Concrete is the second most-used substance on Earth (behind water), and it's responsible for eight percent of the world's carbon footprint. Cement researcher Karen Scrivener shares the research behind a pioneering new kind of cement known as LC3, which could slash carbon emissions from this crucial building material by 40 percent, if adopted at scale.

Origami, which literally translates to "folding paper," is a Japanese practice dating back to at least the 17th century. In origami, a single, traditionally square sheet of paper can be transformed into almost any shape, purely by folding. The same simple concepts yield everything from a paper crane with about 20 steps, to a dragon with over 1,000 steps. Evan Zodl explores the ancient art form.

What if tiny microparticles could help us solve the world's biggest problems in a matter of minutes? That's the promise -- and magic -- of quantum computers, says Matt Langione. Speaking next to an actual IBM quantum computer, he explains how these machines solve complex challenges like developing vaccines and calculating financial risk in an entirely new way that's exponentially faster than the best supercomputers -- and shares why industries should prepare now for this new leap in computing.

Documentary photographer Olivia Arthur has been exploring a new frontier: the evolution of the blurring line between humanity and technology. In this meditative talk, she shows her work documenting the remarkable ways humans have merged with machines -- from bionics and motorized limbs to synthetic muscles and strikingly realistic robots -- and offers wisdom on the complexity, adaptability and resilience of the human body.

Aliens have invaded ancient history: they've cropped up in humanity's past through popular television and movies, displacing facts with absurd yet commonplace beliefs like "aliens built the pyramids." Archaeologist Sarah Kurnick illustrates why these misconceptions perpetuate racist and xenophobic notions of history and culture -- and demonstrates how you can help debunk these dangerous, outlandish myths.

Online retailers resort to all kinds of strategies to separate you from your hard-earned money. Behavioral scientist Wendy De La Rosa names three tactics to look out for -- and shares how you can keep yourself from falling for them.

When catastrophe strikes, art prevails -- and has done so for centuries. In this fascinating talk, writer and director Cara Greene Epstein places the closing of theaters during the coronavirus pandemic in a historical context, exploring how we can use this intermission to imagine a more just, representative and beautiful world, onstage and off.

For over 30 years, thousands of people were imprisoned, tortured, and murdered under Rafael Trujillo's dictatorship in the Dominican Republic. Three sisters would go on to lead an underground revolution. But while their courage inspired many, it threatened the man in power, and their lives would come to a tragic early end. Who were these brave women? Lisa Krause tells the story of Las Mariposas. [Directed by Tomás Pichardo-Espaillat, narrated by Safia Elhillo, music by Cem Misirlioglu and Sergio Sayeg].

The COVID-19 pandemic changed the way we work for good. Can it also change it for the better? Consultant Patty McCord reviews four key insights employers and employees alike gleaned from their shift to working from home -- and shares how companies can use what they learned in lockdown to creatively and innovatively rethink how we do business.

What if we could we use biology to restore our balance with nature without giving up modern creature comforts? Advocating for a new kind of environmentalism, scientist and entrepreneur Emily Leproust rethinks modern sustainability at the molecular level, using synthetic biology to create green alternatives. From lab-developed insulin and disease-resistant bananas to airplanes made of super-strong spider silk, she explains how reading and writing DNA can lead to groundbreaking innovations in health, food and materials.
