Ion collection by a conducting sphere in a magnetized or drifting collisional plasma
… by dust grains and probes in plasmas with a neutral background is of interest in the study of both space and terrestrial plasmas, where charge-exchange collisions can play an important role in ion collection. Further, background drifts or magnetic fields can significantly affect the ion …

Quantifying Intestinal Stem Cell Dynamics Using Microsatellite Sequencing
… renewal and replace each other by a pattern of neutral drift. Perturbation of these dynamics through oncogenic mutation can predispose the epithelium to neoplastic transformation. Understanding the factors that govern these dynamics will give insight into the early stages of oncogenesis. …

Paralogous genes in Arabidopsis thaliana contribute to diversified phenylpropanoid metabolism
… or subfunctionalize under selective pressure or neutral drift. Understanding the trajectory of how each gene is fixed and presumably provides added fitness remains difficult. Plant specialized metabolism provides an attractive platform to study the fixation of genes post duplication and how this …

Investigation of the Conservation of Biological Function in Transposable Elements using a Multiple Alignment Strategy
… eventually losing their ability to mobilise by neutral drift, many TEs can still persist in the human genome long after they lose their ability to transpose, suggesting the possibility of them being “domesticated”, which means that they can contribute to gene regulation via the co-option of …

Notch activation and clone fate in intestinal homeostasis and inflammation
… clones were negatively biased proximally and neutral, distally. This highlighted a disconnect between cell cycle and clone dynamics. Whilst long-term lineage tracing results show these N1ICD<sup>ΔIEC</sup> clones are all but lost from the proximal and distal colonic epithelium owing to their …
