    Natural or Synthetic? Test reveals origin of chemicals in blubber

    Natural compounds akin to synthetic flame retardants wend their way up marine food chains and accumulate in whale blubber, researchers have found. It's the first time that scientists have used a new radiocarbon-dating method to determine whether potentially troublesome chemicals in the environment are of natural or synthetic origin.

    The oceans contain thousands of naturally occurring...

    Savvy Sieve: Carbon nanotubes filter petroleum, polluted water

    Bridging the gap between the nanoworld and the macroworld, researchers have created a membrane out of carbon nanotubes and demonstrated its potential for filtering petroleum and treating contaminated drinking water.

    Scientists have long valued carbon nanotubes for their high strength and thermal properties (SN: 6/5/04, p. 363: Available to subscribers at http://sciencenews....
