Lab disinfectant harms mouse fertility p964
Two chemicals widely used in cleaning agents for homes, offices and hospitals cause birth defects and fertility problems in mice whose cages have been in contact with them, according to Patricia Hunt at Washington State University in Pullman. The quaternary ammonium compounds ADBAC (n-alkyl dimethyl benzyl ammonium chloride) and DDAC (didecyl dimethyl ammonium chloride) were identified after an exhaustive search for what was causing a massive drop-off in mouse fertility after Hunt moved her research animals to Pullman from Case Western Reserve Medical School in Cleveland, Ohio, in 2005. The chemicals were in the disinfectant Virex used in the facility. It is Hunt's second accidental foray into toxicology. In 2003 she linked a rash of mysterious egg defects in her research animals to bisphenol A, a chemical that began leaching from plastic water bottles after a high-pH floor detergent was mistakenly used to clean them. Hunt, who studies mammalian egg development, announced her latest results at the Society for the Study of Reproduction meeting in Kona, Hawaii, last month.

Commentary
Repairing research integrity p980
A survey suggests that many research misconduct incidents in the United States go unreported to the Office of Research Integrity. Sandra L. Titus, James A. Wells and Lawrence J. Rhoades say it's time to change that.
