Limits of economy and fidelity for programmable assembly of size-controlled triply-periodic polyhedra
Carlos M. Duque, Douglas M. Hal, Botond Tyukodi, Michael F. Hagan, Christian D. Santangelo, and Gregory M. Grason
We propose and investigate an extension of the Caspar-Klug symmetry principles for viral capsid assembly to the programmable assembly of size-controlled triply-periodic polyhedra, discrete variants of the Primitive, Diamond, and Gyroid cubic minimal surfaces. Inspired by a recent class of programmable DNA origami colloids, we demonstrate that the economy of design in these crystalline assemblies -- in terms of the growth of the number of distinct particle species required with the increased size-scale (e.g. periodicity) -- is comparable to viral shells. We further test the role of geometric specificity in these assemblies via dynamical assembly simulations, which show that conditions for simultaneously efficient and high-fidelity assembly require an intermediate degree of flexibility of local angles and lengths in programmed assembly. Off-target misassembly occurs via incorporation of a variant of disclination defects, generalized to the case of hyperbolic crystals. The possibility of these topological defects is a direct consequence of the very same symmetry principles that underlie the economical design, exposing a basic tradeoff between design economy and fidelity of programmable, size controlled assembly.

Data and R code for "Gut Transplants from Bees Fed an Antipathogenic Pollen Diet Do Not Confer Pathogen Resistance to Recipients"
Rachel T. Yost, Alison E. Fowler, and Lynn S. Adler
Pollinators are threatened by diverse stressors, including microbial pathogens such as Crithidia bombi. Consuming sunflower pollen dramatically reduces C. bombi infection in the bumble bee Bombus impatiens, but the mechanism behind this medicinal effect is unclear. We asked whether diet mediates resistance to C. bombi through changes in the gut microbiome. We hypothesized that sunflower pollen changes the gut microbiome, which in turn reduces Crithidia infection. To test this, we performed a gut transplant experiment. We fed donor bees either a sunflower pollen treatment or buckwheat pollen as a control treatment, and then inoculated recipient bees with homogenized guts from either sunflower-fed or buckwheat-fed donor bees. All recipient bees were then fed a wildflower pollen diet. Two days after the transplant, we infected recipients with C. bombi, and two days later, we provided another donor gut transplant. To quantify infection, we performed both fecal screens and dissections of the recipient bees. We found no significant differences in C. bombi infection intensity or presence between bees that received sunflower-fed microbiomes versus buckwheat-fed microbiomes. This suggests that sunflower pollen's effects on pathogen resistance are not mediated by gut microbiota.

Trans Women and Reproductive (In)Justice - How Race, Class, and Gender Shape Experiences of Family Formation and Parenthood
The following support document includes demographic data from my dissertation research, disaggregated to preserve the anonymity of respondents. It also includes two separate interview schedules for semi-structured interviews I conducted with trans women who were either currently parents (the first guide) or who want to be parents in the future (the second guide). My dissertation examines how race, class, and gender shape trans women’s parenting journeys. Trans women, and particularly trans women of color, experience high levels of discrimination across the contexts of employment, healthcare, and the legal system, yet remain virtually absent from contemporary research on family and parenting inequalities. I have conducted 54 semi-structured interviews with current and prospective parents across North America, including 27 white trans women and 27 trans women of color. Using the intersectional concepts of transmisogyny and racialized transmisogyny, I argue that trans women face unique barriers to parenting and becoming a parent but also share challenges with other minoritized parents. My findings speak more broadly to theory regarding the increased policing and regulation of motherhood (i.e., reproductive governance), the perceived link between motherhood and womanhood (i.e., R.W. Connell’s concept of mis/recognition), and ongoing transformations in family structure (i.e., queer and trans kinship studies). Whereas existing research on trans women often reduces them to victims of violence, my research highlights trans women’s resilience, resistance, and their ability to build families and community networks despite institutional barriers.
Historical plant sales (HPS) database: Documenting the spatiotemporal history of plant sales in the conterminous U.S.
Matthew Fertakos, Evelyn M. Beaury, Neil R. Ford, Nicole L. Kinlock, Denise W. Adams, and Bethany Bradley
The purpose of this database was to extract, standardize, and geocode the historical trade of vascular and non-vascular plant taxa sold in the horticultural industry of the conterminous United States. The HPS database aims to serve as a resource for analysis of contemporary patterns of introduced and invasive plants as well as for identifying opportunities to expand native plant sales in horticulture. Key data sources that make up this database include the Biodiversity Heritage Library's Seed and Nursery Catalog Collection, and the book Restoring American Gardens by D.W. Adams.

Filamentous bundles are ubiquitous in Nature, achieving highly adaptive functions and structural integrity from assembly of diverse mesoscale supramolecular elements. Engineering routes to synthetic, topologically integrated analogs demands precisely coordinated control of multiple filaments’ shapes and positions, a major challenge when performed without complex machinery or labor-intensive processing. Here, we demonstrate a photocreasing design that encodes local curvature and twist into mesoscale polymer filaments, enabling their programmed transformation into target 3-dimensional geometries. Importantly, patterned photocreasing of filament arrays drives autonomous spinning to form linked filament bundles that are highly entangled and structurally robust. In individual filaments, photocreases unlock paths 16 to arbitrary, 3-dimensional curves in space. Collectively, photocrease-mediated bundling establishes a transformative paradigm enabling smart, self-assembled mesostructures that mimic performance-differentiating structures in Nature (e.g., tendon and muscle fiber) and the macro-engineered world (e.g., rope).

Shifting hotspots: Climate change projected to drive contractions and expansions of invasive plant abundance ranges
Annette Evans, Evelyn M. Beaury, Peder S. Engelstad, Nathan B. Teich, and Bethany A. Bradley
This file contains maps of current and future abundance suitable habitat for 144 invasive plant species in the United States. Each tiff file represents the current or future range prediction maps of habitat suitable for supporting abundant populations (greater than or equal to 5% cover) of 144 invasive plant taxa, projected across the lower 48 States of the United States. Each tiff file is named with the USDA species code (SpCode) (see '1Species_information_Nov15.xlsx' file for full species names), with species codes followed by .2c indicating maps related to future climatic conditions under a +2oC warming scenario. Areas predicted to be climatically suitable for supporting abundant populations is based on model agreement and range from 0 (no models identify that area as suitable) to 15 (all model outputs identify the area as suitable). Values of 300 represent areas that are masked due to climate dissimilarity. See main publication for model fitting details.
