Both honeybees and humans originated in East Africa, and the connection between us has survived the ages. Some of your favorite delicacies -- coffee, chocolate, mangoes -- have the honeybee to thank for their hard work of pollination. Dino Martins encourages us to remember how much we owe to these magnificent insects.

Teenager Cam Perron loved baseball, so he began writing letters to the veteran players on his baseball cards. He only wanted autographs, but eventually acquired something even richer: the often unsung history of the Negro leagues. After hearing the stories, Cam took it upon himself to help former Negro leaguers get the recognition, reimbursement and reconnection to the game that they deserved.

Talk by Cam Perron.

Can electric cars reclaim their place on the road? Discover how developments in battery technology are making these cars more efficient and powerful.

Uploaded 26-10-21

--

By the end of the 19th century, nearly 40% of American cars were electric. But these vehicles had a few major problems — early car batteries were expensive and inefficient, and the vehicles were twice the price of a gas-powered car. And so for the next several decades, gas-powered cars dominated the market. Can electric cars reclaim their place on the road? Daniel Sperling and Gil Tal investigate.

Lesson by Daniel Sperling and Gil Tal, directed by Lobster Studio.

After Rome was destroyed, people were wary of attachment to physical beauty. As Christianity gained traction, Romans instead began to focus on the metaphysical beauty of virtue, and art began to follow suit. James Earle discusses how Medieval paintings of Madonna were affected by this shift.

Explore how a toxin-producing bacterium causes tetanus, and how to identify its common symptoms and best prevention practices.

--

In the 5th century, a ship master was suffering from a nasty infection that caused his jaws to press together, his teeth to lock up, and the muscles in his neck and spine to spasm. Today we know this account to be one the first recorded cases of tetanus. So, what causes this peculiar infection? Louise Thwaites explores how tetanus affects our bodies, and how we can prevent it.

Lesson by Louise Thwaites, directed by Andrew Foerster, Rewfoe.

Your antivirus squad is up against a code that’s hijacked your mainframe. What you’ve learned from other infected systems, right before they went dark, is that it likes to toy with antivirus agents in a very peculiar way— and you’re the agent that’s been selected to go up against the malware. Can you figure out which disk that runs your mainframe has been corrupted? James Tanton shows how.

You’ve spent months creating a basketball-playing robot, the Dunk-O-Matic, and you’re excited to demonstrate its capabilities. Until you read an advertisement: “See the Dunk-O-Matic face human players and automatically adjust its skill to create a fair game for every opponent!” That’s not what you were told to create. Can you recalibrate your robot to make it a fair match? Dan Katz shows how.

Lesson by Dan Katz, directed by Igor Ćorić, Artrake Studio.
