fires. The hydrates extinguished flames faster than the other two substances, they say. The hydrates also used less water than ordinary ice and released less carbon dioxide than dry ice, they note. Grinding the pellets into smaller pieces boosted their flame-fighting efficiency, the researchers say. - MTS

New biosensor for most serious form of Listeria food poisoning bacteria
Analytical Chemistry

Scientists in Indiana are reporting development of a new biosensor for use in a faster, more sensitive test for detecting the deadliest strain of Listeria food poisoning bacteria. That microbe causes hundreds of deaths and thousands of hospitalizations each year in the United States, particularly among people with weakened immune systems. Their study appears in the current issue of ACS' Analytical Chemistry, a semi-monthly journal.

Arun Bhunia and colleagues note in the new study that fast, highly effective tests already are available for five of the six known species of Listeria. These tests use antibodies that signal the presence of the bacteria. However, no rapid, sensitive tests are available for detecting Listeria monocytogenes, the deadliest of the species, the researchers say.

The scientists describe development of the biosensor using so-called heat shock proteins which the body produces in response to stress instead of
