Improving oil recovery, aiding environmental cleanup
Researchers have taken a new look at an old, but seldom-used technique developed by the petroleum industry to recover oil, and learned more about why it works, how it could be improved, and how it might be able to make a comeback not only in oil recovery but also environmental cleanup

New, affordable instant warnings of bridge collapse
The Federal Bureau of Transportation lists nearly 70,000 U.S. bridges as “structurally deficient,” requiring extra surveillance; in addition, more than 77,000 others are categorized as “obsolete” — exceeding their intended lifespan and carrying loads greater than they were designed to handle; researchers developed a new technology for monitoring these 150,000 aging U.S. highway bridges

A second look at off-shore use of vertical-axis wind turbines
Wind energy researchers are re-evaluating vertical axis wind turbines (VAWTs) to help solve some of the problems of generating energy from offshore breezes; though VAWTs have been around since the earliest days of wind energy research, VAWT architecture could transform offshore wind technology

A device used to measure nuclear weapons effects is now used for rocket propulsion system
Can a device formerly used to test nuclear weapons effects find a new life in rocket propulsion research? That is the question in which researchers seek an answer; when assembled, the device will tip the scales at nearly fifty tons, and will be “one of the largest, most powerful pulse power systems in the academic world,” according to one researcher

Researchers say spoofed GPS signals can be countered
From cars to commercial airplanes to military drones, global positioning system (GPS) technology is everywhere — and researchers have known for years that it can be hacked, or as they call it, “spoofed”; the best defense, they say, is to create countermeasures that unscrupulous GPS spoofers can not deceive

Milestone for a Raytheon bomb which acquires, tracks, and then hits moving targets
Raytheon said its Small Diameter Bomb II (SDB II) program achieved a milestone when it successfully engaged and hit a moving target during a flight test at the White Sands Missile Range, New Mexico; the bomb, released from an F-15E, acquired, tracked, and guided to a moving target using its tri-mode seeker, scoring a direct hit

Using dolphins’ signal processing method for sea-mine detection
One way for Iran to close the Straits of Hormuz to shipping is to place thousands of sea mines in the water; research examine how dolphins process their sonar signals, using the findings to provide a new system for man-made sonar to detect targets, such as sea mines, in bubbly water

Cutting massive power use at big data companies in a flash
Big data needs big power; the server farms that undergird the Internet run on a vast tide of electricity — Google, for example, uses enough electricity in its data centers to power about 200,000 homes; now, a team of engineers has a solution that could radically cut that power use — a new type of memory in companies’ servers that demands far less energy than the current systems

New rapid diagnostic test for pathogens, contaminants developed
Using nanoscale materials, researchers have developed a single-step method rapidly and accurately to detect viruses, bacteria, and chemical contaminants; the method could be used to detect pathogens and contaminants in biological mixtures such as food, blood, saliva, and urine

Unmanned systems emulate animals’ conditioned fear-response mechanism for self-preservation
When animals in the wild engage in eating or grazing, their eyes, ears, and sense of smell continuously monitor the environment for any sense of danger; researchers developed a similar conditioned fear-response mechanism for unmanned systems

Using cold plasma to fight fires
Traditional fire-suppression technologies focus largely on disrupting the chemical reactions involved in combustion; from a physics perspective, however, flames are cold plasmas; DARPA, the Pentagon’s research arm, theorized that by using physics techniques rather than combustion chemistry, it might be possible to manipulate and extinguish flames

New sensors detect contaminants in water
Many organic contaminants in the air and in drinking water need to be detected at very low-level concentrations; researchers have investigated the use of graphene oxide films in which the semiconductor titanium dioxide (TiO2) and metal nanoparticles are deposited on opposite sides of the graphene surface

Clay-based coating holds promise of green flame retardants
The thick, fast-forming coating has a uniformly high concentration of flame-inhibiting clay particles, and it adheres strongly to the Swiss cheese-like surface of polyurethane foam, which is used in furniture cushions, carpet padding, children’s car seats, and other items

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.
Falling Space Debris: How High Is the Risk I'll Get Hit?
An International Space Station battery fell back to Earth and, luckily, splashed down harmlessly in the Atlantic. Should we have worried? Space debris reenters our atmosphere every week.
Testing Cutting-Edge Counter-Drone Technology
Drones have many positive applications, bad actors can use them for nefarious purposes. Two recent field demonstrations brought government, academia, and industry together to evaluate innovative counter-unmanned aircraft systems.
Strengthening the Grid’s ‘Backbone’ with Hydropower
Argonne-led studies investigate how hydropower could help add more clean energy to the grid, how it generates value as grids add more renewable energy, and how liner technology can improve hydropower efficiency.
The Tech Apocalypse Panic is Driven by AI Boosters, Military Tacticians, and Movies
From popular films like a War Games or The Terminator to a U.S. State Department-commissioned report on the security risk of weaponized AI, there has been a tremendous amount of hand wringing and nervousness about how so-called artificial intelligence might end up destroying the world. There is one easy way to avoid a lot of this and prevent a self-inflicted doomsday: don’t give computers the capability to launch devastating weapons.
