The loss of the Siberian unicorn shows just how vulnerable some animals can be to environmental change that can impact on their food supply.
What can we expect from our future climate after looking at the 'Hothouse Earths' of the past?
A 20-year-old experiment is testing whether filling the Arctic tundra with animals could keep carbon trapped in the ground.
Humans butchered a rhino in a remote part of the Philippines 700,000 years ago, but who were they and how did they get there?
Why was one gene mutation that affects hair, teeth, sweat glands and breasts ubiquitous among ice age Arctic people? New research points to the advantage it provided for ancestors of Native Americans.
Bed bugs make us shudder and cringe. So arm yourself with the courage to learn about the biology and successes of Cimex lectularius -- as well as the ways to get rid of it.
Fossils of a whale thought to be found only in southern waters have been discovered at two sites in the northern hemisphere.
The last ice age locked atmospheric carbon dioxide into oceans, which has major implications for how the oceans and carbon dioxide may be linked in the future.
18,000 years ago a volcano in Antartica began erupting – and didn't stop for 192 years.
Beeches are 'non-native' to Scotland because they got there less than 7,000 years ago. No, really.

Almost half a million years ago a huge flood started breaking the apart the land bridge that joined England and France.
During a Q&A discussion about climate change, Tasmanian Senator Jacqui Lambie said it was four degrees hotter 110,000 years ago. Is that right?

The Game of Thrones universe could fight off those long winters – if it had an industrial revolution.
Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.
