Crew members Christopher Columbus left behind after his second voyage to the Americas are telling tales of their past, U.S. researchers said. A team from the University of Wisconsin-Madison is examining the teeth from three sets of remains excavated nearly 20 years ago from the site of La Isabela -- the town Columbus founded in the Dominican Republic more than 500 years ago. Researchers said carbon isotope ratios provide evidence of diet at the time a child's adult teeth emerge, oxygen...

Results critical to interpretation of GENESIS spacecraft samples of the sun A strange mix of oxygen found in a stony meteorite that exploded over Pueblito de Allende, Mexico nearly 40 years ago has puzzled scientists ever since. Small flecks of minerals lodged in the stone and thought to date from the beginning of the solar system have a pattern of oxygen types, or isotopes, that differs from those found in all known planetary rocks, including those from Earth, its Moon and meteorites from...

Hundreds of patients face delays to vital scans for cancer and other diseases due to a "severe shortage" of imaging chemicals, an expert has warned. A global shortage of medical isotopes used in scans of hearts, bones, kidneys and some cancers will cause delays and cancellations across the UK in the coming weeks. British hospitals are currently receiving less than 50% of expected supplies and rations are expected to drop even further, the experts warned. The isotopes are used in more...

By Pratik Joshi, Tri-City Herald, Kennewick, Wash. Jul. 16--Benton County Commissioner Claude Oliver hopes to build on the discussions he recently had in Chicago to promote nuclear energy and medical isotopes. Oliver led a Tri-City delegation to the annual convention of RainbowPUSH Coalition at the invitation of the Rev. Jesse Jackson to highlight the benefits of developing nuclear industry, particularly in the face of an impending energy crisis. The Tri-Cities has the necessary...

A recent study has shown that tiny slivers of diamond forged on an infant Earth may contain the earliest traces of life. The crystals contain a form of carbon often associated with plants and bacteria. The researchers caution that their results are not definitive proof of early life but do "not exclude" the possibility. "We're all a little sceptical," said Dr Martin Whitehouse of the Swedish Museum of Natural History and one of the authors of the paper. If the study is proven to be true then...

CSIs now have a new tool in their belt: the chemical signatures left by local drinking water in human hair. Scientists at the University of Utah have found that the ratios of different forms of hydrogen and oxygen in local drinking water vary from region to region across the country. These elements are incorporated into the hair as it grows. Traces in the hair can show where a person has recently lived or traveled, and could help police track the recent movements of criminals. "You are...

Planetary scientists on both sides of the Atlantic have tracked down a rare molecule in the atmospheres of both Mars and Venus. The molecule, an exotic form of carbon dioxide, could affect the way the greenhouse mechanism works on Venus. The discovery is being announced today at the annual meeting of the American Astronomical Society's Division of Planetary Sciences in Orlando, Florida. Its presence could affect the way the greenhouse mechanism works on Venus. The mystery began back in April...
