Some Dating Websites Do Not Remove GPS Data From Photos, CU-Boulder Students Find

While the majority of dating websites do a good job of managing the privacy of their users, a class research project at the University of Colorado Boulder’s Leeds School of Business found that 21 of 90 dating websites the class examined did not properly remove location data from pictures uploaded by their users.

As a result of people taking more photographs with cameras and cell phones containing Global Positioning System chips, some dating website profile pictures contain GPS coordinates showing where a picture was taken, said Associate Professor Kai Larsen, who taught the class on Privacy in the Age of Facebook. When such information is not removed by the dating website, commonly available tools can be used to detect the location of a person’s residence or other locations frequented by the user. (more…)

Some Earthquakes Expected Along Rio Grande Rift in Colorado And New Mexico, New Study Says

The Rio Grande Rift, a thinning and stretching of Earth’s surface that extends from Colorado’s central Rocky Mountains to Mexico, is not dead but geologically alive and active, according to a new study involving scientists from the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences.

“We don’t expect to see a lot of earthquakes, or big ones, but we will have some earthquakes,” said CU-Boulder geological sciences Professor Anne Sheehan, also a fellow at CIRES. The study also involved collaborators from the University of New Mexico, New Mexico Tech, Utah State University and the Boulder-headquartered UNAVCO. The Rio Grande Rift follows the path of the Rio Grande River from central Colorado roughly to El Paso before turning southeast toward the Gulf of Mexico. (more…)

MU Engineers Developing Military Applications for Smartphones

COLUMBIA, Mo. – Tracking military targets? The University of Missouri’s College of Engineering has an app for that.

Engineers from the MU College of Engineering, with funding from the U.S. Army/Leonard Wood Institute, have enhanced popular smartphones to be able to find and track targets. In addition, the engineers have developed ad hoc networks so that soldiers can relay smartphone information without using the internet. (more…)

Evidence Emerges of Ancient Lake in California’s Eel River

*Ecological changes from lakebed may have led to two different populations of once-related steelhead trout*

A catastrophic landslide 22,500 years ago dammed the upper reaches of northern California’s Eel River, forming a 30-mile-long lake which has since disappeared. It left a living legacy found today in the genes of the region’s steelhead trout.

Using remote-sensing technology known as airborne Light Detection and Ranging (LiDAR) and hand-held global-positioning-systems (GPS) units, scientists recently found evidence for a late Pleistocene, landslide-dammed lake along the river. (more…)

VIENNNA, Austria – At the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) meeting, American researchers are unveiling a new tool for detecting illegal nuclear explosions: the Earth’s global positioning system (GPS).

Even underground nuclear tests leave their mark on the part of the upper atmosphere known as the ionosphere, the researchers discovered, when they examined GPS data recorded the same day as a North Korean nuclear test in 2009. Within minutes on that day, GPS stations in nearby countries registered a change in ionospheric electron density, as a bubble of disturbed particles spread out from the test site and across the planet.

*Windows Phone “Mango” connects smartphone users to people, apps and the Internet faster and easier.*

REDMOND, Wash. – May 24, 2011 – Microsoft today provided the first official look at the next release of Windows Phone, code named “Mango.” The new release includes hundreds of new features that will deliver smarter and easier communications, apps and Internet experiences.

“When we looked ahead to the next release, we wanted to stay true to the principles of Windows Phone 7 – that software should get out of your way and quickly connect you to the things that matter most,” said Greg Sullivan, senior product manager of mobile communications at Microsoft. “Mango builds on the work that we did in Windows Phone 7 and extends a lot of key scenarios around communications, apps, and Internet experiences – with even more capability and a deeper level of integration.” (more…)

COLUMBIA, Mo. — During the past 60 years, humans have built rockets, walked on the moon and explored the outer reaches of space with probes and telescopes. During these trips in space, research has been conducted to learn more about life and space. Recently, a group of prominent researchers from across the country published a report through the National Academy of Sciences that is intended as a guide as NASA plans the next 10 years of research in space. Rob Duncan, the University of Missouri Vice Chancellor for Research, led the team that developed a blueprint for fundamental physics research in space for the next 10 years. (more…)

GPS Not Working? A Shoe Radar May Help You Find Your Way

The prevalence of global positioning system (GPS) devices in everything from cars to cell phones has almost made getting lost a thing of the past. But what do you do when your GPS isn’t working? Researchers from North Carolina State University and Carnegie Mellon University (CMU) have developed a shoe-embedded radar system that may help you find your way.

“There are situations where GPS is unavailable, such as when you’re in a building, underground or in places where a satellite connection can be blocked by tall buildings or other objects,” says Dr. Dan Stancil, co-author of a paper describing the research and professor and head of NC State’s Department of Electrical and Computer Engineering. “So what do you do without satellites?” (more…)
