The novel coronavirus has infected more than 26.35 million people, with just four countries accounting for over 15 million cases. They are the United States, Brazil, India and Russia — the same four that have been at the top for months.

What’s Going On With the Sahara Desert?
Stretching 3.5 million square miles across northern Africa, the vast sand dunes and rocky plateaus of the Sahara cover more ground than the continental United States. Now, a pair of scientists is making a provocative claim that the world’s largest desert has expanded 10 percent since the early 20th century, effectively adding another Texas-sized chunk.

This river ecosystem hinges on thousands of drowned, rotting wildebeest
When we die, our bodies become the grass, and the antelope eat the grass. And so we are all connected in the great Circle of Life. Everyone knows that classic line from Disney’s “The Lion King”. Kids and parents might have been slightly less charmed by this variation: The wildebeest must cross the river to eat, and a whole bunch of them die in the process. And then everything in the river gets to feast on their rotting remains. Oh, and their bones continue to leech nutrients into the water even after fish and insects have devoured their flesh. Other organisms also eats the algae that grows on the bones. Basically, some wildebeest need to die, Simba.
