Researchers Develop New Maritime Target Detection System

SPAWAR Systems Center Pacific has developed RAPIER® full motion video (FMV), a maritime target detection, tracking, and identification solution that quickly and automatically analyzes video, alerts analysts of important targets, and outputs target information.

DOD-funded Technology Lets Muscles Control Prosthetic Hand

After years of intense research and support from Defense Department agencies and a private foundation, a Marine who lost his right hand in Afghanistan is testing new technology that could change everything in the years ahead for someone who loses a limb. The implantable myoelectric sensor system, or IMES, was developed by the California-based Alfred E. Mann Foundation. Now in clinical trials for Food and Drug Administration approval, thanks to 31-year- old Marine Corps Staff Sgt. James Sides, the system lets a patient with sensors, or electrodes, implanted into forearm muscles intuitively control the movements of a prosthetic hand.

Propulsion Technology Could Combat Flight Pollution

A breakthrough propulsion technology to provide greener air transport could be developed after the underlying engineering was declared a success. Six universities and two research organizations from across the EU demonstrated the scientific feasibility of a novel propulsion method that overcomes the main limitations of traditional systems related to jet deflection exhausts.

Mini Models Fire Up to Test Space Launch System

NASA is working with CUBRC Inc. of Buffalo, NY to design, build, and test 2% scale models of the Space Launch System (SLS) propulsion system. Models include two five-segment solid rocket boosters and four core stage RS-25 engines, and a 2% scale model of the entire rocket. The models are fired for short durations of about 50-150 milliseconds per test.

UAVs to Play Critical Role in Precision Agriculture

Researchers are investigating how unmanned aerial vehicles (UAVs) can be used commercially in agriculture. Their size, cost and capabilities make UAVs useful for a wide range of jobs. Mississippi State University researchers are already using these vehicles, and many others are examining their potential applications, including flying a camera on a drone to get instant aerial views of research fields.

A flyover could identify problem spots in extremely large fields, and then researchers, crop consultants, or farmers could go to the identified areas and examine them carefully to make proper diagnoses. The information gathered by soil-moisture sensors could be compared to the information that could be gathered by drones.

Technology already exists to allow producers to make very specific chemical applications to their fields with farm equipment. UAVs can help them target these applications even more precisely.

Smaller Lidars Could Let UAVs Conduct Underwater Scans

Bathymetric lidars – devices that employ powerful lasers to scan beneath the water's surface – are frequently used to map coastal waters. At nearly 600 pounds, the systems are large, heavy, and require costly, piloted aircraft to carry them. But a team at the Georgia Tech Research Institute (GTRI) has designed a new approach that could lead to bathymetric lidars that are much smaller and more efficient than the current full-size systems. The new technology, developed under the Active Electro-Optical Intelligence, Surveillance and Reconnaissance (AEO-ISR) project, would let modest-sized unmanned aerial vehicles (UAVs) carry bathymetric lidars.

New Device Measures How Birds Take Flight

It's quite easy to look at a bird and deduce that it flies by flapping its wings, but understanding exactly how a bird generates lift has long eluded scientists. Now engineers at Stanford have developed a device that precisely and humanely measures the forces generated by a bird's wings while in flight. The work promises to answer many mysteries of bird flight, providing aid in the design of innovative and efficient unmanned aerial vehicles, known as UAVs or, more recently, drones.

MIT Provides Yeast a Different Environment for Ethanol Tolerance

Ethanol and other alcohols can disrupt yeast cell membranes, eventually killing the cells. In research funded by the MIT Energy Initiative and the U.S. Department of Energy, researchers at MIT and the Whitehead Institute for Biomedical Research found that adding potassium and hydroxide ions to the medium in which yeast grow can help cells compensate for that membrane damage.
