STKE: How Clocks See the Light

Zebrafish circadian clocks: cells that see light.

In the classical view of circadian clock organization, the daily rhythms of most organisms were thought to be regulated by a central, 'master' pacemaker, usually located within neural structures of the animal. However, with the results of experiments performed in zebrafish, mammalian cell lines and, more recently, mammalian tissues, this view has changed to one where clock organization is now s...

see how children grow

it is necessary for community health nurses to be aware of children growth velocity as well as their height. this is a report of joan arton’s study on primary schools children. traditionally children health indicators were based on if they gain enough weight or not. although today it is proved that height is a better index for children health, but measuring height alone is not enough and growth...

Relativity - The Theory of Infinitesimal Light - Clocks

In part 1 of this paper, newly identified logical errors in the derivations that yield Einstein’s Special and General Theories of Relativity are discussed. These errors are much more significant than those identified by Fock. The basic philosophy of science used as a foundation for these theories is identified. The philosophy of the privileged observer is detailed. Part 1 concludes with a brief...

How to Synchronize Biological Clocks

This paper is concerned with a novel algorithm to study networks of biological clocks. A new set of conditions is established that can be used to verify whether an existing network synchronizes or to give guidelines to construct a new synthetic network of biological oscillators that synchronize. The methodology uses the so-called contraction theory from dynamical system theory and Gershgorin di...
