In an ICSI technical report published May 2, Gerald Friedland and Robin Sommer reported that they were able to identify where images posted online were captured. This information is automatically embedded by higher-end digital cameras and smart phones, such as the iPhone. People who post these images are often unaware that they are also posting data about their location.
Friedland and Sommer cross-referenced the latitude and longitude embedded in images with publicly available information, such as Google Maps Street View, to quickly find where photos were taken. The researchers, for example, identified the home addresses of people who put photos on Craigslist, even when those posting the photos had opted to hide their real names and email addresses.
In one search of YouTube videos, the researchers were able to find users with homes near downtown Berkeley by searching the embedded geo-location data. They included the search term “kids” since many home videos are of users’ children. They then searched for videos posted by the same users that had been filmed over 1000 miles away. Within fifteen minutes, the researchers were able to find a resident of Albany, California who was vacationing in the Carribbean, along with a dozen other users who might be vulnerable to burglary.
The results will be presented at the USENIX Workshop on Hot Topics in Security in August. The research has been featured on the ABC News Web site and in New Scientist magazine.Citation:

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
