Testing the impact of overt and covert ordering interventions on sustainable consumption choices: A randomised controlled trial.

Food products have significant impacts on the environment over their life cycle. We investigated whether displaying products in ascending order of carbon footprint in an online supermarket environment can shift consumer choices towards more sustainable options. We examined whether the effect of the ordering intervention differs when the ordering is overt (information about the ordering is explicit), compared to when it is covert (participants not told about the ordering).

Haloarchaea swim slowly for optimal chemotactic efficiency in low nutrient environments.

Archaea have evolved to survive in some of the most extreme environments on earth. Life in extreme, nutrient-poor conditions gives the opportunity to probe fundamental energy limitations on movement and response to stimuli, two essential markers of living systems. Here we use three-dimensional holographic microscopy and computer simulations to reveal that halophilic archaea achieve chemotaxis with power requirements one hundred-fold lower than common eubacterial model systems.

Traffic light labelling of meals to promote sustainable consumption and healthy eating.

The focus of the present study is to examine the impact of behavioral interventions designed to encourage consumer change around food choices in line with more sustainable consumption as well as healthy eating. More specifically, as a potential method of persuasion, we test the effect of the provision of information using traffic light labelling attached to different meal options signalling their impact on the environment (e.g.

Cell morphology governs directional control in swimming bacteria.

The ability to rapidly detect and track nutrient gradients is key to the ecological success of motile bacteria in aquatic systems. Consequently, bacteria have evolved a number of chemotactic strategies that consist of sequences of straight runs and reorientations. Theoretically, both phases are affected by fluid drag and Brownian motion, which are themselves governed by cell geometry.

Giving birth: the voices of Ecuadorian women.

Purpose: The purpose of this ethnographic study was to describe the perceptions of Ecuadorian childbearing women

Background: No studies published in English could be found documenting the perspectives of Ecuadorian childbearing women about their birth experiences.

Method: Thirty-two women who had recently given birth in Guayaquil, Ecuador participated in audiotaped interviews, which were analyzed as appropriate for ethnographic inquiry.

Results: "Enduring birth to obtain the gift" was the overarching theme.

Disruption of polycystin-1 function interferes with branching morphogenesis of the ureteric bud in developing mouse kidneys.

The polycystic kidney disease (PKD1) gene-encoded protein, polycystin-1, is developmentally regulated, with highest expression levels seen in normal developing kidneys, where it is distributed in a punctate pattern at the basal surface of ureteric bud epithelia. Overexpression in ureteric epithelial cell membranes of an inhibitory pMyr-GFP-PKD1 fusion protein via a retroviral (VVC) delivery system and microinjection into the ureteric bud lumen of embryonic day 11 mouse metanephric kidneys resulted in disrupted branching morphogenesis. Using confocal quantitative analysis, significant reductions were measured in the numbers of ureteric bud branch points and tips, as well as in the total ureteric bud length, volume and area, while significant increases were seen as dilations of the terminal branches, where significant increases in outer diameter and volumes were measured.
