In a new paper published in the latest issue of the journal Astrobiology, experts explain that life is theoretically possible on large swaths of the Martian surface. Granted, not all areas are habitable, but some may support life. This discovery has several important implications, including the fact that it may info... |

With a Google search on anything related to December 21, 2012 returning tens of millions of hit, it's easy to see that many people are concerned that the world will somehow end at that time. NASA experts say that such a catastrophe will not be caused by the proposed planet Nibiru.
Nor will a potential end of... |

The scientist who first pointed out that global warming is a real phenomenon is now saying that the 2-degree warming target that we should strive to avoid is insufficient to prevent climate change. It is widely believed that warming needs to be kept under 2 degrees Celsius in order for the Earth to be safe.
