Investigation of insect morphology by MRI: Assessment of spatial and temporal resolution
Classically, the investigation of the internal morphology of insects relies on histologic methods, e.g., the preparation of thin tissue sections. However, the preparation of serial sections is time consuming and means the irreversible loss of the animal. In the present investigation, we have analyzed the potential of NMR imaging as a tool for the morphologic classification of insects with sufficient spatial resolution. With a 512 matrix, 15 mm FOV, 200 mum slice thickness, images with an in-plane spatial resolution of 30 mum are obtained with a signal-to-noise ratio of 70. These conditions require only seven averages, resulting in an experimental time of only 50 min. Such image quality already permits the differentiation of fine structural and morphologic details such as e.g., intestinal tracts and copulation organ in a beetle. Also, wing controlling dorsal muscle groups as well as leg structures and joints are clearly distinguishable. We conclude that the spatial resolution and contrast condition of MR imaging are quite promising for the new approach of zoological insect classification using NMR imaging. Further principally available technical enhancement of sensitivity and spatial resolution will provide an attractive alternative to invasive techniques for the classification of, sometimes, rare and precious insect specimen

Systematic evolution of ligands by exponential enrichment: Chemi-SELEX
This application provides methods for identifying nucleic acid ligands capable of covalently interacting with targets of interest. The nucleic acids can be associated with various functional units. The method also allows for the identification of nucleic acids that have facilitating activities as measured by their ability to facilitate formation of a covalent bond between the nucleic acid, including its associated functional unit, and its target.Larry Gold, Bruce Eaton, Drew Smith, Matthew Wecker, Kirk Jensenhttp://www.findthatpatent.com/Systematic_evolution_of_ligands_by_exponential_enrichment:_Chemi-SELEX,6300074.htm
Toward a script theory of guidance in computer-supported collaborative learning
This article presents an outline of a script theory of guidance for computer-supported collaborative learning (CSCL). With its four types of components of internal and external scripts (play, scene, role, and scriptlet) and seven principles, this theory addresses the question how CSCL practices are shaped by dynamically re-configured internal collaboration scripts of the participating learners. Furthermore, it explains how internal collaboration scripts develop through participation in CSCL practices. It emphasizes the importance of active application of subject matter knowledge in CSCL practices, and it prioritizes transactive over non-transactive forms of knowledge application in order to facilitate learning. Further, the theory explains how external collaboration scripts modify CSCL practices and how they influence the development of internal collaboration scripts. The principles specify an optimal scaffolding level for external collaboration scripts and allow for the formulation of hypotheses about the fading of external collaboration scripts. Finally, the article points towards conceptual challenges and future research questions
