HYPOTHESIS VINDICATED. “Synthesis of the Elements in Stars, by Burbidge, Burbidge, Fowler, and Hoyle. Forty years later. “Their review provided a foundation for forty years of research in all of the aspects of low energy nuclear experiments and theory, stellar modeling over a wide range of mass and composition, and abundance studies of many hundreds of stars, many of which have shown distinct evidence of the processes suggested by B2FH.” https://lnkd.in/e7NpupH View in LinkedIn

DIRECT SELECTION OF EFFICIENCY. "Although most hypotheses assume indirect selection for evolvability, here we demonstrate that the ubiquitous, direct selection pressure to reduce the cost of connections between network nodes causes the emergence of modular networks." https://lnkd.in/eX5AfaH View in LinkedIn

COST MINIMIZATION. "The strongest evidence that biological networks face direct selection to minimize connection costs comes from the vascular system and from nervous systems, including the brain, where multiple studies suggest that the summed length of the wiring diagram has been minimized, either by reducing long connections or by optimizing the placement of neurons." https://lnkd.in/eX5AfaH View in LinkedIn

COSTS OF SIGNAL CHANGE. "Adding more connections in a signalling pathway might delay the time that it takes to output a critical response; adding regulation of a gene via more transcription factors may be difficult or impossible after a certain number of proximal DNA binding sites are occupied, and increases the time and material required for genome replication and regulation." https://lnkd.in/eX5AfaH View in LinkedIn

SELECTION ACROSS GENOME. "In this study, we analyzed genome-wide patterns of selection acting on different classes of sequences in a worldwide sample of eight strains of the model plant-pathogenic fungus Colletotrichum graminicola. We found evidence of selective sweeps, balancing selection, and positive selection affecting both protein-coding and noncoding DNA of pathogenicity-related sequences." https://lnkd.in/dPT523x View in LinkedIn
