This project was initiated in response to two regulatory developments: (1) an International Agency for Research on Cancer (IARC) ruling to upgrade quartz from a Group 2A to a Group 1 human carcinogen (IARC 1997) and (2) an EPA requirement that communities monitor PM10 (EPA 1986) and a possible modification of EPA guidelines to include PM2.5 (EPA 1996). To determine whether inhalation of large a...

Transposable elements (TEs) are repetitive DNA sequences that can make new copies of themselves that are inserted elsewhere in a host genome. The abundance and distributions of TEs vary considerably among phylogenetically diverse hosts. With the aim of exploring thebasis of this variation,we evaluatedcorrelations between several genomic variables and the presence of TEsand non-TE repeats in the...

he fuel-efficient diesel engine may face a bleak future unless engineers can dramatically reduce its particulate emissions to meet likely future regulations. Low-cost solutions may emerge if engineers can rethink engine and fuels technologies in tandem, tailoring the fuel properties to the engine design and vice versa. To help them achieve that match, Energy Laboratory researchers are formulati...

In situ volatile collection, analysis, and comparison of three Centaurea species and their relationship to biocontrol with herbivorous insects.

Centaurea solstitialis, commonly known as yellow starthistle, is an invasive plant listed as a noxious weed in the western areas of North America and is the target of classical biological control, which involves release of herbivores known to be specific to this plant. These insects often choose their host plant on the basis of the volatile organic compounds (VOCs) emitted. Accordingly, volatil...
