Characterization and structure of the manganese-responsive transcriptional regulator ScaR.

Nov 2009 The streptococcal coaggregation regulator (ScaR) of Streptococcus gordonii is a manganese-dependent transcriptional regulator. When intracellular manganese concentrations become elevated, ScaR represses transcription of the scaCBA operon, which ... Read more...

Sequestering uranium and technetium through co-precipitation with aluminum in a contaminated acidic environment.

29 Sep 2009 This research evaluated a method of controlled base addition for immobilizing uranium (U) and technetium (Tc) through coprecipitation with aluminum (Al) and other metal ions which coexist in a highly contaminated acidic environment. The batch and ... Read more...

Magnetic wire traps and programmable manipulation of biological cells.

15 Sep 2009 We present a multiplex method, based on microscopic programmable magnetic traps in zigzag wires patterned on a platform, to simultaneously apply directed forces on multiple fluid-borne cells or biologically inert magnetic microparticles or ... Read more...
