Groundwater May Have Played Important Role in Shaping Mars

Scientists have been intrigued and puzzled by light-toned layered deposits on Mars since the Mariner spacecraft flybys in the early 1970s. Known as LTDs (Light Toned Deposits), they are Martian sediments that most closely resemble sediments on Earth and are some of the most mysterious features on Mars. Causes for their origin remain unknown, and different mechanisms, including volcanic processes, have been proposed for their formation. But recently data and images from Mars Express suggest that several LTDs were formed when large amounts of groundwater burst on to the surface. Scientists propose that groundwater had a greater role in shaping the Martian surface than previously believed, and may have sheltered primitive life forms as the planet started drying up.

Review: Review of the Cardo S-800 Bluetooth headset

The Cardo S-800 Bluetooth headset definitely has its own look, that much is true. This blocky, two-toned headset actually looks quite nice and modern, and it's incredibly lightweight. The larger backend of the S-800 is silver, while the smaller front portion is clad in a smoky blue color that is pleasing to the eye. The S-800 arrived with an AC power cord, a functional neck strap, and a handy USB charging cable. The neck strap has a special clip on the end that you can attach the S-800 to, but I'd be lying if I told you I used this accessory.
