Biological Clocks and Rhythms in Polar Organisms [PDF]
Biological clocks are universal to all living organisms on Earth. Their ubiquity is testament to their importance to life: from cells to organs and from the simplest cyanobacteria to plants and primates, they are central to orchestrating life on this ...

Biological clocks in theory and experiments [PDF]
Eukaryotes and some prokaryotes have adapted to the 24 h day/night cycle by evolving circadian clocks. The circadian clock now controls 24-hour rhythms in very many aspects of metabolism, physiology and behaviour.

The evolutionary trajectories and genetic architectures underlying ecological divergence with gene flow are poorly understood. Sympatric timing types of the intertidal insect Clunio marinus (Diptera) from Roscoff (France) differ in lunar reproductive ...

Summary: The vrille (vri) gene encodes a transcriptional repressor required for Drosophila development as well as circadian behavior in adults. Alternate first exons produce vri transcripts predicted to produce a short VRI isoform during development and ...

Circadian clock control of mRNA translation contributes to the daily cycling of a significant proportion of the cellular protein synthesis, but how this is accomplished is not understood.

Cryptochrome 1 mediates light-dependent inclination magnetosensing in monarch butterflies
Exactly how some animals use magnetic fields to navigate is a longstanding puzzle. A study using a new behavioural assay and transgenic butterflies finds the cryptochrome gene necessary for inclination-based magnetic sensing, and shows that both antennae

Understanding neuron-glia crosstalk and biological clocks in insomnia.
According to the World Health Organization, about one-third of the population experiences insomnia symptoms, and about 10-15% suffer from chronic insomnia, the most common sleep disorder. Sleeping difficulties associated with insomnia are often linked to

Towards the discovery of novel molecular clocks in Prokaryotes [PDF]
Diel cycle is of enormous biological importance as it imposes daily oscillation in environmental conditions, which temporally structures most ecosystems. Organisms developed biological time-keeping mechanisms –

Light at night disrupts biological clocks, calendars, and immune function
Light at night is a pervasive problem in our society; over 80% of the world’s population experiences significant light pollution. Exacerbating this issue is the reality that artificially lit outdoor areas are growing by 2.2% per year and continuously lit

Neurodegeneration, memory loss, and dementia: the impact of biological clocks and circadian rhythm
Introduction: Dementia and cognitive loss impact a significant proportion of the global population and present almost insurmountable challenges for treatment since they stem from multifactorial etiologies.
