Aaron Osgood-Zimmerman, Anoushka I. Millear, Rebecca W. Stubbs et al. | Mapping local variation in educational attainment across Africa OPEN Local-level analyses show that, despite marked progress in educational attainment from 2000 to 2015 across Africa, substantial differences persist between locations and sexes that have widened in many countries. Nicholas Graetz, Joseph Friedman, Aaron Osgood-Zimmerman et al. | Population snapshots predict early haematopoietic and erythroid hierarchies Single-cell transcriptomics, fate assays and a computational theory enable prediction of cell fates during haematopoiesis, discovery of regulators of erythropoiesis and reveal coupling between the erythroid, basophil and mast cell fates. Betsabeh Khoramian Tusi, Samuel L. Wolock, Caleb Weinreb et al. | Extreme disorder in an ultrahigh-affinity protein complex A high-affinity complex of histone H1 and prothymosin-α reveals an unexpected interaction mechanism, where the large opposite net charge enables the two proteins to remain highly disordered even in the complex. Alessandro Borgia, Madeleine B. Borgia, Katrine Bugge et al. | | An absorption profile centred at 78 megahertz in the sky-averaged spectrum The 21-cm absorption profile is detected in the sky-averaged radio spectrum, but is much stronger than predicted, suggesting that the primordial gas might have been cooler than predicted. Judd D. Bowman, Alan E. E. Rogers, Raul A. Monsalve et al. | Possible interaction between baryons and dark-matter particles revealed by the first stars The large absorption of the 21-centimetre transition of hydrogen around redshift 20 is explained by radiation from the first stars, combined with excess cooling of the cosmic gas caused by baryon–dark matter scattering. Rennan Barkana | Fast quantum logic gates with trapped-ion qubits Fast and high-fidelity two-qubit logic gates are demonstrated by using amplitude-shaped laser pulses to ensure that the gate operation is insensitive to the optical phase of the pulses. V. M. Schäfer, C. J. Ballance, K. Thirumalai et al. | Probing the interatomic potential of solids with strong-field nonlinear phononics Ultrashort mid-infrared laser pulses can drive atoms far from their equilibrium positions in LiNbO3, exciting high phonon harmonics and providing a way to map the interatomic potential. A. von Hoegen, R. Mankowsky, M. Fechner et al. | Skin electronics from scalable fabrication of an intrinsically stretchable transistor array A scalable process is described for fabricating skin-like electronic circuitry that can be bent and stretched while retaining desirable electronic functionality. Sihong Wang, Jie Xu, Weichen Wang et al. | Hadean silicate differentiation preserved by anomalous 142Nd/144Nd ratios in the Réunion hotspot source Neodymium-142 isotope data from young Réunion Island volcanic rocks reflect the effects of geological processes that occurred more than four billion years ago, showing that the deep mantle may preserve geochemical signatures of the primordial Earth. Bradley J. Peters, Richard W. Carlson, James M. D. Day et al. | Evolutionary history resolves global organization of root functional traits Analyses of a global dataset of plant root traits identify an ancestral conservative strategy based on thick roots and mycorrhizal symbiosis, and an evolutionarily more-recent opportunistic strategy of thin roots that efficiently use photosynthetic carbon for soil exploration. Zeqing Ma, Dali Guo, Xingliang Xu et al. | Circadian clock neurons constantly monitor environmental temperature to set sleep timing The DN1p clock neurons of Drosophila melanogaster continuously report temperature changes into the circadian neural network, to control the timing of sleep and activity. Swathi Yadlapalli, Chang Jiang, Andrew Bahle et al. | Mechanical regulation of stem-cell differentiation by the stretch-activated Piezo channel Stem cells of the Drosophila midgut sense mechanical signals in vivo through the stretch-activated ion channel Piezo, which is expressed on previously unidentified enteroendocrine precursor cells. Li He, Guangwei Si, Jiuhong Huang et al. | Sequences enriched in Alu repeats drive nuclear localization of long RNAs in human cells A sequence that is frequently found in Alu elements drives the localization of some long RNAs to the nucleus in human cells. Yoav Lubelsky, Igor Ulitsky | Intragenic origins due to short G1 phases underlie oncogene-induced DNA replication stress Oncogene activation results in firing of ectopic origins of replication within transcribed genes, resulting in replication stress and genome instability. Morgane Macheret, Thanos D.
