We lost a great scientific mind on February 20, 2020 with the passing of Alan Poland. Alan’s work represents one of the most significant achievements in modern toxicology, the discovery of the Ah receptor and its role in the toxic mechanism of halogenated dioxins and dibenzofurans. His pioneering work, employing these highly toxic molecules as molecular probes of biological function, opened the door

Elijah Petersen, Ph.D. is the recipient of the 2020 Chemical Research in Toxicology Young Investigator Award. As a Research Scientist at the National Institute of Standards and Technology (NIST), Dr. Petersen has spearheaded efforts to develop robust, reproducible standard methods for assessing the effect of nanomaterial contaminants on living organisms. Another focus of his research at NIST involves

In the original article, the description of the incorporation frequency opposite l-T was not completely correct and should be corrected as follows: In the abstract, “nucleotide incorporation opposite the l-T site was” (p. 2276, line 14) should be corrected to “transition from l-T to”. Similarly, “that nucleotide incorporated opposite the l-T site was” in the third section of the Results (p. 2282, line

“A coin has two sides” Professor Cynthia J. Burrows “A coin has two sides” As a keynote speaker of this year’s ACS TOXI meeting, Cynthia J. Burrows emphasized the idea that DNA damage can have both positive and negative impacts on human health. This novel idea is the main driving force of her research. Since her undergraduate studies in physical organic chemistry with Prof. Stan Cristol, chemistry

For Professor Pete Dedon, this year’s ACS Division of Chemical Toxicology (TOXI) Founder’s Award winner, the joy associated with his research on nucleic acids is his driving force. He says “When it’s not fun anymore, I quit doing it”. Since his undergraduate studies at the University of Rochester, where he addressed platinum-DNA crosslinks, he has never left the vast and exciting field of nucleic acid

The compound name for o-toluidine dimer (head-to-tail binding) was misprinted. The correct name is “2-methyl-N4-(2-methylphenyl)benzene-1,4-diamine (MMBD)”. This error appeared in three places: the Abstract, Experimental Procedures, and Results sections. This article has not yet been cited by other publications.
