2010 Spike in Greenland Ice Loss Lifted Bedrock, GPS Reveals

SAN FRANCISCO – An unusually hot melting season in 2010 accelerated ice loss in southern Greenland by 100 billion tons – and large portions of the island’s bedrock rose an additional quarter of an inch in response.

That’s the finding from a network of nearly 50 GPS stations planted along the Greenland coast to measure the bedrock’s natural response to the ever-diminishing weight of ice above it.

Every year as the Greenland Ice Sheet melts, the rocky coast rises, explained Michael Bevis, Ohio Eminent Scholar in Geodynamics and professor in the School of Earth Sciences at Ohio State University. Some GPS stations around Greenland routinely detect uplift of 15 mm (0.59 inches) or more, year after year. But a temperature spike in 2010 lifted the bedrock a detectably higher amount over a short five-month period – as high as 20 mm (0.79 inches) in some locations. (more…)

A NASA-led research team has confirmed what Walt Disney told us all along: Earth really is a small world, after all.

Since Charles Darwin’s time, scientists have speculated that the solid Earth might be expanding or contracting. That was the prevailing belief, until scientists developed the theory of plate tectonics, which explained the large-scale motions of Earth’s lithosphere, or outermost shell. Even with the acceptance of plate tectonics half a century ago, some Earth and space scientists have continued to speculate on Earth’s possible expansion or contraction on various scientific grounds.

Now a new NASA study, published recently in Geophysical Research Letters, has essentially laid those speculations to rest. Using a cadre of space measurement tools and a new data calculation technique, the team detected no statistically significant expansion of the solid Earth. (more…)

*The first Microsoft Home was built in 1994 to show people how technology could transform everyday experiences, and now years later, the reinvented full-scale model home continues imagine a future in which interacting with computers is as comfortable as coming home.*

REDMOND, Wash. – Aug. 8, 2011 – If there’s no place like home, there’s definitely no place like the Microsoft Home.

There’s a doorbell, but a palm-scan or mobile phone will also open the front door. Sensors let you know your plants need watering. You can check the inventory of your fridge and pantry via your phone while you’re out shopping. Grace, the home’s computer, will even help you check on your grandmother, remember to take your medicine, study up for a big anatomy test, or make focaccia without the need for a recipe book.

“Grace, what’s up?” asks Microsoft Home tour guide Jonathan Cluts once inside the front door. A pleasant-voiced computer responds with updates about appointments, messages, and even information about the weather, traffic and the electric scooter that is charging outside the front door. (more…)
