  • Samples returned from asteroid Bennu largely comprise hydrated sheet silicates with sulfides, magnetite and carbonate that indicate alteration by a fluid that evolved from neutral to alkaline, according to a micro- and nanoscale mineralogical study.

  • In this Expert Recommendation, the authors provide a standardized nomenclature to improve the Human Phenotype Ontology tree with regard to the classification of non-syndromic male infertility. The implications of introducing this vocabulary in promoting communication across disciplines and institutions and in discovering novel genetic causes of non-syndromic male infertility are also discussed.

  • Samples from the asteroid (101955) Bennu, returned by the OSIRIS-REx mission, include sodium-bearing phosphates and sodium-rich carbonates, sulfates, chlorides and fluorides formed during evaporation of a late-stage brine.

  • Sperm use external cues to find the egg using ill-defined principles. Here the authors use holographic microscopy and optochemical tools to study sperm swimming in light-sculpted chemical 3D landscapes; they show that sperm translate the temporal stimulation pattern into multiple swimming behaviours to orient deterministically in a gradient.

  • Diogenite meteorites are thought to represent mantle rocks that formed as cumulates in magma chambers on 4 Vesta or a similar differentiated asteroid. Microstructural analysis of olivine grains from a diogenite meteorite show that the preferred orientation of their crystal lattice was formed through plastic deformation, indicating dynamic, planet-like processes in its parent body.

  • Various endogenous and pathogen-derived stimuli trigger the assembly of cytosolic multimolecular 'speck' platforms coordinated by the adapter ASC. Latz and colleagues demonstrate that ASC specks have extracellular functions that can prolong inflammation.

  • X-ray diffraction, Raman and infrared spectroscopic evidence for the inclusion of water-rich ringwoodite in diamond from Juína, Brazil, indicates that, at least locally, the Earth’s transition zone is hydrous to about 1 weight per cent.
