This is a pictorial history of Jack Northrop's dream, the B-2A Spirit, a low-observable, strategic, long-range, heavy bomber with the ability to penetrate sophisticated and dense enemy air-defense shields. It is capable of all-altitude attack missions up to 50,000 feet, with a range of more than 6,000 nautical miles (nm) unrefueled, and over 10,000 nm with one refueling, giving it the ability to fly to any point in the world within hours. Stealth technology has rendered radar systems ineffective by greatly reducing their detection ranges. After ten years of service, the B-2A finally achieved full operational capability in December 2003. An assessment published by the USAF showed that two B-2As armed with precision weaponry could do the job of seventy-five conventional aircraft.

Materials with nanoscale structure (i.e. a structure of less than 100 nanometers in size) represent a new and exciting field of research. These materials can be produced in many ways, possess a number of unique properties compared with coarser-scaled structures, and have several possible applications with significant technological importance. Based on a state-of-the-art survey of research findings and commercial prospects, this new book concludes that much work remains to be done in characterizing these structures and their exceptional properties, and presents recommendations for the specific research and development activities needed to fill these gaps in our understanding.

Designed to protect the privacy of individual student test scores, grades, and other education records, the Family Educational Rights and Privacy Act (FERPA) of 1974 places limits the access of educational researches, and slows research not only in education but also in related fields, such as child welfare and health. Recent trends have converged to greatly increase the supply of data on student performance in public schools. Education policies now emphasize education standards and testing to measure progress toward those standards, as well as rigorous education research. At the same time, private firms and public agencies, including schools, have replaced most paper records with electronic data systems. Although these databases represent a rich source of longitudinal data, researchers' access to the individually identifiable data they contain is limited by the privacy protections of FERPA. To explore possibilities for data access and confidentiality in compliance with FERPA and with the Common Rule for the Protection of Human Subjects, the National Academies and the American Educational Research Association convened the Workshop on Protecting Student Records and Facilitating Education Research in April 2008.

In the early 1800s vast fortunes were made in the international fur trade, an enterprise founded upon the effort of a few hundred trappers scattered across the American West. From their ranks came men who still command respect for their daring, skill, and resourcefulness. This volume brings together brief biographies of seventeen leaders of the western fur trade, selected from essays assembled by LeRoy R. Hafen in The Mountain Men and the Fur Trade of the Far West (ten volumes, 1965–72). The subjects and authors are: Etienne Provost (LeRoy R. Hafen); James Ohio Pattie (Ann W. Hafen); Louis Robidoux (David J. Weber); Ewing Young (Harvey L. Carter); David F. Jackson (Carl D. W Hays); Milton G. Sublette (Doyce B. Nunis, Jr.); Lucien Fontenelle (Alan C. Trottman); James Clyman (Charles L. Camp); James P. Beckwourth (Delmot R. Oswald); Edward and Francis Ermatinger (Harriet D. Munnick); John Gantt (Harvey L. Carter); William W. Bent (Samuel P. Arnold); Charles Autobees (Janet Lecompte); Warren Angus Ferris (Lyman C. Pederson, Jr.); Manuel Alvarez (Harold H. Dunham); and Robert Campbell (Harvey L. Carter). Trappers of the Far West is the companion to Mountain Men and Fur Traders of the Far West.

This volume summarizes a range of scientific perspectives on the important goal of achieving high educational standards for all students. Based on a conference held at the request of the U.S. Department of Education, it addresses three questions: What progress has been made in advancing the education of minority and disadvantaged students since the historic Brown v. Board of Education decision nearly 50 years ago? What does research say about the reasons of successes and failures? What are some of the strategies and practices that hold the promise of producing continued improvements? The volume draws on the conclusions of a number of important recent NRC reports, including How People Learn, Preventing Reading Difficulties in Young Children, Eager to Learn, and From Neurons to Neighborhoods, among others. It includes an overview of the conference presentations and discussions, the perspectives of the two co-moderators, and a set of background papers on more detailed issues.
