Data from: Maternal provisioning is structured by species’ competitive neighborhoods

Rachel M. Germain, Tess N. Grainger, Natalie T. Jones & Benjamin Gilbert
Differential maternal provisioning of offspring in response to environmental conditions has been argued as ‘the missing link’ in plant life histories. Although empirical evidence suggests that maternal provisioning responses to abiotic conditions are common, there is little understanding of how differences in maternal provisioning manifest in response to competition. Frequency manipulations are commonly employed in ecological studies to assess the strength of interspecific competition, relative to intraspecific competition, and we used frequency manipulations to test...

Data from: Destabilizing mutations encode nongenetic variation that drives evolutionary innovation

Katherine L. Petrie, Nathan D. Palmer, Daniel T. Johnson, Sarah J. Medina, Stephanie J. Yan, Victor Li, Alita R. Burmeister & Justin R. Meyer
Evolutionary innovations are often achieved by repurposing existing genes to perform new functions; however, the mechanisms enabling the transition from old to new remain controversial. We identified mutations in bacteriophage λ’s host-recognition gene J that confer enhanced adsorption to λ’s native receptor, LamB, and the ability to access a new receptor, OmpF. The mutations destabilize particles and cause conformational bistability of J, which yields progeny of multiple phenotypic forms, each proficient at different receptors. This...

Data from: Comparative dynamics of microglialand glioma cell motility at the infiltrative margin of brain tumours

Joseph Juliano, Orlando Gil, Andrea Hawkins-Daarud, Sonal Noticewala, Russell C. Rockne, Jill Gallaher, Susan C. Massey, Peter A. Sims, Alexander R. A. Anderson, Kristin R. Swanson & Peter Canoll
Microglia are a major cellular component of gliomas, and abundant in the centre of the tumour and at the infiltrative margins. While glioma is a notoriously infiltrative disease, the dynamics of microglia and glioma migratory patterns have not been well characterized. To investigate the migratory behaviour of microglia and glioma cells at the infiltrative edge, we performed two-colour time-lapse fluorescence microscopy of brain slices generated from a platelet-derived growth factor-B (PDGFB)-driven rat model of glioma,...

Data from: Multi-behavioral endpoint testing of an 87-chemical compound library in freshwater planarians

Siqi Zhang, Danielle Hagstrom, Patrick Hayes, Aaron Graham & Eva-Maria S. Collins
There is an increased recognition in the field of toxicology of the value of medium-to-high-throughput screening methods using in vitro and alternative animal models. We have previously introduced the asexual freshwater planarian Dugesia japonica as a new alternative animal model and proposed that it is particularly well-suited for the study of developmental neurotoxicology. In this paper, we discuss how we have expanded and automated our screening methodology to allow for fast screening of multiple behavioral...

Data from: Deep neural networks for accurate predictions of crystal stability

Weike Ye, Chi Chen, Zhenbin Wang, Iek-Heng Chu & Shyue Ping Ong
Predicting the stability of crystals is one of the central problems in materials science. Today, density functional theory (DFT) calculations remain comparatively expensive and scale poorly with system size. Here we show that deep neural networks utilizing just two descriptors—the Pauling electronegativity and ionic radii—can predict the DFT formation energies of C3A2D3O12 garnets and ABO3 perovskites with low mean absolute errors (MAEs) of 7–10 meV atom−1 and 20–34 meV atom−1, respectively, well within the limits...
