Effortless Sailing with Fluid Flow Cloak

DURHAM, N.C. – Duke engineers have already shown that they can “cloak” light and sound, making objects invisible -- now, they have demonstrated the theoretical ability to significantly increase the efficiency of ships by tricking the surrounding water into staying still. “Ships expend a great deal [...]

Manipulating Light at Will

DURHAM, N.C. – Duke electrical engineers have developed a man-made material that they say literally allows them to manipulate light at will. They say that the results of their latest proof-of-concept experiments could lead to the replacement of electrical components with those based on optical [...]

A Fractal Design Approach to Ease Verification

In 1994, a small glitch was uncovered in a floating point unit in the Pentium P5 microprocessor. Unfortunately, it wasn’t detected until after it had been installed in countless computers, which forced the company to take a $475 million charge to replace the faulty components. Somehow, the defect [...]

WiFi "Napping" Doubles Phone Battery Life

DURHAM, N.C. – A Duke University graduate student has found ways to double the battery life of mobile devices – such as smartphones or laptop computers – by making changes to WiFi technology. Wifi is a popular wireless technology that helps users download information from the Internet. Such [...]

Acoustical Cloaking Achieved

After already showing that simple man-made materials can be employed as invisibility cloaks or used to facilitate wireless power transmission, Duke University engineers have now demonstrated that these same materials can also make objects invisible to sound waves. The engineers designed, built and [...]

New Smartphone App Automatically Tags Photos

DURHAM, N.C. -- So much for tagging photographs with names, locations and activities yourself – a new cell phone application can take care of that for you. The system works by taking advantage of the multiple sensors on a mobile phone, as well as those of other mobile phones in the vicinity. Dubbed [...]

Novel Man-Made Material Could Facilitate Wireless Power

DURHAM, N.C. – Electrical engineers at Duke University have determined that unique man-made materials should theoretically make it possible to improve the power transfer to small devices, such as laptops or cell phones, or ultimately to larger ones, such as cars or elevators, without wires. This [...]

Light on Silicon Better than Copper?

DURHAM, N.C. -- Step aside copper and make way for a better carrier of information -- light. As good as the metal has been in zipping information from one circuit to another on silicon inside computers and other electronic devices, optical signals can carry much more, according to Duke University [...]

DNA Could Be Backbone of Next Generation Logic Chips

DURHAM, N.C. – In a single day, a solitary grad student at a lab bench can produce more simple logic circuits than the world’s entire output of silicon chips in a month. So says a Duke University engineer, who believes that the next generation of these logic circuits at the heart of computers will [...]
