    Historically, most cars have run on gasoline, but that doesn’t have to be the case in the future: other liquid fuels and electricity can also power cars. So what are the differences between these options? And which one’s best? Dig into which fuel— gasoline, electric, biofuels, or electrofuels— is both affordable for consumers and sustainable for the planet.

    --

    One summer evening in 335 BCE, Alexander the Great was resting by the Danube River when a band of strangers approached his camp. Alexander had never seen anything like these tall, fierce-looking warriors with huge golden neck rings and colorful cloaks. They were Keltoi or Celts— a collection of independent tribes spread across Europe. Philip Freeman details the rise and fall of the ancient Celts.

    Explore the viruses which can cause herpes, how the infection affects your body, and what makes it so hard to prevent and cure.

    --

    In the 1st century CE, Emperor Tiberius made an unprecedented decision: banning kissing at all public events. This move was aimed at thwarting a puzzling outbreak, which many historians believe was an epidemic of oral herpes. Today, more than half the population is infected with herpes simplex virus. So, what causes herpes? And how can we treat it? Christine Johnston examines this stealthy virus.

    Lesson by Christine Johnston, directed by Igor Ćorić, Artrake Studio.

    Humans, octopi and pine trees alike are all made up of cells, tiny but sophisticated systems that keep life going. Cells are almost like tiny factories run by robots, with the nucleus, DNA, proteins, lipids, and vitamins and minerals all playing critical roles. George Zaidan and Charles Morton lay out the blueprint of a cell and explain how biochemistry binds all life together.

    Our bodies are constantly producing, purging, and recycling secretions to fulfill all sorts of functions. Our reproductive organs are no exception. Vaginas are engaged in ongoing cycles of fluid discharge. But it can be hard to know what is "normal" when there’s a taboo in talking about it. So, what’s healthy discharge? And when is there cause for concern? Elizabeth Micks investigates.

    TED-Ed videos are used in a variety of different educational scenarios around the world. Due to limited moderation tools and resources, we have made this video discussable only on ed.ted.com.

    Lilian Chen grew up playing Super Smash Brothers Melee. But when her love of the game led her to compete in national tournaments, she noticed a big gender imbalance that brought with it a troubling social dynamic. In this TEDYouth talk, Lilian details her experiences with sexism in the Smash community and how she is now aiming to raise awareness for this topic in a way that doesn’t shame male gamers.

    Dig into the Bengali tale of a trio of siblings who attempt to scale the fearsome Magic Mountain to gain treasures for their home.

    --

    Inspired by a king’s visit, a trio of siblings began building a palace, traveling far and wide to collect rare jewels, seeds, and marble. A holy man stopped by and told them of a Magic Mountain, east of north and north of east, where they’d find their most meaningful treasures. But, he said, only a true hero could complete the journey. Malay Bera shares the Bengali tale of Kiranmala's quest.

    Lesson by Malay Bera, directed by Héloïse Dorsan-Rachet.

    Although this folktale exists in multiple oral variants across the Bengali-speaking world, this video is based on a variant akin to the better-known literary version, “Kironmala", from Thakurmar Jhuli (1907), an anthology of Bengali folktales collected by Dakshinaranjan Mitra Majumdar in the early 20th century.

    --

    Gráinne, princess of Tara and bride-to-be, was furious. She had thought she was betrothed to a young soldier, bold and brilliant enough to be her equal. Yet it soon became clear she was expected to marry Fionn, a warrior far past his prime. Not willing to suffer this insult, Gráinne decided that before the wedding she would exact her revenge. Iseult Gillespie shares the Irish myth of Fionn's fury.

    Investigate the science behind how doctors use radioactive drugs and PET scans to detect and diagnose diseases like Alzheimer’s and cancer.

    Uploaded 19-03-19

    --

    Is there a way to detect diseases like cancer and Alzheimer’s before they advance too far? Doctors are using injected radioactive drugs that circulate through the body and act as a beacon for PET scanners. These diagnostic tools can detect the spread of diseases before they can be spotted with other types of imaging. So how exactly does this work, and is it safe? Pedro Brugarolas investigates.

    In 1900, Greek divers stumbled upon a 2,000-year-old shipwreck whose contents would shake our understanding of the ancient world. Among the remains were fragments of mangled wood and corroded metal, which archaeologists soon realized were parts of the oldest geared device ever discovered — and humankind’s first computer. So, how did it work? Max G. Levy explains the Antikythera mechanism.

    Batteries are a triumph of science—they allow smartphones and other technologies to exist without anchoring us to an infernal tangle of power cables. Yet even the best batteries will diminish daily, slowly losing capacity until they finally die. Why does this happen, and how do our batteries even store so much charge in the first place? Adam Jacobson gives the basics on batteries.

    Puzzle through this classic ethical dilemma and decide: does your upbringing affect your moral responsibility for your actions?

    --

    Jo the First is a ruthless dictator who rules with an iron fist. To most onlookers, his rule appears cruel and unjust. But for his beloved son JoJo, this life is all he’s ever known and he grows up to inherit his father’s role and style of rule. Given JoJo’s unusual upbringing, does he bear full moral responsibility for his actions? Michael Vazquez and Sarah Stroud dig into this ethical dilemma.

    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.
