NASA -- In the first direct, comprehensive mass survey of the entire Greenland ice sheet, scientists using data from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (Grace) have measured a significant decrease in the mass of the Greenland ice cap. Grace is a satellite mission that measures movement in Earth's mass. In an update to findings published in the journal Geophysical Research Letters, a team led by Dr. Isabella Velicogna of the University of Colorado,...

WEST LAFAYETTE, Ind. -- The quest for a single theory that unites all of the universe's fundamental forces has thus far eluded physicists, but that has not stopped a team of them from clearing the way for nanotechnologists while they look for it. The group, which includes Purdue University's Ephraim Fischbach, has recently completed research that improves our understanding of how tiny objects placed very close together can influence each other. Their experiment, which involves the...

ESA -- A new ESA study predicts that the devastating Sumatran earthquake, which resulted in the tragic tsunami of December 26, 2004, will have left a "Ëœscar' on Earth's gravity that could be detected by a sensitive new satellite, due for launch next year. The Sumatran earthquake measured 9 on the Richter scale and caused widespread devastation and death when it struck unexpectedly late last year. Thankfully, earthquakes of this magnitude are rare events, taking place...
