Science, Technology, and Public Policy

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

On October 11, 2018, Harvard Kennedy School Professor of Practice Matthew Bunn presented "For Security's Sake: Saving U.S.-Russian Nuclear Arms Control" at Oak Ridge National Laboratory.

Congress is asserting itself by passing additional sanctions to hold Russia accountable for its meddling in U.S. elections. Now it needs to step up its work on arms control — not despite the current tensions with Russia, but because of them.

The major global nuclear powers are building up their arsenals once again, sparking fears of a new nuclear arms race. How serious is the danger? We ask Matthew Bunn, former White House adviser on Science and Technology Policy and co-principal investigator from the Belfer Centre on Managing the Atom.

Expert elicitations are now frequently used to characterize uncertain future technology outcomes. However, their usefulness is limited, in part because: estimates across studies are not easily comparable; choices in survey design and expert selection may bias results; and overconfidence is a persistent problem. The authors provide quantitative evidence of how these choices affect experts' estimates.

This document contains March 2016 updates to our database on U.S. government investments in energy research, development, demonstration, and deployment (ERD3) through the Department of Energy. The database, in Microsoft Excel format, tracks DOE appropriations from FY 1978–2016 and the 2017 budget request and includes funding for ERD3 from the American Recovery and Reinvestment Act of 2009. It also includes several charts.

In order to make R&D funding decisions to meet particular goals, such as mitigating climate change or improving energy security, or to estimate the social returns to R&D, policy makers need to combine the information provided in this study on cost reduction potentials with an analysis of the macroeconomic implications of these technological changes. The authors conclude with recommendations for future directions on energy expert elicitations.

The promise, prospects, and public policy trade-offs related to second-generation biofuels in road transport were addressed in an executive session convened at The Henry Ford Museum in Dearborn, Michigan, on April 7 and 8, 2015. The workshop brought together twenty-eight of the world's leading experts from the fields of policy, science, and business for an intensive two-day session. This report is a summary of the main points and issues raised over the two days. It has been reviewed by all the participants. The summary is intended to reflect the breadth of the discussion, rather than to suggest any form of overall consensus among the participants.
