In 1846, a Japanese policeman drew a legendary mermaid with scales like a coat of mail and flowing hair that ran all the way down to three mer-fins. He’d come across the creature while investigating a report of a greenish glow in the water and had listened as the fish-person forecasted a good harvest and added, almost as an aside: “Should an epidemic come,” the beaked Amabie said, “draw me and show me to the people.” An early Japanese newspaper re-printed the drawing using wooden block ...read more
St. Patrick, patron saint of Ireland, is best known for bringing Christianity to the Emerald Isle, but his story is chock-full of other legends and miracles, too.

When we speak to each other, we force air through the small opening of our throat and shape it with our mouths. This makes the air molecules bunch together in specific patterns on their way out. Those air molecules then expand again, pushing against their neighbors, which makes them contract, and s ...read more

That’s disingenuous.” The Tokyo robot was one of many robots and other forms of artificial intelligence (A ...read more
On Aug. 3, 2019, only hours after a mass shooting in El Paso, Texas, which left 23 people dead, a familiar talking point reared its head: video games were to blame. The question of whether video games incite real-world violence among kids and teens has been sparking controversy — and headlines — for decades. But despite more than 20 years of investigation, researchers have failed to prove a causal link between playing violent video games and committing acts of violence. What's more, a longit ...read more
