    A Nature paper outlines the genome sequence of a virus associated with the respiratory disease outbreak in China, isolated from a patient working in the seafood market linked to the initial cases.

    A Nature paper reports stress can cause hair to turn grey in rodents by triggering the depletion of pigment-forming stem cells in hair follicles. This effect seems to be driven by activation of the sympathetic nervous system, contrary to previous theories.

    According to research published in Nature, a protracted reduction in ocean circulation can account for much of the unusually large sea level rise during the last interglaciation.

    Convolutional neural networks are one of the most important machine learning models, commonly used to analyse images. A study published in Nature demonstrates a fully hardware-implemented convolutional neural network using memristors.

    How do cells disentangle proteins that are clumped together? A Nature paper shows that the molecular chaperone ClpB can forcibly pull on exposed loops of protein chains, and hence extract them from protein clumps.

    A Nature paper shows that a defect in the ATP13A2 gene causes cell death by disrupting the cellular transport of polyamines. When this happens in the part of the brain that controls body movement, it can lead to Parkinson’s disease.

    A Nature paper shows that the anti-diabetic drug metformin increases circulating levels of the peptide hormone growth/differentiation factor 15, which has been shown to reduce food intake and lower body weight through a brain-stem-restricted receptor.

    A study in Nature provides more details about the tiny defenders that ensure fertility by protecting the genomes of specialized cells called germ cells, which produce eggs and sperm.

    Research published in Nature pushes the precision of highly charged ion-based spectroscopy, which could be used to test for physics beyond the Standard Model.

    A Nature paper shows that glioma, a lethal form of brain cancer, alters the activity of neighboring neurons, accelerating a vicious cycle that drives tumor-associated epilepsy and tumor progression.

    Hydrogen pressured to greater than 4 million atmospheres might finally have entered the long-sought metallic state, according to a paper in Nature.

    A paper in Nature shows the process by which a sex pheromone named for Jane Austen’s Mr. Darcy takes hold in the brains of female mice, giving cells in the brain's emotion center the power to assess the mouse's sexual readiness and help her select a mate.

    A paper in Nature shows how sugar is taken up by the malaria parasite. The findings could lead to developing improved antimalarial drugs.

  14. 30. sij

    A study in Nature suggests organoid models of human brain development need improving if they are to faithfully model this early stage of life.

    Research in Nature shows that metmaterials made from LEGO that exploit a self-dual concept have emergent properties that are not predicted by standard symmetry analysis.

  16. 29. sij

    A Nature paper shows that a subset of cells from the lungs of ex-smokers have similar levels of mutations to those found in cells from non-smokers. The study suggests that quitting smoking may result in the partial replenishment of lung tissue.

    A Nature paper reports a process of using high-energy pulses of electricity to turn any source of carbon into turbostratic graphene in an instant. Graphene has been expensive, but the process could decrease the prices while helping with waste management.

    A Nature paper shows an electrical detection method for terahertz electromagnetic waves, which are extremely difficult to detect. The discovery could help miniaturize the detection equipment on microchips and enhance sensitivity.

    A new virus, originating from Wuhan in China, is quickly spreading across the country and around the world. This video highlights the key things you need to know about the outbreak and how science can help control it. The latest:
