伊朗議會國家安全委員會成員賽義迪：諒解備忘錄中超過80%爲美方承諾，若美國在諒解備忘錄問題上背信棄義，伊朗也將採取對等措施。

A study in Nature reports a new quantum sensor that can effectively cancel background noise limiting measurement precision, enabling searches for previously undetectable weak signals and potentially informing the formation of supermassive black holes. Imperial College London, which led the research, said detecting the universe’s composition and new gravitational-wave sources requires measurements of extremely weak signals. Atom interferometers use interference of atomic matter waves, but the laser pulses required introduce noise that can swamp those signals and prevent meaningful data.
