Big Picture Science for April. 25, 2022 - In Living Color

Big Picture Science - In Living Color

(REPEAT) The world is a colorful place, and human eyes have evolved to take it in – from vermillion red to bright tangerine to cobalt blue. But when we do, are you and I seeing the same thing?

Find out why color perception is a trick of the brain, and why you and I may not see the same shade of green. Or blue. Or red. Also, platypuses and the growing club of fluorescent mammals, and the first new blue pigment in more than two centuries.

Guests:

• Paula Anich – Associate Professor of Natural Resources, Northland College
• Michaela Carlson – Assistant Professor of Chemistry, Northland College
• Rob DeSalle – Curator at the American Museum of Natural History, and co-author of “A Natural History of Color: the Science Behind What We See and How We See It”
• Mas Subramanian – Professor of Materials Science at Oregon State University

Big Picture Science for April. 11, 2022 - Finding Endurance

Big Picture Science - Finding Endurance

In 1915, Endurance, the ship that took Ernest Shackleton to the Antarctic, was slowly crushed and sank. Shackleton, and the 28 men he brought with him, were camped on the ice near the ship, and watched helplessly as their transport went to a watery grave, two miles down.

But a recent expedition has found the Endurance, taking the world back to the last hurrah of the heroic age of polar expedition. How was it found, and what will be done with it?

Also, while feats of exploration inspire TV shows and magazine articles, do they have other functions in society? Is modern exploration more than just a nice thing to do?

We go to the bottom of the world on “Finding Endurance.”

Guests:

• Michael Smith – Author and journalist. His book: “Shackleton: By Endurance We Conquer”
• Christian Katlein – Sea ice physicist
• Tim Jarvis – Adventurer and environmental scientist

Big Picture Science for April. 4, 2022 - Go With the Flow

Big Picture Science - Go With the Flow

(REPEAT) Solid materials get all the production credit. Don’t get us wrong, we depend on their strength and firmness for bridges, bones, and bento boxes. But liquids do us a solid, too. Their free-flowing properties drive the Earth’s magnetic field, inspire a new generation of smart electronics, and make biology possible. But the weird thing is, they elude clear definition. Is tar a liquid or a solid? What about peanut butter?

In this episode: A romp through a cascade of liquids with a materials scientist who is both admiring and confounded by their properties; how Earth’s molten iron core is making the magnetic north pole high-tail it to Siberia; blood as your body’s information superhighway; and how a spittlebug can convert 200 times its body weight in urine into a cozy, bubble fortress.

Guests:

• Mark Miodownik – Professor of Materials and Society, University College, London, and author of “Liquid rules: The Delightful and Dangerous Substances that Flow Through Our Lives”
• Arnaud Chulliat – Geophysicist, University of Colorado and Institut de physique du globe du Paris
• Philip Matthews – Comparative physiologist at the University of British Columbia
• Rose George – Journalist and author of “Nine Pints: A Journey Through the Money, Medicine, and Mysteries of Blood”
