On May 1, 1893, Chicago was abuzz. Two hundred thousand people jostled for a glimpse of the brand new city within the city, the so-called “White City.” Dignitaries, civic leaders, and politicians had all traveled far and wide to attend the day’s spectacle. Even President Grover Cleveland joined the festivities. After President Cleveland gave a triumphant speech about American progress, he pressed

In a move that will certainly tug on the heartstrings of anyone that grew up in the 90s, Representative Sam Liccardo (D-Ca.)and other co-sponsors have introduced the Save Willy Act, aiming to protect the whales that enter the San Francisco Bay. The bill’s appropriate name is inspired by the 1993 drama Free Willy, in which an orphan boy befriends and ultimately saves a captive orca . “With at leas

“Sugar rots your teeth!” You’ve likely heard those words, in some shape or form, coming from a parent, grandparent, teacher, or TV show. In school, you might have even conducted a classic experiment: putting an egg into a cup of soda to see how the shell softens and becomes flabby after a few days. That, the lesson implies, is what sugary soda does to your teeth. However, sugar is not the direct

At a wildlife park in Germany, a young ring-tailed lemur did something bold: It launched itself at an adult ruffed lemur and started gently slapping and grabbing her. Rather than putting an end to these antics, the bigger, stronger ruffed lemur just rolled onto her back, flashed a relaxed open-mouth expression, and let the little one tackle her. The playful wrestling match that ensued between the

I slide behind the wheel of an all-electric Cadillac Lyriq and fasten my seat belt. Blue skies and fluffy clouds surround me.

From the start, cars were built wrong. At least, that’s what Chrysler’s head of automotive research, Carl Breer, thought in 1930. Automobiles had never been built to be aerodynamic, he posited, and he was right. A few years earlier, he’d consulted aviation pioneer Orville Wright (the younger Wright brother) , who suggested he build a wind tunnel. The results were damning: Every car Breer tested w

Sperm whales ( Physeter macrocephalus ) go deep. They can dive 1,300 to 4,000 feet-deep and also travel as much as 15,000 miles per year.
