Specific scents trigger moth behavior: a report from the Hildebrand Lab
In a new paper, "Characterizing and Coding of Behaviorally Significant Odor Mixtures," published in the February 24th issue of the journal Current Biology. Jeffery Riffell, Hong Lei, Thomas Christensen and John Hildebrand, describe how a moth recongizes the particular mix of odors that signals a food source. Jeff describes their work in the article, "How Moths Key into the Scent of Flowers" (byline: Mari Jensen). |

Undergraduate Emily Ricq Receives Howard Hughes Award
Emily Ricq, an undergraduate researcher in the Tolbert lab, is the recipient of 2009 Howard Hughes Medical Institute Science for Life Undergraduate Creativity Award. The award is the result of work Emily did to develop a method for synthesizing cell-penetrating peptides in solution at the Université Pierre et Maire Curie in Paris while studying abroad last year. Emily has been a member of the Tolbert lab since 2005 and is working on a joint project with Lynne Oland (ARLDN) and Robin Polt (Chemistry).
Emily is currently examining the role of dienyl ceramide, which is an unusual but naturally occurring lipid product isolated from the caterpillar of the moth Manduca sexta. Her work is carried out in a cell line derived from embryonic M. sexta, and thus far suggests that dienyl ceramide specifically influences cell shape and cell division. It also suggests the presence of a previously unknown pathway in glycosphingolipid metabolism.

Arizona Daily Star interviews Dr. Linda Restifo about her genetics research
Dr. Linda Restifo describes her current work in genetics an interview published by the Arizona Daily Star on 12/29/08 in the article, Tiny insects have big role in UA research: Professor studies fruit fly brains for genetic insights. In the interview, Dr. Restifo discusses the methods she uses to screen drugs which have the potential to act on mutated brain cells. The goal of this research is to identify drugs that could increase brain function in people suffering from metal disorders such as autism or mental retardation. Dr. Restifo was recently awarded funding by the Autism Speaks Foundation for a pilot study entitled, "Novel cell-based assay for autism-research and drug discovery."
