Where sound goes to die, acoustic shadows are areas where sounds, from a certain direction and on a given day, will not penetrate; these acoustic phenomena occur either because the sound waves are absorbed, refracted or simply blown in a different direction. Relatively unnoticed in our modern, wired world, the phenomenon played a significant role in some of the most […]

The term “mind control” conjures up visions of someone manipulating people from the outside, such as an evil, brainwashing scientist or a supernatural being that takes dominion of a person just with the power of his mind. But since people don’t experience this in their daily lives, most don’t believe in mind control, and think of it as just a […]

Myth: Injecting medicine straight into your heart can be beneficial in some way. Ah, the dramatic scene that ends with an actor stabbing a needle straight into their heart, narrowly escaping death and magically curing whatever ailment just befell them.

There’s an oft repeated “fact” that the humble bumblebee defies all known laws of physics every time it flaps its tiny little bee wings and ascends to the sky.

Jesse asks: Why doesn’t wood melt? Jesse, I love this question. It seems like everyone knows things are solid at certain temperatures. If you heat them up, they will become a liquid. Heating it further will turn the substance into a gas. This elementary truism of science is every grade school students’ claim-to-fame at their science fair. At some point, […]

Lee Swanson asks: How does the human body create electricity? Fantastic question Lee. The shortest and most simple answer is- chemical reactions between different atoms and molecules within the body. If all that seems a bit vague, let me give you the long answer that inherently needs to get a bit “sciency”. O’ how I love long sciency answers, much […]

Ally asks: Is cellulite different from regular fat? In a sense, yes, but your question is a tad like comparing orange juice to the texture of an orange peel. While cellulite, also known as gynoid lipodystrophy, is often thought of as fat, that isn’t quite accurate. Fat is just a component of what causes cellulite, so perhaps more aptly cellulite […]

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 […]
