City Views: Cartagena In Columbia, South America

Cartagena is a port city on Colombia’s Caribbean coast. By the sea is the walled Old Town, founded in the 16th century, with squares, cobblestone streets and colorful colonial buildings. With a tropical climate, the city is also a popular beach destination. Reachable by boat are Isla de Barú, with white-sand beaches and palm trees, and the Islas del Rosario, known for their coral reefs.

Science: Climate Change Hits Desert Soil, Mayan Calendars In Guatemala

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.

Science: Longer Lives And Slower Mutations, The Largest Galaxy Structure

For biologists, a long-standing question has been why some animals live longer than others. This week a team have attempted to answer this, by measuring the rates that different animal species accumulate mutations. They show that longer-lived animals acquire mutations at a slower rate, which helps to explain why cancer risk does not scale with lifespan.

10:43 The war in Ukraine’s effects on global energy

Many European countries are dependent on Russian fossil fuels for energy production. Following Russia’s unprovoked invasion of Ukraine, these countries are looking to wean themselves off these fuels, which could have short- and long-term impacts on emissions and food production.

19:58 A new measurement of a particle’s mass hints at new physics

Last week, a new estimate of the W boson’s mass caused much excitement among physicists. The result suggests that this particle is heavier than theory predicts, a finding that could be the first major breach in the standard model of particle physics. However, measuring W bosons is notoriously tricky, and further work will be needed to confirm the finding.
