Colorado U. space team studying water, ice and potential life on Jupiter moon, Europa

The oozing of glacial material in the floating ice shell on Jupiter’s moon Europa has important implications for future exploration of the enigmatic moon and prospects of life in its ice-covered ocean, according to a University of Colorado at Boulder professor.

Robert Pappalardo, an assistant professor in the astrophysical and planetary sciences department and one of the world’s foremost Europa experts, said the icy moon is believed to contain an ocean some 13 miles under its icy

Increasingly salty Mediterranean favors ice sheet growth

About 150,000 years ago, an anomalous ice age was triggered by an increasingly salty Mediterranean Sea, a development that’s occurring today and may start new ice sheet growth in the next few decades, according to a study at the University of Minnesota. Robert Johnson, an adjunct professor of geology and geophysics, will present his study of the glaciation 150,000 years ago and discuss its implications for today’s climate on Tuesday, Oct. 29, at the annual meeting of the Geological Society

Brazilian shellfish may improve understanding of ancient world

Brachiopods, the most common shellfish in Paleozoic times, now live primarily in the chilly waters of northern fjords and the Antarctic shelf, except for an abundant population in the tropic waters of the continental shelf off southeast Brazil.

The Brazilian brachiopods are the best modern analogy for the life and times of the critter that was so pervasive over 250 million years ago, says David Rodland, Ph.D. student in geological sciences at Virginia Tech. He has been studying the p

Land subsidence measurements may improve groundwater management

Geological sciences researchers at Virginia Tech are using GPS antennas to measure aquifer use and storage capacity. At the Geological Society of America’s 114th annual meeting in Denver, Oct. 27-30, master’s degree student Sandra Warner will make the case for the broader coverage of such tools.

Warner and Virginia Tech geological sciences professor Thomas Burbey are conducting a large-scale aquifer test on a new municipal well in the Virgin River Valley near Mesquite, Nev. In add

Is being big clam on the block a factor in species success?

Body size is one of the most important biological characteristics in the study of organisms, telling a researcher a lot about how a particular animal lives and interacts with it’s environment and with other species. Despite this importance, there has been little study of body size trends of ancient life.

Now, using marine life forms as models, three Virginia Tech doctoral students in geological sciences have launched a long-term research project to see what can be learned about life ac

Calcium-blocker drug slows artery clogging better than beta blocker

High blood pressure treatment with a calcium channel antagonist slowed progression of atherosclerosis, the disease process responsible for heart attacks and strokes, better than a beta blocker, according to a rapid track report posted online this week in Circulation: Journal of the American Heart Association.

Rapid track articles are released online early because Circulation editors believe the work has major clinical impact or represents important basic science discoveries.
