The zebrafish represents a fascinating model for studying key aspects of the vertebrate
circadian timing system. Easy access to early embryonic development has made this …

Conspectus The ability to selectively and effectively control various molecular processes via
specific stimuli is a hallmark of the complexity of biological systems. The development of …

Most azobenzene-based photoswitches use UV light for photoisomerization. This can limit
their application in biological systems, where UV light can trigger unwanted responses …

Increasing the electron density in BF2-coodinated azo compounds through para-substitution
leads to a bathochromic shift in their activation wavelength. When the substituent is dimethyl …

Here we report the synthesis and characterization of a BF2–azo complex that can be
induced to isomerize without the need of deleterious UV light. The complexation of the azo …

Zebrafish represent the one alternative vertebrate, genetic model system to mice that can be
easily manipulated in a laboratory setting. With the teleost Medaka (Oryzias latipes), which …

Light affects animal physiology and behavior more than simply through classical visual,
image-forming pathways. Nonvisual photoreception regulates numerous biological systems …

Biological clocks have evolved as an adaptation to life on a rhythmic planet, synchronising
physiological processes to the environmental light–dark cycle. Here we examine circadian …

Zebrafish tissues and cells have the unusual feature of not only containing a circadian clock,
but also being directly light-responsive. Several zebrafish genes are induced by light, but …

For most species, light represents the principal environmental signal for entraining the
endogenous circadian clock. The zebrafish is a fascinating vertebrate model for studying this …
