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.

Report examines use of antibiotics in agriculture

Antibiotics have been used against infectious diseases with great success and have been a part of agriculture for many years. Agricultural uses of antibiotics include the treatment and prevention of diseases in animals and plants and the promotion of growth in food animals. But scientists have long recognized a down side. The concentrated and widespread use of antibiotic agents has resulted in the emergence of drug-resistant organisms, some of which can now survive most commercially available antibio

Study: Acidic surfaces on atmospheric aerosols greatly increase secondary aerosol formation

Atmospheric particles that become acidic through exposure to such pollutants as sulfuric acid can lead to vast increases in the formation of secondary organic aerosols, a new study indicates. Such aerosols are major components of the unsightly haze that hangs over cities and oil refineries and even affects otherwise pristine U.S. national parks.

A report on the research appears in Friday’s (Oct. 25) issue of the journal Science. Authors, all at the University of North Carolina at Chapel
