Understanding of bacterial protein degradation is illuminated by cryo-EM structures of the substrate-bound ClpXP complex from Neisseria meningitidis at 2.3 to 3.3 Å resolution.
At Cuatro Ciénegas, the ancestral niche conditions of the ancient shores of Laurentia persisted along with its microbial communities that have been coevolving for a very long time.
The reconstitution of a functional envelope protein from an extinct hominid retrovirus reveals its receptor and an ancient host defense that may have led to the extinction of the virus.
Swine populations worldwide are sporadically infected by influenza viruses from humans and birds leading to geographically heterogeneous swine influenza virus populations that pose epizootic and pandemic threats.
Autonomous patterns of cell contraction in the context of localized apical extracellular matrix constraints specify tissue stresses that reshape the wing epithelium.
The transition to the aggregative stage of Capsaspora owczarzaki, a close unicellular relative to Metazoa, is associated with significant upregulation of orthologs of genes that are important for multicellularity in metazoans.
Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.
A mimetic complex composed of at least 140 species of ants, wasps, spiders, true bugs and treehoppers, all with conspicuous golden bodies, has been discovered.
