How the darkness and the cold killed the (non-avian) dinosaurs

Now we have a computer simulation of how the afterward effects of famous Chicxulub asteroid (estimated to be 10 km/6.2 mi) wide) killed the non-avian dinosaurs (and also a wide range of other species). On January 13, 2017, an article titled “Baby, it’s cold outside: Climate model simulations of the effects of the asteroid impact at the end of the Cretaceous”, published by the Climate scientists of Potsdam Institute for Climate Impact Research (PIK), revealed a detailed model of what happened to the atmosphere and the climate after the Chicxulub impact.

What would happen if humans became extinct?

In the last few thousand years, humans have had a powerful impact on Earth. Within a geological blink of an eye, we exploded out of Africa to colonize virtually every inhabitable space on the planet. We dammed the rivers, we domesticated animals, deforested many areas, changed the chemistry of atmosphere and he seas… list goes on. But, what would happen if humans suddenly become extinct in the future?

Top 6 largest living fish species

Here are the top six largest living fish species (within around 33,100 described species).

But, first of all, what is a fish? At first, it looks like an easy question, but in fact it is not. There are a wide range of animals we call “fish”, so it is not easy to define what makes a fish “a fish”. A general description: “a fish is any member of a paraphyletic group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits” (wikipedia).

Nile Crocodiles Have Been Found in Florida

Four Nile crocodiles have been found in Florida by scientists from the University of Florida. Between 2002 and 2004, the researchers have studied populations of crocodiles in the state. Previously, using DNA analysis, they found three Nile crocs: one was a foot long hatchling sitting on a porch in Miami. Another was found on the property of a private zoo in Homestead, and a third, also in Homestead, a 10-pound (4.5 kg) female, was captured in a public park.
