    Great news! We've been nominated for a Webby Award! Our three-part Katrina series is a finalist for Best News & Politics limited series podcast. Now, we need your help. Voting ends Thursday, April 16! Cast your vote at bit.ly/webbybipisci Antarctic scientists have long known the region’s ice sheet holds clues to the planet’s ancient past. Yet even the field’s foremost experts were shocked when they extracted a six-million-year-old ice core — twice as old as expected and the oldest recorded so far. Researchers say it will provide one of our best looks ever into Earth's climatological record. In a relatively more recent past, the discovery of 40,000-year-old notches and lines carved into artifacts and cave walls in Germany, examples of protowriting, suggest humans began documenting ideas thousands of years earlier than thought. Those timescales pale however, when compared to the age of the Earth’s most ancient rocks, which have a story to tell too. Find out how the planet’s most venerable rocks, formed billions of years ago, reveal the geological conditions that allowed life to get a foothold. Guests: Huw Groucutt – Archeologist, Department of Classics and Archeology, University of Malta Ed Brook – Paleoclimatologist and professor of Earth, Ocean and Atmospheric Sciences at Oregon State University Simon Lamb – Earth scientist and professor of geography in the School of Geography, Environment and Earth Sciences at Victoria University at Wellington, New Zealand.

    Amazing Arctic
    Apr 6 2026
    What’s it like to live on a block of ice, especially when it thaws? An environment writer shares his forty-year experience in the Arctic, including the time a paddling polar bear tracked him on a river. He describes the stunning beauty of America’s last truly wild place and the dramatic changes to the landscape he recently witnessed. Recent research has backed up his eyewitness accounts, as an arctic scientist presents the latest data collected from a part of world warming four times faster than the rest of the planet. Guests: Jon Waterman – Author of Into the Thaw: Witnessing Wonder Amid the Arctic Climate Crisis Twila Moon – Deputy Lead Scientist and Science Communication Liaison at the National Snow and Ice Data Center Descripción en español Featuring music by Dewey Dellay and Jun Miyake Originally aired March 17, 2025 Big Picture Science is part of the Airwave Media podcast network.

    Flower Power
    Mar 30 2026
    Before everything could come up roses, there had to be a primordial flower – the mother, and father, of all flowers. Now scientists are on the hunt for it. The eFlower project aims to explain the sudden appearance of flowering plants in the fossil record, what Darwin called an “abominable mystery.” Meanwhile, ancient flowers encased in amber or preserved in tar are providing clues about how ecosystems might respond to changing climates. And, although it was honed by evolution for billions of years, can we make photosynthesis more efficient and help forestall a global food crisis? Guests: Eva-Maria Sadowski - Post doctoral paleobotanist at the Museum für Naturkunde, Berlin Regan Dunn - Paleobotanist and assistant Curator at the La Brea Tar Pits and Museum Royal Krieger - Rosarian and volunteer at the Morcom Rose Garden, Oakland, California Ruby Stephens - Plant ecology PhD candidate at Macquarie University in Australia, and member of the eFlower Project Stephen Long - Professor of Plant Science, University of Illinois Descripción en español Originally aired March 13, 2023 Featuring music by Dewey Dellay and Jun Miyake You can get early access to ad-free versions of every episode by joining us on Patreon.
