A new form of energy-transfer, reported today in Nature (3 July 2008) may have implications for the study of reactions going on in the atmosphere, and even for those occurring in the body. Imagine a simple molecule consisting of two atoms as being like two balls attached together by a spring. If an incoming atom strikes one side of the molecule, the spring compresses and you would expect the molecule to jump backwards "“ remember Newton's cradle?...

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...

WASHINGTON -- A heavy form of hydrogen created just moments after the Big Bang has been found in larger quantities than expected in the Milky Way, a finding that could radically alter theories about star and galaxy formation, researchers said on Monday. This form of hydrogen, called deuterium, has apparently been hiding out in interstellar dust grains, changing from an easily detectable gaseous form to a harder-to-see solid form, the French and U.S. team of astrophysicists said. Writing in...

Call it CSI Milkyway. Scientists using NASA's Far Ultraviolet Spectroscopic Explorer (FUSE) have solved a 35-year-old mystery about the whereabouts of deuterium, an isotope of hydrogen often called "heavy hydrogen." The answer "is as unsettling as it is exciting," says the science team leader because this finding could radically alter theories about star and galaxy formation. Deuterium, which contains one proton and one neutron, was created a few minutes after the Big Bang. Its presence today...

If you want to hear a little bit of the Big Bang, you're going to have to turn down your stereo. That's what neighbors of MIT's Haystack Observatory found out. They were asked to make a little accommodation for science, and now the results are in: Scientists at Haystack have made the first radio detection of deuterium, an atom that is key to understanding the beginning of the universe. The findings are being reported in an article in the Sept. 1 issue of Astrophysical Journal Letters. The...

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...

LONDON -- If scientists succeed in building an experimental nuclear fusion reactor and making it work it could solve the world's energy problems for the next 1,000 years or more, a leading scientist said on Tuesday. After months of wrangling, France defeated a bid from Japan and signed a deal to build the 10-billion-euro ($12 billion) experimental reactor at Cadarache in the south of the country. Ian Fells, of the Royal Academy of Engineering in Britain and an expert on energy conversion,...

ALBUQUERQUE, N.M. - Sandia National Labs has accelerated a small plate from zero to 76,000 mph in less than a second. The speed of the thrust was a new record for Sandia's Z Machine - sometimes referred to as the fastest gun in the West. Actually the fastest in the world, it is now able to propel small plates at 34 kilometers a second, faster than the 30 km/sec that Earth travels through space in its orbit about the sun, 50 times faster than a rifle bullet, and three times the velocity...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
