Researchers aim to recruit at least 100 African-American families with a history of prostate cancer to participate in the PROGRESS study. The study seeks to identify genes linked to inherited prostate cancer, which may help diagnose, treat, and prevent the disease.
A study published in The American Journal of Clinical Nutrition found that a father's percent body fat predicted the pattern of weight gain in their daughters. The researchers analyzed data from 47 pre-pubescent girls, finding that only the father's weight correlated with the daughter's weight gain patterns.
Researchers analyzed 15,414 student and faculty yearbook photos to pinpoint the age when girls begin smiling more often than boys. The study found that girls start smiling significantly more than boys as early as the fourth grade, with a widening gender gap by high school.
Researchers at Purdue University have solved the structures of two large icosahedral viruses, providing insights into their assembly and potential applications in antiviral agents. The viruses' shells are made up of large building blocks joined primarily in clusters of three, forming stable and highly symmetrical structures.
The USGS is launching a citizen science program to monitor frogs and toads across the United States. Volunteers will collect data on local amphibian populations, helping scientists understand the decline of these species worldwide.
VRAM memory has the potential to replace mechanically driven storage media, reducing transistors needed for lower cost and retaining information without constant refreshing. The technology is well-suited for space, avionics, and shipboard applications due to its high-density, non-volatility, radiation-hardness, and low-power attributes.
A study found that genetic variations can cause individuals to be more resistant to a cholesterol-lowering diet or at greater cardiovascular risk from a high-fat diet. Apolipoprotein B gene polymorphisms were associated with increased plasma total cholesterol concentrations in certain genotypes.
A recent study found that the genetic marker associated with periodontal disease in people of European heritage is barely present in Chinese populations. This suggests that oral hygiene habits, smoking, and other risk factors may be more important in explaining the high prevalence of periodontal disease in Chinese populations.
Researchers have identified a bacterial strain called T1 that can break down toluene, a hazardous industrial solvent. This discovery could lead to more cost-effective and environmentally friendly methods for cleaning up contaminated sites, reducing the need for expensive excavation and disposal methods.
A 12-week study found that carotenes and vitamin E supplements reduced sunburn intensity in fair-skinned individuals. The duration of supplementation was more effective than dosage in protecting against sunburn damage.
Researchers identified a biological marker that predicts breast cancer return in some women, with higher levels of damaged p53 protein found in those whose cancer recurred within four years. The finding may lead to personalized treatments, such as higher doses of radiation and novel therapies.
A recent study reveals that children with Down syndrome are susceptible to severe periodontal disease due to factors such as inadequate oral hygiene and congenital deformities. Research suggests that proper plaque control can help ward off the disease, emphasizing the importance of regular dental visits and education for parents.
A study found African American children exhibited more risk factors for diabetes and cardiovascular disease than white children, despite healthier diets. The authors cautioned that the diets in this study were of poor quality according to national recommendations.
A new study by Dr. Hilke Brockmann found that German mothers' attitudes towards the sex of their children have changed over time in response to changes in welfare regimes. In contrast to Asian and African countries where sons are preferred, Germany's high level of female participation in the labor market may lead to a girl-preference.
A University at Buffalo professor is using the case-study approach to revolutionize the teaching of science, resulting in improved student attendance and engagement rates. The grant will establish a national center for case study teaching in science, providing faculty with training and resources.
Researchers are conducting a national genetic study to identify the genetic markers that contribute to Parkinson's disease. The study aims to enroll 600 pairs of siblings with Parkinson's disease, using information from the U.S. Human Genome Project to isolate genetic markers.
A recent study reveals a new parameter regulating cell attachment, which is influenced by the physical properties of the surrounding environment. The rigidity of the matrix affects cell adhesion dynamics, leading to the formation of different types of adhesions.
Research suggests that emergency rooms can reduce children's pain and anxiety during procedures by using techniques such as topical anesthesia, nitrous oxide, and psychological interventions. Effective communication with parents is also crucial in minimizing their own anxiety while ensuring their child's comfort.
A study found that male mangabeys in secondary forests weigh less and are more likely to leave their groups, making them vulnerable to predators. The research suggests that logging may impact the health and behavior of primates in African forests.
