Mathematicians Calculate How Randomness Creeps In
You've probably played a 15 puzzle. It's that frustrating yet addictive game with 15 tiles and a single empty space in a 4-by-4 grid.

Here, the authors perform independent screens and identify NuRD as a co-repressor of ZEB1, and demonstrate TBC1D2b as a downstream target of ZEB1/NuRD complex regulating NSCLC metastasis.

Community-level respiration of prokaryotic microbes may rise with global warming
Nature Communications, Published online: 12 November 2019; doi:10.1038/s41467-019-13109-1 Warmer temperatures could increase the growth and metabolic rates of microbes. Here, the authors assemble a dataset of thermal performance curves for over 400 bacteria and archaea, showing that metabolic rates are likely to increase under warming, with implications for global carbon cycling.
