A new type of material developed at the Massachusetts Institute of Technology is now revealed by chemist Daniel Nocera as a possible means to conduct water electrolysis processes at room temperatures with the input of relatively low electric currents. The material could be used to chemically store solar energy and ef... |

More than two months after NASA's Phoenix Mars Lander touched down on the north polar plains of the Red Planet, the pile of circumstantial evidence pointing towards the presence of water was put aside and replaced with the first clear analysis showing that water indeed exists on Mars. In a report published yeste... |

A water jet cutter is a tool able to slice into various solid materials with the help of a high speed jet containing a mixture of water and an abrasive material. Basically, water jet cutters rely on the same process that shaped most of the surface of the planet over the course of the past several billion years, water... |

Life appeared on Earth several billion years ago. Humans on the other hand, have been around for a little over 250,000 years. We know much about mathematics, physics, biology, etc., yet, one of the biggest mysteries today is related to how life first began on our planet. Now researchers say that diamonds might have b... |

Carbon dioxide laser resurfacing is currently by far the best solution when it comes to wrinkle removal techniques, giving overall better results than some of the latest invented procedures. Most of the time the technique is successful in clearing up the skin, and the side-effects are relatively harmless, generally c... |

Mars had liquid water on the surface in its distant past and quite a lot of it too, according to the high-resolution spectrometry images relayed back to Earth by the CRISM instrument on board NASA's Mars Reconnaissance Orbiter. CRISM revealed that there is a great abundance of clay minerals, which usually form i... |

As if global warming weren't bad enough as it is, researchers now say that the extra amount of carbon dioxide in Earth's atmosphere will strike us in one of the most painful ways possible: kidney stones. And this time it's not selective and it's most certain that some of the leaders of the G8 stat... |

Until now, several hundred planets have been found orbiting around nearby stars while the number of moons remained at a constant zero. It's not that they're not there, it's just that we can't see them with today's technology. To put it even simpler, the smallest planet ever found was a terres... |

Water surfaces, oceans and seas in particular, are natural sinkholes for carbon dioxide gas. And it just so happens that man made sure that Earth's atmosphere has plenty of carbon dioxide, which is absorbed into water, thus making it more acidic in the respective areas. This in turn affects the marine life such ... |

Pelicans look like birds hailing from prehistoric times. Truth is, they are precisely that.

Today, only 8 species of pelicans can be ... |

On Earth, there are two distinct ways through which water may erupt from beneath the surface into columns stretching as high as 45 meters or more.
