RiboEvo participates in Spelman College YELL summer camp
On July 9th, two summer research experience students traveled with Brande Jones, a postdoctoral research fellow, to participate in an education and public outreach event at Spelman College. Spelman College is a historically black college for women located in Atlanta, GA. Rising high school seniors, Lena Adams and Nya Dawson are currently exploring summer projects within the research labs of the RiboEvo Center. Brande, Lena and Nya presented to the Youth Engaged in Learning and Leading (YELL!) Academy students. Yell! Academy has sixty students in 4th through 9th grades. The students were introduced to astrobiology, rotifer extremophiles and evolution of the ribosome. Lena and Nya guided the students in an activity that investigated the separation of RNA using gel electrophoresis.
George Fox elected 2014 ISSOL fellow
Congrats to George on this prestigious honor.
REU student presents posters
REU student, Helena Ochoa, spent the summer doing research in the Glass lab.
The ribosome is unique in its combination of importance, size, complexity in structure and function, and enormity in available information. The ribosome is the most information-dense volume of space in the known universe. We have developed a web portal, RiboVision, for management and representation of ribosomal data. RiboVision works in rough analogy with Google Maps and is capable of seamlessly switching the type of data displayed and the resolution and magnification of the display. RiboVision allows rapid mapping, filtering, retrieval, analysis and display of wide variety data types, simultaneously on three levels: primary, secondary, and three-dimensional structure.

RiboEvo published PLOS paper
Ribosomes exist in every cell and are responsible for translation of information from mRNA to protein. The structure of the ribosomal core is conserved in all living things, while the outer regions are highly variable. Accurate secondary structures are important for understanding ribosomes. Using 3D structures of ribosomes as input, we have corrected traditional secondary structures of rRNAs. We have generated secondary structures for both large subunit (LSU) 23S/28S and small subunit (SSU) 16S/18S rRNAs of Escherichia coli, Thermus thermophilus, Haloarcula marismortui (LSU rRNA only), Saccharomyces cerevisiae, Drosophila melanogaster, and Homo sapiens. Both LSU and SSU secondary maps are available (http://apollo.chemistry.gatech.edu/RibosomeGallery).

RiboEvo members attend AbGradCon 2012
Three members of the Center for Ribosomal Origins and Evolution (RiboEvo) were invited to speak at AbGradCon 2012 at CalTech in Pasadena, CA from August 27th-30th. AbGradCon is an astrobiology conference exclusively for early career scientists. Three undergraduate RiboEvo members also remotely presented posters, with one winning an award in the poster competition. The conference also featured a site visit to the NASA Jet Propulsion Laboratory and a career panel with established NASA scientists. Two RiboEvo members also attended the associated AbGradCon Research Focus Group on Catalina Island, a whirlwind proposal-writing workshop which took place August 24th-26th.
