We estimated global 2023 methane emissions from energy sector point sources using the high spatial resolution GHGSat satellite constellation. GHGSat detected 8.30 ± 0.24 million tonnes per year of methane emissions from 3114 emission sites. Detected oil and gas– and coal-emitting sites were found to be emitting 16 and 48% of the time。

gas， SIMONA GRAZIOLI， BLAISE FLEURY， we report the observation of Shapiro steps in periodically driven Josephson junctions between strongly interacting Fermi superfluids of ultracold atoms. The height and the width of the observed quantized plateaus in the current-potential characteristics mirror the external drive frequency and the junction nonlinear response. Direct measurements of the current-phase relationship showcase how Shapiro steps arise from the synchronization between the relative phase of the two reservoirs and the external drive. Such a mechanism is further supported by the detection of periodic phase-slippage processes，电流—相位关系的直接测量表明，6778期 物理学Physics Shapiro steps in strongly-interacting Fermi gases 强相互作用费米气体中的夏皮罗阶跃 ▲ 作者：GIULIA DEL PACE。
