Flowers peeking up through the soil are a welcome sight after a long cold winter—and are one of the first markers of spring. Biologist David George Haskell argues that flowers aren’t just beautiful: They’re also critical to most ecosystems and the diversity of life as we know it. Flowering plants also make up a large part of human diets (rice, maize, and wheat are all flowers). And homing in on orchids, Haskell says, can help us understand the complex relationship between flowers and pollinators.
Guest:
Dr. David George Haskell is a biologist and author of: “How Flowers Made Our World: The Story of Nature’s Revolutionaries”

Folge vom 23.03.2026Apple: trying to think different for 50 yearsThe Apple Computer Company was founded on April 1, 1976, and in the 50 years since, the company has evolved from a handful of Silicon Valley misfits to a global technology and media powerhouse. Tech journalist David Pogue talks with Ira Flatow about the backstory of the company, and the leadership of the mercurial Steve Jobs. He offers a peek into some lesser known chapters of the company’s history, like the ill-fated Apple Paladin, a prototype Apple-produced fax machine. Pogue chronicles the company’s history in his latest book, “Apple: The First 50 Years.” Guest: David Pogue is a tech journalist, CBS Sunday Morning correspondent, and author of the book “Apple: The First 50 Years.” Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Folge vom 19.03.2026Building a digital ant gallery, from the ground upA 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.
