UDaily: Liquid calcium carbonate - Geologist Adam Wallace reports in 'Science' that calcium carbonate has a dense liquid phase
08/23/2013 -

Computer simulations could help scientists make sense of a recently observed and puzzling wrinkle in one of nature’s most important chemical processes. It turns out that calcium carbonate — the ubiquitous compound that is a major component of seashells, limestone, concrete, antacids and other naturally and industrially produced substances — may momentarily exist in liquid form as it crystallizes from solution. 

“Our simulations suggest the existence of a dense liquid form of calcium carbonate,” said co-corresponding author Adam Wallace, an assistant professor of geological sciences in UD’s College of Earth, Ocean, and Environment who conducted the research while a postdoctoral researcher at the Lawrence Berkeley National Laboratory. “This is important because it is an as-yet unappreciated component of the carbon cycle.”

UDaily: Morphing manganese - UD researchers report new discovery in 'Science' about manganese in aquatic environments
08/23/2013 -

An often-overlooked form of manganese, an element critical to many life processes, is far more prevalent in ocean environments than previously known, according to a study led by University of Delaware researchers that was published this week in Science.

The discovery alters understanding of the chemistry that moves manganese and other elements, like oxygen and carbon, through the natural world. Manganese is an essential nutrient for most organisms and helps plants produce oxygen during photosynthesis.

Debate over the Delaware City refinery revealed problems with the state’s Coastal Zone Act, but there’s little chance of changes to the landmark conservation law despite complaints from supporters and critics alike who agree that it’s flawed.

Delaware enacted the law in 1971 to block attempts to build a second refinery along the lower Delaware River, a move certain to bring in other new heavy industries. The measure banned all new heavy industries from a 275,000 acre buffer along the river, Delaware Bay, Atlantic Coast and Chesapeake & Delaware Canal, but regulations to manage the law were not approved until the late 1990s and remain incomplete.

UDaily: Environmental chairs - Three faculty members named Unidel environmental chairs
08/15/2013 -

Three University of Delaware faculty members have been appointed to new chairs for environmental research through the generous support of the Unidel Foundation. Kent Messer has been named the Unidel Howard Cosgrove Chair for the Environment, Holly Michael has been named the Unidel Fraser Russell Chair for the Environment, and Adam Rome has been named the Unidel Helen Gouldner Chair for the Environment. 

Interim Provost Nancy Brickhouse announced the positions, all of which are five-year career development chairs, today. The positions are effective Sept. 1.

UDaily: Breathing of the forest - UD undergraduates examining forests' roles in managing carbon and acid rain
08/03/2013 -

Traversing through the woods can be quite an adventure, especially when your adventuring includes high-tech scientific equipment. 

That’s exactly what three University of Delaware students, environmental science majors Katie Junghenn and Alexey Shiklomanov from the College of Earth, Ocean, and Environment and environmental engineering major Kelsey McWilliams of the College of Engineering, are finding this summer. The trio is conducting field research at the Fair Hill (Md.) Natural Resource Management Area to help improve understanding of how forests cycle carbon through the environment and how certain species of trees interact with acid rain.

UDaily: EPSCoR Track-2 - New grant from NSF EPSCoR will establish water resources network
07/24/2013 -

The Delaware Experimental Program to Stimulate Competitive Research (EPSCoR) is a partner in a three-year, $6-million grant from the National Science Foundation through its EPSCoR Research Infrastructure Improvement Track-2 program.

The grant program supports research by consortia of EPSCoR jurisdictions. Through this award, Delaware will join with the EPSCoR programs in Rhode Island and Vermont to form the North East Water Resources Network (NEWRnet). Two million dollars of the grant will go to each of the three states involved.

UDaily: Island journey - UD students travel to Palau for scientific cruise, marine policy discussions
07/10/2013 -

In the small island nation of Palau, located 600 miles east of the Philippines, rising sea levels threaten infrastructure and the economy — but there are very limited resources to address such problems.

Marisa Van Hoeven, a master’s degree student in marine policy in the University of Delaware’s School of Marine Science and Policy in the College of Earth, Ocean, and Environment (CEOE), traveled to the remote country last week to discuss climate adaptation with government officials. 

UDaily: Through July 30: MacArtor exhibit,  Library exhibits 'In Memoriam: June D. MacArtor Environmental Guardian'
07/09/2013 -

The University of Delaware Library has announced a one-case memorial exhibition saluting the legacy of environmental protection championed by the late June D. MacArtor (June 3, 1930-June 13, 2013).

The exhibition, titled “In Memoriam: June D. MacArtor, Esquire, Delaware’s Environmental Guardian,” will be on display in the Information Room of Morris Library through Tuesday, July 30.

UDaily: Algae species holds potential for dual role as pollution reducer, biofuel source
06/27/2013 -

A hardy algae species is showing promise in both reducing power plant pollution and making biofuel, based on new research at the University of Delaware. The microscopic algae Heterosigma akashiwo grows rapidly on a gas mixture that has the same carbon dioxide and nitric oxide content as emissions released from a power plant.

It's the first day of summer, a hot time in the desert city of Phoenix. And in cities across the United States--and the Northern Hemisphere. Heat islands, as these urban hot spots are called, are metropolitan areas significantly warmer than surrounding rural areas. Why?
