  Researchers have found that an atomic clock at the U.K.'s National Physical Laboratory (NPL) has the best long-term accuracy of any other clock in the world. Studies of the clock's accuracy show it is nearly twice as accurate as previously thought. The clock would lose or gain less than a second in about 138 million years. The NPL's CsF2 clock is a "caesium foundation" atomic clock, in which the "ticking" is provided by the measurement of the energy required to change a...

Japan's government plans to suspend all cattle shipments from Fukushima after the country's second-biggest retailer reported Sunday it had sold beef from cattle that ate nuclear-contaminated feed, Reuters reports. The country, which is still suffering the after-effects of the March earthquake and tsunami that devastated the region, has already dealt with a huge amount of contamination from products such as tea, milk, seafood and water; and the latest issue only adds to an already fueled...

Sandia researchers develop tiny laser that reduced power consumption 1,000-fold A matchbook-sized atomic clock 100 times smaller than its commercial predecessors has been created by a team of researchers at Symmetricom Inc. Draper Laboratory and Sandia National Laboratories. The portable Chip Scale Atomic Clock (CSAC) "” only about 1.5 inches on a side and less than a half-inch in depth "” also requires 100 times less power than its predecessors. Instead of 10 watts, it uses only...

(Ivanhoe Newswire) -- It has been 25 years since the Chernobyl nuclear disaster. Now, researchers say investigating that incident may help us better understand health consequences of nuclear accidents in the past, present, and future. Radioactive elements with a long half-life (the time it takes for half the sample to decay), especially caesium and strontium, will be prevalent in the environment for decades to come. Radioactive iodine, despite having a half-life of just eight days, can cause...

Experts said Friday that fires sweeping across Russia are threatening to re-release nuclear contamination from the Chernobyl disaster into the air, but not in levels dangerous to human health. According to Philippe Renaud, head of the environmental radiation laboratory at France's IRSN nuclear safety institute, radioactive cesium 137 from the 1986 explosion of Chernobyl nuclear power plant is locked up in the trees and dead leaves in the forest in certain areas of Russia, Ukraine and...

New material finds 'needle in a haystack,' shows promise for clean-up Not every object is food to a Venus flytrap. Like the carnivorous plant, a new material developed at Northwestern University permanently traps only its desired prey, the radioactive ion cesium, and not other harmless ions like sodium. The synthetic material, made from layers of a gallium, sulfur and antimony compound, is very selective. The Northwestern researchers found it to be extremely successful in removing cesium --...

The world's best caesium atomic clocks control Coordinated Universal Time (UTC), an atomic time scale on which the time zones used in everyday life are based. But also in navigation (GPS), astronomy, telecommunications, geodesy and physical fundamental research, accurate timing is of essential importance. Until recently, three of PTB's clocks belonged to the exclusive club of primary caesium atomic clocks. Now a fourth one, the caesium fountain clock CSF2, has joined in. This month, its data...

Cesium (or Caesium) is a chemical element with the symbol Cs and atomic number 55. Caesium is a soft alkali metal that is silvery-gold. It melts and liquefies at 83 degrees Fahrenheit and is one of only five metals that are liquid close to room temperature. Caesium is a metal that is most widely known for its use in atomic clocks. Cesium comes from the Latin word caesius meaning "˜bluish-gray'. It was discovered in 1860 by Robert Bunsen and Gustav Kirchhoff in Durkheim, Germany in mineral...
