Scent Trails: Countering Terrorism through Informed Surveillance
This paper reports the DScenT (Detecting Scent Trails) project, which brought together technologists and behavioural scientists to design and evaluate novel methods for countering terrorism in public places. Through a mixture of prototyping and empirical evaluations, we developed and assessed an immersive environment for detecting and investigating deceptive behaviours indicative of terrorist a...
متن کاملAir pollution modifies floral scent trails
Floral hydrocarbons provide essential signals to attract pollinators. As soon as they are emitted to the atmosphere, however, hydrocarbons are destroyed by chemical reactions involving pollutants such as ozone. It is therefore likely that increased air pollution interferes with pollinator attracting hydrocarbon signals. To test this hypothesis, a Lagrangian diffusion model was used to determine...
متن کاملThe interplay between scent trails and group-mass recruitment systems in ants.
Large ant colonies invariably use effective scent trails to guide copious ant numbers to food sources. The success of mass recruitment hinges on the involvement of many colony members to lay powerful trails. However, many ant colonies start off as single queens. How do these same colonies forage efficiently when small, thereby overcoming the hurdles to grow large? In this paper, we study the ca...
متن کاملBlood Scent
Blood cell production is tightly regulated by cell-intrinsic mechanisms and environmental factors. The study by Utpal Banerjee and colleagues and colleagues reveals that, in Drosophila, olfactory signals control hematopoietic progenitor maintenance, thus uncovering a physiological link between sensory perception and hematopoietic response to environmental stress.
متن کاملCrossed TRAILs
and colleagues have identified a protein called Hippi as one possible mediator of Huntington disease (HD) neuronal cell death. HD begins with expansion of the polyglutamine repeats in the huntingtin protein (Htt). This frees up Hip1 protein, which normally binds to Htt. Free Hip1 can then bind to the Hippi protein identified by Nicholson, and the two proteins join in a complex with procaspase 8...
