Last month, a NASA spacecraft and its accompanying spent rocket stage slammed into the surface of the Moon's south pole, in the Cabeus crater. A few weeks later, as everyone was teeming with anticipation, the much-awaited announcement finally came – water existed on the Earth's satellite. Spectrograph... |

As anyone who has ever cooked can tell you, adding a little bit of flour in a bowl of water yields a spectacular phenomenon. The fine particles in the powder quickly diverge from the spot where they were originally dropped, in a manner similar to that of an explosion. Explanations as to why this happens have eluded p... |

For a great many years, scientists have believed that the oceans on our planet were formed from water vapors emitted during volcanic eruptions that condensed and fell to the ground over millions of years. But a scientist now proposes that this might not have been the case. He argues that water is not something that o... |

In a new series of studies, experts have determined that planting new trees, and creating forests, in areas that previously had none, can have negative, long-term side-effects on the water flows of the region. This type of research is extremely important for policymakers, especially considering that the fight against... |

Most people know that being in the heat can be bad for their health, and that is why they usually drink water before they go outside in the Sun, and take some with them as well. But have you ever met a person that drinks about seven liters of water before going out? Of course not, because it's nearly impossible.... |

In an interesting, new development, scientists have demonstrated for the first time that strontium ions congregate on the surface of water. The behavior of this type of ions, which are, in fact, divalent cations (two electrons missing), has been a subject for scientific debate until now, because theoretical models an... |

For many decades, the basic principles of producing rocket fuel have remained the same. Boosters are still fueled by mixtures of liquid hydrogen and liquid oxygen, chemicals that burn hot and fast enough to provide the massive thrust force several tens of tons of metal require to be lifted off the ground. This year, ... |

Like anything else done in China recently, the envisioned South-to-North Water Diversion Project will take place on a gargantuan scale. Essentially, it goes something like this: the northern parts of the country have little water reserves, while the South has some that it can spare. Therefore, a route of channels cov... |

Until not long ago, experts believed that the Moon was not the most likely place in the solar system where one would find liquid water. In fact, measurements of lunar soil samples, brought back by Apollo-mission astronauts, have shown that, on average, only about 32 ounces of water could exist in theory within a ton ... |

Drink water when you work out – this must be the one line that trainers say more times perhaps than any other. There is very sane reasoning behind it too, because we lose a lot of water and essential minerals by sweating, and we have to replace them somehow for the optimal performance.

For a long time, the United States military has been in doubt over how to most efficiently distribute water to its soldiers when they set out on two- or three-day missions. The solution they came up with in 1982 is called the Shapiro equation and has been used to this day to calculate just how much water a military m... |

Experts have known for a very long time that water is a very peculiar liquid.

When the Phoenix Mars Lander first set its metallic feet on the surface of the Red Planet, it almost instantly struck gold, or, even better, ice.

In their search for life on other planets outside the solar system, astronomers may as well take into account another limiting factor.

Give water, on the other ... |
