(Making) Animal Tracks

Making Tracks: The Ontology of Rock Music

Making tracks: electronic excitation roles in forming swift heavy ion tracks.

Swift heavy ions cause material modification along their tracks, changes primarily due to their very dense electronic excitation. The available data for threshold stopping powers indicate two main classes of materials. Group I, with threshold stopping powers above about 10 keV nm(-1), includes some metals, crystalline semiconductors and a few insulators. Group II, with lower thresholds, compris...

MAKING AN EXPERIMENTAL ANIMAL MODEL FOR MULTIPLE SCLEROSIS

To understand the mechanism of Multiple Sclerosis (MS), an autoimmune demyelinating disease, the researchers developed an experimental animal model for MS, which is called EAE (Experimental Allergic Encephalomyelitis). There are several methods for inducing this animal model. In this research the active EAE, which is developed by injecting bovine myelin antigens into genetically susceptibl...

Speed-accuracy tradeoffs in animal decision making.

The traditional emphasis when measuring performance in animal cognition has been overwhelmingly on accuracy, independent of decision time. However, more recently, it has become clear that tradeoffs exist between decision speed and accuracy in many ecologically relevant tasks, for example, prey and predator detection and identification; pollinators choosing between flower species; and spatial ex...

The making of a photosynthetic animal.

Symbiotic animals containing green photobionts challenge the common perception that only plants are capable of capturing the sun's rays and converting them into biological energy through photoautotrophic CO(2) fixation (photosynthesis). 'Solar-powered' sacoglossan molluscs, or sea slugs, have taken this type of symbiotic association one step further by solely harboring the photosynthetic organe...
