For centuries, scientists have recognized that the world's oceans are the final frontier in biology. For the wide variety of fish and other marine species we know, many believe that we've only begun to scratch the surface of what lies under the surface. The deep ocean was long believed to be the least-explo... |

Millions of years ago, as Antarctica was covered by plains and mountains, not ice, lakes adorned its surface, as they do on all other continents. As the weather cooled, and ice began to form, the majority of these lakes solidified, and became a part of the thick ice sheet currently covering the Southern Continent. Bu... |

For nearly 200 million years, dinosaurs reigned supreme. They were spread out across most locations on the planet, and there were no creatures that could challenge their domination except, of course, other dinosaurs. Yet, some 65 million years ago, an asteroid impact managed to wipe them all out. Some studies suggest... |

Most animal species, if taken from the wild into the heart of cities, lose their abilities to stay “cool,” and never adapt to a life of roaming free among cars, buses and office buildings. However, this doesn't seem to be the case with a turtle species in Australia, which apparently thrives in an urb... |

Naturalists and biologists warn those suffering from arachnophobia that this autumn may be a thing of nightmares. On account of excellent breeding conditions and suitable climate, much more spiders and daddy longlegs (crane flies) will be spawned. Last autumn was very rainy, so crane-fly larvae had sufficient decayin... |

Over the past century or so, the spread of invasive species in new habitats has increased in proportions and severity. With the advent of modern transportation, it has become a lot easier for pests or new species to enter habitats they were not designed to function into. If they manage to adapt to the new conditions,... |
