Small RNAs, including microRNAs (miRNAs), small interfering RNAs
(siRNAs), and trans-acting siRNAs (tasiRNAs), control gene expression
and epigenetic regulation. Although the roles of miRNAs and
siRNAs have been extensively studied, their expression diversity
and evolution in closely related species and interspecific hybrids
are poorly understood. Here, we show comprehensive analyses...
What is the uncertainty of climate-carbon cycle projections in response to anthropogenic greenhouse gas emissions and how can we reduce this uncertainty? We address this question by quantifying the ability of available ocean tracer observations to constrain the values of diapycnal diffusivity in the pelagic ocean (Kv), a key uncertain...
