  • SARS-CoV-2 vaccines in development
    Nature (IF 42.778) Pub Date : 2020-09-23
    Florian Krammer

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in late 2019 in China and caused a coronavirus disease 2019 (COVID-19) pandemic. To mitigate the public health, economic and societal impacts of the virus, a vaccine is urgently needed. The development of SARS-CoV-2 vaccines was initiated in early January 2020 when the sequence of the virus became available and moved at record speed

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the etiological agent of coronavirus disease 2019 (COVID-19), an emerging respiratory infection caused by introduction of a novel coronavirus into humans in late 2019 in China’s Hubei province. As of September 11, 2020, SARS-CoV-2 has spread to 215 countries, has infected more than 28 million people, and has caused more than 910,000 deaths

  • Third-order nanocircuit elements for neuromorphic engineering
    Nature (IF 42.778) Pub Date : 2020-09-23
    Suhas Kumar; R. Stanley Williams; Ziwen Wang

    Current hardware approaches to biomimetic or neuromorphic artificial intelligence rely on elaborate transistor circuits to simulate biological functions. However, these can instead be more faithfully emulated by higher-order circuit elements that naturally express neuromorphic nonlinear dynamics1,2,3,4. Generating neuromorphic action potentials in a circuit element theoretically requires a minimum

    More than half of Earth’s freshwater resources are held by the Antarctic Ice Sheet, which thus represents by far the largest potential source for global sea-level rise under future warming conditions1. Its long-term stability determines the fate of our coastal cities and cultural heritage. Feedbacks between ice, atmosphere, ocean, and the solid Earth give rise to potential nonlinearities in its response

    The genetic circuits that allow cancer cells to evade destruction by the host immune system remain poorly understood1,2,3.

  • Hippocampal CA2 sharp-wave ripples reactivate and promote social memory
    Nature (IF 42.778) Pub Date : 2020-09-23

    The consolidation of spatial memory depends on the reactivation (‘replay’) of hippocampal place cells that were active during recent behaviour. Such reactivation is observed during sharp-wave ripples (SWRs)—synchronous oscillatory electrical events that occur during non-rapid-eye-movement (non-REM) sleep1,2,3,4,5,6,7,8 and whose disruption impairs spatial memory3,5,6,8.

    Self-assembling colloidal particles in the cubic diamond crystal structure could potentially be used to make materials with a photonic bandgap1,2,3. Such materials are beneficial because they suppress spontaneous emission of light1 and are valued for their applications as optical waveguides, filters and laser resonators4, for improving light-harvesting technologies5,6,7 and for other applications4

    The three-dimensional organization of the genome supports regulated gene expression, recombination, DNA repair, and chromosome segregation during mitosis.

    Psychological research shows that social comparison of individuals with peers or others shapes attitude formation1,2. Opportunities for such comparisons have increased with global inequality3,4; everyday experiences can make economic disparities more salient through signals of social class5,6.

    CpG methylation by de novo DNA methyltransferases (DNMTs) 3A and 3B is essential for mammalian development and differentiation and is frequently dysregulated in cancer1. These two DNMTs preferentially bind to nucleosomes, yet cannot methylate the DNA wrapped around the nucleosome core2, and they favour the methylation of linker DNA at positioned nucleosomes3,4.

    Magnetic skyrmions are topological solitons with a nanoscale winding spin texture that hold promise for spintronics applications1,2,3,4.

    Current understandings of cell specification in early mammalian pre-implantation development are based mainly on mouse studies. The first lineage differentiation event occurs at the morula stage, with outer cells initiating a trophectoderm (TE) placental progenitor program. The inner cell mass arises from inner cells during subsequent developmental stages and comprises precursor cells of the embryo

Up to 90% of disease risk is thought to be due to environmental factors such as diet, which is consistent with a growing body of literature that describes an ‘oncogenic’ CRC-associated microbiota.

Both receptor binding and membrane fusion activities are mediated by the virus Spike glycoprotein, S5–7. As with other class I membrane fusion proteins, S is post-translationally cleaved, in this case by furin, into S1 and S2

    Neural crest cells (NCCs) are migratory, multipotent embryonic cells that are unique to vertebrates and form an array of clade-defining adult features. The evolution of NCCs has been linked to various genomic events, including the evolution of new gene-regulatory networks1,2, the de novo evolution of genes3 and the proliferation of paralogous genes during genome-wide duplication events4. However, conclusive

    The MAPK/ERK kinase MEK is a shared effector of the frequent cancer drivers KRAS and BRAF that has long been pursued as a drug target in oncology1, and more recently in immunotherapy2,3 and aging4. However, many MEK inhibitors (MEKi) are limited due to on-target toxicities5–7 and drug resistance8–10. Accordingly, a molecular understanding of the structure and function of MEK within physiological complexes

    The DNA sensor cGAS initiates innate immune responses following microbial infection, cellular stress, and cancer1. Upon activation by double-stranded DNA, cytosolic cGAS produces 2’3’ cyclic GMP-AMP and triggers inflammatory cytokine and type I interferon (IFN) induction2–7. cGAS is also present inside the cell nucleus replete with genomic DNA8, where chromatin has been implicated in restricting its

    Pathogen-derived nucleic acids induce potent innate immune responses1–6. Cyclic GMP-AMP synthase (cGAS) is a dsDNA sensor that catalyzes the synthesis of a cyclic dinucleotide cGAMP, which mediates the induction of type I interferons through the STING-TBK1-IRF3 signaling axis7–11. It was widely accepted that cGAS is not reactive to self-DNA due to its cytosolic localization2,12,13. However, recent

    cGAS (cyclic GMP–AMP synthase) is an innate immune sensor for cytosolic microbial DNA1. Upon binding DNA, it synthesizes the messenger cGAMP (2’3’ cyclic GMP–AMP)2–4, which triggers cell-autonomous defense and the production of type I interferons and pro-inflammatory cytokines via activation of STING5. Besides responding to cytosolic microbial DNA, cGAS also recognizes mis-localized cytosolic self-DNA

    Hydrogen, the simplest and most abundant element in the Universe, develops a remarkably complex behaviour upon compression1.

    The successful operation of quantum computers relies on protecting qubits from decoherence and noise, which—if uncorrected—will lead to erroneous results. Because these errors accumulate during an algorithm, correcting them is a key requirement for large-scale and fault-tolerant quantum information processors. Besides computational errors, which can be addressed by quantum error correction1,2,3,4,5

Centrosomes themselves duplicate once per cell cycle, in a process that is controlled by the serine/threonine protein kinase PLK4 (refs. 2,3). When PLK4 is chemically inhibited, cell division proceeds without centrosome duplication, generating centrosome-less cells that exhibit delayed, acentrosomal
