Close to 1,000 earthquakes shook Arizona in 3-year period: study
Historically, most of Arizona has experienced low levels of recorded seismicity, with infrequent moderate and large earthquakes in the state; comprehensive analyses of seismicity within Arizona have not been previously possible due to a lack of seismic stations in most regions, contributing to the perception that widespread earthquakes in Arizona are rare; a new study debunks this myth

Future increases in U.S. natural gas exports may not be as large as thought
Amid policy debate over potential liquefied natural gas (LNG) exports from the United States, a new study predicts the long-term volume of exports from the United States will not likely be very large; the paper also argues that the impact on U.S. domestic natural gas prices will not be large if exports are allowed by the U.S government

New process doubles production, slashes costs of butanol
Butanol has a 30 percent higher energy content than ethanol, lower vapor pressure, and is less volatile, less flammable, and mixes well with gasoline; a new discovery should make butanol more attractive to the biofuel industry

Farmers upset by plan for water banking system
Depending on the depth of the drilling, it can take anywhere from two gallons to two million gallons of water to frack one well; drilling companies consumeenough water in their fracking operations to meet the needs of between 66,400 and 118,000 households; in the parched Midwest, farmers raise questions about water-use priorities

Hurricanes which pass over fresh water can be stronger
About 60 percent of the world’s population resides in areas that are prone to hurricanes or cyclones; researchers find that if a hurricane’s path carries it over large areas of fresh water, it will potentially intensify 50 percent faster than those that do not pass over such regions, meaning it has greater potential to become a stronger storm and be more devastating

Earthquake risks in Europe
How strong can earthquakes in Germany be? Where in Europe are the earthquake activities concentrated? These questions are the basis for risk assessments and become relevant when it comes to the safety of buildings or the generation of tsunami; a new Earthquake Catalogue for Europe and the Mediterranean, which offers details of 45,000 earthquakes during the last millennium, suggests answers to these questions

World’s largest blimp passes flight test
The world’s largest, lighter-than-air, optionally piloted aircraft — the U.S. Army’s Long Endurance Multi-Intelligence Vehicle (LEMV) – completed its first test flight in Lakehurst, New Jersey, the birthplace of the U.S. storied military airship past; the LEMV will provide improved ISR capabilities to the U.S. Army in the form of an “unblinking stare” over ground troops, ranging anywhere from one day to multiple weeks

Advanced explosives detector sniffs out previously undetectable amounts of TNT
TNT and other conventional explosives are the mainstays of terrorist bombs and the anti-personnel mines that kill or injure more than 15,000 people annually in war-torn countries; in large, open-air environments, such as airports, train stations, and minefields, concentrations of these explosives can be as small as a few parts of TNT per trillion parts of air, making it impossible for conventional bomb and mine detectors to detect the explosives and save lives

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.
Tantalizing Method to Study Cyberdeterrence
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
Prototype Self-Service Screening System Unveiled
TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.
