In an advance toward the first portable device for detecting human bodies buried in disasters and at crime scenes, two Penn State forensic scientists report early results from a project to establish the chemical fingerprint of death. According to Dan Sykes, senior lecturer and director of analytical instructional laboratories at Penn State and the project's leader, "Acertaining a profile of the chemicals released from decomposing bodies could lead to a valuable new addition to the forensic toolkit: an electronic device that could determine the time elapsed since death quickly, accurately, and onsite." The team is presenting its research in a poster at the 238th National Meeting of the American Chemical Society at 7:00 p.m. on 16 August 2009.

Cleaning oily smears from kitchen countertops, mirrors, garage floors, and other surfaces with plain water â€" rather than strong detergents or smelly solvents â€" may seem like pure fantasy. But scientists in Indiana today describe what they believe to be a simple and effective state-of-the-art oil stain remover. They have developed a new coating for glass, plastics, and a range of other materials that would enable consumers to wipe away those pesky oils with plain water.

The Atlantic Ocean's second Tropical Depression has been on shaky ground since it formed early in the week of August 11. It meandered westward from the African coast and maintained its tropical depression status until weakening to a remnant low. Now it has the potential to come back. In addition to Tropical Depression 2, there are three other areas forecasters are watching in the Atlantic Basin. Residents of Florida should particularly be watchful as there's a potential for tropical development on both the east and west coasts this weekend.

These earlier conclusions, however, were based on observations of patients with poorly controlled asthma who had not received care based on current guidelines.

COLD SPRING HARBOR, N.Y. (Wed., Aug. 5, 2009) â€" Vectors derived from retroviruses are useful tools for long-term gene transfer because they allow stable integration of transgenes and propagation into daughter cells. Lentiviral vectors are preferred because they can transduce non-proliferating cellular targets. These vectors can be engineered to target specific tissues. In the August issue of Cold Spring Harbor Protocols (www.cshprotocols.org/TOCs/toc8_09.dtl), François-Loïc Cosset and colleagues from Ecole Normale Supérieure de Lyon (http://hvd.ens-lyon.fr/human_virology_dpt) present a method for targeting hematopoietic stem cells using engineered viral vectors. The article, "Hematopoietic Stem Cell Targeting with Surface-Engineered Lentiviral Vectors," is freely available on the website for Cold Spring Harbor Protocols (http://cshprotocols.cshlp.org/cgi/content/full/2009/8/pdb.prot5276).
