    Water security affects human wellbeing both directly and indirectly, through its effects on biodiversity. Here, a global map has been generated that shows threats to both direct and indirect water security from a full range of potential stressors. Technological investments have also been incorporated. The map shows that nearly 80% of the world's population is exposed to high levels of threat to water security. Investment enables rich nations to offset high stressor levels, but less wealthy nations remain vulnerable.

    Taxonomists should work with specialists in pattern recognition, machine learning and artificial intelligence, say Norman MacLeod, Mark Benfield and Phil Culverhouse — more accuracy and less drudgery will result.

    Predicting the structure of a folded protein from first principles for any given amino-acid sequence remains a formidable computational challenge. To recruit human abilities to the task, these authors turned their Rosetta structure prediction algorithm into an online multiplayer game in which thousands of non-scientists competed and collaborated to produce new algorithms and search strategies for protein structure refinement. This shows that computationally complex problems can be effectively 'crowd-sourced' through interactive multiplayer games.

    The need to maintain the structural and functional integrity of an evolving protein limits the range of acceptable amino-acid substitutions — but to what extent does this constrain how far homologous protein sequences can diverge? Here, sequence divergence data are used to explore the limits of protein evolution, and to conclude that ancient proteins are continuing to diverge from one another, indicating that the protein sequence universe is slowly expanding.

    Modern networks are rarely independent, instead being coupled together with many others. Thus the failure of a small fraction of nodes in one network may lead to the complete fragmentation of a system of several interdependent networks. Here, a framework is developed for understanding the robustness of interacting networks subject to such 'cascading' failures. Surprisingly, a broader degree distribution increases the vulnerability of interdependent networks to random failure.

    Genotype and phenotype cannot be connected simply by one-to-one mapping; instead they are linked by the nonlinear process of development. Here, a computational model is described — based on real data about the development of seal teeth — that attempts to combine the three. The results show that a few genetic parameters regulating signalling during cusp development may explain variation among individuals. But a cellular parameter regulating epithelial growth may explain tooth-to-tooth variation along the jaw.

    Local adaptations are often governed by several interacting genes scattered throughout the genome. Here a novel type of multi–locus genetic variation is described that has been maintained within a species over a vast period of time. A balanced unlinked gene network polymorphism is dissected that involves galactose utilization in a close relative of baker's yeast.

    A defining focus of synthetic biology is the engineering of genetic circuits with predictive functionality in living cells. Here, a decade after the first synthesized genetic toggle switch and oscillator, an engineered gene network with global intercellular coupling is designed that is capable of generating synchronized oscillations in a growing population of cells.
