'Faster-Ticking Clock' Indicates Early Solar System May Have Evolved Faster Than We Think
2012-05-02 07:00:54

Our solar system is four and a half billion years old, but its formation may have occurred over a shorter period of time than we previously thought, says an international team of researchers from the Hebrew University of Jerusalem and universities and laboratories in the US and Japan. Establishing chronologies of past events or determining ages of objects require having clocks that tick at different paces, according to how far back one looks. Nuclear clocks, used for dating, are based on...

Individual atoms of a certain chemical element can be very stubborn when it comes to separation, mainly because techniques rely on a difference in chemical and physical properties – atoms are almost identical in both regards. However, if you peer closely enough into the atoms, there are subtle differences that can have very big effects. These "different" atoms, called isotopes, are heavily relied on in areas of medicine and nuclear energy and now researchers have proposed a novel way...

In a large natural disaster, such as the Haitian earthquake earlier this year, or in an unsolved homicide case, knowing the birth date of an individual can guide forensic investigators to the correct identity among a large number of possible victims. Livermore researcher Bruce Buchholz and colleagues at the Karolinska Institute are looking at victim's teeth to determine how old they are at the time of death. Using the Lawrence Livermore's Center for Accelerator Mass Spectrometry, Buchholz...

Trailing like a serpent's spine along the western coast of South America, the Andes are the world's longest continental mountain range and the highest range outside Asia, with an average elevation of 13,000 feet. The question of how quickly the mountains attained such heights has been a contentious one in geological circles, with some researchers claiming the central Andes rose abruptly to nearly their current height and others maintaining the uplift was a more gradual process. New research...

AKRON, Ohio, Dec. 12 /PRNewswire/ -- An Ohio-based company has successfully grown the first Low Radiocarb(TM) food, in this case soybeans, with significantly lower levels of harmful radioactive carbon-14 than normally found in food. Infants and children nourished with safer, low radiocarbon LifeBlocks(TM) foods will suffer tens of billions fewer genetic damage events over their lifetime. By reducing genetic damage, risks of cancer and birth defects may also be reduced. Since genetic...

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...

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...

Researchers can now determine when a human was born by looking into the eyes of the dead.Using the radiocarbon dating method and special proteins in the lens of the eye, researchers at the University of Copenhagen and University of Aarhus can now establish, with relatively high precision, when a person was born. This provides a useful tool for forensic scientists who can use it to establish the date of birth of an unidentified body and could also have further consequences for health science...

By Mark John BRUSSELS (Reuters) - Iranian agents have tried to obtain from South Korea a substance that can be used to boost nuclear explosions in atomic weapons, an Iranian exile group said on Thursday. The National Council of Resistance of Iran (NCRI), which has in the past provided accurate information on hidden Iranian nuclear activities, said Tehran had used front companies to obtain the substance, a hydrogen isotope known as tritium. "The regime has tried to smuggle it in from...
