Big Picture Science for July 21, 2025: The Play’s the Thing









Big Picture Science: The Play’s the Thing

REPEAT
Has children’s play become too safe? Research suggests that efforts to prioritize safety harms children’s mental and physical development during play and contribute to anxiety. One solution: introduce risk into play. We visit an adventure playground where kids play unsupervised with anything from scraps of metal to hammers and nails. Plus, what are the evolutionary benefits of play? After all, we’re not the only species who like to roughhouse, sled, or chase balls. And, reclaiming play for those who have outgrown recess.

Big Picture Science for July 14, 2025: Nuts and Bolts









Big Picture Science: Nuts and Bolts

REPEAT
How frequently do you think about fasteners like screws and bolts? Probably not very often. But some of them a storied history, dating back to Egypt in the 3rd century BC. They aren’t just ancient history. They help hold up our bridges and homes today. Join us as we dissect a handful of engineering inventions that keep our world spinning and intact.

Big Picture Science for Jul7 07, 2025: Coffee of the Future









Big Picture Science: 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.

Big Picture Science for June 30, 2025: What Moves Us








 

Big Picture Science: 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.
