Mrna, Rrna And Dna Quantitative Stable Isotope Probing With H218o Indicates Use Of Old Rrna Among Soil Thaumarchaeota, Katrina Papp, Bruce A. Hungate, Egbert Schwartz

Civil and Environmental Engineering and Construction Faculty Research

RNA is considered to be a short-lived molecule, indicative of cellular metabolic activity, whereas DNA is thoughtto turn over more slowly because living cells do not always grow and divide. To explore differences in the ratesof synthesis of these nucleic acids, we used H218O quantitative stable isotope probing (qSIP) to measure theincorporation of18O into 16S rRNA, the 16S rDNA,amoAmRNA and theamoAgene of soil Thaumarchaeota.Incorporation of18O into the thaumarchaealamoAmRNA pool was faster than into the 16S rRNA pool,suggesting that Thaumarchaea were metabolically active while using rRNA molecules that were likely synthe-tized prior to H218O addition. Assimilation rates of18O into 16S rDNA …

Magnetic Field-Driven Convection For Directed Surface Patterning Of Colloids, Jin Gyun Lee, Vanel Porter, William A. Shelton, Bhuvnesh Bharti

Faculty Publications

Drying sessile droplets is a promising route to transform colloidal dispersions into surface coatings, which are widely used in material design and biochemical detection. However, directing the assembly of the particles within drying droplets and achieving surface patterns beyond the well-known coffee-ring formation remain a challenge. Here, we present a new principle of directing the assembly of nonmagnetic colloidal particles dispersed in a magnetic fluid and generating unusual surface patterns. We use the ability of ferrofluids to change phases with the application of magnetic fields to program the assembly of nonmagnetic microparticles present in drying sessile droplets. We show that …
