The Doomsday Clock is an internationally recognized design that conveys how close we are to destroying our civilization with dangerous technologies of our own making. First and foremost among these are nuclear weapons, but the dangers include climate-changing technologies, emerging... Read More
The latest reports from the Intergovernmental Panel on Climate Change (IPCC) include an assessment of geoengineering—methods for removing carbon dioxide from the atmosphere, or cooling the Earth by reflecting more of the sun’s radiation back into space.
Calls for public participation in climate engineering research and governance have appeared in numerous scientific and policy reports on the topic, indicating a desire for transparency and public oversight.
Many countries have long pursued fast neutron breeder reactors, which create more fissile fuel than they consume, because of the expectation that the world will run out of the low-cost uranium used for fuel in most commercial nuclear power reactors.
For decades before it was selected for closure, the Treasure Island Naval Station in San Francisco Bay overhauled military ships and housed nuclear war academies that used radium, plutonium, and cesium 137 in their training courses.
This book excerpt argues that the growth of nuclear weapons technology has concentrated the power to kill entire populations in the executive branch and made the US president effectively an elected monarch.
Recent protests against the exclusion of Chinese scientists from an international conference held in the United States only scratch the surface of the formal and informal system of controls now in place to limit the access of foreign visitors to knowledge production at US research sites.
Russia has taken important steps in modernizing its nuclear forces since early 2013, including the continued development and deployment of new intercontinental ballistic missiles (ICBMs), construction of ballistic missile submarines, and development of a new strategic bomber.
As of December 1, 2013, a total of 429 nuclear reactors were considered operational in 31 countries. The nuclear industry is in decline, however, with global electricity generation from nuclear power plants down by a record 7 percent in 2012.
Despite uncertainty in defense funding levels, several emerging technology areas could shape the US military over the next decade or so, including unmanned systems, autonomous systems, cyber weaponry, three-dimensional printing, and directed-energy weapons.
The United States has an estimated 4,650 nuclear warheads available for delivery by more than 800 ballistic missiles and aircraft. Approximately 2,700 retired but still intact warheads await dismantlement, for a total inventory of roughly 7,400 warheads.
