A letter report issued by the Government Accountability Office with an abstract that begins "The abuse of anabolic steroids by teenagers--that is, their use without a prescription--is a health concern. Anabolic steroids are synthetic forms of the hormone testosterone that can be taken orally, injected, or rubbed on the skin. Although a 2006 survey funded by the National Institute on Drug Abuse (NIDA) found that less than 3 percent of 12th graders had abused anabolic steroids, it also found that about 40 percent of 12th graders described anabolic steroids as "fairly easy" or "very easy" to get. The abuse of anabolic steroids can cause serious health effects and behavioral changes in teenagers. GAO was asked to examine federally funded efforts to address the abuse of anabolic steroids among teenagers and to review available research on this issue. This report describes (1) federally funded efforts that address teenage abuse of anabolic steroids, (2) available research on teenage abuse of anabolic steroids, and (3) gaps or areas in need of improvement that federal officials and other experts identify in research that addresses teenage anabolic steroid abuse. To do this work, GAO reviewed federal agency materials and published studies identified through a literature …

Other written product issued by the Government Accountability Office with an abstract that begins "The forum's participants described nanomanufacturing as a future megatrend that will potentially match or surpass the digital revolution's effect on society and the economy. They anticipated further scientific breakthroughs that will fuel new engineering developments; continued movement into the manufacturing sector; and more intense international competition."

A letter report issued by the Government Accountability Office with an abstract that begins "In the last 5 years, the Department of Defense (DOD) has doubled its planned investments in new weapon systems from about $700 billion in 2001 to nearly $1.4 trillion in 2006. While the weapons that DOD develops have no rival in superiority, weapon systems acquisition remains a long-standing high risk area. GAO's reviews over the past 30 years have found consistent problems with weapon acquisitions such as cost increases, schedule delays, and performance shortfalls. In addition, DOD faces several budgetary challenges that underscore the need to deliver its new weapon programs within estimated costs and to obtain the most from these investments. This report provides congressional and DOD decision makers with an independent, knowledge-based assessment of selected defense programs that identifies potential risks and needed actions when a program's projected attainment of knowledge diverges from the best practices. Programs for the assessments were selected based on several factors including, (1) high dollar value, (2) stage in acquisition, and (3) congressional interest. The majority of the 52 programs covered in this report are considered major defense acquisition programs by DOD. This report also highlights higher level issues …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) is embarking on a number of efforts to enhance warfighting and the way the department conducts business. Major investments are being made to develop improved weapon systems to combat various threats to U.S. security. While the weapons that DOD ultimately develops have no rival in superiority, weapon systems acquisition remains a long-standing high-risk area. GAO's reviews over the past 30 years have found consistent problems with weapon acquisitions such as cost increases, schedule delays, and performance shortfalls. In addition, DOD faces several budgetary challenges that underscore the need to deliver its new major weapon programs within estimated costs and to obtain the most from those investments. DOD can help resolve these problems by using a more knowledge-based approach for developing new weapons. This report provides congressional and DOD decision makers with an independent, knowledge-based assessment of selected defense programs that identifies potential risks and needed actions when a program's projected attainment of knowledge diverges from the best practice. It can also highlight those programs that employ practices worthy of emulation by other programs. GAO plans to update and issue this report …

A letter report issued by the Government Accountability Office with an abstract that begins "This report is GAO's sixth annual assessment of selected weapon programs. Since 2000, the Department of Defense (DOD) has roughly doubled its planned investment in new systems from $790 billion to $1.6 trillion in 2007, but acquisition outcomes in terms of cost and schedule have not improved. Total acquisition costs for major defense programs in the fiscal year 2007 portfolio have increased 26 percent from first estimates, compared with 6 percent in 2000. Programs have also often failed to deliver capabilities when promised. DOD's acquisition outcomes appear increasingly suboptimal, a condition that needs to be corrected given the pressures faced by the department from other military and major nondiscretionary government demands. This report provides congressional and DOD decision makers with an independent, knowledge-based assessment of defense programs, identifying potential risks when a program's projected attainment of knowledge diverges from best practices. The programs assessed--most of which are considered major acquisitions by DOD--were selected using several factors: high dollar value, acquisition stage, and congressional interest. This report also highlights overall trends in DOD acquisition outcomes and issues raised by the cumulative experience of individual programs. GAO updates …
