The invention of the screw was over 2300 years ago. Yet this simple object remains the fastener in nearly every modern-day invention. This week we unwind the history and importance of ingenious and deceptively simple devices in: “Nuts and Bolts”. buff.ly/RtvkoQ9

What’s the big deal about tiny devices like springs and screws? This week, Roma Agrawal 🔩 shows us how the world as we know it couldn’t function without these simple, but ingenious, objects. This week, we bring you the “Nuts and Bolts:" bigpicturescience.org/episodes/nuts-…

Big Picture Science Roma Agrawal 🔩 Fun / interesting episode. Sent me on a deeper dive about hot riveting. Wild 😲 How have I just taken that for granted?!

This week, we're showing appreciation for the little things in life. Fasteners like rivets and screws may be simple inventions, but we rely on them to hold our world together. We're getting into the "Nuts and Bolts:" buff.ly/RtvkoQ9

From nuts and bolts, to rivets and screws, and even wheels and springs, our world is held together by a few seemingly simple inventions. But is our knowledge of how these mechanisms work disappearing? Find out more on this week's episode, "Nuts and Bolts" buff.ly/RtvkoQ9

Structural engineer Roma Agrawal 🔩 spends most of her time thinking about how to build big structures. But every large design challenge relies on a few small mechanisms in order to work. Learn more on this week's episode: buff.ly/RtvkoQ9

If your wristwatch is working properly, you probably aren't thinking much about the over 20 screws and springs that keep it ticking. Roma Agrawal 🔩 explores the small mechanisms that make everyday items possible on this week's episode: buff.ly/RtvkoQ9

If you were building a skyscraper, you'd probably want it to have a solid foundation. But flexibility is also important, explains Roma Agrawal 🔩. She explains how springs help protect buildings from natural disasters in this week's episode buff.ly/RtvkoQ9

Humans have used simple inventions like screws and bolts for centuries. In fact, the screws we use today aren't much different than the ones used by ancient Egyptians. We explore the seven small inventions that changed the world in "Nuts and Bolts" buff.ly/RtvkoQ9

The invention of the wheel and axle was certainly a turning point in human history. But do you know why the wheel was originally invented? Find out the surprising answer in this week's episode, "Nuts and Bolts" buff.ly/RtvkoQ9

We tend to throw out broken objects rather than repair them. And in some cases, they've been designed so we can't repair them at all, says Roma Agrawal 🔩. We're diving into the "Nuts and Bolts" buff.ly/RtvkoQ9

Why researchers are recommending that parents let kids play unsupervised in playgrounds that might resemble junkyards. Also, evolutionary benefits of play in other species from crows to wolves to bees. This week, “The Play’s the Thing” buff.ly/nljGcsm

Could play have evolutionary benefits? From sledding crows to roughhousing wolves to bees rolling balls, we examine how play shapes the animal kingdom. Plus, why children need risky play. It’s “The Play’s the Thing” this week: buff.ly/nljGcsm

PBS News is not going anywhere. We will continue our work without fear or favor, as we have for nearly five decades on the air. We are profoundly grateful to Viewers Like You for your loyalty and unwavering support.

If you've ever seen a video of a crow sledding down a roof or an octopus bouncing a ball, then you know humans aren't the only animals who love to play. But why did play evolve in the first place? This week, "The Play's the Thing:" buff.ly/nljGcsm

Play reinforces important neural networks, explains science writer David Toomey. Tune in to this week's episode to hear more about what tickling rats has taught us about the neurology of play and its link to social behavior: buff.ly/nljGcsm

When you picture an animal playing, what do you think of? A dog chasing a ball? A cat playing with string? Well, it's not just mammals that enjoy playtime. Find out the playful creature that surprised author David Toomey the most on this week's episode: buff.ly/nljGcsm

Play is important for a child's development. But has children's play become too safe? This week, we look at how risky play can be beneficial for both physical and mental health. buff.ly/nljGcsm

Researchers are recommending that parents allow their kids to engage in more "risky" play. One way to accomplish this is by playing at an adventure playground, like the one host Molly Bentley visited in New York City. Here, the kids make the rules. buff.ly/nljGcsm

Avoiding risk in play entirely means children miss out on a lot, explains psychologist Mariana Brussoni. From building self confidence to understanding their physical limits, taking risks during playtime is important. buff.ly/nljGcsm
