    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..

    Thousands of novel translated open reading frames in humans inferred by ribosome footprint profiling

    Anil Raj et al.
    Over 7,000 novel translated sequences have been identified from human cells, including several hundred in annotated noncoding RNA, pseudogenes and de novo assembled transcripts.

    Piezo’s membrane footprint and its contribution to mechanosensitivity

    Christoph A Haselwandter, Roderick MacKinnon
    Membrane mechanics predict that the ion channel Piezo recruits the surrounding membrane to amplify its sensitivity to changes in membrane tension, with greatest sensitivity in the low-tension regime.
