Methodological optimization makes possible the long-awaited derivation of human embryonic stem cells from embryos obtained with somatic cell nuclear transfer.
Binning based on differential read coverage, rather than sequence composition, allows separation of metagenomic sequence reads into species-level clusters that can be assembled into single chromosomes.
To produce enough raw material for high-quality whole-genome sequencing, researchers capture and grow single, culture-resistant bacteria in gel micro-droplets.
