A new international collaborative study led by George Johnson and featuring contributions by Lya G. Soeteman-Hernández, B. Bhaskar Gollapudi, Kerry L. Dearfield, James T. MacGregor, Lynn H. Pottenger, Chadwick M. Thompson, and Errol Zeiger is the “Editor’s Choice” and on the cover of this month’s edition of Environmental and Molecular Mutagenesis. The study identifies a preferred approach for determining genetic toxicity points of departure, offering quantitative data for use in human health risk assessments and resultant regulatory decision making.

“Louisiana shrimp safe to eat after BP Gulf of Mexico spill, local study says” read a recent headline from The New Orleans Times-Picayune. The referenced study was by Jeff Wickliffe, Mark Wilson, and Bridget Simon, among others, who studied shrimp consumption among Vietnamese-American communities in Southeast Louisiana and compared it to the levels of polycyclic aromatic hydrocarbons in Gulf shrimp after the oil spill. The research found no acute health risks or excess cancer risk associated with consumption of the shrimp.
As reported by Virginia Tech News, Marion F. Ehrich is working with colleagues at Virginia Tech and the University of Minnesota to make a vaccination for nicotine addiction a reality. As envisioned by the researchers, the vaccine would block the pleasure response associated with nicotine consumption with the help of biodegradable nanoparticles.
