Anchoring radiocarbon dates to cosmic events, why hibernating bears don't get blood clots, and kicking off a book series on sex, gender, and science

First up this week, upping the precision of radiocarbon dating by linking cosmic rays to isotopes in wood. Producer Meagan Cantwell talks with Online News Editor Michael Price about how spikes in cosmic rays—called Miyake events—are helping archaeologists peg the age of wooden artifacts to a year rather than a decade or century.

Next on the show, we have a segment on why bears can safely sleep during hibernation without worrying about getting clots in their blood. Unlike bears, when people spend too much time immobilized, such as sitting for a long time on a flight, we risk getting deep vein thrombosis—or a blood clot. Johannes Müller-Reif of the Max Planck Institute of Biochemistry talks with host Sarah Crespi about what we can learn from bears about how and why our bodies decide to make these clots and what we can do to prevent them.

Stay tuned for an introduction to our new six-part series on books exploring science, sex, and gender. Guest host Angela Saini talks with scholar Anne Fausto-Sterling about the books in this year's lineup and how they were selected.

Why some countries, such as China, vaccinate flocks against bird flu but others don’t, and male ants that are always chimeras

First up this week, highly pathogenic avian influenza is spreading to domestic flocks around the globe from migrating birds. Why don’t many countries vaccinate their bird herds when finding one case can mean massive culls? Staff News Writer Jon Cohen joins host Sarah Crespi to discuss the push and pull of economics, politics, and science at play in vaccinating poultry against bird flu.

Next up, a crazy method of reproduction in the yellow crazy ants (Anoplolepis gracilipes). Hugo Darras, an assistant professor in the Institute of Organismic and Molecular Evolution at Johannes Gutenberg University, talks about how males of this species are always chimeras—which means their body is composed of two different cell lines, one from each parent.

On this week’s show: How people in the past thought about their own past, and a detailed look at how Braille is read

First up this week, what did people 1000 years ago think about 5000-year-old Stonehenge? Or about a disused Maya temple smack dab in the middle of the neighborhood? Contributing Correspondent Lizzie Wade joins host Sarah Crespi to discuss how Mesoamerican sites are revealing new ways that ruins were incorporated into past peoples’ lives.

Next up on this week’s show is a segment from the AAAS meeting on reading science and Braille. We hear from Robert Englebretson, an associate professor of linguistics at Rice University, about filling in a gap in reading science research when it comes to how Braille is read, written, and learned.

On this week’s show: Earth’s youngest impact craters could be vastly underestimated in size, and remaking a plant’s process for a creating a complex compound

First up this week, have we been measuring asteroid impact craters wrong? Staff Writer Paul Voosen talks with host Sarah Crespi about new approaches to measuring the diameter of impact craters. They discuss the new measurements which, if confirmed, might require us to rethink just how often Earth gets hit with large asteroids. Paul also shares more news from the recent Lunar and Planetary Science Conference in Texas.

Next up, pulling together all the enzymes used by a plant to make a vaccine adjuvant—a compound used to boost the efficacy of vaccines—in the lab. Anne Osbourn, a group leader and professor of biology at the John Innes Centre in Norwich, England, talks about why plants are so much better at making complex molecules, and an approach that allows scientists to copy their methods.
