B.Nice26 asks: Is there really such a thing as a truth serum? It sounds like something taken directly from the pages of Harry Potter—truth serum, or drugs that “make people tell the truth.” Somewhat recently a U.S. judge approved the use of truth serum on James Holmes, the accused Aurora, Colorado “Batman” shooter. So clearly the answer to your question […]

Myth: Frequently wearing a hat will cause permanent hair loss. I was once told by my mother that wearing a hat would cause me to go bald. I’m not sure if she actually knew what causes baldness or if she simply didn’t like my Seattle Seahawks hat (stupid Pittsburgh Steelers fans!). Either way, the idea that wearing a hat will […]

Today I found out about the history of the Rosetta Stone and how hieroglyphics were first translated. Hieroglyphics were elaborate, elegant symbols used prolifically in Ancient Egypt. The symbols decorated temples and tombs of pharaohs. However, being quite ornate, other scripts were usually used in day-to-day life, such as demotic, a precursor to Coptic, which was used in Egypt until […]

Today I found out dogs and cats are typically right pawed or left pawed. This is according to two studies, one done at the Ataturk University in Turkey (in 1991) and another at the University of Manchester in England (in 2006). According to the Ataturk University study, the majority of domestic cats are right pawed (50%), 10% of them are […]

If you’ve ever been to London, or even seen a picture of London, you’ve probably seen the giant clock tower at the corner of the Palace of Westminster. This tower is one of London’s major icons, ranking right up there with red double-decker buses, the London Eye, and Platform 9 ¾. Contrary to popular belief, the clock tower itself is […]

Today I found out men wore high heel shoes long before women. The first high heel wearers are believed to have been Persian horseback warriors sometime around the ninth century. The extended heel was reportedly developed specifically for riding, to keep the rider’s foot from slipping out of the stirrups. It also helped to hold the rider steady when standing […]

We are all familiar with the colloquialism “gaydar” which refers to a person’s intuitive, and often wildly inaccurate, ability to assess the sexual orientation of another person. In the 1960s, the Royal Canadian Mounted Police (RCMP) attempted to use a slightly more scientific, though equally flawed, approach- a machine to detect if a person was gay or not. This was […]

Today I found out the origin of the phrase “once in a blue moon” and what a blue moon actually is. “Once in a blue moon” today means “very rarely,” though it used to mean something that was absurd, right along the lines of “when pigs fly.” The first known recorded use of a form of the phrase is in […]

Tsutomu Yamaguchi died from stomach cancer. The cancer part perhaps isn’t surprising given that Yamaguchi is currently the only person officially recognized by the Japanese government as having lived through the atomic bombings of both Hiroshima and Nagasaki. (Note: There were actually well over a 100 or so others as well, perhaps as many as 165; they just have never […]

Dev asks: Why does XOXO mean hugs and kisses? You’ve seen XO as a sign-off representing love, affection, or friendship on letters, cards, emails, chat rooms and text messages. You may have even been torn on whether or not to include both the X and the O, considering one signifies hugs and the other means kisses. Use the incorrect symbol, […]

Today I found out that the makers of Barbie used to sell a doll whose breasts grew when her arm rotated. Yes, you read that correctly. It was 1975 and the doll was called “Growing Up Skipper”. When you rotated her arm, she grew an inch taller and her small breasts grew out of her plastic chest. She could return […]

They’re coming. If you live on the Eastern seaboard of North America, prepare this summer for a large-scale invasion of a species of cicada (“cicada” being the Latin for “tree cricket”) that hasn’t happened in 17 years. You will probably hear them before you see them, as a male swarm of these insects can produce noise at over 100 dB. The […]

Ben Franklin was a man of many and varied accomplishments- a Renaissance man in the grand tradition of Leonardo da Vinci. He was a writer, scientist, musician, inventor and innovator, despite only ever receiving 2 years of formal schooling. His ideas and principles helped shape his fledgling nation, and his diplomatic skills assured the newly born United States of America […]

Myth: The Great Chicago Fire was started by a cow. The Great Chicago Fire destroyed 3.3 square miles of Chicago, Illinois, burning for two days in 1871—between October 8th and October 10th. It killed hundreds of people, left more than 100,000 homeless (nearly one third of Chicago’s residents at the time), destroyed roughly 17,000 buildings, and caused a couple hundred […]

Corsets dominated the undergarments of wealthier women in the Western world for centuries, until WWI. So how did the war help popularize the bra? In a word, or two words in this case: metal shortage. The making of corsets required quite a bit of metal. Thus, in 1917, the U.S. War Industries Board asked American women to help their “men […]

Although modern medicine has made tremendous advances in many areas, even mapping the human genome, there remain aspects of human health that continue to elude our full understanding. Alien hand syndrome is one of these puzzles- with its sufferers having one of their hands, usually the non-dominant one, acting as if it has a mind of its own. Many of […]
