TL;DR: It is suggested that nonlinear phenomena may subserve individual recognition and the estimation of size or fluctuating asymmetry from vocalizations, and neurally ‘cheap’ unpredictability may serve the valuable adaptive function of making chaotic calls difficult to predict and ignore.

TL;DR: A dynamical model for the coupling of a population of circadian oscillators in the SCN is presented and experimentally testable predictions are that phases of individual cells are governed by their intrinsic periods and efficient synchronization is achieved when the average neurotransmitter concentration would dampen individual oscillators.

TL;DR: Interference with specific aspects of mPER2 phosphorylation leads to either short or long periods in oscillating fibroblasts, which explains not only the FASPS phenotype, but also the effect of the tau mutation in hamster as well as the doubletime mutants (dbtS and dbtL ) in Drosophila.

TL;DR: Multiple Arabidopsis thaliana clones from an experimental series of cDNA microarrays are evaluated in order to identify essential sources of noise in the spotting and hybridization process.

TL;DR: A two-mass model of vocal-fold vibrations is analyzed with methods from nonlinear dynamics and it is shown that a sufficiently large tension imbalance of the left and right vocal fold induces bifurcations to subharmonic regimes, toroidal oscillations, and chaos.
