For Alex Rosenthal (and many others), the answer is: absolutely nothing.

There’s a common idea that it takes 10,000 hours of practice to become great at something. From an early age, we are encouraged to choose our path, focus specifically, and start racking up those hours. But, what if these head starts aren’t helping us the way we think they do? What if there’s a better way to excel? David Epstein shares how a different approach could set us up for greater success. [...

In 1968, the American Heart Association made an announcement that would influence people’s diets for decades: they recommended that people avoid eating more than three eggs a week.

Hei Man Chan digs into this complex molecule. [...

When reading "Alice's Adventures in Wonderland," most readers visualize the queen’s croquet game play out in their heads. A few might see the scene in vivid detail.

Adam Zeman explores the science of aphantasia. [...

Burbery shares what geomythology has uncovered about dragons. [Dir...

Terry Kupers investigates. [Direct...

Dyslexia affects up to 1 in 5 people, but the experience of dyslexia isn't always the same.
