knock-offs are almost physically and chemically indistinguishable from the real thing. Scientists need a better way to identify adulterated honey, the researchers say.

Herbreteau and colleagues describe a new, highly sensitive test that uses a special type of chromatography to separate and identify complex sugars (polysaccharides) on their characteristic chemical fingerprints. To test their method, the scientists obtained three different varieties of pure honey from a single beekeeper and then prepared adulterated samples of the honeys by adding 1 percent corn syrup. They showed that the new technique accurately distinguished the impure honeys from the pure versions based on differences in their sugar content. MTS

ARTICLE #4 FOR IMMEDIATE RELEASE

New "smart" polymer reduces radioactive waste at nuclear power plants
Industrial & Engineering Chemistry Research

Scientists in Germany and India are reporting development of a new polymer that reduces the amount of radioactive waste produced during routine operation of nuclear reactors. Their study, which details a first-of-its-kind discovery, has been published in the ACS' Industrial & Engineering Chemistry Research, a bi-weekly journal.

Brje Sellergren and colleagues note that structural materials such as carbon steel in power plants' water cooling systems form deposits of metal oxides when they interact w
