Research on teamwork has shown that teams are more productive and produce better results than individuals working on their own. Yet, research on individuals' work preferences makes it clear that not everyone prefers working in teams. In order to improve teamwork and achieve better results in both the collegiate arena and in the professional world, this study was designed to research different factors that affect a group's performance and creativity: satisfaction, familiarity, and the behavioral styles of individual team members. Additionally, this study addresses if the group's composition of Keirsey types \u2014 temperament patterns \u2014 also play a role in the group's creativity and performance. In this study, students created teams of four to seven students and completed specific in-class activities called Applied Insights. Groups composed mostly of Guardians, one of the four Keirsey temperaments, are able to adapt to the task at hand, which is demonstrated here with creativity. Further, groups who perceive themselves as sharing similar traits with many members are more satisfied and achieve a higher overall performance. Lastly, groups comprised of individuals who were least familiar with their teammates they had not previously worked with, produced more creative results in the short run. Whereas groups comprised of individuals who were least familiar with their teammates they had previously worked with, produced better overall results in short run.

The filamentous, non-heterocystous cyanobacterium Lyngbya aestuarii is an important contributor to marine intertidal microbial mats system worldwide. The recent isolate L. aestuarii BL J, is an unusually powerful hydrogen producer. Here we report a morphological, ultrastructural, and genomic characterization of this strain to set the basis for future systems studies and applications of this organism. The filaments contain circa 17 μm wide trichomes, composed of stacked disk-like short cells (2 μm long), encased in a prominent, laminated exopolysaccharide sheath. Cellular division occurs by transversal centripetal growth of cross-walls, where several rounds of division proceed simultaneously. Filament division occurs by cell self-immolation of one or groups of cells (necridial cells) at the breakage point. Short, sheath-less, motile filaments (hormogonia) are also formed. Morphologically and phylogenetically L. aestuarii belongs to a clade of important cyanobacteria that include members of the marine Trichodesmiun and Hydrocoleum genera, as well as terrestrial Microcoleus vaginatus strains, and alkalyphilic strains of Arthrospira. A draft genome of strain BL J was compared to those of other cyanobacteria in order to ascertain some of its ecological constraints and biotechnological potential.

The genome had an average GC content of 41.1%. Of the 6.87 Mb sequenced, 6.44 Mb was present as large contigs (>10,000 bp). It contained 6515 putative protein-encoding genes, of which, 43% encode proteins of known functional role, 26% corresponded to proteins with domain or family assignments, 19.6% encode conserved hypothetical proteins, and 11.3% encode apparently unique hypothetical proteins. The strain's genome reveals its adaptations to a life of exposure to intense solar radiation and desiccation. It likely employs the storage compounds, glycogen, and cyanophycin but no polyhydroxyalkanoates, and can produce the osmolytes, trehalose, and glycine betaine. According to its genome, BL J strain also has the potential to produce a plethora of products of biotechnological interest such as Curacin A, Barbamide, Hemolysin-type calcium-binding toxin, the suncreens scytonemin, and mycosporines, as well as heptadecane and pentadecane alkanes. With respect to hydrogen production, initial comparisons of the genetic architecture and sequence of relevant genes and loci, and a comparative model of protein structure of the NiFe bidirectional hydrogenase, did not reveal conspicuous differences that could explain its unusual hydrogen producing capacity.
