Explore the essential role vultures play in cleaning our ecosystems and why their conservation is key to a healthy planet.

--

In the African grasslands, a gazelle suffering from tuberculosis takes its last breath. The animal’s corpse threatens to infect the water, but for the vulture, this isn’t a problem: it’s a feast. With a stomach of steel that can digest diseased meat and waste, vultures are essential to removing dangerous pathogens from ecosystems. Kenny Coogan explores the importance of the desert’s cleanup crew.

Lesson by Kenny Coogan, directed by Mali Mamut.

In a CSI age, we take forensic science for granted. New York did not have a medical examiner or forensic toxicologist until 1918, whose eventual arrival changed the landscape of crime investigation forever. At TEDYouth 2012, Deborah Blum prompts the audience to solve crimes with chemistry.

If you read "Bob, a DJ and a clown" on a guest list, are three people coming to the party, or only one? That depends on whether you're for or against the Oxford comma -- perhaps the most hotly contested punctuation mark of all time. When do we use one? Can it really be optional, or is there a universal rule? TED-Ed explores both sides of this comma conundrum.

Dig into what caused the Irish potato famine, and explore how the UK government’s response turned the crisis into a catastrophe.

--

For over 200 years, potatoes thrived in Ireland; roughly half the country’s residents lived almost entirely on potatoes. But when harvesting began in 1845, farmers found their potatoes blackened and shriveled. While this failed harvest created a crisis, the government’s response turned it into a national catastrophe. Stephanie Honchell Smith digs into Ireland's Great Famine.

Lesson by Stephanie Honchell Smith, directed by Denys Spolitak.

When are humans most happy? To gather data on this question, Matt Killingsworth built an app, Track Your Happiness, that let people report their feelings in real time. Among the surprising results: We're often happiest when we're lost in the moment. And the flip side: The more our mind wanders, the less happy we can be. (Filmed at TEDxCambridge.)

Explore the data analysis method known as p-hacking, where data is misrepresented as statistically significant.

Uploaded 05-08-21

--

In 2011, a group of researchers conducted a study designed to find an impossible result. Their study involved real people, truthfully reported data, and commonplace statistical analyses. So how did they do it? The answer lies in a statistical method scientists often use to try to figure out whether their results mean something, or if they’re random noise. James A. Smith explores p-hacking.

Lesson by James A. Smith, directed by Anton Bogaty.

When you think about Einstein and physics, E=mc^2 is probably the first thing that comes to mind. But one of his greatest contributions to the field actually came in the form of an odd philosophical footnote in a 1935 paper he co-wrote -- which ended up being wrong. Chad Orzel details Einstein's "EPR" paper and its insights on the strange phenomena of entangled states.
