| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Curiosity.com. |
| 0:06.0 | I'm Cody Goff. And I'm Ashley Hamer. |
| 0:08.0 | Today you'll learn how scientists just created the smallest flying human-made structure ever, |
| 0:13.7 | why you probably shouldn't swear by your Myers-Brigs results, |
| 0:17.1 | and the mysterious reason why the biggest nuts end up on top. |
| 0:21.1 | Let's satisfy some curiosity. |
| 0:24.4 | You might think the legroom on airplanes leaves a lot to be desired, but it's downright |
| 0:29.3 | roomy compared to the invention I'm going to tell you about. |
| 0:32.8 | Scientists have just made a data collecting micro flyer |
| 0:36.7 | that's 500 micrometers across, |
| 0:39.6 | or about the size of a grain of sand. |
| 0:43.0 | And it's the smallest flying structure ever made. |
| 0:47.0 | It doesn't fly on its own, though. |
| 0:49.0 | The Northwestern University researchers created tiny winged microchips inspired by the design of wind-dispersed seeds. |
| 0:56.7 | Like the seeds of maple trees, they spin like a helicopter as they fall. |
| 1:02.0 | That slows their descent, which gives them enough time. like a helicopter as they fall. |
| 1:02.8 | That slows their descent, which gives them enough time to collect data on the way down. |
| 1:07.5 | They're so light that wind can easily pick them up, and they can travel and collect data across great distances. |
| 1:14.0 | What kind of data, you might ask? |
| 1:16.0 | We're talking things like air pollution, atmospheric conditions, nuclear radiation, |
| 1:21.0 | and even disease outbreaks. |
| 1:23.4 | The team also touts the invention's ability to do population surveillance, which sounds scarier |
