In the early days of the United States, cotton and tobacco crops on the east coast are remembered as big contributors to the ongoing slave trade. Meanwhile, the sugar cane plantations in Louisiana are often forgotten. Because of the back-breaking work of maintaining the sugar cane crops, white settlers started importing African slaves to do the work for them. It […]

Today I found out about Audie Murphy, the most decorated U.S. World War II veteran. Murphy was born on June 20, 1925 in Texas. His family was extremely poor, partially due to having twelve young mouths to feed. When his father abandoned the family when Audie was fifteen years old, he was forced to pick up some of the slack […]

“We shall look over the world, and survey the history of any other oppressed and enslaved people in vain, to find one which has made more progress within the same length as the colored people of the United States. These, and many other considerations which I might name, give brightness and fervor to my hopes that that better day for […]

In Dallas, Texas on November 22, 1963, the 35th President of the United States, John F. Kennedy, was assassinated. Despite two official investigations concluding that Lee Harvey Oswald shot and killed the President, doubts linger. This is due in no small part to the fact that neither Oswald, nor the official account, has ever been put on trial. Without the […]

Today I found out that Richard I, also known as Richard the Lionheart, spent most of his life in France and barely spoke English. Richard was born on Sept. 8, 1157 to Henry II and his formidable queen, Eleanor of Aquitaine in Oxford, England. He was the third son of the royal couple, and therefore not expected to inherit the […]

Today I found out that parrots name their chicks. Scientists have known for a while that, in addition to saying things like “Polly want a cracker” (see Bonus Facts below) to entertain humans, parrots appear to vocalize their own names. What was a mystery until a few years ago was if those names were innate, meaning the chicks teach other […]

Today I found out about Ranavalona I, the Mad Queen of Madagascar. Ranavalona I started out in life as a girl named Ramavo. Born in 1788 in Madagascar, she had humble origins as a commoner’s daughter. When her father learned of a plot to murder the future king, Andrianampoinimerina, he told his master and the plot was foiled. As thanks […]

Susan K. asks: Why do nuclear bombs make mushroom clouds? This phenomenon all comes down to a little something called the Rayleigh-Taylor instability, and by extension, convection. I’ll begin with the somewhat longer, but less geeky explanation before descending once again into extreme nerdery. It all starts with an explosion that creates a Pyrocumulus Cloud. This ball of burning hot […]

Today I found out about the fascinating tale of Belle Gunness, “The Lady Bluebeard,” who is thought to have murdered her husbands, her children, and a couple dozen more people during her lifetime. You probably remember Bluebeard, the title character in the French folk tale by Charles Perrault, which you might have stumbled across in a fairy tale book or […]

Myth: The Candirú fish can swim up your urine stream if you pee into the Amazon. If you’ve never heard of the Candirú, also known as the pencil fish, the toothpick fish, the vampire fish and the fish that SWIMS INTO YOUR PEE HOLE, Google any of those names above (yes, even that last one, but maybe not at work).

Among those who use recreational drugs, Bill Murray is something of an icon, having played several pot-smoking characters over the years, including the cannabis-loving sea captain Steve Zissou from The Life Aquatic with Steve Zissou, and noted drug user Hunter S. Thompson in Where the Buffalo Roam. So, was Bill Murray actually arrested for transporting Mary Jane, or was this story just […]

It is a sad truth that Native Americans suffer from alcoholism at rates far higher than those of other ethnic groups. While many causes likely contribute to this problem, some of those most commonly espoused, including lack of prior exposure to alcohol and genetic predisposition, are oft-repeated misconceptions. In fact, well before Europeans began to colonize the Americas, Native Americans […]

Immense, stretching up to nearly 70 feet long and weighing over 50 tons, the sperm whale is the seventh largest animal, and the largest with teeth, in the world. Prized for centuries because of its oil and the almost supernatural ambergris it creates, the sperm whale today remains vulnerable. And although we have hunted and studied this leviathan for well […]

Myth: Doctors are bound by the Hippocratic Oath. A binding agreement, as much a social contract as Social Security or Medicare, the traditional Hippocratic Oath holds those who swear to it to a strict code of professional and personal conduct. Contrary to popular belief, though, most doctors never take this oath, and, actually, most of us are probably glad they […]

Absent from the visible spectrum and neither a wave nor a particle, the color pink is, for many, a scientific enigma: how can a shade that doesn’t even appear in the rainbow exist? The answer lies in color theory. The Primary Colors: RGB Unlike art production (see below), when it comes to eyesight (and video production), the primary colors are […]

Luke asks: Why when I squint does it help me see things clearer? Squinting causes two reactions that help you visualize the world around you in better detail. First, it changes the shape of our eye, allowing light to be focused better. Secondly, it decreases the amount of light that is allowed to enter the eye. Light coming from a […]
