Katie Luckett ('16) received a travel award from the Faculty for Undergraduate Education (FUN) to attend the Society for Neuroscience meetings with Jean Hardwick. This international conference is attended by ~30,000 scientists from around the world. Katie presented the research she has been working in Jean's lab over the past two years, which focuses on the role of neuropeptides in neuronal regulation of the heart. Katie also received support the H&S student travel fund and the Biology Department for her attendance at this conference.

Annual Society for Neuroscience meetings in Washington DC. November 2014.
- Biochemistry majors Emily Powers ('15) and Katie Luckett ('16) presented their research, performed in collaboration with Jean Hardwick. The research examined how neurons controlling the heart are altered with chronic heart disease. Emily Powers received a travel award from the Faculty for Undergraduate Neuroscience to support her attendance at the conference. Both students were also supported by the EGI fund and the Bernard Fund from the Biology department. This years Society for Neuroscience meetings included 31,263 attendees from 86 countries, 3,837 posters, and 15,510 presenters.

Rachel Noyes (Biochemistry ’13) & David Burgess. Poster Presentation. "Micromere cell membranes in Lytechinus pictus embryos have distinct properties". 2011 SACNAS National Conference. San Jose, CA. October 2011. She was in an REU (research experience for undergraduates) and the MBL (marine biological laboratories). Her advisor was David Burgess. Also there is an article on the MBL site about my program with a picture of me http://blog.mbl.edu/?p=1432. Rachel also received a H&S EGI Award to help defray the conference costs.
Developing embryos undergo numerous cell divisions following distinct differentiation pathways before maturing into complex organisms. In sea urchins beginning as early as the fourth division specialization occurs in the vegetal cells as an unequal division gives birth to macromeres and micromeres. These micromeres lose adhesion, migrate inside of the blastula, and give rise to the larval skeleton and germ cells. They have been found to vary from other cells of the embryo in more than just size and transcriptome though. Others have noted that these micromeres generally lack microvilli. Since microvillar membranes found on the apical surfaces of epithelial cells contain lipid rafts rich in gangliosides and cholesterol, we questioned whether membranes of micromeres lack such lipids. Using spinning disc confocal microscopy we observed the presence of gangliosides through use of fluorescent cholera toxin B in fixed and in live dissociated blastomeres giving birth to micromeres. In fixed blastomeres, the presence of an even actin rich cortex was observed on all cells by the use of fluorescent phalloidin. In contrast to the even distribution of actin, the cell membranes in micromeres were found to lack cholesterol rich lipid rafts observed on all other cells of the embryo likely due to the loss of apical membrane components caused by the unique division that leads to these cells. The process of cell division, where new membrane is delivered via exocytosis, may result in micromeres lacking “apical” cell surfaces found in the cells of the blastula.
