For animals, and humans, having bigger weapons can keep you from having to fight at all

In the battle for physical and sexual supremacy, human tactics haven’t progressed much past the lowly dung beetle. We may have brains capable of producing art and science, and we don’t spend our days hauling around dung (well, most of us don’t, anyway), but otherwise — not much has changed.

Melting Arctic sea ice doubles the chances of harsh winters in other parts of the world

When most people hear the term "global warming," they naturally think of air temperature. In reality, more than 90 percent of the warming caused by greenhouse gases happens in the oceans. Much of this warming takes place in the waters in and around the Arctic Ocean, leading to increasingly rapid melting of sea ice. A new study links this melting to cold, harsh winters that are becoming more common in parts of the world.
