The chromosomal passenger complex-composed of Aurora B kinase and its regulatory subunits INCENP, Survivin, and Borealin-modulates multiple events during mitosis. In this issue, Jeyaprakash et al. (2007) report the crystal structure of the regulatory subunit complex and reveal how interactions between these proteins promote the targeting and function of the chromosomal passenger complex during ...

The number of travel-acquired dengue infections has seen a consistent global rise over the past decade. An increased volume of international passenger air traffic originating from regions with endemic dengue has contributed to a rise in the number of dengue cases in both areas of endemicity and elsewhere. This paper reports results from a network-based risk assessment model which uses internati...

Understanding air travelers’ values for aviation safety is essential to design effective and wellaccepted security measures. This study investigates changes in U.S. travelers trade-offs for passenger screening objectives using the occurrence of an international aviation incident (loss of Malaysian Airline Flight 370) as a natural experiment. We also examine how alternative screening procedures ...

This study aimed to detect and to identify the main strains of airborne microorganisms present in the Shanghai Metro system. Samples were collected using agar plates exposed to the air and microorganisms were identified using catalase, plasma coagulase and hymolytic analysis. The results show that the concentration of mildew present within a newly opened metro line was significantly higher than...

Emissions from passenger ferries operating in urban harbors may contribute significantly to emissions inventories and commuter exposure to air pollution. In particular, ferries are problematic because of high emissions of oxides of nitrogen (NOx) and particulate matter (PM) from primarily unregulated diesel engines. This paper explores technical solutions to reduce pollution from passenger ferr...

The number of travel-acquired dengue infections has been on a constant rise in the United States and Europe over the past decade. An increased volume of international passenger air traffic originating from regions with endemic dengue contributes to the increasing number of dengue cases. This paper reports results from a network-based regression model which uses international passenger travel vo...

The number and seriousness of medical problems on passenger-carrying aircraft in flight are increasing. Medical incidents occur at a rate of approximately 10-50 per million passengers carried. Medical equipment carried on commercial aircraft is limited to three items: a first-aid kit, an emergency medical kit and sometimes an automatic external defibrillator. Telephone medicine, a lower level o...
