The Focus article "Double Exposure" [EHP 107:A196-A201 (1999)] mistakenly reported that a meta-analysis of epidemiology studies examining the relationship between exposure to environmental tobacco smoke (ETS) and human cancer was prepared for the review of ETS in consideration for listing in the National Toxicology Program (NTP) Report on Carcinogens. We would like to point out that the results...

Transit directions at global scale

In this article I present a novel approach to integrated ground and air public transport journey planning, operating at continent scale. Flexible date search, prerequisite for long distance trips given their typical low and irregular service frequencies, is core functionality. The algorithm, best described as timed branch-and-bound (BBtime), is especially suited for irregular and poorly structu...

As a sensitive and selective analytical technique, gold nanoparticles-based colorimetric sensing was characterized by its simplicity and cost-effectiveness. Specific methods have been extensively developed for different targets in diverse samples. In this study, a label-free method for sensing Co in aqueous solutions was described. The target was achieved by the induced aggregation of thiosulfa...
