In spite of being so common it's becoming annoying at times, sand is one of the most peculiar states of matter on the planet. While it may indeed not show, the stuff is able to behave like both a solid and a liquid at the same time, an ability that has made many physicists puzzle over which one of the two sands ... |

Scientists at the University of California in Berkeley (UCB) have managed to construct and sustain a large-scale, meandering river model in the laboratory, analyzing the most important factors that keep a flowing water healthy in the long run. Surprisingly, their reverse-engineering study has shown that sand is of th... |

Many experts currently consider that Mars' reddish hue is owed to rusted rocks, which were subjected to the action of the water that once covered the planet. This idea has been proposed and debated for a long time, but recent laboratory studies are beginning to infirm it, some experts say. The investigations hav... |

The linear dunes that have been observed on the surface of Saturn's largest moon, Titan, have made astronomers wonder how they came to be since day one. A number of theories on their formation was proposed, some with no merit, and others that actually stand to reason even now. To these ideas, Louisiana State Uni... |

Engineers have recently unveiled a plan that a few years back might have seemed like a joke – to build a wall to mark the spread of the Sahara desert, so that the dunes stop spreading over yet-unaffected ground. The problem appears all over the Saharan borders, as fields and families are being displaced by the ... |

The Spirit Martian rover is rising up to its name, NASA has announced recently. Despite being stuck up to its hubcaps in loose soil, the robot continues to do relevant science, taking pictures of its surroundings, and also of Troy, the patch of Earth that trapped it on May 6th. While engineers at the Jet Propulsion L... |

Sand is, perhaps, the single best material in the world. Millions of people live in it, and billions others interact with it as children or during holiday. And it's in this seemingly common, uninteresting, and sometimes deadly material that physicists believe they may have discovered hints about the fifth state ... |

With Spirit trapped in loose Martian soil since May 6th, engineers at NASA's Jet Propulsion Laboratory, in Pasadena, California, are working around the clock to mimic the conditions of the Mars Exploration Rover (MER) in their test facilities. Spirit and Opportunity are not the only MER components, as mission pl... |

After becoming stuck in the loose Martian soil of the Troy region, NASA's Mars Exploration Rover (MER) Spirit has recently taken its first pictures of its underside, in a move that has been simulated back on Earth, and with its twin robot Opportunity as well. At this point, researchers have no clue as to how the... |

The latest images sent by the Martian human-made explorers and orbiters show, in more detail, how the sand ripples scar the planet's surface in some regions, which allows scientists to build up on their existing theories related to their formation, or to come up with entirely new ones. Yet, as we lack more accur... |

Latest scientific discoveries point to the fact that coral reefs and sand are "allergic" to each other, in that they can't survive together. This is especially true for the coral reefs, which, once sand gets in their midst, die and cannot regenerate even after long periods of time. The find is essential in under... |

It is almost unbelievable that Mars, having barely any atmosphere, is able to create sand storms so powerful that they are visible from the surface of our planet. During these storms sand is being lifted high into the Red Planet's atmosphere and dropped only to stir up other dust particles present of the surface... |

You can't wait for that dream holiday when you just lay on the beach and catch sun. But watch out: too much wet sand or swimming in the sea can harm your stomach. A team at the University of Florida has discovered that by spending more time on the wet sand or in the water you increase the chances of getting germ... |

You know that sand comes in colors of yellow, white, or gray. Sometimes, if it's volcanic, also black. But what about a pink sand beach?As incredible as it may seem, they do exist. Harbour Island (Bahamas) is most renowned for its pale pink sand beaches, some over 3 miles (5 km) long and 50 to 100 feet (15 to 30... |

Born on the Californian beaches of Santa Monica and becoming an Olympic Game in 1996, the beach volley is a mixture between a good dose of strength, stamina and intuition. This is by excellence the summer sport, linked to the sand and sun. Moreover, many beaches have a net for playing this sport. It is played in pair... |

Granular materials are widely found both in nature and in industrial applications and although we use them every day, theoretical physicists and manufacturers are still puzzled by their weird behavior. Although they are solid, they refuse to comply to the laws of physics that govern the movement of solids and they d... |

Although they did not find out how Moses could separate the water of the Red Sea, they were able to do the same with a mass of sand grains, in an experiment which proves that no outside force is necessary to make identical molecules part.Scientists at the Rutgers University, New Jersey, proved that two identical pop... |

Landing at high enough speeds on sandy planets could sink the landing module deep in the sand layer, just like a rock diving into a pool. This is the conclusion of a new study that considered the problem of sand on other planets and how that could affect future manned missions to the Moon and Mars.Both Mars and the M... |

Mars Express sent back some interesting pictures of the Aeolis Mensae region on Mars, lying on a tectonic transition zone. The High Resolution Stereo Camera (HRSC) on board the space probe took snapshots of the wind-eroded features, like incised valleys and unexplained linear features.This region on the surface of M... |

The Atacama Desert is located in northern Chile and reaches a small part of southern Peru (South America), climbing up to 3,200 m (10,670 ft) altitude on an area of 181,300 square km (72,500 square mi). It spreads like a rather narrow stretch between the Pacific Ocean and the Andes mountains over a distance of 960 km... |

A long-standing mystery about Mars' sand dunes may have just been sold by scientists. The strange thing about the dunes is that they look as if they were created by winds, but there are no winds on the surface of Mars.Discovered in 1971 in pictures taken from space, above the surface, they look very similar to ... |
