An optical engineer led the development of the Rapid Adaptive Zoom for Assault Rifles (RAZAR) prototype. At the push of a button, RAZAR can toggle between high and low magnifications, enabling soldiers to zoom in without having to remove their eyes from their targets or their hands from their rifles.
So long, Silicon Valley. These days entrepreneurs and engineers are flocking to a place better...
In the three years since a new standard for gas mileage has been in effect, automakers have...
Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of...
Chemists have devised a way to see the internal structures of electronic waves trapped in carbon nanotubes by external electrostatic charges. However, these traps, or defects, in ultra-thin nanotubes can compromise their effectiveness.
Fewer cords, smaller antennas and quicker video transmission may be the result of a new type of microwave circuit. The research team behind these new circuits currently holds an attention-grabbing world record.
Information and communications technology has already revolutionized industries from publishing and entertainment to education and health care– and now, it’s transportation’s turn. Two easy examples: commuters can access real-time traffic information via their mobile phones, while adaptive signal lights can sense that a car is waiting at a red light with no cross-traffic present and switch to green to accommodate it.
Researchers have discovered a high-tech method of using supercomputers to identify proteins that cause medications to have certain adverse drug reactions, or side effects. They are using high-performance computers to process proteins and drug compounds in an algorithm that produces reliable data outside of a laboratory setting for drug discovery.
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.
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.
Scientists have used computer simulations to show how bacteria are able to destroy antibiotics– a breakthrough that will help develop drugs that can effectively tackle infections in the future. It’s hoped this insight will help scientists to develop new antibiotics with a much lower risk of resistance, and to choose the best medicines for specific outbreaks.
Despite the growing popularity of using computer simulation to help teach college anatomy, students learn much better through the traditional use of human cadavers, according to new research that has implications for health care.
Facebook is launching a tool that lets users notify friends and family that they are safe during or after natural disasters. The tool, called "Safety Check," will be available worldwide to the social network's 1.32 billion users on computers and mobile devices.
Facebook and Apple will now give up to $20,000 in benefits to help employees pay for infertility treatments, sperm donors and even to freeze their eggs. The move comes amid stiff competition for skilled engineers, and as many of the biggest firms try to diversify their male-dominated ranks to include and appeal to more women.
Using 3-D printing and novel semiconductors, researchers have created a power inverter that could make electric vehicles lighter, more powerful and more efficient. At the core of this development is wide band gap material made of silicon carbide with qualities superior to standard semiconductor materials.
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.
A researcher has been studying prosthetics for a decade and is part of a group working to develop a sensor to tell how a limb changes, along with a system that automatically accommodates those changes. After additional testing and refinements, he hopes to find a company that wants to market the sensor system.
Scientists have developed ultra-fast-charging batteries that can be recharged up to 70 percent in only two minutes. The new generation batteries also have a long lifespan of over 20 years, more than 10 times compared to existing lithium-ion batteries.
A plot has been discovered, apparently spread across Russia, India and China, whereby cash machines can be turned into a free money vending machine. The hack requires re-starting the cash machine– essentially a Windows terminal– from a prepared CD that injects malware into the system to circumvent the security.
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.
The familiar “dot-com” and “dot-org” Internet domains hail from the Reagan era, and the trickle of new domains since has usually been met with much discussion and occasionally debate or even discontent. But now, public health officials have brought up a potential concern: the use of the new "dot-health" suffix by groups that aren’t medical experts.
Businesses and governments around the world are increasingly turning to voice biometrics, which sometimes are described as voiceprints, to replace passwords and fight fraud.
Scientists have developed a "smart" lithium-ion battery that gives ample warning before it overheats and bursts into flames. The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones, laptops and other electronic devices, as well as a growing number of cars and airplanes.
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.
On his first visit to Facebook-crazy Indonesia, Mark Zuckerberg met the president-elect, spread the word about his company's global Internet-access initiative and posted a photo of himself at an ancient Buddhist temple.
Scientists have discovered that a common insulating material behaves as a perfect spintronic conductor because it is not affected by background electron charge.
Highlighting unexpected similarities between what animals do and what people are trying to do is a new strategy researchers are using to hopefully increase public awareness about animals and encourage conservation. They’ve created an iPhone app based on biologically inspired design, highlighting two dozen species that have helped engineers solve problems or invent new solutions.
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.
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.
