Better 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.

Highly sensitive polymer detects IEDs
A chemical which is often the key ingredient in improvised explosive devices (IEDs) can be quickly and safely detected in trace amounts by a new polymer created by a team of Cornell University chemists. The polymer, which potentially could be used in low-cost, handheld explosive detectors and could supplement or replace bomb-sniffing dogs.

Protecting and climate proofing Europe’s coast
The coastline of EU member states extends over 17,000 kilometers. It is home to seventy million inhabitants. The estimated value of the assets within 500 meters from the coast rises to a staggering 1,000 billion Euros. An EU-funded science and engineering initiative is gathering all relevant scientific knowledge to develop a systematic approach to deliver a safe, natural, and climate-proof European coast.

Laser-driven neutrons to detect nuclear smuggling
Researchers have successfully demonstrated for the first time that laser-generated neutrons can be enlisted as a useful tool in the war on terror, as Los Alamos shows first nuclear material detection by single short-pulse-laser-driven neutron source.

Students control a helicopter in flight using only brain waves
A remote controlled helicopter has been flown through a series of hoops around a college gymnasium in Minnesota. It sounds like your everyday student project; but there is one caveat: the helicopter was controlled using just the power of thought. The helicopter was controlled by a noninvasive technique called electroencephalography (EEG), which recorded the electrical activity of the students’ brains through a cap fitted with sixty-four electrodes.

U.S. unlikely to meet its biofuel goals
The Energy Independence and Security Act of 2007 (EISA) mandates that by 2022 the United States derive fifteen billion gallons per year of ethanol from corn to blend with conventional motor fuels. A new study says that if the climate continues to evolve as predicted by the Intergovernmental Panel on Climate Change, the United States stands little to no chance of satisfying its biofuel goals.

Science Academies highlight role of science in meeting global challenges
Science academies from around the globe issued joint statements last week to call world leaders’ attention to the role science, technology, and innovation can play in the pursuit of sustainable development, and to raise their awareness of the emerging threat of drug resistance in infectious agents including tuberculosis. The “G-Science” statements are intended to inform government leaders attending next month’s G8 Summit and other international gatherings later this year.

California Democratic lawmakers want a go-slow approach to fracking
California may be on the verge of an oil rush. It is estimated that hydraulic fracturing, or fracking, at the Monterey Shale formation may tap reserves of fifteen billion barrels of oil. Democratic lawmakers do not see it that way, and have proposed numerous anti-fracking bills aiming to control the use of the controversial technology. Ten bills have been tabled so far, and more are on the way.

Laser weapons on ships require reliable shipboard power
For the first time, a laser weapon system (LaWS) will be placed onboard a deployed ship, USS Ponce, for testing in the Persian Gulf in 2014. The U.S. Navy’s plan to put laser weapons on ships, makes the need for reliable, high-voltage shipboard power a matter of national security.

Smartphone technology to accelerate development of unattended sensors
DARPA wants to develop low-cost, rapidly updatable intelligence, surveillance, and reconnaissance (ISR) sensors – to be used by the military on the ground, in the air, at sea, and undersea – in less than a year, a marked improvement to the current three-to-eight year development process. It hopes to do so by using an original design manufacturer (ODM) process similar to that of the commercial smartphone industry.

Sandia Lab hosting conversations on engineering
U.S. prosperity depends on effective use of engineering to turn scientific innovation into products that come rapidly to market and increasingly are made in the United States. Sandia Lab has launched a series of conversations a aimed to help identify what the nation’s engineering community can do to make sure technical talent will be available in the future, prepare engineers for the twenty-first century, and secure U.S. leadership in a global economy which is increasingly focused on innovation.

As wildfires increase, scientists call for more study of terrestrial, atmospheric effects
Wildfire is a disturbance of ecosystems, and concerns continue to grow about the terrestrial and atmospheric effects of wildfires. Wildfires are expected to increase 50 percent across the United States under a changing climate, over 100 percent in areas of the West by 2050 as projected by some studies.

New filtration material to make petroleum refining cheaper, more efficient
A newly synthesized material might provide a dramatically improved method for separating the highest-octane components of gasoline. The material is a metal-organic framework, or MOF, which can be imagined as a sponge with microscopic holes.

Smartphone turned into handheld biosensor
Scientists and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones. Researchers have developed a cradle and app for the iPhone that uses the phone’s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses, and other molecules.

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.
