'Supersize' lions roamed Britain
From BBC-Science:
It is thought the ancient lions would not have had manes
Giant lions were roaming around Britain, Europe and North America up to 13,000 years ago, scientists from Oxford University have found.
Remains of giant cats previously discovered were thought to be a species of jaguar or tiger but after DNA analysis they were proved to be lions.
They were 25% bigger than the species of African lion living today, and had longer legs to chase their prey.
They would have lived in icy tundra with mammoth and sabretooth tigers.
It is thought these animals would hunt over longer distances, and their longer legs would help them chase down their prey as opposed to the modern-day species which tends to ambush its victims.

World's tiniest frogs
This is likely the smallest frog species in the world, discovered in the Andes Mountains' upper Cosnipata Valley in Peru.From National Geographic:
"The most distinctive character of the new species," scientists write in the February issue of the journal Copeia, "is its diminutive size." Females grow to 0.49 inch (12.4 millimeters) at most. Males make it to only 0.44 inch (11.1 millimeters).
What's most surprising is that the frog lives at such high elevations, said study co-author Alessandro Catenazzi, a postdoctoral researcher at the University of California, Berkeley. In general, larger animals are found at greater heights.
