Engineering Plants That Fertilize Themselves to Save the World
Humans have relied on fertilizers to grow their plants for thousands of years. But the production of synthetic fertilizers also requires an immense amount of energy that comes primarily from fossil fuels and therefore contributes to...

Why Genetic Engineering Can’t Do Everything (Yet)
We've made some great strides in understanding the human genome, but before we can tackle genetic engineering, we have some "chicken and egg" problems to figure out. Hosted by: Hank Green

TED-Ed: 1816: The year with no summer | David Biello
In 1815, Mount Tambora erupted and its emissions spread across the globe, blotting out the sun for almost an entire year. This wreaked havoc on agriculture, leading to famines all across the Northern hemisphere. It was the year without...

TED: How to design a school for the future | Punya Mishra
In all the conversations about improving education for children, the voices of students, teachers and community members are often left out. Educational designer Punya Mishra offers a method to shift that paradigm, taking us through new...

TED-Ed: How do airplanes stay in the air? | Raymond Adkins
By 1917, Albert Einstein had explained the relationship between space and time. But, that year, he designed a flawed airplane wing. His attempt was based on an incomplete theory of how flight works. Indeed, insufficient and inaccurate...

TED: The future of machines that move like animals | Robert Katzschmann
Imagine a boat that propels by moving its "tail" from side to side, just like a fish. That's the kind of machine that TED Fellow Robert Katzschmann's lab builds: soft-bodied robots that imitate natural movements with artificial, silent...

TED-Ed: Why do beavers build dams? | Glynnis Hood
Nestled in the forests of Canada sits the world's longest beaver dam. This 850-meter-long structure is large enough to be seen in satellite imagery and has dramatically transformed the region, creating a pond containing 70 million liters...

The Unreasonable Efficiency of Black Holes
This video is about how efficient various reactions are at converting mass to energy (as we know from the Einstein mass-energy equivalence of E=mc^2). Antimatter is very efficient but it is not naturally-occurring. Chemical reactions...
