At first glance, the static, greyscale display created by a group of researchers might not catch the eye of a thoughtful consumer in a market saturated with flashy, colorful electronics. But a closer look at the specs could change that: the ultra-thin LCD screen is capable of holding three-dimensional images without a power source, making it a compact, energy-efficient way to display visual information.
An optical engineer led the development of the Rapid Adaptive Zoom for Assault Rifles (RAZAR)...
Fewer cords, smaller antennas and quicker video transmission may be the result of a new type of...
Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky. A researcher says that, because of a highly abnormal and extended lack of solar activity, the solar wind is exhibiting extremely low densities and magnetic field strengths, which causes dangerous levels of hazardous radiation.
DNA has garnered attention for its potential as a programmable material platform that could spawn entire new and revolutionary nanodevices in computer science, microscopy, biology and more. Now scientists have designed the first large DNA crystals with precisely prescribed depths and complex 3D features, which could create revolutionary devices.
Engineers have built and tested an earthquake-resistant house that stayed staunchly upright even as it shook at three times the intensity of the destructive 1989 Loma Prieta temblor 25 years ago.
The daily trimming of fingernails and toenails to make them more aesthetically pleasing could be detrimental and potentially lead to serious nail conditions. This is according to researchers who have devised equations to identify the physical laws that govern nail growth, and used them to throw light on the causes of some of the most common nail problems, such as ingrown toe nails, spoon-shaped nails and pincer nails.
Why is the Sun's million-degree corona, or outermost atmosphere, so much hotter than the Sun's surface? This question has baffled astronomers for decades. Now, a team has found that miniature solar flares called nanoflares— and the speedy electrons they produce— might partly be the source of that heat, at least in some of the hottest parts of the Sun's corona.
To help laser systems overcome loss, operators often pump the system with an overabundance of photons, or light packets, to achieve optical gain. But now, engineers have shown a new way to reverse or eliminate such loss by, ironically, adding loss to a laser system to actually reap energy gains. In other words, they’ve invented a way to win by losing.
Researchers have designed a family of materials to make LEDs that don’t include rare earths but instead are made out of copper iodide, which is an abundant compound. They tuned them to glow a warm white shade or various other colors using a low-cost solution process.
Electronics based on carbon, especially carbon nanotubes, are emerging as successors to silicon for making semiconductor materials. They may enable a new generation of brighter, low-power, low-cost lighting devices that could challenge the dominance of LEDs in the future and help meet society's ever-escalating demand for greener bulbs.
Developing a cloak of invisibility would be wonderful, but sometimes simply making an object appear to be something else will do the trick, according to electrical engineers. They have developed a metamaterial coating with a negligible thickness that allows coated objects to function normally while appearing as something other than what they really are, or even completely disappearing.
Inexpensive microrobots capable of probing and manipulating individual cells and tissue for biological research and medical applications are closer to reality with the design of a system that senses the minute forces exerted by a robot's tiny probe.
Chemists have synthesized a ferromagnetic superconducting compound that is amenable to chemical modification, opening the route to detailed studies of this rare combination of physical properties.
A new study looked for which "tunable" variables were most influential in depicting various cloud types in a global atmospheric model. They found that different parameters influenced different types of clouds.
Two research teams working in the same laboratories at a university have found distinct solutions to a critical challenge that has held back the realization of super powerful quantum computers.
Scientists have discovered that a common insulating material behaves as a perfect spintronic conductor because it is not affected by background electron charge.
A surprising phenomenon has been found in metal nanoparticles: they appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal configuration.
The discovery of a new particle will help provide greater understanding of a strong interaction, the fundamental force of nature found within the protons of an atom's nucleus.
A new measurement of dark matter in the Milky Way has revealed there is half as much of the mysterious substance as previously thought. Astronomers used a method developed almost 100 years ago to discover that the weight of dark matter in our own galaxy is 800,000,000,000 times the mass of the Sun.
A new method for transferring energy from organic to inorganic semiconductors could boost the efficiency of widely used inorganic solar cells. Researchers have developed a new method for harvesting the energy carried by particles known as dark spin-triplet excitons with close to 100 percent efficiency, clearing the way for hybrid solar cells that could far surpass current efficiency limits.
More than 2.8 megaliters of water has been saved in just under a year using groundwater to cool the Pawsey Centre supercomputer. To make that happen, scientists have undertaken stringent tests to ensure that returning heated water to the Mullalloo aquifer has no adverse effects.
Welding isn't just for aircraft carriers anymore. The U.S. Navy could be turning to ultrasonic welding to make its uniforms lighter, stronger and cheaper. And if the project by a Rhode Island company and the Navy Clothing and Textile Research Facility is a success, it could help bring manufacturing back from overseas.
A team of English researchers recently returned from Iceland where, thanks to a bit of luck, they gathered the most extensive dataset ever from a volcanic eruption, which will likely yield considerable new insights into how molten rock moves underground, and whether or not a volcano will erupt.
Whether on baby bottles, beer mugs or perfume bottles, imprints on glass consist mainly of lead oxide. Now, researchers have developed printing inks for glass that do not contain any toxic elements.
It’s a well-known phenomenon in electronics: shining light on a semiconductor, such as the silicon used in computer chips and solar cells, will make it more conductive. Now, researchers have discovered that, in a special semiconductor, light can have the opposite effect, making the material less conductive instead.
Researchers have developed a new way of creating surfaces on which droplets of any desired shape can spontaneously form. They say this approach could lead to new biomedical assay devices and LED display screens, among other applications.
Isamu Akasaki and Hiroshi Amano of Japan and U.S. scientist Shuji Nakamura won the Nobel Prize in physics today for the invention of blue light-emitting diodes, a breakthrough that spurred the development of LED technology used to light up computer screens and modern smartphones.
