Impact of genetic background and experimental reproducibility on identifying chemical compounds with robust longevity effects
Unrestricted Use
CC BY
Rating
0.0 stars

Limiting the debilitating consequences of ageing is a major medical challenge of our time. Robust pharmacological interventions that promote healthy ageing across diverse genetic backgrounds may engage conserved longevity pathways. Here we report results from the Caenorhabditis Intervention Testing Program in assessing longevity variation across 22 Caenorhabditis strains spanning 3 species, using multiple replicates collected across three independent laboratories. Reproducibility between test sites is high, whereas individual trial reproducibility is relatively low. Of ten pro-longevity chemicals tested, six significantly extend lifespan in at least one strain. Three reported dietary restriction mimetics are mainly effective across C. elegans strains, indicating species and strain-specific responses. In contrast, the amyloid dye ThioflavinT is both potent and robust across the strains. Our results highlight promising pharmacological leads and demonstrate the importance of assessing lifespans of discrete cohorts across repeat studies to capture biological variation in the search for reproducible ageing interventions.

Instruction and Pedagogy for Youth in Public Libraries
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

There seems to be little resistance to the idea that children and teens learn in public library spaces. However, many public librarians do not see themselves as teachers. This implies that much of the learning that happens in public libraries is incidental—tangential to the “real” purpose and design of these spaces and programs.

In this book, we make the case that public librarians should embrace an explicit instructional role as a core part of their professional practice. Inside, you’ll find both a comprehensive review of what is known so far about instruction for youth in public libraries and a primer on core educational concepts and frameworks for current and future public librarians. Each chapter includes real-world examples of libraries and librarians who are already practicing powerful teaching.

We hope that this text will inspire a new group of students, practitioners, and researchers to expand on our ideas, create innovative forms of teaching and learning that are unique to public libraries, and engage all children and teens in powerful and meaningful learning experiences.

Introduction to Geospatial Concepts
Unrestricted Use

Rating
0.0 stars

Data Carpentry lesson to understand data structures and common storage and transfer formats for spatial data. The goal of this lesson is to provide an introduction to core geospatial data concepts. It is intended for learners who have no prior experience working with geospatial data, and as a pre-requisite for the R for Raster and Vector Data lesson . This lesson can be taught in approximately 75 minutes and covers the following topics: Introduction to raster and vector data format and attributes Examples of data types commonly stored in raster vs vector format Introduction to categorical vs continuous raster data and multi-layer rasters Introduction to the file types and R packages used in the remainder of this workshop Introduction to coordinate reference systems and the PROJ4 format Overview of commonly used programs and applications for working with geospatial data The Introduction to R for Geospatial Data lesson provides an introduction to the R programming language while the R for Raster and Vector Data lesson provides a more in-depth introduction to visualization (focusing on geospatial data), and working with data structures unique to geospatial data. The R for Raster and Vector Data lesson assumes that learners are already familiar with both geospatial data concepts and the core concepts of the R language.
