Explore how the technology of gene drives could lead to the eradication of mosquitoes and what that could mean for our ecosystems.

--

Mosquitoes are responsible for more human deaths every year than any other animal, but very few of the 3,500 mosquito species actually transmit deadly diseases to humans. Scientists have been conducting experiments using engineered technologies called gene drives that could theoretically get rid of the most lethal mosquitoes. So, should we eradicate these pesky insects? Talya Hackett investigates.

Biologist Caitlin O'Connell-Rodwell has come to one big conclusion from her last twenty years studying elephants -- they're just like us. In this TEDYouth Talk, O'Connell-Rodwell details her work observing these incredible, social animals, examining several individual (and very familiar) characters that play, bond and argue in tight-knit extended families eerily similar to our own.

Five great revolutions have shaped political culture over the past 50 years, says theorist Ivan Krastev. He shows how each step forward -- from the cultural revolution of the '60s to recent revelations in the field of neuroscience -- has also helped erode trust in the tools of democracy. As he says, "What went right is also what went wrong." Can democracy survive?

Shakespeare sometimes gets a bad rap in high schools for his complex plots and antiquated language. But a quick peek into the rhythm of his words reveals a poet deeply rooted in the way people spoke in his time — and still speak today. Why do Shakespeare’s words have such staying power? David T. Freeman and Gregory Taylor uncover the power of iambic pentameter.

Explore how scientists define adulthood, and find out if there’s a specific age at which we reach maturity.

--

Most countries recognize 18 as the start of adulthood by granting various freedoms and privileges. Yet there’s no exact age or moment in development that we can point to as having reached full maturity. If there’s no consensus on exactly when we reach maturity, when do we actually become adults? Shannon Odell shares how scientists define adulthood using stages of brain development.

Lesson by Shannon Odell, directed by Biljana Labović.
