Natural variation in hecw-1 encoding an E3 ubiquitin ligase influences the avoidance of pathogenic bacteria by Caenorhabditis elegans and forms a molecular basis for behavioural variation.
NMR spectroscopy is used to elucidate the intermediates in the bacterial transformation of alkylphosphonates to phosphate, showing that the essential bond cleavage occurs in a radical-based reaction in the presence of S-adenosyl-l-methionine.
Sequencing of Medicago truncatula, a model organism of legume biology, shows that genome duplications had a role in the evolution of endosymbiotic nitrogen fixation.
Amphibian populations are declining; here, the spatial distribution and interactions of threats from climate change, land-use change and the spread of fungal disease are assessed.
Optogenetic stimulation in the zebrafish olfactory bulb and downstream read out of activity in the homologue of olfactory cortex demonstrate how temporal filtering can extract specific components of neuronal codes.
