RNA sequence-structure-function relationships can be studied via assays of variant activity. The authors developed a method to systematically determine ribozyme variant kinetics, using it to map double-mutant interactions and show that cleavage rate

Contacts between RNA polymerase and promoter DNA modulate the strength of binding and the frequency of promoter escape during transcription. Here, the authors describe a single molecule optical-trapping assay to study transcription initiation and obs

This paper advances previous literature that has posited a climate-nutrition link without identifying a specific pathway via agriculture. We measure the specific effects of exposure to extreme heat on maize yields in Tanzania, and then test whether p

The thiamine pyrophosphate (TPP) riboswitch is a cis-regulatory element in mRNA that modifies gene expression in response to TPP concentration. Its specificity is dependent upon conformational changes that take place within its aptamer domain. Here,

Kinesin-1 is a dimeric motor that transports cargo along microtubules, taking 8.2-nm steps in a hand-over-hand fashion. The ATP hydrolysis cycles of its two heads are maintained out of phase by a series of gating mechanisms, which lead to processive

Graphical abstract
Highlights • Policies and programs often aim to bring nutritious diets within reach of the poor. • We use food prices and composition to compare least-cost diets around the world. • Globally, nutrient adequacy costs 2.66

Massively parallel, quantitative measurements of biomolecular activity across sequence space can greatly expand our understanding of RNA sequence-function relationships. We report the development of an RNA-array assay to perform such measurements and

Significance Riboswitches are structured mRNA elements that regulate gene expression in response to metabolite ligands. The bacterial glmS riboswitch regulates a protein with a key role in cell wall biosynthesis. This riboswitch follows an unusual me
