Forget warming - beware the new ice age

In the 1970s, leading scientists claimed that the world was threatened by an era of global cooling.

Prey not hard-wired to fear predators

Are Asian elk hard-wired to fear the Siberian tigers who stalk them" When wolves disappear from the forest, are moose still afraid of them?

No, according to a study by Wildlife Conservation Society scientist Dr. Joel Berger, who says that several large prey species, including moose, caribou and elk, only fear predators they regularly encounter. If you take away wolves, you take away fear. That is a critical piece of knowledge as biologists and public agencies increase efforts to re-introduce large carnivores to places where they have been exterminated. Berger's study is published in the latest issue of the journal Conservation Biology.

Earth has been hit and is constantly at risk of attack by interlopers from space. These are called "near earth objects" (NEOs). Major players are asteroids. Most burn harmlessly during their trip through the atmosphere. However, just as in the intensely mediocre films, Armageddon and Deep Impact, there is more than a zero chance that a large one will threaten earth in the near future.
