Made-to-order Isotopes Hold Promise on Science's Frontier

Designer labels have a lot of cachet--a principle that's equally true in fashion and physics. The future of nuclear physics is in designer isotopes--the relatively new power scientists have to make specific rare isotopes to solve scientific problems and open doors to new technologies, according to Bradley Sherrill, a University Distinguished Professor of physics and associate director for research at the National Superconducting Cyclotron Laboratory at Michigan State University.

New Frontiers in Science

The future of nuclear physics is in designer isotopes, the relatively new power scientists possess to make specific rare isotopes that solve scientific problems and open doors to new technologies, according to Bradley Sherrill, PhD, a University Distinguished Professor of physics and associate director for research at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University (MSU) in East Lansing.

Nuclear explosions could be key to spotting fake paintings

Nuclear explosions, like this U.S. military test in the Marshall Islands in 1946, released isotopes into the environment, permeating the soil and ending up in natural oils used to make paint.

Nuclear fallout used to spot fake art

Scientists and art historians have developed what they say is a foolproof way of identifying forged works of art. They can distinguish between art created before 1945 and that produced after that date by measuring levels of the isotopes caesium–137 and strontium–90. These isotopes do not occur naturally but are released into the environment by nuclear blasts.

Antarctica Once Abutted Death Valley

Science News has a story of strange bedfellows. It seems that Antarctica was once adjacent to what is now the American Southwest, some 800 million years ago. Earth's continents then formed a supercontinent called Rodinia, predating Pangaea by some 550 million years. "...the ratios of neodymium isotopes in the ancient sediments in the Transantarctic Mountains are the same as those in what was then Laurentia, says Goodge. Also, the hafnium isotope ratios in the 1.44-billion-year-old zircons found in East Antarctica match those of the zircons found in the distinctive granites now found primarily in North America. Finally, the researchers note, the ratios of various isotopes and elements in a basketball-sized chunk of granite found in East Antarctica — a chunk ripped by a glacier from bedrock now smothered by thick ice, the team speculates

Nanotech makes radioactive sensors obsolete

"Green" smoke-alarm ionizers using field-emission from nanotubes instead of radioactive isotopes could eliminate a source of dirty-bomb material, according to recipients of a U.S. Small Business Innovation Research (SBIR) contract sponsored by the Homeland Security Advanced Research Projects Agency.

Nuclear Explosions Key To Spotting Fake Art

Socguy writes "A Russian art curator, Elena Basner, is claiming to have a foolproof method for determining whether or not particular paintings have been created since 1945. She claims that isotopes released into the environment by man-made nuclear explosions have found their way into types of the natural oils used to make paints."
