Which is better: Soap or hand sanitizer? - Alex Rosenthal and Pall Thordarson

Dig into the science of how soap breaks down a coronavirus, and the effectiveness of hand sanitizer against a viral outbreak. -- Your hands, up close, are anything but smooth. With peaks and valleys, folds and rifts, there are plenty of hiding places for a virus to stick. If you then touch your face, the virus can infect you. But there are two extraordinarily simple ways you can keep that from happening: soap and water, and hand sanitizer. So which is better? Alex Rosenthal and Pall Thordarson investigate.

What really happened during the Salem Witch Trials - Brian A. Pavlac

Dig into how the infamous Salem Witch Trials began and why they remain a cautionary tale of the dangers of groupthink and scapegoating. -- You’ve been accused of a crime you did not commit. It’s impossible to prove your innocence. If you insist that you’re innocent anyway, you’ll likely be found guilty and executed. But if you confess, apologize, and implicate others, you’ll go free. This was the choice facing those accused of witchcraft in Salem, Massachusetts in the 17th century. How did this happen? Brian A. Pavlac investigates. Lesson by Brian A.

The most important anus in the ocean - Cella Wright

Explore the wonderfully bizarre life of the sea cucumber, and discover the essential role they play in keeping ocean ecosystems healthy. -- Is it a fuzzy sock? An overripe banana? A moldy tube of toothpaste? No! In fact, it’s a humble sea cucumber: a brainless, fleshy form surrounding a digestive tract, and bookended by a mouth and an anus. And while it might look odd, its daily toil paves the way for entire ecosystems to thrive. Cella Wright journeys to the bottom of the ocean to explore the lives of these sausage-shaped wonders.

The dark history of IQ tests - Stefan C. Dombrowski

Explore the history of IQ tests; how they measure a person’s intelligence and the ways they have been used to justify scientifically baseless ideologies. -- In 1905, psychologists Alfred Binet and Théodore Simon designed a test for children who were struggling in school in France.

Explore what makes trees a vital part of cities, and how urban spaces throughout history have embraced the importance of trees. -- By 2050, it’s estimated that over 65% of the world will be living in cities.
