The Marine Transportation System and the Federal Role: Measuring Performance, Targeting Improvement
Much of the freight transported within the United States, and the vast majority of that moved in international commerce, uses the nation's Marine Transportation System MTS. The system is varied and immense. It consists of thousands of miles of navigable channels, hundreds of port complexes, and thousands of terminals located...
Financing and Improving Land Access to U.S. Intermodal Cargo Hubs
This report presents guidance on the most effective strategies for financing improvements to cargo hub and intermodal freight facilities. These strategies focus on existing and emerging funding sources and on developing partnerships between government agencies, cargo hub operators and users, and local communities. After preparing an inventory of cargo hub...
Highway Research and Technology: The Need for Greater Investment
In this paper, the phrase "One needs more research" has added significance in that it represents the principal finding of this initiative. This time, the call comes from a broad representation of the highway community the owners and operators of the highways, numerous highway-related industries, and, yes, researchers. The findings...

Team Sniffs Out Process That Could Make 'Artificial Nose'
Smell receptors can now be mass produced in the laboratory, an advance that the biological engineers who developed the process say could lead to the creation of "artificial noses," a new report says. In a paper published in this week's issue of the Proceedings of the National Academy of Sciences...
Common Gene Mutation Lowers Risk for Bipolar Disorder
New research suggests that a missing section of DNA in a certain gene may hold the key to whether a person does or does not develop bipolar disorder. "[Our] findings show that a natural, common mutation in the GRIK4 gene protects against bipolar disorder," said Ben Pickard, lead author of...
To bond or not to bond may depend on common hormone gene variant: vasopressin receptor may contribute to commitment phobia
There's news for women who want a man who bonds rather than a James Bond: Scientists have identified a genetic variation that appears to weaken a man's ability to emotionally attach to one partner. The study, published online September 2 in the Proceedings of the National Academy of...
