    Non-classical amine recognition evolved in a large clade of olfactory receptors

    Qian Li et al.
    Fish trace amine-associated receptors evolved a novel structural motif that enables the detection of chemically diverse amine odors in a non-canonical 'inverted' orientation.

    Drought adaptation in Arabidopsis thaliana by extensive genetic loss-of-function

    J Grey Monroe et al.
    Gene knockouts provide valuable genetic fuel for climate adaptation in nature.

    Transcription factor clusters regulate genes in eukaryotic cells

    Adam JM Wollman et al.
    Transcription factors form clusters independently of the presence of DNA, which regulate target genes as opposed to individual monomers, addressing a longstanding question of how transcription factors can find gene targets so quickly.

    Single cell, super-resolution imaging reveals an acid pH-dependent conformational switch in SsrB regulates SPI-2

    Andrew Tze Fui Liew et al.
    Inside the acidic vacuole, expression, DNA binding and DNA binding affinity of the Salmonella regulator SsrB is stimulated by acid pH.

    Modeling Hsp70/Hsp40 interaction by multi-scale molecular simulations and coevolutionary sequence analysis

    Duccio Malinverni et al.
    Integration of complementary computational approaches reveals an evolutionarily conserved interaction interface between molecular chaperones Hsp70 and Hsp40, rationalizing previous observations.

    Labeling proteins inside living cells using external fluorophores for microscopy

    Kai Wen Teng et al.
    A toxin is used to introduce an otherwise cell-impermeant fluorophore-antibody (or some thing which is equally specific) to bind to an intracellular protein which allows for super resolution imaging and single particle tracking inside the living cell.

    An atomic-resolution view of neofunctionalization in the evolution of apicomplexan lactate dehydrogenases

    Jeffrey I Boucher et al.
    The convergent evolution of unusually strict substrate specificity in apicomplexan LDHs arose by classic neofunctionalization of a duplicated MDH gene via few mutations of large effect.

    Ribozyme-catalysed RNA synthesis using triplet building blocks

    James Attwater et al.
    Adopting RNA trinucleotides as substrates, ribozymes can catalyse the copying of structured RNA sequences, allowing self-synthesis by part of a newly evolved symbiotic ribozyme pair.

    Quiescence unveils a novel mutational force in fission yeast

    Serge Gangloff et al.
    The quiescence-driven mutational landscape reveals replication-independent mutagenesis as a novel evolutionary force.
