| 0:44.2 | We love finding fun stories to tell you about, and we're so glad you joined us today. I'm Callie. |
| 0:49.0 | Today you'll learn about how earthquakes shake up quartz to make golden nuggets, the discovery of a new type of cell, |
| 0:55.9 | and an effort to redefine sustainability in our oceans. |
| 0:59.4 | Ooh, these will be interesting. |
| 1:01.0 | In honor of one of my favorite shows, Gold Rush, I want to talk about that soft metal |
| 1:05.4 | that has been the object of human's desires for millennium. |
| 1:08.5 | It's gold. |
| 1:09.6 | Prospecting for gold conjures up an image of a crusty old |
| 1:12.1 | timer sluicing water and sand through a pan in the middle of a riverbed. A few gold flakes at the bottom |
| 1:17.1 | of the pan go into the pile, and eventually our prospector has enough to melt down into a nice |
| 1:22.2 | chunk of gold to sell in town. But then there's the mother load, right? Sure. It's in just about every western movie, |
| 1:28.7 | isn't it? Like a pickaxe breaks away some rock, and there hidden for millions of years, |
| 1:33.0 | it's a shiny golden boulder for the taking. Instant generational wealth. Yeah, exactly. So our |
| 1:39.2 | crusty prospector notwithstanding, so much of the world's gold is bind from veins of quartz. And of particular |
| 1:45.7 | interest, that's where you find a lot of nuggets, not just flakes, but actual gold nuggets. But while |
| 1:51.1 | scientists have known where to find the gold in those quartz veins, they never really understood how it got there. |
| 1:57.3 | Okay. I mean, I love a good mystery. So the question is, what's the connection between quartz and gold nuggets? |
| 2:04.4 | So researchers think they've discovered what brings these two minerals together, and it has everything to do with earthquakes and electricity. |
