Big Picture Science for Jul7 07, 2025: Coffee of the Future
REPEAT
Drinking a cup of coffee is how billions of people wake up every morning. But climate change is threatening this popular beverage. Over 60% of the world’s coffee species are at risk of extinction. Scientists are searching for solutions, including hunting for wild, forgotten coffee species that are more resilient to our shifting climate. Find out how the chemistry of coffee can help us brew coffee alternatives, and how coffee grounds can be part of building a sustainable future.
Guests:
* Christopher Hendon - Assistant Professor of Computational Materials Chemistry, University of Oregon
* Shannon Kilmartin-Lynch - Associate Professor of Civil Engineering, Monash University, Australia
* Aaron Davis - Senior Research Leader of Crops and Global Change, Royal Botanical Gardens, Kew

Big Picture Science for June 30, 2025: What Moves Us
What physical activity gives you joy? Whether it’s walking, running, dancing or swimming, your body evolved to do it. We are made for movement. But there’s a cost, as anyone with a sore neck or aching back knows. From the tiny muscles in our skin, which raise the hair on our arms, to the intricate mix of bone, blood vessels, and nerves in our neck, natural selection has struck a delicate and sometimes wacky balance between utility and form. In this episode, we explore how parts of the body - our muscles, neck and feet - came to be, and what forces prompted the evolution of efficient yet imperfect bodies.
Guests:
* Kent Dunlap - Professor of biology at Trinity College in Hartford, Connecticut and author of “The Neck: A Natural and Cultural History”
* Bonnie Tsui - Journalist and author of “On Muscle: The Stuff That Moves Us and Why It Matters”
* Jeremy DeSilva - Anthropologist at Dartmouth College and author of “First Steps, How Upright Walking Made Us Human”
