Science Friday

A project called Antscan has generated high resolution images of thousands of ants, representing over 700 species. To make it happen, researchers brought preserved ants from collections around the world to a particle accelerator in Germany. There, a powerful synchrotron X-ray source combined with a vial-swapping robot allowed the researchers to build a collection of 3D ant images, inside and out. Each voxel (like a 3D pixel) has a resolution of 1.22 micrometers—enough to see the tiny hairs on ant bodies, and distinguish individual muscle fibers.

Antscan researcher Julian Katzke joins us to describe the background of the project, and how the images could be used for science and art.

Check out Antscan images at our website.

Guest:

Dr. Julian Katzke is a postdoc at the Smithsonian National Museum of Natural History.  He worked on the AntScan project while a PhD student at the Okinawa Institute of Science and Technology.

For decades, renowned environmental writer Elizabeth Kolbert has taken readers to remote corners of the planet to understand how all life is connected—and how our planet is changing. She’s covered everything from the collapse of insect populations to the success of one town’s effort to go carbon neutral. 

Host Flora Lichtman speaks with Kolbert about the undeniable heaviness of our current climate moment, how the splendor of the Great Barrier Reef “tilted” her worldview, and the messy business of trying to solve environmental problems. 

In March and April, the Science Friday Book Club is reading Kolbert’s latest book, “Life on a Little-Known Planet.” It’s a collection of essays she’s written over the years. Check out the Book Club to read along.

Guest:

Elizabeth Kolbert is a staff writer at The New Yorker and the author of several books, including “Life on a Little-Known Planet: Dispatches from a Changing World.”

There’s an idea bubbling up in medicine called the “digital twin.” The concept is to take personal health data like genetics, blood test results, tissue samples, MRI scans, and family history, and create a digital model of a patient that can be used to predict how a treatment might work for them. Think personalized medicine supercharged by AI. 

For example, cancer researchers are working on models that would create radiation and chemotherapy treatment plans based on the specifics of a patient’s tumor. But these models aren’t ready for the clinic yet, and with so much patient data involved, privacy concerns abound. 

Host Flora Lichtman talks with Caroline Chung, a radiation oncologist at the forefront of digital twin research.

Guest:

Dr. Caroline Chung is a radiation oncologist and the co-director of the Institute for Data Science Oncology at UT MD Anderson Cancer Center.

Farmers’ Almanacs have been around for hundreds of years, offering detailed advice about things like the best time to plant certain crops, and when to wean your calves. But do farmers actually use them? Host Flora Lichtman discusses their place in modern life with astronomer and Farmers’ Almanac contributor Dean Regas, and Missouri farmer Liz Graznak. 

Plus, zebra finches build their nests with a keen eye for color. But is their style easily swayed by feathered peer pressure? Zebra finch expert Lauren Guillette fills us in.

Guests:

Dean Regas is an astronomer and former Farmers’ Almanac contributor based in Cincinnati.

Liz Graznak is an organic farmer and owner of Happy Hollow Farm based in Columbia, Missouri. 

Lauren Guillette is an Associate Professor of Cognitive Ecology at the University of Alberta.

In February, conservationists released 158 young tortoises onto Floreana Island in the Galapagos. The Floreana tortoise subspecies had long been thought extinct, but the discovery of close relatives on another island made a captive breeding effort possible. 

SciFri turtle correspondent Charles Bergquist talks with conservationist Penny Becker about the science behind the reintroduction, and what it was like to return the species to an island that had not seen them since the 1850s. Plus, the latest on sea turtle nesting season, and an ancient sea turtle stampede.

Guest:

Dr. Penny Becker is CEO of the nonprofit Island Conservation.
