  • Harasimov, Gorry, Welp, Penir, Horokhovskyi et al. analyse proteostasis in mammalian oocytes and ovaries: the maintenance of oocytes involves exceptional protein longevity, and many of the extremely long-lived proteins decline as the ovary ages.

  • Changes in the seasonal cycle amplitude of atmospheric CO2 (SCA) reflect large-scale changes in the global carbon cycle. This Review summarizes the positive SCA trend in the northern high latitudes, where the signal is strongest, and explores the underlying mechanisms driving the trend and their relative importance.

  • Models overestimate Arctic methane emissions compared to observations. Incorporating microbial dynamics into biogeochemistry models helps reconcile this discrepancy; high-affinity methanotrophs are an important part of the Arctic methane budget and double previous estimates of methane sinks.

  • Recent progress on terahertz-emission devices based on the high-temperature superconductor Bi2Sr2CaCu2O8+δ is reviewed. The emission mechanism is explained as a result of collective resonant modes in a stack of intrinsic Josephson junctions. Remarkable features of the linewidth, tunability, the optimum bias condition and the thermal influence are discussed.

  • A process-based carbon isotope biogeochemistry model substantially reduces uncertainty in regional and global estimates of the stable carbon isotopic composition of methane emissions from wetlands and suggests rising atmospheric concentrations are due to increased microbial emissions.
