Antibiotic resistance is increasingly widespread, largely due to human influence. Here, we explore the relationship between antibiotic resistance genes and the antimicrobial chemicals triclosan, triclocarban, and methyl-, ethyl-, propyl-, and butylparaben in the dust microbiome. Dust samples from a mixed-use athletic and educational facility were subjected to microbial and chemical analyses usi...
Evolution of insecticide resistance, measured by the though the rate at which this occurred varied. The slowfrequency of a resistant allele and by population size, was est response to selection occurred when (I) the populasimulated on a computer. The effects of dominance, tion was diluted by immigrants, (2) population density initial gene frequency, refugia, immigration, and reprowas drasticall...
Resistance to sweetpotato weevils (Cylas spp.) has been identified in several sweetpotato (Ipomoea batatas) landraces from East Africa and shown to be conferred by hydroxycinnamic acids that occur on the surface of storage roots. The segregation of resistance in this crop is unknown and could be monitored using these chemical traits as markers for resistance in F1 offspring from breeding progra...
www.sciencemag.org SCIENCE VOL 333 5 AUGUST 2011 663 COVER A pair of chemical compounds (light blue and purple) target wild-type and mutant forms of the Plasmodium falciparum chloroquine resistance transporter, which mediates the parasite’s (yellow) resistance to the widely used antimalarial drug. Using high-throughput chemical and genetic analyses, Yuan et al. identify potential new antimalari...

Polymer concrete (PC) is a composite material prepared by resin and aggregates. Advantages of polymer concretes include rapid curing at ambient temperatures, high flexural and compressive strengths, excellent chemical resistance and low permeability. In this research, a comparative study was performed on degradation of polyester resin concrete in different chemical solutions. Polymer concrete s...
