Light may play a much more important role in bacterial life than has previously thought

The bacteria that cause brucellosis can sense light and use the information to regulate their virulence, according to a study in the August 24 issue of the journal Science.

Cell-based sensor for analysis of EGFR biomarker expression in oral cancer

Using a microfluidic device designed to capture and enrich cells from biological samples, a research team at The University of Texas at Austin has developed a test that can detect an important early marker for oral squamous cell carcinoma, which accounts for more than 90 percent of oral cancers. Oral cancer is the sixth most common cancer worldwide and is difficult to detect early enough to treat successfully.
