Bed bugs have existed since the time of the dinosaurs.

Bed bugs are near impossible to get rid of and can spread faster than water-cooler gossip. But that might also be why they've managed to stick around for so long. Scientists believe that the bugs have existed since the time of the dinosaurs, coming onto the scene about 115 million years ago, according to a 2019 study in Current Biology.

"To think that the pests that live in our beds today evolved more than 100 million years ago and were walking the earth side by side with dinosaurs was a revelation," said researcher Mike Siva-Jothy. "It shows that the evolutionary history of bed bugs is far more complex than we previously thought."

Pineapple works as a natural meat tenderizer.

The fruit is packed with the enzyme bromelain, which breaks down protein chains, making it an ideal marinade for meats when you don't have a lot of time. But for the same reason, pineapple does not work for jams or jellies, since the enzyme breaks down gelatin as well. The bromelain is so strong that pineapple processors have to wear protective gloves, otherwise over time the enzyme eats away at the skin on their face and hands, leaving dry skin and small sores.

Goosebumps are meant to ward off predators.

Why do we get goosebumps? In this physiological reaction, small muscles attached to individual body hairs contract, which leads the hair to stand on end. We inherited this ability from our ancestors in part as a way for our (then) coat of body hair to capture air beneath it and in that way retain heat. But, as George A. Bubenik, a physiologist and professor of zoology at the University of Guelph in Ontario, Canada, explained to Scientific American, it also caused our ancestors to appear bigger than they were, helping to ward off predators when they were frightened or on the defense. With modern humans having less body hair, goosebumps no longer cause us to look that much more intimidating.

The moon has moonquakes.

Just as earth has earthquakes, the moon has—you guessed it—moonquakes. Less common and less intense than the shakes that happen here, moonquakes are believed by U.S. Geological Survey (USGS) scientists to occur due to tidal stresses connected to the distance between the Earth and the moon.Just as earth has earthquakes, the moon has—you guessed it—moonquakes.

The heads on Easter Island have bodies.

The iconic stone heads protruding from the ground on Easter Island are familiar to most, but many don't realize what lies beneath the surface. In the '10s, archaeologists studying the hundreds of stone statues on the Pacific Island excavated two of the figures, revealing full torsos, which measure as high as 33 feet.
