 According to the study, nearly 58 percent of all tree species are single-country endemics, meaning they only occur naturally within the borders of a single country. The highest totals for endemic tree species are found in Brazil, Colombia, and Indonesia, which makes sense given the overall biodiversity found in their native forests. The study's authors write, "The countries with the most country-endemic tree species reflect broader plant diversity trends (Brazil, Australia, China) or islands where isolation has resulted in speciation (Madagascar, Papua New Guinea, Indonesia)."

I simply wanted to smoosh it till it popped! Cuteness aggression is a feeling that individuals get when they desire to smash a lovely dog.

While Lamborghinis are commonly associated with affluent and famous individuals who purchase such a vehicle as a sign of prestige, Lamborghinis also serve some extremely beneficial reasons. One application for these vehicles among Italians is the transfer of donated blood and organs. Because there are time limits between collecting donated blood and organs and delivering them to a suitable storage facility, it seems to reason that they would chose a quick automobile for this duty. Lamborghinis are also used as police cars in Italy and the United Arab Emirates. Because of the speed of the autos, this is another reason that makes sense.

The Nabataeans, like many other ancient peoples, revered the sun as a source of light and life, and Petra's design reflects that reverence.

A fun fact is that Galileo and Shakespeare were both born in the same year (1564). The English dramatist was reaching the end of his career when Galileo pointed his telescope to the night sky. But he wasn't quite ready to lay down his pen: his late drama Cymbeline contains what might be a reference to one of Galileo's most important discoveries—the four moons around Jupiter. The deity Jupiter descends from the skies in the last act, and four ghosts dance in a circle around him. It may be a coincidence, or, as I argue in my book The Science of Shakespeare, it could be intentional.
