Toward a Nuclear Weapon Free World―Nuclear Disarmament Conference toward Global Zero

A global rush toward nuclear energy.

Science serves its readers as a forum for the presentation and discussion of important issues related to the advancement of science, including the presentation of minority or conflicting points of view, rather than by publishing only material on which a consensus has been reached. Accordingly, all articles published in Science-including editorials, news and comment, and book reviews-are signed ...

The Prospects for Global Nuclear Disarmament

Predicting the future can be a risky business, but predicting the future of nuclear disarmament is especially difficult, linked as it is to the core security concerns of very powerful countries. Not only is the subject imperfectly defined but it is constantly evolving under the influence of forces that are too numerous and too complex to allow for any confident projections. Yet because the issu...

Error-Free Transformation in Rounding Mode toward Zero

In this paper, we provide new error-free transformations for the sum and the product of two floating-point numbers. These error-free transformations are well suited for the CELL processor. We prove that these transformations are error-free, and we perform numerical experiments on the CELL processor comparing these new error-free transformations with the classic ones.

Toward a Global BRAIN Initiative

Neuroscience is entering a collaborative era in which powerful new technologies, generated by large scientific projects in many countries, will have a dramatic impact on science, medicine, and society. Coordinating these international initiatives and ensuring broad distribution of novel technologies and open accessibility of the generated data will multiply their value, while tapping creativity...
