AUSTIN, Texas — Scientists from the U.S., U.K. and Australia have used ice-penetrating radar to create the first high-resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried lowland in East Antarctica larger than Texas.

The map reveals some of the largest fjords or ice cut channels on Earth, providing important insights into the history of ice in Antarctica. The data will also help computer modelers improve their simulations of the past and future Antarctic ice sheet and its potential impact on global sea level. (more…)

*New emergency response system helps improve efficiency and deliver better services to citizens*

ARMONK, N.Y., – 02 Jun 2011: IBM today announced it is helping Texas emergency responders in Fort Worth and Tarrant County’s joint emergency operations center (JEOC) better respond to calls for help and communicate instantaneously with dozens of agencies and departments across that state.

Fort Worth and Tarrant County are two of the fastest growing jurisdictions in Texas with about 1.8 million residents. Using social software from IBM and its business partner, UnifiedEdge, the region is rapidly creating a “smarter” and modern public safety system to serve its growing population. (more…)

Northern Mars Landscape Actively Changing

Sand dunes in a vast area of northern Mars long thought to be frozen in time are changing with both sudden and gradual motions, according to research using images from a NASA orbiter.

These dune fields cover an area the size of Texas in a band around the planet at the edge of Mars’ north polar cap. The new findings suggest they are among the most active landscapes on Mars. However, few changes in these dark-toned dunes had been detected before a campaign of repeated imaging by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter, which reached Mars five years ago next month.
