TL;DR: The data suggest that the efficiency of mitochondrial respiration in oocytes and preimplantation embryos is closely correlated with the programmed rate of embryo development, and suggest that maternal age further influences this factor.

TL;DR: Pressure-induced amorphization is observed on films of porous Si, which contains nanometre-sized domains of diamond-structured material, and it is found from Raman spectroscopy measurements that the high-density amorphous form obtained by this process transforms to low-densityAmorphous silicon upon decompression.

TL;DR: It is reported here that the phosphoinositide messenger system oscillates during the early embryonic cell cycle in the sea urchin, leading to cyclic increases in inositol trisphosphate that trigger cell-cycle [Ca2+]i transients and mitosis by calcium release from intracellular stores.

TL;DR: At very high temperatures, yttria-alumina melts show a first-order transition, previously inferred from phase separation in quenched glasses, which is shown how the transition coincides with a narrow and reversible maximum in SAXS indicative of liquid unmixing on the nanoscale, combined with an abrupt realignment in WAXS features related to reversible shifts in polyhedral packing on the atomic scale.

TL;DR: Pressure-induced amorphization (PIA) is a phenomenon that involves an abrupt transition between a crystalline material and an amorphous solid through application of pressure at temperatures well below the melting point or glass transition range.
