  • Food securityWeather reports aid life-or-death decisions in Africa

    The people living in sub-Saharan Africa have a life-or-death dependency on information about the weather. Knowing when, where, and what to grow or graze animals can be the difference between a bumper harvest and facing starvation. Although sub-Saharan Africa depends more directly on rainfall than any other region on Earth, the region has the fewest number of rain monitoring stations. There are also significant delays in the time between measurements being made and the resulting data being made available.

  • InfrastructureTesting the seismic strength of light frame steel construction

    A partnership of leading earthquake engineering researchers from top U.S. and Canadian universities and design professionals from the steel industry have begun the final phase of a three-year project to increase the seismic safety of buildings that use lightweight cold-formed steel for their primary beams and columns. Research to conclude with shake-table testing.

  • RoboticsSandia hosts annual Robot Rodeo

    Sandia National Laboratories is hosting the seventh annual Western National Robot Rodeo and Capability Exercise, a lively and challenging five-day event that draws civilian and military bomb squad teams from across the country to see who can most effectively defuse dangerous situations with the help of robots.

  • FrackingRisk assessment of shale gas fracking to biodiversity

    Fracking, the controversial method of mining shale gas, is widespread across Pennsylvania, covering up to 280,000 km² of the Appalachian Basin. New research explores the risks posed to biodiversity including pollution from toxic chemicals, the building of well pads and pipelines, and changes to wetlands.

  • Infrastructure protectionNew Jersey faces costly water infrastructure upgrades

    Before Hurricane Sandy hit New Jersey, state officials knew they had much work ahead of them to update the state’s water infrastructure. The damage Sandy inflicted only highlighted the inadequacies of New Jersey’s outdated wastewater, stormwater, and drinking water infrastructure. Upgrading the system will be costly, but not doing so will be costlier.

  • In the trenchesImproving close air support for faster, more precise airstrikes

    Air-ground fire coordination — also known as Close Air Support or CAS — is a dangerous and difficult business. While its tools have become more sophisticated, CAS has not fundamentally changed since the First World War. Now, Persistent Close Air Support (PCAS) program aims to improve air-to-ground fire coordination, but could revolutionize military technology development and deployment as well.

  • EngineeringU California, Berkeley students win National Student Steel Bridge Competition

    The weekend of 31 May residents of Washington State watched as engineers began erecting a temporary steel bridge over the Skagit River, to replace the 160-foot span of a 4-lane bridge that had collapsed a week earlier, after being struck by an over-height truck. Just sixty miles away, on the campus of the University of Washington in Seattle, 620 civil engineering students erected their own temporary steel bridges in a competition to demonstrate their engineering skills. For the second consecutive year and for the second time in the past seven years, a team of students from the University of California, Berkeley captured the title as champions of the ASCE/AISC National Student Steel Bridge Competition (NSSBC).

  • CybersecurityIsrael taps 10th graders’ cybersecurity skills to expand cybersecuity recruitment pool

    Israel has been subjected to a growing number of cyberattacks – and has itself used cyber-warfare against its adversaries. To make sure it stays ahead, Israel is accelerating its recruitment and development efforts in cybersecurity. Among other initiatives, the country is expanding the pool of potential cyberwarriors by going into high school classrooms to tap the cyber skills of tenth-graders.

  • DetectionDetecting explosives, not toothpaste

    Researchers want airports, border checkpoints, and others to detect homemade explosives made with hydrogen peroxide without nabbing people whose toothpaste happens to contain peroxide. This is part of the challenge faced in developing a portable sensor to detect a common homemade explosive called a FOx (fuel/oxidizer) mixture, made by mixing hydrogen peroxide with fuels.

  • EnergyEnvironmental group sues State Department for Keystone XL-related files

    The Sierra Club has announced it is suing the State Department for files related to an environmental review draft of the Keystone XL pipeline. The group tried to gain access to the files through the Freedom of Information Act, but the request was denied, so the group filed the suit on Monday in the U.S. District Court in the Northern District of California.

  • AviationTSA’s behavior detection program not cost effective: DHS IG

    DHS Inspector General (IG) has released a 41-page report last week stating that the Transportation Security Administration (TSA) cannot ensure that its behavior detection program, known as the Screening of Passengers by Observation Techniques (SPOT) is objective or cost-effective.

  • EnergyMaking jet fuel from switchgrass

    The Energy Department’s National Renewable Energy Laboratory (NREL) is partnering with Cobalt Technologies, U.S. Navy, and Show Me Energy Cooperative to demonstrate that jet fuel can be made economically and in large quantities from a renewable biomass feedstock such as switch grass. The project could spur jobs in rural America, lead to less reliance of foreign oil.

  • WarFighting effectively without committing war crimes

    Combat troops must minimize the humanness of their enemies in order to kill them. They cannot be effective fighters if they are distracted by feelings of empathy for opponents. Indifference to the enemy, rather than loathing, however, may help prevent war crimes and provide troops with a better path back to healthy civilian lives, researchers say.

  • Rare Earth elementsStudying rare Earth elements in Alaska may help make them less rare

    A unique deposit of heavy rare Earth elements (REE) at Alaska’s Bokan Mountain could help scientists understand how rare Earth element deposits form, according to new research. Rare Earth elements are important, but scarce, elements used in components in many cutting edge electronic and defense technologies.

  • In the trenchesBetter weather predictions for the U.S. Navy

    In a development that should significantly affect fleet operations, the U.S. Navy has adopted a new global weather forecasting model. The Naval Global Environmental Model (NAVGEM)could inform Navy operations for years to come. It is particularly important as U.S. fleet presence increases throughout the Asia-Pacific region, known for intense weather events like typhoons.
