Changes in correlated activity of neurons are believed to influence their information coding capacity. Here, the authors show how top-down and bottom-up inputs and their interaction differentially alter the correlated activity of neurons in extrastriate cortex
Pre-ribosomes undergo numerous structural rearrangements during their assembly. Here the authors identify the binding sites of three essential RNA helicases on pre-ribosomal particles, enabling them to provide insights into the structural and compositional changes that occur during biogenesis of the large ribosomal subunit.
Latin Americans trace their ancestry to the admixture of Native Americans, Europeans and Sub-Saharan Africans. Here, the authors develop a novel haplotype-based approach and analyse over 6,500 Latin Americans to infer the geographically-detailed genetic structure of this population.
Millions of enhancers are predicted, but their validation remains challenging. Here, the authors report genome-wide enhancer function quantification and high-resolution dissection for millions of accessible DNA fragments, revealing driver nucleotides and helping interpret non-coding disease variants.
Quasi-1D magnetic insulators are very attractive for searching and studying quantum many-body phenomena. Here the authors report the four-spinon excitations in quasi-1D spin-chain cuprate Sr2CuO3 by momentum resolved RIXS technique which provides a new route for the creation of magnetic excitations in 1D materials.
Topological one-way fibers are promising candidates for novel fiber devices. Here, Lu et al. propose that one-way fiber modes are topologically protected by the second Chern number in a four-dimensional parameter space, which develop in a helically-modulated magnetic Weyl photonic crystal.
Atomically-clean interfaces are required in heterostructures. Here, authors report a method for fast and parallel removal of contaminants from fully-formed heterostructures, including sample intentionally exposed to polymers and solvent, achieving room temperature mobility over 180,000 cm2/Vs for graphene.
The pulvinar is involved in vision and attention, but its interactions with other brain regions are little-studied. Here, using fMRI the authors show that the human pulvinar has widespread functional coupling with cortical areas that reflects its intrinsic organization and the topographic layout of cortex.
Gelsolin is an actin severing and capping protein that regulates cytoskeletal remodeling. Here the authors show that gelsolin is negatively regulated in the heart by PI3Kα‐ generated PIP3, and that loss of gelsolin activity prevents adverse cytoskeletal remodeling and heart failure.
Type VI secretion systems (T6SSs) translocate effector proteins into eukaryotic and bacterial recipient cells and are present in many Gram-negative bacteria. Here the authors present the 3.7 Å cryoEM structure of the E.coli T6SS baseplate wedge comprising TssK–TssF–TssG and propose a model for the T6SS baseplate and needle complex.
Plasmons confined in field effect transistors were long envisioned for resonant detection of light at THz frequencies, however realization of such photodetectors has proven challenging. Here, the authors fabricate antenna-coupled graphene transistors which exhibit resonant photoresponse to incident radiation and use them to study plasmons in graphene and its moiré superlattices.
The mechanisms underlying pre-metastatic niche formation by cancer derived exosomes is unclear. Here they show that colorectal cancer (CRC) derived exosomal miR-25-3p promotes vascular leakiness and angiogenesis, CRC metastasis, and is upregulated in CRC pateints with metastasis, and suggest miR-25-3p as a biomarker for CRC metastasis.
For many applications, quantum random number generation should be fast and independent from assumptions on the apparatus. Here, the authors devise and implement an approach which assumes a trusted detector but not a trusted source, and allows random bit generations at ~17 Gbps using off-the-shelf components.
Neural activity during REM sleep is similar to the waking state. Here, the authors measure blood volume with neurofunctional ultrasound imaging together with hippocampal neural activity during REM sleep and report that fast gamma oscillations are coupled to a brain-wide upregulation of vascular flow.
RIG-I is a critical receptor in the induction of innate immune responses, but mutations in RIG-I can be associated with hyperactive signalling and autoimmune disease. Here Zheng et al. apply HDX-MS approaches to reveal dysregulated checkpoints that result in recognition of self-derived RNA during RIG-I mediated autoimmunity.
Vertical charge transport through homogeneous WSe2 layers can be effectively tuned by the layer number and contacting metals deposited. Here, the authors report WSe2 vertical diodes with superior device performance characteristics based on variable WSe2 thickness and gadolinium and platinum contact metals.
Mycobacterium ulcerans is the causative agent of Buruli ulcer (BU). Existing anti-tubercular drugs have been used to treat the condition with varying success. Here, the authors show that a clinical-stage drug candidate for tuberculosis, Q203, is effective at killing M. ulcerans and is a promising therapeutic candidate for BU.
The origins of lineage correlations and heterogeneity in division and apoptosis times among single cells are incompletely understood. Here, a new lineage tracking data analysis approach reveals that circadian oscillations may underlie cell fate control and explain the observed correlation structures.
More than 18 human papillomaviruses (HPV) are associated with cervical cancer, and ideally vaccines should protect from all of them. Here, the authors engineer a triple-type, chimeric HPV vaccine, using loop swapping, that elicits robust neutralizing antibody titers in mice and non-human primates.
Credibility of long-term projection in quantitative models is continuously under debate and they rely on validation to prove projection accuracy. Here the authors investigated the views on the validation approaches and they show that empirical data plays an important role in the validation practice in all main areas of sustainability science.
