Pattern formation by bacteria-driven flow.

Some marine bacterial species form mucosal layers, called veils, on sulfidic marine sediment. The bacteria attached to this veil actively swim and exert force on the surrounding fluid. The bacteria can break free of the veil and swim, chemotacting back to the veil. Over time the veil forms holes arranged in a hexagonal pattern. Motivated by this system, we present a simplified model to describe...

Physical mechanisms for chemotactic pattern formation by bacteria.

This paper formulates a theory for chemotactic pattern formation by the bacteria Escherichia coli in the presence of excreted attractant. In a chemotactically neutral background, through chemoattractant signaling, the bacteria organize into swarm rings and aggregates. The analysis invokes only those physical processes that are both justifiable by known biochemistry and necessary and sufficient ...

Concept Formation in Design: Towards a Loosely-Wired Brain Model

This paper presents a computationally tractable view on where simple concepts come from by proposing a paradigm for the formation of concepts based on the emergence of patterns in the representation of designs. It is suggested that these patterns form the basis of concepts. These patterns once learned are then added to the repertoire of known patterns so that they do not need to be learned agai...

Editorial: Wired for Life

Fossil fuels and fossil fuel derived chemicals are limited, non-renewable, and foreseen to run out in the near future. To find viable solutions for the production of renewable fuels and chemicals, significant efforts are being made by the scientific community. For example, some microorganisms have been shown to produce fuels or chemicals using renewable electricity charged electrodes as electro...

Wired for obesity?

The central nervous system (CNS) plays an important role in the regulation of appetite, energy expenditure, and body weight. Understanding the neural pathways involved is essential to the development of mechanismbased approaches to the prevention and treatment of obesity and diabetes (Fig. 1). Recent advances in MRI of fast acquisition sequences and image-processing software now enable us to no...
