Scientists have found that the largest source of iron in the North Atlantic comes from dust blowing in from the Sahara desert, but other sources such as sediments also play a significant role. This discovery has important implications for understanding the carbon cycle and past climate change.
Researchers bridge the size gap to study kinetic behavior of Ag nanocatalysts using SERS, providing real-time reaction information. The stepped surface of etched nanoparticles mimics sub-5-nm environment, increasing active surface atoms' participation in catalysis.
Researchers at the University of South Carolina have discovered a novel pathway for marijuana to suppress immune functions, suggesting its potential in treating autoimmune diseases. The study found that THC can change histone molecules leading to inflammation suppression.
A new study by University of South Carolina anthropologist Sharon DeWitte provides insights into how the plague shaped population demographics and health for generations. The findings suggest that survivors of the Black Death experienced improvements in health and longevity, with many people living to ages of 70 or 80 years.
A new study found that post-traumatic stress disorder (PTSD) patients have altered microRNA expression linked to chronic inflammation. The study suggests trauma may cause changes in microRNA, promoting inflammation and contributing to secondary medical conditions.
Researchers at University of South Carolina develop a new method to restore antibiotics' power, using protective polymers to combat bacterial defenses. The approach has shown promise in lab tests, particularly against hospital-associated strains of MRSA.
Research finds radiation contamination hinders plant matter decomposition, leading to dry detritus buildup and increased wildfire hazard. Slower decomposition also reduces nutrient supply for plants, affecting tree growth near the Chernobyl site.
Researchers have developed an ultrasensitive nanoprobe that can detect just four circulating tumor cells in the bloodstream, surpassing traditional enzyme-based methods. This breakthrough system uses Fe3O4 nanoparticles to electrochemically sense cancer cells and offers a robust solution for early cancer detection.
A new study found that counties where Wal-Mart built stores experienced a less significant drop in crime rates compared to other counties. The study, which analyzed data from over 3,000 US counties, suggests that the retailer's presence may even contribute to higher crime rates in areas with existing social issues.
A new study finds that nearly half of black males and almost 40 percent of white males are arrested by age 23, affecting their ability to find work, attend school, and fully participate in their communities. The study also reveals little race variation in arrest rates among females.
A study by the University of South Carolina's Arnold School of Public Health found that US mothers are less physically active than previous decades, spending more time watching TV than cooking, cleaning, and exercising. This decline in physical activity has led to a decrease in energy expenditure, potentially predisposing children to o...
Researchers at University of South Carolina discover THC influences microRNAs, altering gene expression and potentially treating arthritis, multiple sclerosis, and type 1 diabetes. The study identifies specific microRNA targets for controlling inflammation and immune response.
Biologists at the University of South Carolina have discovered a rare shark species, Sphyrna gilberti, which has a distinct genetic signature and is found only in the Santee and Pee Dee river systems. The discovery highlights the fragility of shark diversity and underscores the importance of studying evolutionary history.
A new study by the University of South Carolina reveals significant limitations in NHANES data, with most nutrition data being physiologically implausible and invalid for population-level analysis. This has serious implications for the role of energy intake in obesity and public health policy.
Researchers at the University of South Carolina have developed a graphene oxide membrane less than 2 nanometers thick with high permeation selectivity between hydrogen and carbon dioxide gas molecules. The team's method allows for uniform coverage without inter-flake leaks, enabling thinner membranes that can efficiently separate gases.
Recently published studies in Chernobyl and Fukushima Exclusion Zones reveal high frequencies of tumors, cataracts, and growth suppression in birds and pine trees. Lack of funding for independent scientists hinders understanding of radiation's impact on life.
Researchers have created a more systematic approach to synthesizing quantum dots, enabling the purification of semiconductor nanocrystals with uniform surface properties. The new method uses gel-permeation chromatography and has been shown to produce quantum dots with improved stability and reactivity.
