Ten percent o...Research finds that circadian rhythms dominate all life functions
FORT COLLINS -- New research from Colorado State University shows that the function of all genes in mammals is based on circadian -- or daily -- rhythms. The study, publishing in PLoS Computational Biology on June 15, refutes the current theory that only 10 percent to 15 percent of all genes were affected by nature's clock. While scientists have long known that circadian rhythms regulate the beh...Animal studies in the land of the midnight sun illuminate biological clocks

Answering these questions may improve our understanding of biological clocks -- the internal, genetically programmed cycle of rest and activity that affects the behavior, metabolism and physiology of all animals, including humans. A better understanding may also help solve pr...Towards a unified model of transcription termination
Dr. David Bentley (University of Colorado School of Medicine) and colleagues have developed a new, unified model for transcription termination by RNA Poymerase II. Over the years, research into the mechanism of poly(A) site-dependent transcription termination has generated two different models: the allosteric and the torpedo models. The allosteric, or antiterminator, model proposes that transcrip...Illuminating Alzheimer's: Research sheds light on creatine's presence in brain
