In human courtship, a grimace is not generally something one wants to see from a potential love interest. Not so with animals. Cats, horses, llamas, and giraffes are just some of the animals that exhibit the flehmen response, a grimace-like curling of the upper lip and extension of the neck that facilitates the detection of scents—and pheromones—through the vomeronasal organ located in the roof of the mouth. Where does the name "flehmen" come from?
Back in the day
The shores of the Bosphorus Strait were once lined with fortifications built by Byzantine emperors and Ottoman sultans protecting Constantinople. Today, one of the world's longest suspension bridges spans the Bosphorus, linking European Turkey with Asian Turkey. The bridge was completed on October 30, 1973—one day after the Turkish republic's 50th anniversary. A second bridge was finished in 1988. Which American comedian led children across the first bridge during its opening ceremony?
Born on a day like today
A major shaper of 20th-century poetry, Pound was one of the most famous and controversial modern literary figures—praised as a subtle and complex poet, dismissed as a naive egotist and pedant, and condemned as a traitor and reactionary. He was a founder of the imagist poetry movement, an editor of several periodicals, and a mentor to many noted writers of his day. Arrested for treason in 1945, he was deemed insane and committed. What did he write during his 12 years in a US mental institution?
