Biomechanical engineers at the University of Iowa, Iowa City, determined that thigh size in obese people is a reason their hip implants are more likely to fail. In a study, the team simulated hip dislocations as they occur in humans and determined that increased thigh girth creates hip instability in...

Scientists at the Karlsruhe Institute of Technology (KIT) and Ruhr-Universität Bochum (RUB) have reached a record precision in radar distance measurements. With the help of a new radar system, an accuracy of one micrometer was achieved in joint measurements. The system is characterized by...

An ER-2 high-altitude research aircraft operating out of NASA's Wallops Flight Facility in Wallops Island, VA, will take part in the development of two future satellite instruments. The aircraft will fly test models of these instruments at altitudes greater than 60,000 feet to gather information...

A new “traffic light” test devised by Dr. Nick Sheron and colleagues at University of Southampton and Southampton General Hospital in the UK could be used in primary care to diagnose liver fibrosis and cirrhosis in high risk populations more easily than at...

Using the lessons of the Apollo era and robotic missions to Mars, NASA scientists and engineers are working on ways to develop landing pads that could be robotically constructed in advance of future human expeditions to destinations such as the moon or Mars. These specially...

Any parent who’s had to deal with a screaming child with a painful ear infection knows that getting a quick diagnosis and medication if needed is the key to regaining a happy home. What if they were able to skip taking the upset child to the doctor for that diagnosis? That is the question posed by...

NASA’s Mars Science Laboratory Rover Curiosity would have a hard time completing its mission if it were not for a successful partnership between the Jet Propulsion Laboratory and a professor-student team at UT. Ben Blalock, professor of electrical engineering and computer science, and two graduate...

For the first time, an MIT team has managed to create three-dimensional “movies” of electron behavior in a topological insulator, or TI. The movies can capture vanishingly small increments of time — down to the level of a few femtoseconds, or millionths of a billionth of a second — so that...

Army vehicle electronics networking is complex and challenging due to vendor- specific devices and interfaces. Military vehicles require 100% network uptime and security. The network must reduce vehicle clutter, focus on saving soldiers’ lives, and provide minimum latency. Battle requirements...

Warfighter Information Network-Tactical, known as WIN-T, Increment 2, is nearing the finish line having undergone its largest operational test back in May. WIN-T Increment 2 is a major upgrade to the Army's tactical communications backbone and provides an on-the-move network that...

Beginning in October, the U.S. Army will begin fielding the first integrated group of networked technologies – radios, sensors and associated equipment and software – that will for the first time deliver an integrated voice and data capability throughout the entire Brigade...

Many companies, including Raytheon and the Israel-based Argo Medical Technologies, have created self-contained, wearable robotic suits to reduce injuries from heavy lifting, for example, and help paraplegics walk again. Ekso, based in Richmond, California, builds a suit without any...

Researchers at Columbia Engineering have developed new software that can simultaneously calculate the carbon footprints of thousands of products.The team used a life-cycle-analysis (LCA) tool and developed three new techniques that work in concert, enabling them to calculate thousands of footprints within...

They’re fast, powerful, and deafening. Furthermore, military jets need to be up in the air in the wee hours over land to simulate their landings on aircraft carriers. But innovations out of the University of Cincinnati’s Gas Dynamics and Propulsion Laboratory are showing promise in reducing the...

For decades, academic and industry researchers have been working on control algorithms for autonomous helicopters — robotic helicopters that pilot themselves, rather than requiring remote human guidance. Dozens of research teams have competed in a series of autonomous-helicopter challenges posed...

NASA's Hurricane and Severe Storm Sentinel (HS3) mission will be a complex one for the pilots flying NASA's Global Hawk aircraft from the ground. The mission will be the first deployment for the unmanned aircraft away from their regular base of operations at the Dryden Flight...

What if every pregnant woman in the world had access to ultrasound technology to examine the health and development of their unborn child? That’s what engineers at Newcastle University, Newcastle upon Tyne, UK, wondered. They have developed a portable and easy-to-use ultra-low cost scanner that can be...

Millions of injections are given annually, from annual flu shots to childhood immunizations. However, while hypodermic needles deliver controlled, precise injections, the pain they deliver continues to make them unpopular among recipients, especially children. Now, a new laser-based system, being developed by...
