Magnetorheological fluids set to revolutionise dynamic vehicle suspension systems
Magnetorheological (MR) fluids are smart materials whose flow/viscosity properties can be modified by applying an electric field. These changes in viscosity occur within a fraction of a millisecond – far faster than conventional mechanical means – and can be used to effectively control vibrations in applications dealing with actuation, damping, robotics and mechatronics.
Engineers discover why toucan beaks are models of lightweight strength
As a boy growing up in Brazil 40 years ago, Marc A. Meyers marveled at the lightweight toughness of toucan beaks that he occasionally found on the forest floor. Now a materials scientist and professor of mechanical and aerospace engineering at UCSD's Jacobs School of Engineering, Meyers said makers of airplanes and automobiles may benefit from the first ever detailed engineering analysis of toucan beaks conducted in his lab.
'Long' distances measured with picometer accuracy
A new laser-based method for measuring millimeter distances more accurately than ever before--with an uncertainty of 10 picometers (trillionths of a meter)--has been developed and demonstrated by a physicist at the National Institute of Standards and Technology (NIST).
Optical vortex could look directly at extrasolar planets
A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. It would do this by "nulling" out the light of the parent star by exploiting its wave nature, leaving the reflected light from the nearby planet to be observed in space-based detectors.
Better body armor expected from new materials process
A Georgia Institute of Technology researcher has developed a process that increases the hardness and improves the ballistic performance of the material used by the U.S. military for body armor. The researcher's start-up company is commercializing the technology.
Engineers study corrosion-resistant material for bridges
Civil engineers at Purdue University are developing a new generation of bridges that will contain corrosion-resistant plastic bars reinforced with glass or carbon fibers, promising to double the number of years between expensive repairs.
New nanosensor uses quantum dots to detect DNA
Using tiny semiconductor crystals, biological probes and a laser, Johns Hopkins University engineers have developed a new method of finding specific sequences of DNA by making them light up beneath a microscope.
Researchers find way to reduce power consumption of transistors in computer chips
University of Kentucky researchers have discovered a means of reducing gate leakage current of transistors in computer chips that will permit chip producers to continue developing more efficient and powerful chips with reduced power consumption.
Breakthrough chip delivers better digital pictures for less power
The next advance in cameras is becoming a reality at the University of Rochester. Imaging chips revolutionized the photography industry, and now the chips themselves are being revolutionized. A pair of newly patented technologies may soon enable power-hungry imaging chips to use just a fraction of the energy used today and capture better images to boot—all while enabling cameras to shrink to the size of a shirt button and run for years on a single battery.
Growing the next generation of water recycling plants
A vegetated rooftop recycling system has been developed that allows water to be used twice before it is flushed into the communal waste water system.

Electronic walls, ceilings make it easy to change lightning, room design
The Alliance for Solid-State Illumination Systems and Technologies (ASSIST), an LED industry group organized by the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, unveiled a novel concept for lighting homes and offices. The design integrates light-emitting diode (LED) technology with building materials and systems to create electronic walls and ceilings.
New manufacturing process helps metals lose weight
A pioneering manufacturing process that can turn titanium, stainless steel and many other metals into a new breed of engineering components could have a big impact across industry.
A FASTT first from the ONR
Before the sun had even risen over Wallops Island, Va., on 10 December 2005, a joint Office of Naval Research/Defense Advanced Research Projects Agency vehicle achieved a world first. At an altitude of 63,000 feet, the Freeflight Atmospheric Scramjet Test Technique (FASTT) vehicle became the first air-breathing, liquid hydrocarbon fuel-powered scramjet engine to fly.
DNA self-assembly used to mass-produce patterned nanostructres
Duke University scientists have used the self-assembling properties of DNA to mass-produce nanometer-scale structures in the shape of a 4x4 grids, on which patterns of molecules can be specified. They said the achievement represents a step toward mass-producing electronic or optical circuits at a scale 10 times smaller than the smallest circuits now being manufactured.
Stretchable silicon could be next wave in electronics
The next wave in electronics could be wavy electronics. Researchers at the University of Illinois at Urbana-Champaign have developed a fully stretchable form of single-crystal silicon with micron-sized, wave-like geometries that can be used to build high-performance electronic devices on rubber substrates.
Engineers offer long-term relief for heating and cooling costs
As winter marches on, and with energy resources in question after a disastrous hurricane season, American homeowners are opening their energy bills with trepidation, and heating and cooling system manufacturers are seeking ways to offer them relief.
Experts urge action to protect Istambul from earthquake
A major earthquake is likely to strike Istanbul over the next 30 years, killing thousands of people and collapsing as many as 50,000 buildings because of vulnerable construction, according to a team of engineers and scientists who recommend immediate action to protect the city.
Study of nanoscale gold could led to optical chips
Researchers at the U.S. Department of Energy's Argonne National Laboratory have found that gold "shines" in a different way at the nanoscale, and the insights may lead to new optical chips for computers or for switches and routers in fiber networks.
Ames Lab alloy could boost next generation jet fighter
The next generation of jet fighter aircraft could fly farther and faster thanks to a new high-strength aluminum alloy prepared at the U.S. Department of Energy's Ames Laboratory. The new alloy is one material being developed for use in the F-35 Joint Strike Fighter, a cutting-edge aircraft that will see widespread use as the primary fighter for the U.S. Navy, Air Force, and Marines as well as U.S. allies abroad.
Electronic nose could spell the end of landfill pongs
Scientists at the University of Manchester have invented a new device which remotely monitors bad odours and methane gases at waste landfill and water treatment sites.
