Taking inspiration from the yellow fattail scorpion, which uses a bionic shield to protect itself against scratches from desert sandstorms, scientists have developed a new way to protect the moving parts of machinery from wear and tear. A report on the research appears in ACS' journal Langmuir. Zhiwu Han, Junqiu Zhang, Wen Li and colleagues explain that "solid particle erosion" is one of the important reasons for material damage or equipment failure. It causes millions of dollars of damage...

When the water in the Mississippi River rose to 58 feet with a forecast of 60 feet or higher in May 2011, the emergency plan to naturally or intentionally breach the levees, established over 80 years prior, was put in motion. The flood of 1937 did top the frontline levee and water passed into and through the New Madrid Floodway, but being floodfree since then caused area landowners to oppose the plan being put into action. "After a delay due to a legal appeal from area landowners, the U.S....

Image 1 - Increased Ice Loss Resulted In Greater Greenland Bedrock Lifting

A higher-than-normal 2010 melting season sped up the melting of ice in southern Greenland, causing sizable portions of the island's bedrock to rise somewhere about a quarter of an inch more than usual, an Ohio State University (OSU) researcher said on Friday. According to an OSU press release, Michael Bevis, Ohio Eminent Scholar in Geodynamics and professor in the OSU School of Earth Sciences, said that 50 GPS stations spread across the coast of Greenland normally "detect uplift of 15 mm...

Melting Permafrost Amplifies Global Warming Effect
2011-12-01 06:15:21

According to a survey published in the November 30 issue of the journal Nature, melting permafrost in the northern climes is releasing large amounts of methane and carbon, amplifying the global warming effect. When permafrost melts, long dormant microbes come alive and break down the organic matter underneath the layers of frozen soil creating methane. Methane gas has 2.5 times the effect on the atmosphere than carbon dioxide, creating a greater warming effect. The survey, led by Edward...

Something's up with the weather in Namibia, say geoscientists Kyle Nichols of Skidmore College in Saratoga Springs, N.Y., and Paul Bierman of the University of Vermont in Burlington, Vt. Nichols and Bierman should know. They're just back from the western mountains and coastal plain of this sparsely populated African country. Usually, western Namibia is a dusty place where the stream beds are sand and the "lakes" are nothing more than flats of dried mud. Not now. This year, rivers...

By Joshua E. Brown, University of Vermont Every mountain and hill shall be made low, declared the ancient prophet Isaiah. In other words: erosion happens. But for the modern geologist a vexing question remains: how fast does this erosion happen? For more than a century, scientists have looked for ways to measure and compare erosion rates across differing landscapes around the globe"”but with limited success. "Knowing the background rate of erosion for a place is extremely important,"...

Researchers from the Polytechnic University of Catalonia (UPC) have developed a method for evaluating the vulnerability of coastal regions to the impact of storms. The method, which has been applied on the Catalan coastline, shows that one-third of the region's coasts have a high rate of vulnerability to flooding, while 20% are at risk of erosion. "Until now there was no tool for evaluating coastal storm vulnerability that could quantify the processes and the probabilities of these events...

Desert greening
2013-04-25 16:10:03

Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...

Theodore Roosevelt National Park

Theodore Roosevelt National Park is located in western North Dakota in the United States. The park contains 70,446 acres of land that is separated into three distinct badland areas known as the Elkhorn Ranch Unit, the South Unit, and the North Unit. Roosevelt  first visited the area in 1883, while hunting for bison, and is said to have “fallen in love” with the badlands. After investing a large sum of money into the Maltese Cross Ranch, Roosevelt had his own cabin built, which he later...

Badlands national Park is located in the southwest region of South Dakota. It holds 242,756 acres of land, with 64,144 acres comprising a protected wilderness area. The park was designated as a national monument in 1929 and established in 1939, but attained national park status in 1978. The Stronghold Unit area of the park is managed by the National Park Service and the Oglala Lakota tribe and holds many sights including those used for Ghost Dances in the 1890’s, a bomb and gunnery range...

A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
