It's the smallest cat in the Americas, occupying the smallest area of land.

Listed as vulnerable to extinction, the güiña wildcat of Chile has lost much of its natural home as forests are chopped down or converted to farmland, according to BBC.

And, like many carnivores, it's at risk from human persecution over fears it might kill livestock.

Scientists have found an explanation for how flowering plants became dominant so rapidly in ecosystems across the world -- a problem that Charles Darwin called an 'abominable mystery'. Kevin Simonin and Adam Roddy, found that flowering plants have small cells relative to other major plant groups and that this small cell size is made possible by a greatly reduced genome size, according to Science Daily.

A turkey-sized dinosaur that once roamed the rift valley 113 million years ago has been discovered according, to Daily Mail`.

It appears the plant-eating dinosaur became trapped in a log jam where it died in pain and became immortalised.

The new find sheds light on the diversity of the small, bipedal herbivorous dinosaurs called ornithopods.

The partial skeleton named Diluvicursor pickeringi or Pickering's Flood-Running dinosaur was found in sea cliffs. 

'Diluvicursor shows for the first time that there were at least two distinct body-types among closely related ornithopods, said lead author Vertebrate Palaeontologist Dr Matt .

Researchers have made another discovery at the cellular level to help understand the basic processes of all life on our planet -- this time within the unusual bacteria that has lived inside cicada insects since dinosaurs roamed Earth, according to Science Daily.

During the past 70 million years, the bacteria underwent extreme adaptations to live within the insects' bodies, losing between an estimated 95 to 97 percent of their genes and resulting in some of the smallest genomes known to any organisms. In the process, they lost the ability to live anywhere outside of cicadas.
