Nature Communications, Published online: 04 August 2020; doi:10.1038/s41467-020-17649-9Current models of Galactic chemical evolution under predict the phosphorus we observe in our Solar System. Here, the authors show the discovery of 15 phosphorus-rich stars with a peculiar abundance pattern that challenges the present stellar nucleosynthesis theoretical predictions, but which could explain the missing source of phosphorus in the Galaxy.

Nature Communications, Published online: 04 August 2020; doi:10.1038/s41467-020-17604-8Plate tectonics necessitates mantle recycling throughout Earth’s history, yet direct geochemical evidence for mantle reprocessing remains elusive. Here, the authors present evidence of recycled supra-subduction zone mantle wedge peridotite dredged from the Mid-Atlantic Ridge near 16°30′N.

Nature Communications, Published online: 04 August 2020; doi:10.1038/s41467-020-17736-xThe human antibacterial and immunomodulatory peptide LL-37 is a hCAP-18 protein cleavage product that self-assembles. Here, the authors present the human and gorilla LL-37 (17–29) crystal structures, revealing a self-assembly of amphipathic helices into a densely packed and elongated hexameric structure with a central pore and mutagenesis experiments support the role of self-assembly for antibacterial activity.

Nature Communications, Published online: 04 August 2020; doi:10.1038/s41467-020-17646-yMetalenses that correct chromatic aberration also suffer from reduced focusing efficiency. Here, the authors introduce a Hybrid Achromatic Metalens which merges a metalens and phase plate to offer improved focusing efficiency over a broad wavelength range and diffraction limited imaging performance.

Nature Communications, Published online: 04 August 2020; doi:10.1038/s41467-020-17717-0Chemotherapy resistance in recurrent gliomas is a large hurdle for successful therapy. Here, the authors show that some recurrent gliomas harbour O-6-methylguanine-DNA methyltransferase (MGMT) genomic rearrangements, and in vitro and in vivo these contribute to temozolomide resistance.

Nature Communications, Published online: 04 August 2020; doi:10.1038/s41467-020-17628-0Molybdenum nitride is promising for catalysis, energy storage and Raman scattering, but it is synthesized under harsh conditions. Here the authors synthesize highly crystalline molybdenum nitride nanosheets using a relatively mild, non-aqueous solvothermal approach that can be extended to other nitrides.
