Scientists conducting a study of the ocean floor in the northeastern Pacific Ocean were surprised to discover 38 deep-sea limpets of the species Lepetodrilus gordensis attached to their submarine, Alvin. Previously, scientists thought that the pressure difference was a barrier against these species.
Such organisms ... |

A team of scientists from the Scripps Institution of Oceanography (SIO) in La Jolla, California, argues that hydrothermal vents and marine seeps can coexist in the same environment. The question as to whether or not that is the case has been a topic of discussion in the scientific community for a decade.
Many scien... |

If the newest research by Stanford University investigators is correct, then primitive life may have only arisen on early Earth during a rather brief geological time. The most recent study the team conducted on the origins of life on this planet revealed that it came very close to not emerging at all.
According t... |

On dry land, animals get their daily iron supplies from plants or read meat, but in the deep ocean things are a bit more difficult. Yet organisms living here need iron just as much as their more complex counterparts on the surface. A new study shows that hydrothermal vents are providing the chemical.These natural chi... |

A new series of discoveries is forcing investigators to reconsider established theories about how the world's oceans function. Recently, experts learned that the deep sea, long thought to be a world onto itself, in fact responds to changes that occur in the waters closest to the surface.The data indicate that th... |

A spacecraft orbiting the Red Planet may have discovered the first clear signs of a former hydrothermal environment on Mars. The mounds that indicated the presence of such a habitat were discovered on the slopes of a volcano, and were determined to be some three billion years old. The reason why this discovery is cri... |

A group of investigators has recently discovered the existence of a new species of archaebacteria inside the oceans, at a depth exceeding the height of Mount Everest. Temperatures and pressures here are way beyond anything we are accustomed to, yet somehow these creatures manage to endure.
This is the so-called h... |

New studies of the Martian surface have demonstrated that small habitats that could have been capable of supporting life may have existed on the Red Planet some three billion years ago. This conclusion comes from analyzing datasets beamed back by a NASA orbiter, which revealed the existence of mounds of light-colored... |

Investigations carried out using a NASA spacecraft have revealed that environments located in the Martian underground may be suitable for sustaining future colonists on the Red Planet. Data from the Mars Reconnaissance Orbiter (MRO) indicate that such area existed in the past, and hints that they may still be there t... |

The first ever investigation to look in close detail at the hydrothermal vents on the bottom of the Yellowstone Lake has determined that the structures are teeming with life. By definition, thermal vents are extremely hostile environments, mostly due to the fact that this is where hot gases from the Earth's mant... |

The recent expedition to the Mid-Cayman Rise, in the Atlantic Ocean, revealed new and amazing types of hydrothermal vents. These are structures that act as valves, releasing hot gas from the Earth's crust and mantle into the waters. They are located at very high depths, and are widely considered to be among the ... |

One of the most enduring theories in science is the one stating that life emerged from a primordial soup, a mix of chemicals that promoted over eons the creation of organic molecules, amino-acids, and eventually proteins. But some researchers are arguing at this point that it's time for this theory to be discard... |

Hydrothermal vents are some of the most peculiar structures in the world today, in the sense that they are the last places you'd expect to find life in. However, this is almost always the case. Naturally, no larger, more complex creature could withstand the heat and the harsh chemicals that are emitted from the ... |

Finding out how life appeared on our planet has been one of the main goals in Science for hundreds of years, but the answer has proven elusive and difficult to find out. This knowledge could help us determine the conditions that need to be met by an exoplanet or exomoon, for example, so that they can be considered vi... |
