When it comes to science, we think there’s a saying that is fairly applicable, “who dares, wins”. Fans of military history may recognise that as the motto of the Special Air Services (SAS). However, we feel scientists and researchers deserve to use it just as much, because sometimes they take risks too. Just ask Barry J. Marshall if you don’t […]

In addition to Mount Everest, the world’s tallest mountain by peak elevation standing at 8,848 meters tall, the range also features several other mountain peaks over 8,000 meters.

In May 1972 in a uranium enrichment plant in France, scientists examining ore from a mine in Gabon, West Africa, discovered that a natural nuclear reactor had spontaneously manifested in that region in the Earth’s primordial past, churning out approximately 100 Kw worth of energy continuously for a few hundred thousand years about 1.7 billion years ago.

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 […]

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 […]

Just over a century ago in the Mediterranean Sea in between Greece’s Peloponnese and the Isle of Crete, a sponge diver came across an amazing discovery: an ancient shipwreck from classical times, filled with pottery, jewels, wine and so many marble and bronze statutes that, upon surfacing, he “gabbled that he had found a heap of dead, naked women“. The […]

Ken Laha asks: How long would someone’s heart have to be stopped before you’d stop trying to revive them? The question of how long someone’s heart would have to be stopped for before you can safely say that regardless of what you do, you’re not going to be able to revive them is a very tricky question. It’s not as […]

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. While very dramatic, it’s also very untrue and an exceptionally bad idea if your goal is to get better. In […]

Did an exotic actress from Vienna, considered one of the most beautiful women in Hollywood in the 1940s, really invent wireless?

Myth: There are only three states of matter. I remember growing up and learning all about solids, liquids and gases. My science class in elementary school never talked about other states or phases of matter. As I aged and advanced in my education, I began learning about the other states. I naively assumed the new states of matter I was […]

Myth: Bumblebee’s shouldn’t be able to fly. 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. Now obviously this is false, since, well, bumblebees fly all the time and if every time a bee took off it was tearing physics […]
