摘要:The historical association of time with the rotation of Earth has meant that Coordinated Universal Time (UTC) closely follows this rotation(1). Because the rotation rate is not constant, UTC contains discontinuities (leap seconds), which complicates its use in computer networks(2). Since 1972, all UTC discontinuities have required that a leap second be added(3). Here we show that increased melting of ice in Greenland and Antarctica, measured by satellite gravity(4,5), has decreased the angular...

摘要:Polyatomic molecules have rich structural features that make them uniquely suited to applications in quantum information science1-3, quantum simulation4-6, ultracold chemistry7 and searches for physics beyond the standard model8-10. However, a key challenge is fully controlling both the internal quantum state and the motional degrees of freedom of the molecules. Here we demonstrate the creation of an optical tweezer array of individual polyatomic molecules, CaOH, with quantum control of their ...

摘要:Humans and other social animals are highly adept at learning by observing how others interact with the environment, especially when identifying potential sources of danger. In mice, a specific brain region acts as an information-processing hub that distinguishes between observed and directly experienced fear, and signals different behavioural responses accordingly.
