Gilleaudeau conducting geochemical analysis of carboniferous carbonates & implications for ocean oxygenation
2023-10-30
(Press-News.org)
Geoffrey Gilleaudeau, Assistant Professor, Atmospheric, Oceanic and Earth Sciences (AOES), received funding for the project: "Geochemical Analysis of Carboniferous Carbonates and Implications for Ocean Oxygenation."
He and his collaborators aim to generate a new composite carbon record through the lower Mississippian in the Williston Basin. They also aim to generate a new record that tests the hypothesis that carbon excursion was related to an expansion of global ocean anoxia, or absence of oxygen.
"This project will produce the first complete composition carbon isotope record through the Lower Carboniferous of the Williston Basin, as well as produce a uranium isotope paleo-redox record that tests the influence of ocean anoxia on the initiation of the Late Paleozoic Ice Age," Gilleaudeau said.
Gilleaudeau received $1,100 from the Society for Sedimentary Geology for this research. Funding began in Sept. 2023 and will end in late Dec. 2024.

Scientists have discovered a new species of mosasaur, large, carnivorous aquatic lizards that lived during the late Cretaceous. With “transitional” traits that place it between two well-known mosasaurs, the new species is named after a sea serpent in Norse mythology, Jormungandr, and the small North Dakota city Walhalla near to where the fossil was found. Details describing Jǫrmungandr walhallaensis are published today in the Bulletin of the American Museum of Natural History.

The National Science Foundation (NSF) awarded Emily Burchfield, Emory assistant professor of environmental sciences, $1.6 million to lead efforts to identify emerging pressures on agriculture in Georgia, Iowa and Ohio and to develop predictive models to help farmers and policymakers weather these changes.
“In a nutshell, we’re trying to understand what climate change will mean for agriculture in these three states,” Burchfield says. “We’ll be integrating biophysical projections based on environmental data with insights ...

University of Cincinnati Cancer Center researchers found a seed device that acts as a GPS for surgeons to locate and remove breast and lymph node tumors was safe and effective.
The feasibility study evaluating the use of the devices, called SmartClips, was recently published in the journal The American Surgeon.
UC’s Jaime Lewis and her colleague Elizabeth Shaughnessy helped test the SmartClip devices as they were being developed.
“We went a few times and saw the different prototypes, worked with them, and provided feedback. ...

OKLAHOMA CITY, OKLA. – OU researchers have received a $1.8 million grant from the U.S. Environmental Protection Agency to establish a research center to address children’s cumulative health impacts from agricultural and non-chemical exposures. This grant will create the Children’s Environmental Health Center in the U.S. Southern Great Plains, which includes Oklahoma and Texas. The Center will focus on mitigating the chemical and non-chemical stressors that affect school absenteeism caused by gastrointestinal and respiratory diseases.
This collaborative center will be under the direction of Changjie Cai, Ph.D., assistant professor ...

There is a low-cost way for you to protect yourself and reduce your risk of respiratory diseases such as flu, RSV, and COVID-19. Build yourself a Corsi-Rosenthal box (CR box) in 30 minutes with just $60 worth of common hardware store supplies.
In July, U.S. Environmental Protection Agency scientists began several weeks of advanced bioaerosol chamber testing to assess the efficacy and power of this air filter against infectious aerosols, like the virus that causes COVID-19. The results are in, and they are good.
The U.S. EPA Office of Research and Development’s 3,000 cubic ft. bioaerosol chamber testing results show ...

About The Study: High blood pressure variability indicated increased lifetime dementia risk in late life but not in midlife in this study that included 820 adults monitored for an average time of 32 years. This result suggests that high blood pressure variability may indicate increased dementia risk in older age but might be less viable as a midlife dementia prevention target.

About The Study: In this imaging study that included 54 athletes, higher levels of 18 kDa translocator protein (TSPO) that mark brain injury and repair were found in former National Football League (NFL) players compared with former non-collision sport athletes. The NFL players also had lower performance in learning and memory. These findings suggest that further tracking of TSPO levels in relation to neuropsychological performance over time is needed to understand whether these signs persist, progress, and/or warrant neuroimmune-modulating ...

SAN ANTONIO (Oct. 30, 2023) — About 283 million people worldwide suffer from alcohol use disorder, a debilitating health challenge for which limited therapeutic options are available. The cost to society is estimated at greater than $2 trillion annually.
“People try to rehabilitate, but it is very challenging,” said Yu Shin Kim, PhD, a neuroscience researcher at The University of Texas Health Science Center at San Antonio. “Headache is one of the severe withdrawal symptoms that pushes the rehabilitating patient back to alcohol, because people know that, after drinking, alcohol will actually reduce the headache. It becomes a vicious ...
