    New footprints from Laetoli (Tanzania) provide evidence for marked body size variation in early hominins

    Fidelis T Masao et al.
    Bipedal footprints made 3.66 million years ago provide the clearest available evidence to date of the occurrence of marked body size variation in Australopithecus afarensis..

    Protein sequences bound to mineral surfaces persist into deep time

    Beatrice Demarchi et al.
    A chemically unstable ostrich eggshell peptide survives for at least 3.8 million years at the equator, stabilized by strong mineral interactions.

    Drosophila TRIM32 cooperates with glycolytic enzymes to promote cell growth

    Simranjot Bawa et al.
    TRIM32-mediated glycolytic flux generates precursors that are utilized for biomass production in non-dividing muscle, brain and tumor cells, demonstrating a universal metabolic function for TRIM32 in cell growth.

    Shear stress activates ADAM10 sheddase to regulate Notch1 via the Piezo1 force sensor in endothelial cells

    Vincenza Caolo et al.
    Cell protease and cell fate decisions are regulated by a bone fide force-sensor, the Piezo1 channel, and by this means achieve integration with the mechanical environment.

    Aurora kinase A localises to mitochondria to control organelle dynamics and energy production

    Giulia Bertolin et al.
    AurkA is imported into mitochondria at interphase, and it induces organelle elongation and enhances ATP production when over-expressed.

    Developmentally regulated Tcf7l2 splice variants mediate transcriptional repressor functions during eye formation

    Rodrigo M Young et al.
    The inclusion of a new alternatively spliced exon in Tcf7l2 can switch its function to repress transcription of Wnt target genes.

    Palaeogenomes of Eurasian straight-tusked elephants challenge the current view of elephant evolution

    Matthias Meyer et al.
    DNA sequences from the Middle Pleistocene reveal that the extinct Eurasian straight-tusked elephants were closely related to today's African forest elephants (Loxodonta cyclotis) in Africa.
