Atmospheric Chemistry and Physics, 2013 Abstract. Cumulus clouds exhibit a life cycle that consists of (a) the growth phase (increasing size, most notably in the vertical direction); (b) the mature phase (growth ceases; any precipitation that develops is strongest during this period); and (c) the dissipation phase (cloud dissipates because of precipitation and/or entrainment; no more ...

Neuron, 2013 Although circadian clocks normally run with a 24 hr period, Brancaccio et al. (2013) report in this issue of Neuron that transiently activating G protein signaling can lengthen period even after the stimulus is removed, revealing an unexpected plasticity in the central brain clock.

Demonstration of a trapped-ion atomic clock in space
Nature, 2021 Atomic clocks, which lock the frequency of an oscillator to the extremely stable quantized energy levels of atoms, are essential for navigation applications such as deep space exploration1 and global navigation satellite systems2, and are useful tools ...

Journal of Memory and Language, 2003 Telling time is an exercise in coordinating language production with visual perception. By coupling different ways of saying times with different ways of seeing them, the performance of time-telling can be used to track cognitive transformations from visual to verbal information in connected speech.

The liver-clock coordinates rhythmicity of peripheral tissues in response to feeding
Nature Metabolism, 2021 The mammalian circadian system consists of a central clock in the brain that synchronizes clocks in the peripheral tissues. Although the hierarchy between central and peripheral clocks is established, little is known regarding the specificity and ...

Accurate timekeeping is controlled by a cycling activator in Arabidopsis. [PDF]
, 2013 Transcriptional feedback loops are key to circadian clock function in many organisms. Current models of the Arabidopsis circadian network consist of several coupled feedback loops composed almost exclusively of transcriptional repressors.

JILA SrI optical lattice clock with uncertainty of 2.0×10−18 [PDF]
Metrologia, 2019 We report on an improved systematic evaluation of the JILA SrI optical lattice clock, achieving a nearly identical uncertainty compared to the previous strontium record set by the JILA SrII optical lattice clock at .
