of genes we don’t inherit
25 januari 2018 · 24 min
Catherine Matacic—online news editor for Science—talks with Sarah Crespi about how geoengineering could reduce the harshest impacts of climate change, but make them even worse if it were ever turned off. Lees meer
Sarah also interviews Augustine Kong of the Big Data Institute at the University of Oxford in the United Kingdom about his Science paper on the role of noninherited “nurturing genes.” For example, educational attainment has a genetic component that may or may not be inherited. But having a parent with a predisposition for attainment still influences the child—even if those genes aren’t passed down. This shift to thinking about other people (and their genes) as the environment we live in complicates the age-old debate on nature versus nurture.

Debunking yeti DNA, and the incredibly strong arms of prehistoric female farmers
30 november 2017 · 22 min
The abominable snowman, the yeti, bigfoot, and sasquatch—these long-lived myths of giant, hairy hominids depend on dropping elusive clues to stay in the popular imagination—a blurry photo here, a big footprint there—but what happens when scientists try to pin that evidence down? Online News Editor David Grimm talks with Sarah Crespi about the latest attempts to verify the yeti’s existence using DNA analysis of bones and hair and how this research has led to more than the debunking of a mythic creature. Lees meer
Sarah also interviews Alison Macintosh of the University of Cambridge in the United Kingdom about her investigation of bone, muscle, and behavior in prehistory female farmers—what can a new database of modern women’s bones—athletes and regular folks—tell us about the labor of women as humans took up farming?

The world’s first dog pictures, and looking at the planet from a quantum perspective
22 november 2017 · 29 min
About 8000 years ago, people were drawing dogs with leashes, according to a series of newly described stone carvings from Saudi Arabia. Online News Editor David Grimm talks with Sarah Crespi about reporting on this story and what it says about the history of dog domestication. Lees meer
Sarah also interviews physicist Brad Marston of Brown University on surprising findings that bring together planetary science and quantum physics. It turns out that Earth’s rotation and the presence of oceans and atmosphere on its surface mean it can be described as a “topological insulator”—a term usually reserved for quantum phenomena. Insights from the study of these effects at the quantum level may help us understand weather and currents at the planetary level—including insights into climate change and exoplanets.
