The beta-globin gene clusters in platypus, mammals and birds are flanked by the same genes, indicating that this arrangement of genes originated before the divergence of birds and mammals.

Novel expressed sequence tags (ESTs) from C. elegans that map to previously unknown genes, splice variants and non-coding RNAs have been uncovered by transcriptome profiling of the nematode's first larval stage using next generation pyrosequencing technology.

The toxic effects of chemical contaminants like copper on a key indicator organism, the earthworm, can be monitored by combining metabolomics and transcriptomics, a systems ecotoxicology approach that provides detailed molecular information about adaptation to soil pollutants.
