University of Texas at Austin Researchers at The University of Texas at Austin have devised a new method for enriching a group of the world's most expensive chemical commodities, stable isotopes, which are vital to medical imaging and nuclear power, as reported this week in the journal Nature Physics. For many isotopes, the new method is cheaper than existing methods. For others, it is more environmentally friendly. A less expensive, domestic source of stable isotopes could ensure...

Cooking Up Our Solar System, What's The Recipe?
2013-02-21 05:05:42

April Flowers for redOrbit.com - Your Universe Online A research team from the University of California, San Diego is hoping to learn how our solar system evolved by studying the origins of different isotope ratios among the elements that make up today´s smorgasbord of planets, moons, comets, asteroids, and interplanetary ice and dust. The scientists are led by Mark Thiemens, Dean of the Division of Physical Sciences, who has worked on this problem for over three decades. Most...

Supernova Shock Wave And Its Role In Solar System Formation
2012-08-03 09:04:16

April Flowers for redOrbit.com - Your Universe Online It has long been thought that our Solar System was formed by the shockwave from a supernova explosion. According to this theory, the shockwave also injected material from the exploding star into a cloud of gas and dust. The newly polluted cloud formed the Sun and its surrounding planets. A new study by Alan Boss and Sandra Keiser of the Carnegie Institution for Science, published in The Astrophysical Journal Letters, provides the...

Law enforcement may have a new crime-solving tool, courtesy of geoscientists. About five years ago, scientists coined the word "isoscape" to describe a new kind of map: a spatial distribution of stable isotope ratios (from elements such as carbon, hydrogen, oxygen, nitrogen and strontium) in different parts of the world, based on known ways that these isotopes behave in the environment. Different isotopes tell different stories – carbon can help identify diet, whereas hydrogen and...

MOUNTAIN VIEW, Calif., Aug. 19 /PRNewswire/ -- Los Gatos Research (LGR), the leading innovator of cavity-enhanced laser-based instrumentation for analyses of gases and liquids, today announced the availability of the second-generation Liquid-Water Isotope Analyzer (LWIA). "Our new LWIA is the fastest, most accurate analyzer for measuring the isotopes of oxygen and hydrogen in liquid water on the market today," said Douglas Baer, Ph.D., president of Los Gatos Research (www.LGRinc.com). "In...

U.S. and British scientists have determined nickel might be a useful isotopic marker to trace the origins of single cell organisms that produce methane. Our data suggest significant potential in nickel stable isotopes for identifying and quantifying methanogenesis on the early Earth, said Vyllinniskii Cameron, a recent Penn State graduate and now a post-doctoral fellow at the University of Bristol. Little is known about the actual timing of the evolution of methane producing organisms or...

Nickel, an important trace nutrient for the single cell organisms that produce methane, may be a useful isotopic marker to pinpoint the past origins of these methanogenic microbes, according to Penn State and University of Bristol, UK, researchers."Our data suggest significant potential in nickel stable isotopes for identifying and quantifying methanogenesis on the early Earth," said Vyllinniskii Cameron, recent Penn State Ph.D. recipient in geosciences and astrobiology and currently a...

Researchers at University of Utah reported Monday that a single strand of  hair can reveal a history of which areas within the United States a person has been living or spending time.The scientists compared variations in isotopes of hydrogen and oxygen found in strands of hair to those of tap water in various areas of the country. They found the isotopes corresponded, and were able to use this information to determine a person's location during recent weeks to years.Isotopes are forms of...

Star is Found to be 13.2 Billion Years Old How old are the oldest stars? Using ESO's VLT, astronomers recently measured the age of a star located in our Galaxy. The star, a real fossil, is found to be 13.2 billion years old, not very far from the 13.7 billion years age of the Universe. The star, HE 1523-0901, was clearly born at the dawn of time. "Surprisingly, it is very hard to pin down the age of a star", the lead author of the paper reporting the results, Anna Frebel, explains. "This...
