SACRAMENTO, Calif. — A study on frogs in remote Sierra Nevada mountain habitats including Yosemite National Park and Giant Sequoia National Monument, detected concentrations of pesticides in frog tissue that potentially came from California’s Central Valley sources.

“Our results show that current-use pesticides, particularly fungicides, are accumulating in the bodies of Pacific chorus frogs in the Sierra Nevada,” says Kelly Smalling, a research hydrologist with the U.S. Geological Survey and lead author of the study. “This is the first time we’ve detected many of these compounds, including fungicides, in the Sierra Nevada. The data generated by this study support past research on the potential of pesticides to be transported by wind or rain from the Central Valley to the Sierras.” (more…)

Winter Ski & Ride app for Windows Phone helps you plan ultimate outings, keep track of your friends on the slopes, and beat your personal best.

REDMOND, Wash. – Winter Ski & Ride, a new Windows Phone app in the Nokia Collection, is taking skiing and snowboarding to a new altitude.

Say you’re riding a ski lift to the top of a snow-covered mountain, be it in Colorado, Canada or China. You touch the screen of your Nokia device, with frosty, gloved hands, and pass the lift time by looking at your stats. How many runs have you done? What was your top speed? You look at your contacts, and note what friends are still on the mountain. You decide to ski a mogul-heavy double black diamond run next, and watch a short video by a professional instructor to brush up on your bump skills. (more…)

WASHINGTON – In the first comprehensive global survey of temperature trends in major lakes, researchers have determined that Earth’s largest lakes have warmed during the past 25 years in response to climate change.

Philipp Schneider and Simon Hook of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., used satellite data to measure the surface temperatures of 167 large lakes worldwide.

They reported an average warming rate of 0.45 degrees Celsius (0.81 degrees Fahrenheit) per decade, with some lakes warming as much as 1 degree Celsius (1.8 degrees Fahrenheit) per decade. The warming trend was global, and the greatest increases were in the mid- to high-latitudes of the Northern Hemisphere. (more…)

With the recent advancements in robotics, automation, navigation, and self-driving vehicles, all spurred on by the DARPA Challenge and the research at Georgia Tech among other programs, it’s no surprise to hear that Google has been working very hard on these same kinds of technology.

Sebastian Thrun, Distinguished Software Engineer at Google, recently announced on their blog that so far Google’s efforts to create a self-driving car have been largely successful, though he made it a point to say that the program was still very much in the experimental stages. (more…)
