Christopher Benjamin's Eco-Innovators: Sustainability in Atlantic Canada: stories to change minds and move hearts

In his 2011 book, Eco-Innovators: Sustainability in Atlantic Canada, environmental journalist Chris Benjamin provides a new kind of roadmap to a more sustainable future.  In this work, Chris masterfully weaves the stories of 35 creative and dedicated individuals from the four Maritime Provinces who recognize the need to take action now. From more sustainable food, transportation, or housing choices, to new business models, to community-based social marketing and branding, to journalists and educators raising their voices for change, Chris outlines some of the many narratives for change. In so doing, he offers workable options that inspire pro-environment attitude and behaviour change, at the individual, organizational, and systemic levels

Sustainability through Urban Gardening

Three visions of attaining sustainability through urban gardening – at the individual, community, and city level – are explored visually by MacEwan University Design Studies students–Molly Kassian, Nick Larson, and Sherece Burma–in their final project for Visual Communications Photography (VCPH) 340, Documentary Photography. This article emphasizes the process through which these students decided upon their project, located and interviewed their subjects, and created their visual composition. It also outlines the students’ increased awareness of, interest in, and ease with which urbanites and suburbanites can find or grow their own food

Engineering biomolecular microenvironments for cell instructive biomaterials

Engineered cell instructive microenvironments with the ability to stimulate specific cellular responses is a topic of high interest in the fabrication and development of biomaterials for application in tissue engineering. Cells are inherently sensitive to the in vivo microenvironment that is often designed as the cell “niche”. The cell “niche” comprising the extracellular matrix and adjacent cells, influences not only cell architecture and mechanics, but also cell polarity and function. Extensive research has been performed to establish new tools to fabricate biomimetic advanced materials for tissue engineering that incorporate structural, mechanical and biochemical signals that interact with cells in a controlled manner and to recapitulate the in vivo dynamic microenvironment. Bioactive tunable microenvironments using micro and nanofabrication have been successfully developed and proven to be extremely powerful to control intracellular signaling and cell function. This review is focused in the assortment of biochemical signals that have been explored to fabricate bioactive cell microenvironments and the main technologies and chemical strategies to encode them in engineered biomaterials with biological information.The authors thank Fundacao para a Ciencia e Tecnologia for C.A.C.'s PhD grant (SFRH/BD/61390/2009).

Recent advances in glycopolypeptide synthesis

Glycosylated peptides and proteins are ubiquitous in nature and display a wide range of biological functions including mediation of recognition events, protection from proteases, and lubrication in eyes and joints. Similarly, synthetic glycopolypeptides are also expected to show great potential as biomedical materials (e.g. scaffolds for tissue repair and drug carriers), as well as serve as valuable tools for probing carbohydrate-protein interactions. Although block copolypeptides and other complex polypeptide architectures have been known for some time, the synthesis of complex and well-defined glycopolypeptide materials, until recently, has been challenging. This article reviews the many advances and accomplishments made in the past few years toward development of strategies and methods for the preparation of synthetic glycopolypeptides via ring opening polymerization. © 2014 The Royal Society of Chemistry
