Machine learning solves RNA puzzlesRNA molecules fold into complex three-dimensional shapes that are difficult to determine experimentally or predict computationally. Understanding these structures may aid in the discovery of drugs for…

SARS-CoV-2 from alpha to epsilonAs battles to contain the COVID-19 pandemic continue, attention is focused on emerging variants of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus that have been deemed variants of…

Locking structure to high temperatureBecause of atomic diffusion, metal alloys with nanometer-sized crystal grains do not retain their structure at high temperature. Xu et al. found that a minimum-interface structure allows a supersaturated…

How to catch a dynamic stateAMP-activated protein kinase (AMPK) is a key sensor of energy status in eukaryotes. Its dynamic structure is regulated by allosteric factors including phosphorylation and binding of nucleotides and metabolites.…

Single seismometer structureBecause of the lack of direct seismic observations, the interior structure of Mars has been a mystery. Khan et al., Knapmeyer-Endrun et al., and Stähler et al. used recently detected marsquakes from the…

Mother knows bestInheritance of social status, and its associated costs and benefits, is well demonstrated in humans. Whether such an intergenerational system occurs in other species is harder to demonstrate. Ilany et al. looked at nearly…

SummaryProteins are the minions of life, working alone or together to build, manage, fuel, protect, and eventually destroy cells. Last year, in a result hailed as a turning point, computational biologists showed that artificial intelligence…

Shape and nanocrystal transformationsCation exchange reactions that change the composition of a nanocrystal (NC) under mild conditions usually preserve the sublattice of the larger anions. Li et al. found that the shape of roxbyite (Cu1.8S)…

How to feed an enzyme ethaneWhen released from ocean floor seeps, small hydrocarbons are rapidly consumed by micro-organisms. Methane is highly abundant and is both produced and consumed by microbes through well understood biochemical…
