A University of Florida study found that married individuals, particularly whites, are less likely to recommit crimes. In contrast, unmarried men, including those from minority groups, are more likely to engage in criminal activity due to the lack of structured schedules and employment.
Researchers at Lawrence Livermore National Laboratory confirmed that waters migrating from the surface to the water table in drier regions can take many tens of thousands of years. These waters, which began their migration at the last ice age, hold a scientific and historical record of global climate change.
Researchers successfully immobilized an enzyme called organophosphorus hydrolase, nearly doubling its activity levels. The breakthrough could lead to the development of novel sensor and decontamination systems for homeland security and environmental protection.
A study by Nikola Pavletich and colleagues reveals that BRCA2 protein binds to damaged DNA, repairing it. This discovery sheds light on the mechanism of breast cancer development and opens new avenues for treatment strategies.
Despite a state budget crisis and terrorism, Virginia remains positive in its assessment of the state's qualities. Virginians report satisfaction with friendships, family relationships, education, medical care, retirement options, and vacations.
A new study published in Obstetrics and Gynecology found that oral contraceptive use during adolescence is not associated with weight gain or increased body fat. Researchers monitored 66 female participants, aged 16-21, for four years, tracking their blood lipid patterns and body composition.
The National Human Genome Research Institute (NHGRI) has upgraded the priority of cow, dog, Oxytricha trifallax, and Trichoplax genomes to high or moderate based on medical and biological opportunities. The genome sequences are expected to speed up studies of these agriculturally important animals and have medical benefits for dogs.
Scientists have unraveled the mystery of membrane fusion, a process crucial for gene therapy and drug delivery. By analyzing X-ray diffraction patterns, researchers revealed that membrane fusion begins with an hourglass-shaped structure called a stalk.
A new study reveals three distinct species of African elephants: savanna, forest, and west African. The west African population has been diverging for over two million years and is threatened with extinction due to human activities.
A Cornell University project explores the complex relationship between Kenyan small farmers, their communities, and the land they depend on. The research highlights the devastating effects of soil degradation, leading to reduced crop productivity and increased poverty. Understanding social and cultural factors is crucial in addressing ...
Head lice are becoming increasingly resistant to specialized shampoos, with 50-98% remaining after treatment. Researchers use artificial 'scalp' to study the pests on a genetic and molecular level, seeking alternative treatments.
Children's Hospital researchers estimate national costs associated with bicycle handlebar-related injuries, which can result in lengthy hospital stays and long-term disability. The study recommends adopting safer designs and educating parents on choosing and maintaining bicycles to minimize the risk of such injuries.
A home-based preschool program in South Carolina has shown significant improvement in disadvantaged children's school readiness and academic performance. The program, which provided twice-weekly visits to families from low-income backgrounds, resulted in higher test scores compared to the general population.
Researchers uncovered characteristics of faults that move backwards, contrary to conventional observations, and found the material within faults is significantly different than its surroundings. The study provides a new way to identify potentially active faults and better understand the earthquake process.
Researchers have discovered a key molecule involved in regulating the immune system that may contribute to stomach cancer. Mutations to this molecule, gp130, induced cellular changes reminiscent of early gastric cancer in mice, highlighting a potential new target for treatment.
Researchers identified 216 'stemness' genes that are active in embryonic, neural, and hematopoietic stem cells. These genes are involved in coping with stress, signaling, and self-renewal, and can aid in developing techniques to induce stem cells to differentiate into specific adult cells.
A recent clinical trial found that tamoxifen reduces the frequency of breast cancer by a third in women at increased risk. However, tamoxifen use also increases the risk of blood-clotting complications, which may contribute to higher death rates.
Researchers observe temporary structure during membrane fusion, forming hourglass-shaped stalk connecting two membranes. This discovery may lead to understanding of viral infection and designing new drug delivery methods.
Researchers at Princeton University identified a core set of genes responsible for regulating stem cell behavior and unique activities. The study also uncovered over 4,000 genes active in surrounding tissues that influence stem cell behavior.
Researchers found that using a mesh patch for large hiatal hernias results in no recurrence of the condition, marking a significant improvement over traditional surgical methods. This breakthrough study provides new hope for patients with large hiatal hernias, offering an effective and lower-risk treatment option.
Researchers at Memorial Sloan-Kettering Cancer Center have uncovered the function of the BRCA2 protein, which interacts directly with DNA to repair genetic damage. This new understanding sheds light on how mutations in the BRCA2 gene contribute to inherited breast and ovarian cancers.
Researchers at Purdue University have found that chlorine dioxide gas is highly effective in killing bacteria on food surfaces, particularly Listeria monocytogenes. The study showed significant reductions in bacterial populations on apple skin, stem cavity, and calyx using the gas.
Researchers found that benzene derivatives have higher neurotoxic potency than previously thought. The study suggests related aromatic chemicals may also damage the nervous system, with potential applications as a biological marker of exposure.
In Angola, displaced people turn to family members, neighbours, and church groups for advice and consolation in the form of conselho. This community-based approach emphasizes shared suffering and practical help over Western-style counseling. Local perspectives are crucial for culturally relevant psychosocial interventions.
