0:00.0	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.
0:09.0	Time flies when you're learning super cool stuff. I'm Nate.
0:12.0	And I'm Kali. If you're dropping in for the
0:13.8	first time welcome to curiosity where we aim to blow your mind by helping you to grow your
0:17.5	mind. If you're a loyal listener, welcome back. Today you'll learn about a new
0:21.5	environmentally friendly way to make TV screens, what future space warfare might look like, and how we have finally completely unraveled the human genome.
0:31.0	Without further ado, let's satisfy some curiosity.
0:34.0	Okay, I've got an awesome story today about using something that is often thrown away
0:38.3	to make more environmentally friendly screens and monitors.
0:42.1	Now we're getting environmental improvements from the trash heap?
0:45.0	More like the compost heap.
0:48.0	A team of researchers recently created a system of silicon-based quantum dots that can be used to light LED screens from
0:54.6	synthesizing otherwise discarded rice husks. Screens from rice. That's
0:59.8	incredible but how does this all work and what is a quantum dot?
1:05.0	So quantum dots are human-made nanoparticles that emit color when hit with light.
1:09.6	The color of the light they emit depends on the size of the particle.
1:13.0	Larger quantum dots emit red light, while smaller ones emit green and blue.
1:17.0	The tiny particles are actually crystal semiconductors
1:20.0	and are often put in screens as a layer to enhance and widen the range of colors and
1:23.6	LCD screen can create. It helps make super high definition displays.
1:28.0	That's pretty fascinating technology. It's like when atoms emit light
1:31.6	when excited electrons return to lower energy levels,
	...
