RNA, the genetic messenger, makes sure the DNA recipe gives your cells exactly what they ordered. But sometimes that means inhibiting some other RNA that got the recipe wrong. This process is called RNA interference (RNAi), and it acts as a self-correcting system within the complicated genetic kitchen of your body. Alex Dainis explains the importance -- and exciting potential -- of RNAi.

Lesson by Alex Dainis, animation by Cinematic Sweden.

The Ancient Egyptian king Thutmose III described the chicken as a marvelous foreign bird that “gives birth daily.” Romans brought them on their military campaigns to foretell the success of future battles. Today, this bird occupies a much less honorable position – on dinner plates. Chris Kniesly explains the evolving role of chickens throughout history.

Lesson by Chris A. Kniesly, directed by Mark Phillips.

Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants. With this unprecedented level of control, he's managed to cure mice of analogs of PTSD and certain forms of blindness. On the horizon: neural prosthetics. Session host Juan Enriquez leads a brief post-talk Q&A.

From something as familiar as our bodies to things vast as the formation of galaxies, we can observe the process of self-assembly, or when unordered parts come together in an organized structure. Skylar Tibbits explains how we see self-assembly at work in biology and chemistry -- and even in our future technologies.

Uploaded 28-06-21

--

In 1943, Irena Sendler and Janina Grabowska froze when they heard Gestapo pounding on the front door. Knowing she was minutes from arrest, Irena tossed Janina her most dangerous possession: a glass jar containing the names of over 2,000 Jewish children she’d smuggled to safety from the Warsaw Ghetto. Who was this courageous woman? Iseult Gillespie details the life and legacy of Irena Sendler.

Lesson by Iseult Gillespie, directed by Chloé Gérard.

Space is where things happen. Time is when things happen. And sometimes, in order to really look at the universe, you need to take those two concepts and mash them together. In this first lesson of a three-part series on space-time, hilarious hosts Andrew Pontzen and Tom Whyntie go through the basics of space and time individually, and use a flip book to illustrate how we can begin to look at them together.

Lesson by Andrew Pontzen and Tom Whyntie, animation by Giant Animation Studios.

Two men, Estragon and Vladimir, meet by a tree at dusk to wait for someone named “Godot.” So begins a vexing cycle where the two debate when Godot will come, why they’re waiting and whether they’re even at the right tree. The play offers a simple but stirring question- what should the characters do? Iseult Gillespie shares everything you need to know to read the tragicomedy.

Since the 1950s, governments, companies, and researchers have been planting flags among the stars. But while it might seem like there’s plenty of room in space, some pieces of celestial real estate are more valuable than others. As far as human space exploration is concerned, Lagrange points may be the most important places in our solar system. So what exactly are they? Fabio Pacucci explains.

Explore the differences between farmed meat, plant-based meat, and lab-grown meat, and find out which is best for you and the planet.

--

In 2021, a survey of over 1,000 Americans found that nearly two-thirds had eaten plant-based meat alternatives in the past year. Many cited potential health and environmental benefits as their motivation. But are these alternative meats actually better for us and the planet? Carolyn Beans investigates the differences between farmed meat, plant-based meat, and lab-grown meat.

Ah, spring. As Demeter, Goddess of the Harvest, it’s your favorite season. Humans and animals look to you to balance the bounty of the natural world which, like any self-respecting Goddess, you do with a pair of magical dice.
