Phil Plait was on a Hubble Space Telescope team of astronomers who thought they may have captured the first direct photo of an exoplanet ever taken. But did the evidence actually support that? Follow along as Plait shows how science progresses -- through a robust amount of making and correcting errors. "The price of doing science is admitting when you're wrong, but the payoff is the best there is: knowledge and understanding," he says.

A shooting star crashes onto Earth and a hideous blob emerges. It creeps and leaps, it glides and slides. It's also unstoppable: no matter what you throw at it, it just re-grows and continues its rampage. The only way to save the planet is to cut the entire blob into precise acute triangles while it sleeps, rendering it inert. Can you stop the blob from destroying the planet? Dan Finkel shows how.

Amanda Williams shares her lifelong fascination with the complexity of color: from her experiences with race and redlining to her discovery of color theory to her work as a visual artist. Journey with Williams to Chicago's South Side and explore "Color(ed) Theory," a two-year art project in which she painted soon-to-be-demolished houses bold, monochromatic colors infused with local meaning -- catalyzing conversations and making the hidden visible.

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.

Bees are dying off in record numbers, but ecologist Noah Wilson-Rich is interested in something else: Where are bees healthy and thriving? To find out, he recruited citizen scientists across the US to set up beehives in their backyards, gardens and rooftops. Learn how these little data factories are changing what we know about the habitats bees need to thrive -- and keep our future food systems stable.

To get young kids to thrive in school, we need to do more than teach them how to read and write -- we need to teach them how to manage their emotions, says educator Olympia Della Flora. In this practical talk, she shares creative tactics she used to help struggling, sometimes disruptive students -- things like stopping for brain breaks, singing songs and even doing yoga poses -- all with her existing budget and resources. "Small changes make huge differences, and it's possible to start right now ... You simply need smarter ways to think about using what you have, where you have it," she says.

Esha Alwani began writing songs when she was six years old, shortly after being diagnosed with Tourette syndrome. And she noticed something amazing: whenever she played music, her involuntary tics suddenly went away. Listen along as Alwani explores the power of music and delights the audience with an ethereal performance of her piano ballad "I'm Not Loving You (My Mask)."

The Sun delivers more energy to Earth in one hour than all of humanity uses in an entire year. How can we make this power more accessible to everyone, everywhere? Solar designer Marjan van Aubel shows how she's turning everyday objects like tabletops and stained glass windows into elegant solar cells -- and shares her vision to make every surface a power station.

Whether she's describing bickering families, quiet declarations of love, or juicy gossip, Jane Austen's writing often feels as though it was written just for you. Her dry wit and cheeky playfulness informs her heroines, whose conversational tone welcomes readers with a conspiratorial wink. Iseult Gillespie explores the sly societal satire and unique tongue-in-cheek humor of Jane Austen. [Directed by Compote Collective, narrated by Bethany Cutmore-Scott, music by BigBanda Soundscapers].

From Shakespeare's plays to modern TV dramas, the unscrupulous schemer for whom the ends always justify the means has become a familiar character type we love to hate. For centuries, we've had a single word to describe such characters: Machiavellian. But is it possible that we've been using that word wrong this whole time? Pazit Cahlon and Alex Gendler investigate the origins of the term.
