Do sustainability measures constrain urban design creativity?

Planners, architects, urban designers and other built environment professionals engage with a myriad of checkboxes, guidelines, requirements and specifications, all of which potentially compromise creativity and innovation in urban design. Approaches that measure performance are accused of belying the nature of places as messy, plural, organic, accidental and emotive; trying to find a formula that works may tick boxes, but it risks creating soulless spaces, oppressing innovation and incorporation of inappropriate design elements. This paper argues that sustainability assessment methods do have something to contribute to creativity and innovation in urban design precisely because they encourage engagement with challenging and often complex societal priorities. Through interviews with built environment professionals and a critical examination of sustainability assessment methods, the authors suggest that such methods can promote creativity and innovation if they engage competently with sustainability, work at a scale that allows for both breadth and depth (typically greater than the building scale) and incorporate in their design a set of eight key characteristics designed to promote creativity and innovation. </jats:p

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
