Researchers at the University of Georgia and Georgia Tech are conducting X-ray research at Brookhaven National Laboratory to reduce iron and other trace metals in paper-making processes. The goal is to lower costs, reduce water use and environmental discharges in the pulp and paper industry.
Researchers at the University of Georgia have discovered an enzyme in Porphyromonas gingivalis that activates blood-clotting in humans, potentially linking periodontal infections to heart disease. The study suggests a mechanism for this connection and may lead to a vaccine to neutralize the enzyme.
A study published by University of Georgia researchers reveals a vast array of novel bacteria in Carolina bays, many of which remain unclassified. The discovery highlights the importance of the microbial world in shaping biodiversity.
Researchers studied chimps' reaction to hand-held mirrors, finding they acted like young children when dressing up. The capacity for playful self-expression appears to exist before it's expressed, suggesting a strong influence of social background on sense of self.
Researchers described the crystal structure of aldehyde dehydrogenase, a vital enzyme involved in animal and plant health. The study provides insights into how the enzyme metabolizes aldehydes, which are highly reactive compounds that can poison cells and trigger cancers.
Dr. Bob Reinert recommends states adopt a single set of guidelines to minimize exposure to contaminants in fish. Effective guidelines can help anglers filter out unwanted chemicals from their catch.
Researchers support a low-temperature origin for carbonate globules in the Martian meteorite ALH84001, suggesting microscopic depositions may be fossilized bacteria. The study uses secondary ion mass spectrometry to analyze oxygen and carbon isotope ratios, indicating a potential formation temperature of less than 300 degrees C.
Agricultural workers in Georgia are now being educated about skin cancer risks through a new program, thanks to $1.15 million in funding from the National Institute of Occupational Safety and Health. The program includes sun block, hats with built-in neck protection, and educational materials targeted at farmers' families.
Researchers have discovered crucial proteins called septins in filamentous fungi, which could serve as a target for antifungal agents. The finding may help develop new treatments for fungal diseases, which have dramatically increased in recent years.
A study by University of Georgia researcher Velma McBride Murry found that African-American women who became mothers as adolescents do not suffer as much as previously thought. In fact, many adolescent mothers reported living above the poverty level and having similar backgrounds to those who remained virgins or had abortions.
Researchers argue that low-temperature formation of mineral deposits supports life on Mars, contradicting recent claims. The Martian meteorite Alan Hills 84001 holds a crucial clue to understanding the planet's potential for past life.
Researchers have discovered a novel phosphorus compound, DIP, in bacteria Thermotoga maritima that thrive at high temperatures, challenging the previous understanding of its role in archaea. The study suggests that DIP may play a role in osmosis and potentially as a thermoprotectant.
A University of Georgia researcher's study found that many PCBs in the environment may not be as carcinogenic as previously believed. The project aimed to re-evaluate the toxicity of PCBs based on new scientific information and changes in cancer classification.
A new study suggests that current methods for measuring nitrogen uptake in oceans are too low, resulting in an estimated 30% underestimation. The finding indicates that newly produced nitrogen may remain suspended as dissolved organic nitrogen, rather than sinking to the ocean floor.
A new study highlights the importance of managing multiple species to prevent extinction, according to Dr. Ron Pulliam, director of the National Biological Service. By identifying vulnerable species and human activities threatening them, conservation efforts can be targeted to save species.
Research by University of Georgia forester Dr. Bob Teskey and colleagues found that managed timber stands can benefit from higher CO2 levels due to improved photosynthesis. The study's results suggest pine trees are better adapted to increased CO2, with positive responses from other species as well.
Researchers at the University of Georgia have developed a new test for detecting DNA strand breakage in freshwater mussels, which can serve as an early warning system for pollution. The study found significant strand breakage in mussels exposed to lead, but no damage after long-term exposure.
Scientists at the University of Georgia have discovered a three-dimensional structure of a fluorescent protein found in jellyfish that resembles a glowing green lantern. This discovery could help make it easier to use the protein as a biomarker for studying gene expression and cell lineage.
Scientists are releasing 15,000 fingerlings into northeast Georgia's Broad River as part of a reintroduction effort for the robust redhorse, a fish thought extinct until survivors were discovered in 1991. The fingerlings have been artificially bred from surviving members and will be released at seven sites to help the species flourish.
A new, potentially serious disease known as White Pox has been discovered on coral reefs near Key West, Florida, causing extensive damage and killing up to 80% of elkhorn coral. The cause of the disease remains unknown, but researchers are studying it to understand its origins and potential impact on the marine ecosystem.
Researchers found that social behavior dictates genetic flow within a single species of social insects, challenging traditional theories. The study discovered four routes of gene flow between single-queen and multiple-queen colonies, highlighting the role of queens in shaping gene exchange.
A team of researchers from the University of Georgia has discovered that plant cells can substitute one sugar for another in their cell walls, a process previously thought to be essential for survival. This finding suggests that oligosaccharins play a role in regulating cell wall growth and development.
