A little over 100 years ago, President Woodrow Wilson signed the National Park Service into law, ensuring that the country’s most remarkable natural landscapes would be preserved for future generations. Today, national parks are more popular than ever, with millions of visitors passing through the system’s 400-odd properties each year. But even if you’re working to check every national park off your bucket list, you may be unfamiliar with some of these facts. For instance, did you know that Dolly Parton is an official ambassador to Great Smoky Mountains National Park? Or that Yosemite campaigned to host the Winter Olympics in 1932?
That’s just some of the trivia John Green shares in this latest video from Mental Floss on YouTube. You can check out all 31 facts above, then subscribe to our channel if you're still hungry for more brain food.
Is your asthma acting up? Try eating only boiled carrots for a fortnight. Or smoke a cigarette. Have you got a toothache? Electrotherapy might help (and could also take care of that pesky impotence problem). When it comes to our understanding of medicine and illnesses, we’ve come a long way in the past few centuries. Still, it’s always fascinating to take a look back into the past and remember a time when cocaine was a common way to treat everything from hay fever to hemorrhoids.
In this week's all-new edition of The List Show, Mental Floss editor-in-chief Erin McCarthy is highlighting all sorts of bizarre, old-timey medical cures. You can watch the full episode below.

If you’re a sucker for itty, bitty, furry animals, then you’ll want to drop whatever it is you’re doing and check out this video of the Denver Zoo’s newest resident. Uploaded by The Denver Post, the video shows a week-old sloth clinging to its mother, and it’s almost too cute to handle.
The healthy baby, whose name and sex have not yet been determined, was born on April 11 to its proud sloth parents: 23-year-old Charlotte Greenie and 28-year-old Elliot. It also has an older sister, named Baby Ruth, who was born in January of last year. Dad and Baby Ruth are “temporarily off-exhibit” to give mom and her newborn baby the chance to rest and bond in their habitat—an indoor aviary that's part of the zoo's Bird World exhibit.
The baby belongs to one of six species of sloth called the Linne's two-toed sloth, which is native to the rainforests of South America and are not currently considered threatened. Unlike their distant relatives the three-toed sloths, two-toed sloths are mostly nocturnal creatures. They also tend to move faster than their three-clawed counterparts, although fast is putting it generously.
Like many things sloths do, the baby was slow to arrive. Zoo officials predicted that Charlotte would give birth as early as January, but the expected due date may have been a miscalculation.
“Sloth due dates are notoriously challenging to predict because sloths are primarily active at night and we rarely observe their breeding,” the zoo said in a statement. “Our animal care team closely monitored Charlotte for months to ensure that she and the baby were healthy and gaining the appropriate amount of weight.”
The baby is expected to cling to its mother for at least six months. Zoo officials say the best time to visit mom and baby is in the late afternoon, when Charlotte is more likely to be active.
