  • A thin-film engineering method is employed to preserve high pressure solids in diamond capsules at ambient conditions, enabling tunable preserved pressures, controllable particle size, atomic-scale characterization, and potential large-scale uses.

  • Metabolism is known to be linked to lifespan in some species, though it remains unclear how this effect is mediated. Here they show that reduced pyruvate dehydrogenase (PDH) activity lowers locomotion but extends lifespan in daphnids and show that inhibition of PDH can increase lifespan in these species.

  • A study describes the synthesis, structural characterization and formation mechanism of a paracrystalline state of diamond, adding an unusual form of diamond to the family of carbon-based materials.

  • The nanostructured diamond capsule process with the inert gases solid argon and neon is demonstrated, where the trapped volatile gases could sustain their high-pressure states without confinement of conventional high-pressure vessels, opening up the possibility of in-depth investigations of high-pressure phenomena.

  • Whether a polymorphic transition exists in high entropy alloys or not remains unclear since discovery of these alloys more than a decade ago. Here authors report an irreversible polymorphic transition fromfcc to hcp in the prototype FeCoCrMnNi high entropy alloy and provide evidence for fccphase being more stable than hcp phase only at high temperatures.

  • While metallic glasses are expected to have tunable structures, these have rarely been demonstrated. Here, the authors combine temperature and pressure to show a two-way structural tuning in rare earth-based metallic glasses beyond the nearest-neighbor atomic shells.

  • Diamond’s properties are dictated by its crystalline, fully tetrahedrally bonded structure. Here authors synthesize a bulk sp 3-bonded amorphous form of carbon under high pressure and temperature, show that it has bulk modulus comparable to crystalline diamond and that it can be recovered under ambient conditions.

  • Through the approach of paracrystallization under high-pressure and high-temperature conditions, exceptional toughening has been achieved in oxide glasses by enhancing their crystal-like medium-range order structure. This discovery offers possibilities for the design of more resilient glass materials.

  • High entropy oxides can exhibit remarkable properties which may be amenable to pressure tuning. Here a fluorite-type high entropy oxide is shown to undergo pressure-induced lattice distortion with associated changes to optical behaviour.

  • A thick lithosphere, prior rare Earth element fertilization of the mantle, and a pathway for magma ascent are key to the formation of the Mianning–Dechang ore belt in southwest China, according to an integration of seismic tomography with geochemical data.
