Blue Exploration

Lateralization of ventral fins use during object exploration in the blue gourami (Trichogaster trichopterus).

Blue gourami fish have a pair of modified ventral fins that are used to obtain tactile information about surrounding objects. Use of ventral fins by blue gourami was investigated during initial exploration of novel objects. When exposed to a sequence of novel plastic objects, varying in shape and colour, the blue gourami showed preferential use of the left fin during initial contacts. Lateralit...

Exploration of Parallel Storage Architectures for a Blue Gene/L on the TeraGrid

This paper examines the construction of a cost-effective storage cluster for an IBM Blue Gene/L supercomputer on the TeraGrid. The performance of storage clusters constructed using commodity Opteron servers and directly-attached fibre-channel RAID systems is analyzed utilizing the GPFS, Lustre, and PVFS file systems. In addition to traditional client scalability results, server scalability is a...

Exploration of new chromophore structures leads to the identification of improved blue fluorescent proteins.

The variant of Aequorea green fluorescent protein (GFP) known as blue fluorescent protein (BFP) was originally engineered by substituting histidine for tyrosine in the chromophore precursor sequence. Herein we report improved versions of BFP along with a variety of engineered fluorescent protein variants with novel and distinct chromophore structures that all share the property of a blue fluore...

Consider two adolescents: Person One and Person Two. Person One has never used substances and exhibits relatively few behavioral (conduct) problems. On the other hand, Person Two uses substances frequently and more commonly exhibits poor conduct. If you were to guess, which of the individuals would you expect to have lower overall judgment and self-regulation? If you answered Person Two, your i...
