Scientists have also known that after dung beetles collect the dung, they do a little dance on top of it before moving it in a straight line to their destination.

Eleven thousand years ago, one saucy canine got busy and, as can happen with unprotected sex, gave its partner a venereal disease, although uniquely, this VD was cancerous. Over the course of the intervening millennia, that second dog, its partners, and its partners’ partners, all did what dogs eventually do, each spreading the disease, which has continued to retain some […]

In modern times, many believed that this was nothing more than an old wives’ tale.

Mike A. asks: What is the difference between bees, wasps, and hornets? There are many similarities and differences between our little wing-whipping friends. For starters, all can sting you. That said, you may derive some solace in the fact that when certain of them sting humans, they die- not so when they sting many other animals. The barbed stingers on […]

Shawn asks: Do cow farts really significantly contribute to global warming? There are currently approximately 1.3 to 1.5 billion cows grazing, sleeping, and chewing their cud at any given time on planet Earth.

The date was April 3, 1919. The location was the South Side Pavilion in sunny Jacksonville, Florida. The occasion was a much-hyped competition of gastronomical strength between Ping Bodie, the five foot eight and 190 pound New York Yankee outfielder, versus the “world’s greatest eater,” an ostrich named Percy. They were to engage in a spaghetti-eating contest to determine, once […]

Despite what you learned in grammar school, there are way more than four states of matter. One possible new one, disordered hyperuniformity, was recently found in the weirdest place – the eyes of chickens. Classical States of Matter To better understand an exotic state of matter like disordered hyperuniformity, it may be helpful to review the characteristics of the classical […]
