On the surface, ants and the Internet don't seem to have much in common. But two Stanford researchers have discovered that a species of harvester ants determine how many foragers to send out of the nest in much the same way that Internet protocols discover how much bandwidth is available for the transfer of data.
Can a computer "read" an online blog and understand it? Several Concordia computer scientists are helping to get closer to that goal. Leila Kosseim, associate professor in Concordia's Faculty of Engineering and Computer Science, and a recently-graduated doctoral student, Shamima Mithun, have developed a system called BlogSum that has potentially vast applications.
A University of Central Florida research team has created the world's shortest laser pulse and in the process may have given scientists a new tool to watch quantum mechanics in action – something that has been hidden from view until now. A photo of Dr. Chang, who accomplished his work at the Florida Atto Science &Technology (FAST) lab in UCF’s Physical Sciences building.
A new "nano machine shop" that shapes nanowires and ultrathin films could represent a future manufacturing method for tiny structures with potentially revolutionary properties. This illustration depicts a new nano machine shop's ability to shape tiny wires, an advance that represents a possible future manufacturing method for applications ranging from high-speed electronics to solar cells.
Today's light-emitting diode light bulbs have a slight environmental edge over compact fluorescent lamps. And that gap is expected to grow significantly as technology and manufacturing methods improve in the next five years, according to a new report from the Department of Energy's Pacific Northwest National Laboratory and UK-based N14 Energy Limited.
Might it one day be possible to transmit electricity from an offshore wind turbine to land-based users without any loss of current? Materials known as "high temperature" superconductors (even though they must be maintained at -140°C!), which can conduct electricity without any losses, were supposed to make this dream a reality.
An interdisciplinary team of researchers at Vanderbilt University have developed a way to combine the photosynthetic protein that converts light into electrochemical energy in spinach with silicon, the material used in solar cells, in a fashion that produces substantially more electrical current than has been reported by previous "biohybrid" solar cells.
Plastic optical fibres, laid on the underlay of a carpet, can bend when anyone treads on it and map, in real-time, their walking patterns. Tiny electronics at the edges act as sensors and relay signals to a computer. These signals can then be analysed to show the image of the footprint and identify gradual changes in walking behaviour or a sudden incident such as a fall or trip.
Stanford electrical engineers overturn existing models to demonstrate the feasibility of a millimeter-sized, wirelessly powered cardiac device A team of engineers at Stanford has demonstrated the feasibility of a super-small, implantable cardiac device that gets its power not from batteries, but from radio waves transmitted from outside the body.
A bad weather front is fast approaching and a cloudburst is imminent. If you happen to be away from home, but have left a window open, either deliberately or because you forgot to check one room, you may be in for a wet surprise when you come home. However, it does not have to be like that: Thanks to a new sensor system, such situations can now be avoided.
For years, professional football players have been forced to lug around hefty playbooks. But the three-ring binders — stuffed with dozens of offensive plays and defensive schemes — are going the way of leather football helmets. The Seattle Seahawks are now converting plays to PDFs and uploading to tablets, with the players using the devices not only to study plays but also to watch video highlights of games and practices.
New Yorkers have long adopted their own techniques in the fine art of hailing a taxicab, a theatrical, frustrating, competitive ritual of the city. There is the high-pitched whistle, the two-handed gesticulation, the rapid snapping of fingers. Many favor the classic wave — an open palm raised high, stretching into coming traffic.
Rogers Corporation will be displaying three of their leading high-performance circuit materials for mobile and fixed-site antennas at the upcoming Mobile Antenna Systems 2012 conference and exhibition. This key event for designers and specifiers of antennas for a wide range of fixed and mobile applications is scheduled for September 18-19, 2012 at the Hyatt Denver Tech Center (Denver, CO).
This is what we talk about when we talk about Disrupt. uBeam , a small startup founded by Meredith Perry , a 22-year-old new graduate from the University of Pennsylvania, has taken on $750,000 in seed funding to build out its technology for wirelessly charging electronic devices. uBeam’s investors include Founders Fund’s angel investing arm , Andreessen Horowitz , Crunchfund , and a number of individual angel investors including Google’s Marissa Mayer and Zappos co-founder Tony Hsieh , uBeam’s Meredith Perry told TechCrunch today in a phone interview.
