Dung Beetles Love Human Poops

Why would anyone want to check out whose manure taste the best, I don't know. But it's exhilarating to know that we've won the interspecies dung contest (or rather, the first runner up).

Two entomologists, Sean Whipple and W. Wyatt Hoback set out to an organic cattle ranch where there were plenty of dung beetles crawling around. They took dungs from several animals native to North America (bison, cougar, moose), and also from animals from other parts of the world (tiger, lion, zebra), and presented them to the panel of dung experts.

Venus is the second planet from the Sun, and it's the hottest planet in our solar system. The surface temperature on Venus can reach 482 degree Celsius, high enough to melt lead and even zinc.

Marsupials Have Three Vaginas

Marsupials are mammals that give birth to relatively undeveloped young, and then raise them in pouches. Examples of marsupials that we all know are kangaroos, wombats, koalas, and Tasmanian devils. 

Apart from the pouch, they all have another thing in common: female marsupials possess three vaginas. 

WOW.

Water on Earth

How much water is there on Earth?

We often hear people say 70% of the Earth's surface is covered by water. Oceans and seas constitute the largest amount of water, roughly 96.5%. The rest exists in lakes, rivers, underground water sources, in our body, and in your pet.
