Over the centuries, the idea that hypnosis may be a potent medical tool has been widely circulated. However, accounts are filled with tales of quackery, of so-called practitioners that brought a bad fame to the word, similar to what happened to acupuncture. In spite of the efforts some people made to discredit the te... |

Biologists and other scientists have been studying the origins of life as we know it for a very long time, and, for good or for worse, they have an idea about the chain of events that led to the development of the first organisms, and eventually to the emergence of the more complex species. But now, experts at an Aus... |

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,... |

There is no doubt in anyone's mind that we are currently in a warm Earth period. And we're not talking here about the climate change-type of warming, but of the planet's natural warming/cooling cycle. The current trend began some 11,700 years ago, and that is why Danish researchers looking into the his... |

For California, heat waves are nothing new. The state is constantly bathed by the sun, and benefits from an arid and hot climate. But, from time to time, massive heat waves come over it, such as the one in 2006, which killed 600 people, 5,000 cattle and 70,000 poultry in one swift blow. This all happened between mid ... |

Freak waves are phenomena of nature difficult to explain even for oceanographers. They are essentially oceanic surface waves much larger than those around them. That is to say, they are larger than the mean height of the third waves in a wave group, which entails that they may not be the largest in the ocean per se. ... |
