While security risks that emanate from climate change will not always require military responses, the technnological innovations that 3D printing makes possible can significantly improve the tools available for both militaries and civilian institutions when responding to, preparing for, and mitigating those risks. These benefits come in five main forms, and this article details what they are and how each may work: Rapid response and prototyping; Democratization of preparedness and response; De-globalizing hazards; Increasing accessibility; Enhancing energy efficiency. The authors clearly believe that 3D printing will be a key tool in mitigating effects from natural disasters: 'If the United States, including the Department of Defense, truly believes that climate change presents “immediate risks to national security,” then developing all the tools necessary to combat those risks should be a high priority. 3D printing, given its potential utility in helping us adapt to and mitigate climate risks, and doing so cost-effectively, is one tool that deserves close attention.'

Amid tension between nuclear-armed nations, one side uses antisatellite weapons to disable its adversary's space assets. Is it seeking advantage in a conventional conflict, or preparing a nuclear first strike? In this scenario, the cost of miscalculation could be vast. How can the risk be mitigated? The Bulletin of the Atomic Scientists has started a debate that explores how warfare in space, which is not prohibited by the 1967 Outer Space Treaty, could lead to nuclear exchanges on earth.

Can’t remember every viral infection you’ve ever had? Don’t worry, your blood can. A new test surveys the antibodies present in a person’s bloodstream to reveal a history of the viruses they’ve been infected with throughout their life. The method could be useful not only for diagnosing current and past illnesses, but for developing vaccines and studying links between viruses and chronic disease.

Guess again!
US officials confirmed to the Guardian that in the coming days they will ask a secret surveillance court to revive the program – deemed illegal by a federal appeals court – all in the name of “transitioning” the domestic surveillance effort to the telephone companies that generate the so-called “call detail records” the government seeks to access.
The unconventional and unexpected legal circumstance depends on a section of the USA Freedom Act, which Obama signed into law on Tuesday, that provides a six-month grace period to prepare the surveillance and legal bureaucracies for a world in which the National Security Agency is no longer the repository of bulk US phone metadata.
During that time, the act’s ban on bulk collection will not yet take effect.

If additive manufacturing technologies like 3D printing are to become mainstream for complex engineering tasks – think building combat fighter aircraft wings or complete rocket engines – there needs to be a major uptick in the reliability and trustworthiness of such tools. That’s what researchers at the Defense Advanced Research Projects Agency (DARPA) aim to do with its Open Manufacturing program which this week announced new labs and other facilities that will be used to develop these additive technologies and prove whether or not they can be trusted for widespread use in complicated applications.

The FBI is operating a small air force with scores of low-flying planes across the country carrying video and, at times, cellphone surveillance technology — all hidden behind fictitious companies that are fronts for the government, The Associated Press has learned.
The planes' surveillance equipment is generally used without a judge's approval, and the FBI said the flights are used for specific, ongoing investigations. In a recent 30-day period, the agency flew above more than 30 cities in 11 states across the country, an AP review found.

China has dozens of nuclear power plants under construction and in the planning stages. India is planning its own massive expansion of nuclear generation capacity. Countries across the Middle East—from Saudi Arabia and the Gulf emirates to Tunisia and Jordan—are seriously considering the creation of nuclear power sectors. And as countries around the world make policy decisions about nuclear technology, they will also be making choices about nuclear fuel cycles and whether to reprocess spent nuclear fuel, separating out uranium and plutonium for reuse. These decisions will have major implications for international security. If the growth of nuclear power is accompanied by increased reprocessing, new stores of plutonium will be created around the world, increasing the chances that terrorists or governments could steal or divert it to make nuclear bombs.
Over the last two years, the Bulletin of the Atomic Scientists and the University of Chicago have created an online tool that will help countries understand the true cost of choosing the reprocessing route—and perhaps also help limit the spread of nuclear reprocessing. The calculator lets users test how sensitive the price of electricity is to a full range of components—more than 60 parameters that can be adjusted for the three configurations of the nuclear fuel cycle considered by this tool.

While using a laser to cut a sponge made of crumpled sheets of Graphene oxide, Researchers accidentally discovered that it can turn light into motion. As the laser cut into the material, it mysteriously propelled forward. Baffled, researchers investigated further. The Graphene material was put in a vacuum and again shot with a laser. Incredibly, the laser still pushed the sponge forward, and by as much as 40 centimeters. Researchers even got the Graphene to move by focusing ordinary sunlight on it with a lens.Though scientists are not sure why this happens, they are excited with new possibilities such as light propelled spacecraft that does not need fuel.

The Bulletin of the Atomic Scientists has launched a very cool new tool that will thrill energy wonks and anyone interested in understanding the per kilowatt cost of nuclear energy. Developed over the last two years in a partnership between the Bulletin and the University of Chicago, the Nuclear Fuel Cycle Cost Calculator estimates the cost of electricity produced by three configurations of the nuclear fuel cycle:
1. The once-through fuel cycle used in most US nuclear power plants, in which uranium fuel is used once and then stored for later disposal.; 2. A limited-recycle mode in which a mix of uranium and plutonium (that is, mixed oxide, or MOX) is used to fuel a light water reactor; 3. A full-recycle system, which uses a fast neutron spectrum reactor that can be configured to “breed” plutonium that can subsequently be used as either nuclear fuel or weapons material.
This online tool lets users test how sensitive the price of electricity is to a full range of components—more than 60 parameters that can be adjusted for the three configurations of the nuclear fuel cycle considered. The results provide nuanced cost assessments for the reprocessing of nuclear fuel and can serve as the basis for discussions among government officials, industry leaders, and public interest groups.

Is Elon Musk's new PowerWall a Game Changer? Maybe yes and maybe no: 'But fantastic battery storage doesn’t actually lower the cost of renewable energy. It doesn’t decrease the amount of energy that needs to be produced. Nor does it increase renewable’s low capacity factor or its low efficiency.' The author ultimately decides that the PowerWall could allow countries to install a really low-carbon energy mix, but cautions: 'But let’s not confuse a great battery with solving the real problems of our energy future.'

A devastating read by Robert Alvarez, a senior scholar at the Institute for Policy Studies and a former senior policy adviser to the Energy Department's secretary and deputy assistant secretary for national security and the environment. Alvarez details the horrific consequences of nuclear weapons testing in the Marshall Islands and explains the lawsuits the Marshallese have filed against the nuclear weapons states. The lawsuits hope to close the huge loophole those states carved for themselves with the vague wording of Article VI of the NPT (Nuclear Non-proliferation Treaty), wording that allows those states to delay, seemingly indefinitely, implementing the disarmament they agreed to when they signed the treaty. This is a must-read article. It also has an official US Nuclear Test Film at the top of the story.

This is a fascinating read from Aaron Arnold of the Project on Managing the Atom at Harvard's Kennedy School. Arnold points out that the Iran Nuclear Framework Agreement specifies not only that international inspectors will have access to all of Iran’s nuclear facilities, but will also gain access to Iran’s nuclear supply chain, in order to verify that components and materials are not diverted to a covert facility. 'To insure additional transparency, the preliminary framework calls for a dedicated procurement channel to approve the supply, sale, and transfer of certain nuclear-related and dual-use parts, technologies, and materials on a case-by-case basis.' Arnold points out that this is a tricky area, because Iran has shown extraordinary skill at getting around financial sanctions, and it's unclear what international body will monitor Iran's financial transactions. The article then details steps that could be taken to ensure that Iran's financial transactions are transparent and cannot be used to obtain dual-use materials, including the requirement that Iran join the international Financial Action Task Force. Great read..

A recent article in the New York Times notes that the Russian state nuclear corporation Rosatom and associated firms are gaining control of a growing number of uranium resources and mining operations. The article, headlined Cash Flowed to Clinton Foundation Amid Russian Uranium Deal focuses on donations to charities connected to former US President Bill Clinton and his family, made by businessmen who stood to profit from the sale of Uranium One, a Canadian company with worldwide uranium-mining interests. But a major premise of the article is that Russian uranium control threatens the security of the global uranium supply. Steve Fetter and Erich Schneider demolish the idea that Russian control of uranium stocks is a threat to global security.

MIT's Subrata Ghoshroy deconstructs the Navy's recent claim of successful testing with the Laser Weapon System. It seems the test videos released to the press in December were nothing more than a dog and pony show with scaled-down expectations so as to appear successful: 'When they couldn’t get a laser lightweight enough to fit on a ship while still being powerful enough to burn through the metal skin of an incoming nuclear missile, they simply changed their goal to something akin to puncturing the side of an Iranian rubber dinghy.' Ghoshroy is an entertaining writer who is an 'old hand' in the laser research industry. He gives a explanation here of the history of laser weapons, and how the search for 'SWAP' continues: 'At the end of the day, good beam quality and good SWAP—size, weight and power—still determine the success or failure of a given laser weapon, and we’re just not anywhere near meeting all those requirements simultaneously.'
