It has been known for some time that at least some dinosaurs, including the direct ancestors of modern birds, were also endotherms. </span></span></span></span></span></span></span></span></p> September 07, 2023 - 12:09pm Andy Fell /blog/reanalysis-shows-dinosaurs-not-so-warm-blooded /news/computer-model-crystal-ball-e-coli-bacteria <p>It’s difficult to make predictions, especially about the future, and even more so when they involve the reactions of living cells — huge numbers of genes, proteins and enzymes, embedded in complex pathways and feedback loops. Yet researchers at the University of California, Davis, Genome Center and Department of Computer Science are attempting just that, building a computer model that predicts the behavior of a single cell of the bacterium <em>Escherichia coli</em>.</p> <p>The results of their work were published Oct. 7 in the journal <em>Nature Communications</em>.</p> October 27, 2016 - 10:46am Andy Fell /news/computer-model-crystal-ball-e-coli-bacteria
