Purifying Practices: How Consumers Assemble Romantic Experiences of Nature

How to Assemble a Capsid

Retroviral capsids are composed of hexagonal arrays of the viral CA protein. In this issue of Cell, Ganser-Pornillos et al. (2007) provide a molecular model of the hexagonal HIV-1 CA lattice obtained from a new electron cryomicroscopic reconstruction. This study reveals the three principal stabilizing interfaces in the capsid lattice and explains how two different classes of inhibitors can bloc...

Molecular Tinkertoys and How to Assemble Them

| We propose a systematic method of synthesizing robust macromolecules of any desired shape with precise and total structural control. It involves assembly of 3D objects from a few fundamental and carefully designed \molecular building blocks" in a \treelike leaf-to-root" fashion, followed by a later \global rigidizing" reaction. We propose three diierent sets of abstract primitive operations, ...

Metaphoric Worlds: Conceptions of a Romantic Nature [Review]

Experiences Assessing Agile Practices

Agile practices are increasingly being added to software engineering curricula, notably pair programming and test-driven development. Continuous integration is less commonly included, although the procedure of short-cycle rebuilds and test of applications is common practice in industry. This paper describes a study in which computing undergraduates were given experience of a set of agile practi...

New Methods for Assessing the Fascinating Nature of Nature Experiences

In recent years, numerous environmental psychology studies have demonstrated that contact with nature as opposed to urban settings can improve an individual's mood, can lead to increased levels of vitality, and can offer an opportunity to recover from stress. According to Attention Restoration Theory (ART) the restorative potential of natural environments is situated in the fact that nature can...
