Following this commentary is a short ‘manifesto’ piece on creating ‘concrete’ texts in ‘natural’ environments or environments in which the ‘natural world’ intervenes, ‘intrudes’, or defines the conditions of viewing. This necessitates a lot of scare quotes because of the problem of mediating the ‘natural’ in the context of human seeing, perception and activity. All human activity is contingent on the ‘natural world’, regardless of how much it attempts to distance itself from the materials and variables of its construction. In the case of the images below, it might entail a spider or some other creature walking over a sheet of paper displaying a poem – the poem/sheet placed on the ground (or elsewhere) in the expectation that something will cross its path, literally. The patience is in waiting to capture the photograph, to watch the patterns of place fluctuate....

Regenerative architecture seeks to impact positively on the environment. It aims to produce buildings that reduce the degenerative consequences of human activity and add positively to the environment. To add value, in dimensions such as beauty, included in the design approaches of regenerative architecture, and in, for example, the Living Building Challenge, where the biophilic and biomimetic are raised as aspirations, however, poses some fundamental questions for the ways of thinking that underlie regenerative architecture and the discipline of architecture. Design tools suggest that the "greater than character" can be determined, measured even, in all categories, but aspirations also call for radical changes to the way we see and understand human lives. Understandings of aesthetics and the primacy of a sensory connection with the environment are little acknowledged questions within the philosophy of regenerative design outside the suggestion of biophilia. In this paper, I examine the foundations of environmental aesthetics: stories, myths, dreams and the importance of the creative imagination in understanding and reevaluating the way we see and understand human lives and our relationship to our built and natural environments.

Agmenellum quadruplicatum is a unicellular, non-nitrogen-fixing, marine cyanobacterium (blue-green alga). The ultrastructure of this organism, when grown in the laboratory with all necessary nutrients, has been characterized thoroughly. In contrast, little is known of its ultrastructure in the specific nutrient-limiting conditions typical of its natural habitat. Iron is one of the nutrients likely to limit this organism in such natural environments. It is also of great importance metabolically, being required for both photosynthesis and assimilation of nitrate. The purpose of this study was to assess the effects (if any) of iron limitation on the ultrastructure of A. quadruplicatum. It was part of a broader endeavor to elucidate the ultrastructure of cyanobacteria in natural systemsActively growing cells were placed in a growth medium containing 1% of its usual iron. The cultures were then sampled periodically for 10 days and prepared for thin sectioning TEM to assess the effects of iron limitation.

Ecological Momentary Assessment (EMA) is a way of collecting data in people’s natural environments in real time and has become very popular in social and health sciences. The emergence of personal digital assistants has led to more complex and sophisticated EMA protocols but has also highlighted some important drawbacks. Modern cell phones combine the functionalities of advanced communication systems with those of a handheld computer and offer various additional features to capture and record sound, pictures, locations, and movements. Moreover, most people own a cell phone, are familiar with the different functions, and always carry it with them. This paper describes ways in which cell phones have been used for data collection purposes in the field of social sciences. This includes automated data capture techniques, for example, geolocation for the study of mobility patterns and the use of external sensors for remote health-monitoring research. The paper also describes cell phones as efficient and user-friendly tools for prompt manual data collection, that is, by asking participants to produce or to provide data. This can either be done by means of dedicated applications or by simply using the web browser. We conclude that cell phones offer a variety of advantages and have a great deal of potential for innovative research designs, suggesting they will be among the standard data collection devices for EMA in the coming years.
