A self-interfering clock as a "which path" witness
, 2015 We experimentally demonstrate a new interferometry paradigm: a self-interfering clock. We split a clock into two spatially separated wave packets, and observe an interference pattern with a stable phase showing that the splitting was coherent, i.e., the ...

An immune clock of human pregnancy
Science immunology, 2017 High-dimensional analysis reveals the chronology of immunological adaptations during the course of human pregnancies. Following the hand of the immunological clock Immune function is altered during pregnancy to protect the fetus from an immunological ...

Greb1 is required for axial elongation and segmentation in vertebrate embryos
Biology Open, 2020 During vertebrate embryonic development, the formation of axial structures is driven by a population of stem-like cells that reside in a region of the tailbud called the chordoneural hinge (CNH). We have compared the mouse CNH transcriptome with those of

Extracting dark matter signatures from atomic clock stability measurements
, 2017 We analyze possible effects of the dark matter environment on the atomic clock stability measurements. The dark matter is assumed to exist in a form of waves of ultralight scalar fields or in a form of topological defects (monopoles and strings).

A multi-tissue full lifespan epigenetic clock for mice
Aging, 2018 Human DNA-methylation data have been used to develop highly accurate biomarkers of aging ("epigenetic clocks"). Recent studies demonstrate that similar epigenetic clocks for mice (Mus Musculus) can be slowed by gold standard anti-aging interventions such

Evolution of clock escapement mechanisms [PDF]
FME Transactions, 2012 The paper presents and explains the evolution of details design of the clock escapement mechanisms through the ages. As particularly significant, the following mechanisms are emphasized: the crown wheel (verge & foliot), anchor recoil, deadbeat and ...

The molecular clock may be an episodic clock. [PDF]
Proceedings of the National Academy of Sciences, 1984 It is argued that the apparent constancy of the rate of molecular evolution may be an artifact due to the very slow rate of evolution of individual amino acids. A statistical analysis of protein evolution using a stationary point process as the null hypothesis leads to the conclusion that molecular evolution is episodic, with short bursts of rapid ...
