Escherichia coli were genetically modified to enable programmed motility, sensing, and actuation based on the density of features on nearby surfaces. Then, based on calculated feature density, these cells expressed marker proteins to indicate phenotypic response. Specifically, site-specific synthesis of bacterial quorum sensing autoinducer-2 (AI-2) is used(More)
Improving users' awareness of the imperfections in spatial data has been a research issue explored within Geographic Information Sciences (GIS) for more than 30 years. However, little practical progress has been made toward this objective. Currently, most spatial data producers document information about spatial data quality as part of metadata. However,(More)
UNLABELLED There have been many studies on the relationship between nonpathogenic bacteria and human epithelial cells; however, the bidirectional effects of the secretomes (secreted substances in which there is no direct bacterium-cell contact) have yet to be fully investigated. In this study, we use a transwell model to explore the transcriptomic effects(More)
Despite the fact that all geospatial data are, at different levels, imperfect, GIS technologies do not offer much support to GIS users to make them aware of the imperfections and potential limitations in the use of these data. Recent research progresses have been made towards the design of GIS that would take into account data quality. These approaches(More)
The ability to interconvert information between electronic and ionic modalities has transformed our ability to record and actuate biological function. Synthetic biology offers the potential to expand communication 'bandwidth' by using biomolecules and providing electrochemical access to redox-based cell signals and behaviours. While engineered cells have(More)
Bacteria secrete and recognize communication molecules to coordinate gene expression in a process known as quorum sensing (QS). Through coordinated expression, bacteria are able to influence phenotypic changes on a larger population scale, such as biofilm formation. Recent studies into interkingdom communication have found cross-talk communication among(More)
