    Vultures: The acid-puking, plague-busting heroes of the ecosystem - Kenny Coogan

    Explore the essential role vultures play in cleaning our ecosystems and why their conservation is key to a healthy planet. Uploaded 24-02-20 -- 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.

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. Lesson by TED-Ed, animation by Zedem Media. Learn more about your ad choices.

    What actually triggered the Irish Potato Famine - Stephanie Honchell Smith

    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.

    The method that can "prove" almost anything - James A. Smith

    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.

    Ethical dilemma: What renders life worth living? - Douglas MacLean

    Puzzle through a classic ethical dilemma and decide: can human existence be meaningful without its creativity and culture? -- Life on your planet depends entirely on Nuronium for normal cognition. Unfortunately, its source has been compromised and you are now at risk of extinction. Scientists have found an alternate energy source, Polixate, but it can’t sustain cognition and would mean the loss of people's creativity. So, what shall it be: extinction or life without culture? Douglas MacLean explores this classic dilemma. Lesson by Douglas MacLean, directed by Asparuh Petrov, Compote Collective. This video was produced in collaboration with the Parr Center for Ethics, housed within the renowned Philosophy Department at the University of North Carolina at Chapel Hill. The Parr Center is committed to integrating abstract work in ethical theory with the informed discussion of practical ethical issues, and prides itself on the development of innovative and inclusive approaches to moral and civic education.
