Due to concerns over air pollution and health risks, this type of gas was slowly phased out starting in the […]

Cleo McVicker, just 21 years old, was tasked with selling off the company’s remaining assets, which at the time comprised mainly of powdered hand soap. Once that was done, the company would be too. Cleo, however, managed to turn […]

The Tunguska event occurred around 7:00 a.m. local time on June 30, 1908 near […]

Today I found out why your nose gets runny when it is cold. On an average day, a typical person’s nose will produce about one quart of mucus/fluid (just under one liter). Most all of this snot generally gets passed back into your throat and swallowed, often without you even really being too conscious of it. When you’re breathing cold […]

Today I found out how to read an EKG. While some people might say that kind of skill should require 13 years of preparatory school, four years of college, four years of medical school and a specialty in cardiac electrophysiology, I say…Pshaw! It’s not rocket science! If it were, there would be more combustion and potential for speedy projectiles gone […]

Today I found out why leaves change color in the fall. The primary thing that triggers the changing of colors in leaves is the length of day. However, moisture and temperature play a role as well. For instance, an extreme drought in the summer can delay somewhat the changing of the colors in fall. Why this is the case is […]

Today I found out what exactly is going on with the heart during a heart attack. We’ve all seen the 70 year old man on TV who suddenly clutches his chest and yells “Oh, my chest!!” and then falls over dead. Seems like a relatively easy way to die, certainly better than massive burns over your body then dying three […]

Today I found out what makes your eyes red in flash photographs. Simply put, that crazy zombie look people tend to get, as if they are about to use you as a pre-lunch snack, has to do with how light from a camera flash reflects off the eye, and the specific wavelengths at which it tends to do this. It […]
