A persistent look at how tumours evade therapy
Nature News & Views
Karen Gomez & Raul Rabadan: “Understanding how resistance to chemotherapy occurs could lead to better anticancer treatments. Persister cells in tumours can contribute to this resistance. A method to characterize these cells in detail sheds light on their origins.”aRtsy: Generative Art with R and ggplot2
”aRtsy is an attempt at making generative art available for the masses in a simple and standardized format. The package provides various algorithms for creating artworks in ggplot2 that incorporate some form of randomness (depending on the set seed). Each type of artwork is implemented in a separate function.”
The newsletter now has a dedicated homepage (thisweekmathonco.substack.com), which allows us to post cover artwork for each issue. We encourage submissions that coincide with the release of a recent paper from your group.
Caption: To examine the possible causes of rapid oxygen fluctuations on a cellular level, we developed a hybrid agent-based model to generate in silico tissues with numerically stable oxygen concentrations. We then attempted to computationally reproduce the experimentally recorded fluctuations based on either varying influx of oxygen from vessels or varying uptake of oxygen from cells. In this figure we show snapshots of a simulation of varying the influx in one of our regions of interest. The panels consist of contour maps of the simulated oxygen distribution, with the vessels circled. The color scheme of the contour map corresponds to that used in EPR imaging for the partial pressure of oxygen, where cyan represents low oxygenation and white represents high oxygenation.
