In 1957, Francis Crick outlined a startling vision of life in which the great diversity of forms and shapes of macromolecules was encoded in the one-dimensional sequence of nucleic acids. This paper situates Crick's new vision in the debates of the 1950s about protein synthesis and gene action. After exploring the reception of Crick's ideas, it shows how they differed radically from a different...

Topics covered: 1. Conceptual framework – agents of pattern formation. 2. Abiotic factors – geology, geomorphology, hydrology, soils. 3. Climatic factors – temperature, precipitation, solar radiation, meteorology. 4. Climate-landform effects on vegetation pattern, ecological flows, disturbance regimes and geomorphological processes. 5. Resource management implications – climate change scenarios...

Diabetes comes in many shapes and forms. It is important for the general physician to recognise when clinical characteristics, response to treatment and associated features suggest an alternative variety of diabetes, over and above the traditional type 1 and type 2 forms which are far more common. Key to these suspicions are taking a clear history of the development of the diabetes and being aw...

Background: RNA plays key role in many aspects of biological processes and its tertiary structure is critical for its biological function. RNA secondary structure represents various significant portions of RNA tertiary structure. Since the biological function of RNA is concluded indirectly from its primary structure, it would be important to analyze the relations between the RNA sequences and t...

Each form starts with a small initial ball of cells which is incrementally developed over time, adding iterative layers of complexity to the structure. The aim is to create forms emergently from the interactions between individual cells, exploring generic similarities between many different shapes in nature rather than emulating any particular organism. The process reveals universal archetypal ...

SHAPES I am currently investigating surface drawings that adopt a more abstract representation. These objects, less focused on replicating extant material forms, appear quite unlike physical sculptures or other computer graphics shapes. Figure 5 shows fthr, an example of this purely constructive process. These forms grow incrementally in a spatial balance. A salient characteristic of these obje...
