In this article, the authors review the state of the art of ocean energy in desalination. It explores different sources of energy from the ocean that include electricity generation, as well as mechanical force and thermal energy and salinity gradients that can also be directly harnessed for powering the desalination processes. They also examine recent advances in scaling up for commercial deployment and discuss relevant cost, environmental, and social concerns.

The power of Pan-Africanism as a guiding vision for the continent’s development is widely studied, mostly as an aspirational phenomenon. At worst, Pan-Africanism has often been seen as a poor imitation of American federalism or European integration. Both of these perceptions do not reflect the profound nature of the role that the ideology of Pan-Africanism played in shaping the continent’s economic transformation. 

Last week, President Trump signed a new executive order that paves the way to impose sanctions against any foreign bank that conducts business with North Korea, going well beyond current UN financial sanctions. These so-called secondary sanctions, which are penalties applied to third-party foreign banks (i.e., not directly against North Korean entities), are particularly focused on Chinese banks.

"The rise of nations such as South Korea, Singapore and China as global economic players illustrated the importance of expanding and deepening human competence. A key starting point in the growth process is recognising that building engineering capabilities offered the best opportunity for technological leapfrogging and catch-up in a variety of industries."

"...[A]ctors that employ gray tactics in cyber operations need not be successful in actually infiltrating a system to further their revisionist ambitions. Rather, the sheer ramifications from the cyber action itself, has the power to disturb a nation's psyche and challenge the geopolitical status quo."

This book explores the sources and dynamics of social opposition to innovation. It:

• Explains the roots of resistance to new technologies - and why such resistance is not always futile
• Draws on nearly 600 years of economic history to show how the balance of winners and losers shapes technological controversies
• Outlines policy strategies for inclusive innovation to reduce the risks and maximize the benefits of new technologies

ON TUESDAY, MARCH 1, 2016, Commander Scott Kelly returned home from the International Space Station after twelve months working off the Earth, for the Earth. His year in space will pay scientific and medical dividends for years to come, helping pave the way for future astronauts to travel to Mars and beyond.

Daniel Schrag, the Sturgis Hooper Professor of Geology and professor of environmental science and engineering at Harvard, is the new director of the Belfer Center’s Science, Technology, and Public Policy Program (STPP). Schrag, who has a doctorate in geology, also directs the Harvard University Center for the Environment. He studies climate and climate change in the distant past and works on issues related to energy technology and policy. Schrag is also a member of President Obama’s Council of Advisors for Science and Technology.

"...[S]olving complex problems is less about generating the one right answer and more about generating solutions that may have flaws but nonetheless help you progress toward a goal."
