UTA scientists examine global warming events from millions of years ago to gain insight into present-day climate change

A team of scientists led by researchers at The University of Texas at Arlington is examining global warming events that happened millions of years ago in order to gain new insights into present-day climate change. The National Science Foundation’s Division of Ocean Sciences has awarded a $403,114 grant to Arne Winguth, UTA associate professor of earth and environmental sciences, for a three-year study titled “Evaluating Deep-Sea Ventilation and the Global Carbon Cycle during Early Paleogene Hyperthermals.” Winguth is joined on the project by co-investigators Elizabeth Griffith, a UTA

UTA student team wins EPA Campus RainWorks Challenge for concept to reduce stormwater runoff, impacts of climate change

Sustainable environmentA University of Texas at Arlington student team’s design to reduce stormwater runoff that could result from future campus construction projects has won a national Environmental Protection Agency’s Office of Water award as part of the agency’s 2015 Campus RainWorks Challenge. The College of Architecture, Planning and Public Affairs  team included landscape architecture graduate students Baishaki Biswas, Sherry Fabricant, Jacob Schwarz and Ahoura Zandiatashbar, a doctoral student in urban planning and public policy. Their winning entry in

UTA biologists provide first evidence that constant environmental stress causes organisms to program behavioral changes in future generations

Researchers have known for decades that the environmental stress experienced by one generation induces changes in behavior, shape, biochemical properties and rates of development of their offspring. But the precise ecological conditions that produced these responses were not known. Researchers at The University of Texas at Arlington have now provided the first evidence that stable environments like constant predator threats, not unstable conditions, generate these non-genetic “trans-generational responses” in the next generation. “These results have broad implications for

UTA researchers devise more efficient materials for solar fuel cells

University of Texas at Arlington chemists have developed new high-performing materials for cells that harness sunlight to split carbon dioxide and water into useable fuels like methanol and hydrogen gas. These “green fuels” can be used to power cars, home appliances or even to store energy in batteries. “Technologies that simultaneously permit us to remove greenhouse gases like carbon dioxide while harnessing and storing the energy of sunlight as fuel are at the forefront of current research,” said Krishnan Rajeshwar, UTA distinguished professor of chemistry and biochemistry and co-

Researchers provide new details about sea stars' immunity

ARLINGTON, Texas -- A study led by a University of Texas at Arlington graduate student examining sea stars dying along the West Coast provides new clues about the starfish's immune response and its ability to protect a diverse coastal ecosystem. Lauren Fuess, a Ph.D. candidate in quantitative biology, and her team looked at the wasting disease responsible for the largest die-off of sea stars ever recorded. Scientists believe that a virus related to rabies causes wasting disease. When infected, the stars' arms contort, and they develop white lesions. The normally rigid stars begin to melt

Water resources engineer uses advanced sensing, crowdsourcing, other tools to predict urban water flow, hazards and infrastructure needs

Urban Water SustainabilityA UT Arlington water resources engineer has been awarded a four-year, $1.2 million National Science Foundation grant to improve sustainability of large urban areas from extreme weather, urbanization and climate change. D.J. Seo, associate professor of water resources engineering in the Civil Engineering Department , will lead a team of researchers who will integrate data from advanced weather radar systems, innovative wireless sensors and crowdsourcing of data via cell phone applications to create high-resolution modeling of urban water

UT Arlington professor to present climate change research at international gathering

Applying today’s computerized climate models to events millions of years ago could tell scientists about climate change in the Earth’s future, according to University of Texas at Arlington Assistant Professor Arne Winguth. Winguth’s research focuses on a period of climate change and mass extinctions at the boundary of the Permian and Triassic periods, about 251.5 million years ago. At that time, more than 70 percent of species on land and 95 percent of species in the oceans became extinct. Many of the ocean species affected were invertebrates such as the trilobites. On land, early
