The identification of over-represented transcription factor binding sites from sets of co-expressed genes provides insights into the mechanisms of regulation for diverse biological contexts. oPOSSUM, an internet-based system for such studies of regulation, has been improved and expanded in this new release. New features include a worm-specific version for investigating binding sites conserved b...

Some commentators have emphasised the 'structural' difference between construction and other industrial sectors (construction is low tech., one-off, other manufacturing industries can amortize R+D costs over long production runs, etc). Others have considered the organisational aspect of the industry, focussing on issues of discipline specialisation, organisational fragmentation and adversarial ...
