Description:: Temperature affects all biological processes, from the rate of cellular growth and metabolism to the stability of proteins that make up the machinery of life itself. Thus, all organisms must have the capacity to detect and respond to external temperature. Thermosensation endows animals with the ability to sense and respond...

Description:: Processing of sensory information in the brain is a pervasive and fundamental phenomenon across animal species and is involved in both "hard-wired" innate responses as well as learned and adaptive behaviors. Here, I show that the avoidance of hot temperature, a simple innate behavior, contains unexpected plasticity and complex processing...

Description:: Proper spatiotemporal expression of genes is essential during development. One method of regulation of signaling-responsive genes is at the level of transcription. In this work, I present the adaptation of single molecule fluorescent in situ hybridization for use in Drosophila imaginal disc tissues in order to more precisely quantify transcript...

Description:: In eukaryotic organisms, genomic DNA is organized and condensed into repeating arrays of nucleosomes. The histone protein octamer of each nucleosome wraps 147 base pairs of DNA, effectively restricting access by transcription factors and other regulatory proteins to that region. An additional histone, histone H1, binds the DNA outside the...
