- We report the draft genome of the black cottonwood tree, Populus trichocarpa. Integration of shotgun sequence assembly with genetic mapping enabled chromosome-scale reconstruction of the genome. More than 45,000 putative protein-coding genes were identified. Analysis of the assembled genome revealed a whole-genome duplication event; about 8000 pairs of duplicated genes from that event survived in the Populus genome. A second, older duplication event is indistinguishably coincident with the divergence of the Populus and Arabidopsis lineages. Nucleotide substitution, tandem gene duplication, and gross chromosomal rearrangement appear to proceed substantially more slowly in Populus than in Arabidopsis. Populus has more protein-coding genes than Arabidopsis, ranging on average from 1.4 to 1.6 putative Populus homologs for each Arabidopsis gene. However, the relative frequency of protein domains in the two genomes is similar. Overrepresented exceptions in Populus include genes associated with lignocellulosic wall biosynthesis, meristem development, disease resistance, and metabolite transport.

- Rapid release of prepublication data has served the field of genomics well. Attendees at a workshop in Toronto recommend extending the practice to other biological data sets.

- The management of environmental and industrial disasters, search and rescue operations, surveillance of natural scenarios, environmental monitoring, and many other field robotics applications require high mobility and the need to reach locations that are difficult to access with ground vehicles. In many cases, the use of aerial vehicles is the best way to approach the objective to get information or to deploy instrumentation. Unmanned air vehicles (UAVs) have significantly increased their flight performance and autonomous onboard processing capabilities in the last ten years. But a single aerial vehicle equipped with a large array of different sensors of various modalities is limited at any time to a single viewpoint. A team of aerial vehicles, however, can simultaneously collect information from multiple locations and exploit the information derived from multiple disparate points. Furthermore, having a team with multiple heterogeneous aerial vehicles offers additional advantages due to the possibility of beneficial complementarities of the vehicles.

- Whiplash injury is the most common motor vehicle injury, yet it is also one of the most poorly understood. Here we examine the evidence supporting an organic basis for acute and chronic whiplash injuries and review the anatomical sites within the neck that are potentially injured during these collisions. For each proposed anatomical site—facet joints, spinal ligaments,intervertebral discs, vertebral arteries, dorsal root ganglia, and neck muscles—we present the clinical evidence supporting that injury site, its relevant anatomy, the mechanism of and tolerance to injury, and the future research needed to determinewhether that site is responsible for some whiplash injuries. This article serves as a snapshot of the current state of whiplash biomechanics research and provides a roadmap for future research to better understand and ultimately prevent whiplash injuries.
