A molecular profiling approach to quantify transcripts and proteins from identical samples allows study of molecular effects of maturation, sexual differentiation and the endogenous circalunar clock in a marine worm.
An internal clock based on brain levels of dopamine works with the circadian clock to maintain daily patterns of alertness and activity, and may be implicated in the altered behavioral patterns seen in schizophrenia and bipolar disorder.
A quantitative video tracking analysis reveals that to gain the nutrients they need, flies change their decisions to exploit foods with different nutrient contents and explore the environment according to their internal amino acid and reproductive states.
Cyanobacteria cope with both predictable day/night changes and natural fluctuations in light during the day by adjusting the expression dynamics of circadian-clock-controlled genes via a network of transcriptional regulators.
The formation of mutually exclusive coding and non-coding transcription units contributes to transcriptional interference and insulation at gene clusters and manages state-switching in response to environmental change.
