About the cover

The exact place and time of Homo sapiens’ emergence remains obscure because the fossil record is scanty and the chronological age of many key specimens remains uncertain. In this week’s issue, Jean-Jacques Hublin and his colleagues describe new human fossils from Jebel Irhoud in Morocco; their work is accompanied by a separate report on the dating of the fossils by Shannon McPherron and his colleagues. Together they report remains of individuals in the layer dating back 300,000–350,000 years. They identify numerous features, including a facial, mandibular and dental morphology, that align the material with early or recent modern humans. They also identify more primitive neurocranial and endocranial morphology. Collectively, the researchers believe that the remains of the Jebel Irhoud hominins can be assigned to the earliest evolutionary phase of Homo sapiens.

  • Flavour-changing neutral currents making and breaking the standard model

    • F. Archilli
    • M.-O. Bettler
    • P. Owen
    • K. A. Petridis

    The standard model of particle physics is incomplete, but experimental particle decays that occur through a ‘flavour-changing neutral current’ process, which show discrepancies to standard model predictions, may offer hints to the existence of new particles.

  • A challenge to lepton universality in B-meson decays

    • Vera Lüth
    • Yutaro Sato

    Recent measurements of B-meson decays in which tau leptons are produced might challenge the standard model assumption that interactions of leptons differ only because of their different masses.

    The crystal structure of the full-length human glucagon receptor reveals the essential role of the 12-residue ‘stalk’ segment and an extracellular loop in the regulation of ligand binding and receptor activation.
