  • France reasserting its role as Africa's indispensable power

    In March this year, rebel militias, many composed of Muslim fighters from Chad and Sudan, overthrew the government, a move which has resulted in spreading lawlessness among rival warlords, with the risk of the disintegration of the country and sectarian war spilling beyond the country’s borders distinct possibilities. As was the case in Mali earlier this year, France has decided to put its foot down, sending hundreds of troops to the capital Bangui to restore order and restrain the lawless rebels. “The challenge of this intervention [in the Central African Republic],” on analyst wrote, “lies in the ‘return’ of France to the dark continent after decades of interference followed by a period of relative indifference or misstatements. If France succeeds in its Central African mission, it will have recovered a good part of its influence, positioning itself as an indispensable partner in those places where it risked becoming a vague memory.”

  • More states move to limit LPR use

    Law-enforcement units across the United States have been using license plate readers (LPRs) to monitor vehicles on public roads in order to locate missing individuals, investigate murderers, or track hit-and-run drivers. Privacy advocates are concerned with the wholesale storage of license plate information, and the fact that some municipalities have no limits on how long plate numbers can be stored. LPRs proponents are worried that the recent revelations about the NSA surveillance programs make it difficult for LPRs and other law-enforcement technology to get a fair hearing.

  • Wisconsin legislature considering restriction on LPRs

    State legislators in Wisconsin have proposed a law to limit the use of license plate readers, drawing criticism from local law enforcement. Republican state Representative David Craig, the sponsor of the proposed legislation, said: “The vast majority of [the LPR] images are becoming nothing more than a database of the whereabouts of average citizens. The time has come to ensure the civil rights of citizens are not being violated, while also ensuring law enforcement has the tools needed to effectively enforce our state’s laws.”

  • Testing explosives capability helping armor research

    In modern warfare, military vehicles use enormous armored panels to defend against weapons. Boosting protection by adding more steel, however, eventually makes equipment too heavy to use. There are other ways to defend against a weapon besides trying to stop it with just mass — smarter, more economic ways that are waiting to be discovered.

  • East Asia tensions on the rise as China plans more unilateral moves

    The Obama administration has advised American commercial airlines to comply with China’s demand to be notified in advance of all aircraft passing through China’s newly – and unilaterally — defined Air Defense Identification Zone(ADIZ). In contrast, Japan’s government has notified its commercial airlines to proceed with business as usual. Regional tensions are on the rise as China has said it expects to set up other ADIZs within the region.

  • Solar-powered, fabric-woven battery for “wearable electronics”

    Though some people already seem inseparable from their smartphones, even more convenient, wearable, solar-powered electronics could be on the way soon, woven into clothing fibers or incorporated into watchbands. This novel battery development could usher in a new era of “wearable electronics.”

  • Smart software fighting fire with #fire

    Australia’s key disaster management agencies have joined forces to tackle the problem of how to access and interpret information gathered during bushfires and other natural disasters to help emergency services save lives and property.

  • U.S., Japan reject China’s unilateral East China Sea claims

    The Chinese government this past weekend has declared the country’s Air Defense Identification Zone (ADIZ), effective immediately. The zone covers an area in the East China Sea — two-thirds the size of the United Kingdom – which includes islands claimed by both China and Japan. China calls them the Diaoyou islands, while Japan calls them the Senkaku islands. The United States and Japan said they would not abide by China’s unilateral decision, and on Tuesday the United States sent two B-52s long-range bombers to conduct “routine training mission” through the airspace China declared as its own, and did so without following China’s instructions about how aircraft should conduct themselves in that space.

  • Navy “mine-hunter” AUV sets mission-endurance record

    The U.S. Naval Research Laboratory’s (NRL) Acoustics Division, with Bluefin Robotics, executed a record setting 507 kilometer (315 mile), long-endurance autonomy research mission using its heavyweight-class mine countermeasures autonomous underwater vehicle (AUV), Reliant. NRL’s Reliant AUV, when equipped with a low frequency broadband (LFBB) sonar system, is perhaps best known as the prototype for the new U.S. Navy Knifefish mine-hunter.

  • New catalyst for cleanup of nitrites

    Nitrites and their more abundant cousins, nitrates, are inorganic compounds that are often found in both groundwater and surface water — a big problem, particularly for agricultural communities. The compounds are a health hazard, and the EPA places strict limits on the amount of nitrates and nitrites in drinking water. While it is possible to remove nitrates and nitrites from water with filters and resins, the process can be prohibitively expensive. Chemical engineers at Rice University have found a new catalyst that can rapidly break down nitrites.

  • Bottle scanning tech to enhance airport security, benefit passengers

    Los Alamos scientists have advanced a Magnetic Resonance Imaging (MRI) technology that may provide a breakthrough for screening liquids at airport security. They have added low-power X-ray data to the mix, and as a result have unlocked a new detection technology. Funded in part by the DHS’s Science and Technology Directorate (S&T), the new system is named MagRay.

  • Uranium, plutonium, heavy water … why Iran’s nuclear deal matters

    The agreement reached with Iran will limit enrichment to 5 percent U-235 and allow International Atomic Energy Agency (IAEA) inspectors regular visits (even daily) to their facilities. The inspectors can easily determine the ratios of U-235 and Pu-239 in the input fuel and waste streams via the characteristic radiation signatures of the isotopes involved. These stand out like a sore thumb to their instruments. In addition, the IAEA will measure the amount of U-235 employed at each facility to determine if any of the uranium is diverted to undisclosed locations. While this arrangement is operating it is highly unlikely that Iran will be able to build nuclear weapons.

  • Exploring “culture of surveillance” in the United States

    Recent revelations that the National Security Agency (NSA) has been analyzing the communication records of all U.S. citizens have many talking about the topic of “mass surveillance” by the government. A University of Kansas sociologist who has been documenting what he calls our “culture of surveillance” for nearly twenty years argues, however, that these developments are part of deeper social and cultural changes going on for quite some time. Professor William Staples focuses his attention on the relatively mundane techniques of keeping a close watch of people — what he has dubbed the “Tiny Brothers” — which are increasingly present in the workplace, school, home, and community.

  • The interim agreement between the P5+1 and Iran: the details

    The P5+1 countries (the United States, United Kingdom, Germany, France, Russia, and China, facilitated by the European Union) have been engaged in negotiations with Iran in an effort to reach a verifiable diplomatic resolution which would prevent Iran from obtaining a nuclear weapon. On Sunday, the P5+1 and Iran reached a set of initial understandings which halts, at least temporarily, the progress of Iran’s nuclear program and rolls it back in key respects. In return, for Iran’s concessions, and as part of this initial step, the P5+1 will provide what the agreement describes as “limited, temporary, targeted, and reversible” relief to Iran.

  • Off-shore barges considered for destroying Syria’s chemical weapons

    After failing to find a country willing to allow its territory to be used for disposing of Syria’s chemical weapons, the United States is exploring other options. Two options being seriously considered involve the destruction of Syria’s chemical weapons off shore, rather than on land. Both proposals call for removing the chemical weapons from Syria and placing them on a large barge at sea, where they would be dissolved or incinerated.
