Teams from three of the top United States aerospace corporations have spent the last year studying how to meet NASA’s sustainability goals for cleaner, more efficient aircraft. Among the requirements that prompted adventurous design work from the companies was a 50% reduction in fuel consumption and a 75% reduction in harmful emissions.
Most electric motors and generators operate in just one direction. There's no real need for them to go into reverse, but they’ve been designed to work both ways. Dionysios Aliprantis of Iowa State University wants to change that, incrementally chipping away at motor design and optimize performance in just one direction.
Civil engineers at Syracuse University have developed various statistical prediction models using data obtained from the Metropolitan Sewer District of Greater Cincinnati, Ohio, to generate deterioration models for wastewater pipes. The models, when adapted to a given system, is intended to facilitate a proactive approach to pipeline replacements and maintenance.
Manufacturing inspectors usually time procedures manually in order to organize manual assembly operations efficiently. This method is prone to error. A new system invented in Germany records times automatically, helping to costs for companies.
Engineers have discovered details about the behavior of ultrafast laser pulses that may lead to new applications in manufacturing, diagnostics, and other research.
Scientists still aren't sure what causes clogs in flowing macroscopic particles, but new experiments suggest that when particles undergo a force called shear strain, they jam sooner than expected. Nuts, coffee and coal inherently produce this type of movement, but many hoppers and other dispensers aren’t engineered for it.
In the first university-based planetary science experiment at the National Ignition Facility (NIF), researchers have gradually compressed a diamond sample to a record pressure of 50 Mbar (50 million times Earth's atmospheric pressure).
Through the Center for X-Ray Optics, Lawrence Berkeley National Laboratory and leading semiconductor manufacturers have mutually invested in major new facilities at the Advanced Light Source for advanced extreme-ultraviolet lithography, including clean rooms, wafer processing facilities, and microlithography test tools too costly for individual manufacturers.
A weapon prototype developed by the Office of Naval Research (ONR) successfully hit two high-speed boat targets during recent testing. ONR researchers produced the Low-Cost Imaging Terminal Seeker, a suite of low-cost technologies that modify existing helicopter-borne rockets into precision-guided weapons.
It looks like bone. It feels like bone. For the most part, it acts like bone. And it came off an inkjet printer. Washington State University researchers have used a 3D printer to create a bone-like material and structure that can be used in orthopedic procedures, dental work, and to deliver medicine for treating osteoporosis.
As big as a car and as well-equipped as a laboratory, NASA's newest Mars rover blows away its predecessors in size and skill. Powered by plutonium, Curiosity will be lowered to the Martian surface by a jet pack and tether system similar to those used by sky cranes.
Imagine controlling an airplane in flight just by holding your iPhone out in front of you: tilting it in the direction you want the plane to travel, or raising it to make the plane fly higher. Or tapping a point on a map on the screen, and having the plane automatically fly to the designated spot. Now, imagine if the plane itself were a continent away from where you're doing this iPhone-based controlling. What might seem like a figment of the imagination is actually fact.
Since the 1970s, when early autonomous underwater vehicles (AUVs) were developed at the Massachusetts Institute of Technology, scientists there have tackled various barriers to the design of robots that can travel autonomously in the deep ocean. Part two of the four-part series examines how advanced mathematical techniques enable AUVs to survey large, complex, and cluttered seascapes.
A prototype of a new robot face that teams in Germany and Japan have developed ingeniously solves the problem of how to make realistic human features from a variety of angles. A projector accurately beams a human face onto the back of the mask, changing the face on demand.
The Shenzhou 8 craft that was launched by China Tuesday docked today with the already orbiting Tiangong 1 module. The maneuver puts the country closer to manning its own space station, which could occur within the next decade. The U.S. and Russia are the only other countries to master the space docking technique.
Researchers in the U.K. have built a tank-like robot that has the ability to scale smooth walls. It gets its ability from tiny mushroom cap-shaped fibers on its treads that use van der Waals forces to adhere to flat surfaces. Inspired by the feet of geckos, the robot could find use in power plants or search and rescue.
With a muffled "pop," a flash of blue light, and a few ripples through 14,000 gallons of deionized water, Sandia National Laboratories' Annular Core Research Reactor (ACRR) recently conducted its 10,000th operation.
On Tuesday, the auto giant Toyota showcased experimental robots that can help disabled patients work, or even get up out of bed. The company intends to commercialize its walk-assist products sometime after 2013.
The robotics company famous for building BigDog, a four-legged robot that moves in a fashion that is both strange and disturbingly life-like, has added arms to its two-legged variant, PETMAN. A new video from Boston Dynamics shows in the anthromorphic robot in motion.
After some 180 days of running and four hundred trillion proton proton collisions, the Large Hadron Collider's (LHC's) 2011 proton run came to an end at 5:15 p.m., October 30, 2011. For the second year running, the LHC team has largely surpassed its operational objectives, steadily increasing the rate at which the LHC has delivered data to the experiments.
When engineers at the University of California, Berkeley, outfitted a six-legged robotic bug with wings in an effort to improve its mobility, they unexpectedly shed some light on the evolution of flight.
Robots for everyone. That's James McLurkin's dream, and as the director of a Rice University robotics laboratory, he's creating an inexpensive and sophisticated robot called the "R-one" to make the dream a reality.
Oak Ridge National Laboratory has awarded a $13.2 million task order to AREVA Federal Services for fabrication of five drain tanks for the ITER tokamak cooling water system. ITER is an international project to demonstrate the feasibility of commercial fusion energy.
The powerful influence of the Sun and the nature of mysterious dark energy motivate ESA’s next two science missions. Solar Orbiter will venture closer to the Sun than any previous mission, and Euclid will be a space telescope designed to map out the large-scale structure of the cosmos.
With new cutting-edge technology aimed at providing amputees with robotic limbs, a Tel Aviv University researcher has successfully implanted a robotic cerebellum into the skull of a rodent with brain damage, restoring its capacity for movement.
