New smart anti-microbial approach to preventing tooth decay

Preventing cavities could one day involve the dental equivalent of a military surgical strike. A team of researchers supported by the National Institute of Dental and Craniofacial Research report they have created a new smart anti-microbial treatment that can be chemically programmed in the laboratory to seek out and kill a specific cavity-causing species of bacteria, leaving the good bacteria untouched.

Race is associated with unfavorable breast cancer tumor biology

African-American women with breast cancer were more likely to have larger, later-stage tumors that were more difficult to treat and also had lower survival rates than Hispanic and Caucasian women who received the same treatment in two independent series of clinical trials examined by researchers from The University of Texas M. D. Anderson Cancer Center.

Functionalization of individual ultra-short single-walled carbon nanotubes

While most research aimed at developing carbon nanotubes as tumor-targeting drug and imaging agent delivery vehicles has focused on full-length nanotubes, Lon Wilson, Ph.D., and his colleagues at Rice University have been working with ultra-short nanotubes that cells appear to take up more efficiently than their longer counterparts.

Scientists discover how brain turns on system designed to protect nerve cells from toxic "free radicals"

Scientists at Dana-Farber Cancer Institute report they have found how the brain turns on a system designed to protect its nerve cells from toxic "free radicals," a waste product of cell metabolism that has been implicated in some degenerative brain diseases, heart attacks, strokes, cancer, and aging.

An enzyme that regulates ether lipid signaling pathways in cancer annotated by multidimensional profiling

Using a combination of enzyme activity and metabolite profiling, we determined that this protein-whose function was previously unknown-serves as a key regulator of a lipid signaling network that contributes to cancer," said Benjamin F. Cravatt, a Scripps Research professor and a member of its Skaggs Institute for Chemical Biology who led the study.
