Nobel Prize Winner Barry J. Marshall in Part Proved What Causes Ulcers by Ingesting the Bacteria He Thought Was Causing Them

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 […]

WWII Files: Pigeon-Guided Missiles and Bat Bombs

This was no different during the early years of modern medicine when one practice in particular, human […]

The Man Who Held Off Six Enemy Tanks and Several Waves of Infantry for an Hour By Firing on Them While Standing Atop a Burning Tank

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 […]

Why Nuclear Bombs Create Mushroom Clouds

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 […]
