  • Ambipolar transport, necessary to realise PN-junctions, is unfortunately missing from most two-dimensional semiconductors. Here, the authors fabricate few-layer black phosphorous field-effect transistors, define PN-junctions and demonstrate full electrostatic control of the device by means of local gating.

  • As a material's thickness decreases towards the atomic-scale, dimensional confinement may promote behaviour not found in the bulk, with potential technological applications. Here, the authors study superconductivity in TaS2as it is mechanically exfoliated towards the two-dimensional limit.

  • Instead of using light to study mechanical motion, scientists have now demonstrated the use of mechanics to probe light, using an excitonic optomechanics coupling that paves the way to the implementation of cavity-free optomechanics.

  • Mechanical resonators lose energy over time due to both dissipative and dephasing processes. Schneider et al. now use a fast time-domain technique to separate the influence of these two types of mechanism, and demonstrate that at high driving power, dephasing becomes the dominant factor.

  • For bone marrow transplantation, donor hematopoietic cells are routinely mobilized from the bone marrow to the peripheral blood by the cytokine G-CSF. By studying mouse strains that respond to G-CSF with varying degrees of mobilization, Marnie A. Ryan et al. discovered that the epidermal growth factor receptor, acting in bone marrow cells, restrains this response. An inhibitor of epidermal growth factor receptor activity augmented G-CSF–induced mobilization in mice, suggesting that this approach might be clinically useful in bone marrow transplantation.

  • The ageing of haematopoietic stem cells (HSCs) might underlie immune system-associated pathologies such as autoimmunity and leukaemias in the elderly. In this Review, the authors summarize the cell-intrinsic and cell-extrinsic mechanisms that have been associated with HSC ageing and discuss how these mechanisms could be targeted to rejuvenate HSCs.
