Females Store Sperm For Decades

According to Dr. Klaus Reinhardt from the University of Sheffield U.K.,they found that females do this by lowering the metabolic rate of sperm, so it can survive in their bodies almost indefinitely.
In one extreme example, biologists have shown that queen ants fertilise their eggs with sperm they’ve stored for up to 30 years. Normally, once it’s outside the male’s body, it doesn’t survive for long. The findings could explain why, in reproductive medicine, sperm samples aren’t necessarily the best way to predict if someone can father children or not.

The Pitch Drop Experiment

Geek Alert! How long is the longest continuous running science experiment? Eighty-five years, so far. It all began in 1927 when Thomas Parnell, a physics professor at the University of Queensland in Australia, set out to show his students that tar pitch, a derivative of coal so brittle that it can be smashed to pieces with a hammer, is in fact a highly viscous fluid. It flows at room temperature, albeit extremely slowly. Parnell melted the pitch, poured it into a glass funnel, let it cool (for three years), hung the funnel over a beaker, and waited.
Eight years later …a dollop of the pitch fell from the funnel’s stem. Nine years after that, another long black glob broke into the beaker.
