Earth's mantle affects long-term sea-level rise estimates

New findings reveal that the U.S. shoreline -- from Virginia to Florida -- has been uplifted by more than 210 feet, meaning less ice melted than expected. This is big news for scientists who use the coastline to predict future sea-level rise.

Bacterium from Canadian high Arctic offers clues to possible life on Mars

The recent discovery of a bacterium that is able to thrive at minus 15 degrees Celsius, the coldest temperature ever reported for bacterial growth, is exciting because it offers clues about some of the necessary preconditions for microbial life on Mars.

NASA ships sensors for seafaring satellite to France

Three NASA-built instruments that are integral components of the next in a series of U.S./European ocean altimetry satellites have arrived in France for integration with their spacecraft in preparation for a 2015 launch. Jason-3 will extend the two-decade series of satellites that are tracking global sea level changes and enabling more accurate weather, ocean and climate forecasts.
