STEM education and U.S. national security
Los Alamos National Laboratory director Charlie McMillan will be one of seventeen speakers at this year’s TEDxABQ. TEDxABQ is an independently organized event in Albuquerque, New Mexico, affiliated with the popular TED Talks series.McMillan will discuss the linkage between early education in science, technology, engineering, and mathematics (known as STEM) and national security.

Crawling robot examines, evaluates condition of load-bearing cables
Severe weather events inflict damage and destruction. The condition of infrastructure and its components may contribute to the overall damage: weak components and damaged elements make infrastructure less likely to withstand the stress of a storm. Researchers have developed a crawling robot capable of examining and evaluating the condition of load-bearing cables, such as those found in bridges, elevators, and cable cars.

Mother Nature offers best protection for coastal communities’ infrastructure
Extreme weather, sea-level rise, and degraded coastal ecosystems are placing people and property at greater risk of damage from coastal hazards. The likelihood and magnitude of losses can be reduced by intact ecosystems near vulnerable coastal communities. Scientists say that natural habitats such as dunes and reefs are critical to protecting millions of U.S. residents and billions of dollars in property from coastal storms.

Better teaching for inquiring minds
Inquiry-based learning is an educational method centered on the investigation of questions, scenarios, or problems. It is seen by many as a positive alternative to traditional forms of instruction where students are required to simply memorize information.

Concrete recycling robot disassembles concrete structures for recycling, reuse
Current concrete-demolition techniques require a lot of power crushing, separation, and machinery, not to mention the fact that they waste a lot of water in order to prevent dust blooms during operation. A new concrete recycling robot is designed efficiently to disassemble concrete structures without any waste, dust, or separation and enable reclaimed building materials to be reused for new prefabricated concrete buildings. It does so by using a water jet to crack the concrete surface, separate the waste, and package the cleaned, dust-free material.

Climate change, severe weather threaten U.S. energy sector: Dept. of Energy
The U.S. entire energy system is vulnerable to increasingly severe and costly weather events driven by climate change, according to a U.S. Department of Energy report published last week. These climate and weather trends — increasing temperatures, decreasing water availability, more intense storm events, and sea level rise — each independently, and in some cases in combination, could restrict the supply of secure, sustainable, and affordable energy critical to U.S. economic growth.

Student teams compete in U.S. Navy’s RoboBoat competition
In a race against one another and the clock, robotic boats are battling it out at the 6th International RoboBoat Competition, which began 8 July and ends 14 July. The Office of Naval Research (ONR)-co-sponsored competition takes place on a pond at the Founder’s Inn and Spa in Virginia Beach, Virginia. The event features fifteen student teams racing their custom-designed and built boats.

DARPA’s disaster robot competition moves to final stage
On Monday, 8 July 2013, the seven teams which progressed from DARPA’s Virtual Robotics Challenge (VRC) arrived at the headquarters of Boston Dynamics in Waltham, Massachusetts to meet and learn about their new teammate, the ATLAS robot. ATLAS is one of the most advanced humanoid robots ever built, but is essentially a physical shell for the software brains and nerves that the teams will continue to develop and refine. The robot will have to perform a series of tasks similar to what might be required in a disaster response scenario.

U.S. power plants use more coal, bucking the trend toward natural gas
Power plants in the United States are burning more coal to produce electricity, bucking the trend toward using natural gas, and in the process emitting more greenhouse gasses into the atmosphere, a new government report says. Burning coal to produce electricity was popular just a few years ago, but hydraulic fracturing led to a natural gas boom, driving down gas prices and making natural gas more competitive with coal. The demand for natural gas got so high, however, that its price began to creep up at the same time that the price of coal dropped because of weakening demand for it.

Japan to restart nuclear power plants
Japan’s fifty nuclear power plants were taken off-line in the wake of the 2011 Fukushima nuclear disaster, but the government Prime Minister Shinzo Abe, which took office in December, said it was planning to restart Japan’s nuclear power generation program.

Assessing the social, economic effects of Deepwater Horizon spill
Numerous studies are under way to determine the impacts of the Deepwater Horizon oil spill on the Gulf of Mexico, but the extent and severity of these impacts and the value of the resulting losses cannot fully be measured without considering the goods and services provided by the Gulf, says a new report from the National Research Council (NRC). The report offers an approach that could establish a more comprehensive understanding of the impacts and help inform options for restoration activities.

Wildfires contribute more to global warming than previously thought
Wildfires produce a witch’s brew of carbon-containing particles. A range of fine carbonaceous particles rising high into the air significantly degrade air quality, damaging human and wildlife health, and interacting with sunlight to affect climate.

Oil-devouring microbe communities a mile deep in the Gulf
The Deepwater Horizon explosion on 20 April 2010, caused the largest marine oil spill in history, with several million barrels of crude oil released into the Gulf of Mexico over the course of three months. Soon after the spill began, a massive oil slick was visible from orbiting satellites, yet once the underwater gusher was sealed, obvious traces of the crude oil disappeared much sooner than nearly all observers predicted. Some of the oil evaporated; some was skimmed off. Microbes “ate” much of the oil as well.

Treating oil spills with chemical dispersants may do more damage than good
Treating oil spills at sea with chemical dispersants is detrimental to European fisheries. Post-spill chemical dispersants may reduce problems for surface animals, but the increased contamination under the water reduces the ability for fish and other organisms to cope with subsequent environmental challenges.

Researchers highlight problem of legacy mercury in the environment
Researchers have published evidence that significant reductions in mercury emissions will be necessary just to stabilize current levels of the toxic element in the environment. So much mercury persists in surface reservoirs (soil, air, and water) from past pollution, going back thousands of years, that it will continue to persist in the ocean and accumulate in fish for decades to centuries, they report.

Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
