A study by Pitt researchers found that men and women have different genetic markers associated with severe depression, which may lead to better diagnosis and treatment strategies. The findings suggest that sex-specific genes for recurrent major depression may be the rule rather than the exception.
Research tracking over 700 children from adolescence to adulthood found that adolescents watching more than one hour of TV daily were more prone to violence. The link remained even after accounting for other factors like childhood neglect and low family income. The study's findings contradict the common assumption that media violence o...
A recent study suggests that statins may inhibit calcium growth on aortic valves in elderly people, potentially reducing the risk of cardiovascular events. Researchers found that those taking statins had a 62% lower median rate of calcium accumulation compared to non-statins group.
A study published in Health Education & Behavior found that community programs aimed at preventing teen pregnancy can reduce birth rates. The implementation of these programs led to a 15% decrease in birth rate in one area, while the other saw a slight increase.
Researchers at The Wistar Institute discovered that the Epstein-Barr virus (EBV) uses a telomere-like system to survive within its host cells. This finding has significant implications for treating EBV-associated cancers, as inhibiting this mechanism could potentially inhibit tumor cell growth.
Researchers have identified the mechanism behind tamoxifen's side effects, which may lead to the development of safer alternative medications. The study found that tamoxifen and raloxifene work differently in various cell types, with potential implications for breast cancer treatment.
The world's largest and highest-performance nuclear magnetic resonance spectrometer has arrived at PNNL. This unique system will enable scientists to study basic molecular processes and make new discoveries in fields such as DNA damage, disease development, and protein interactions.
Researchers found that managed care is associated with improved integration of inpatient and outpatient care, leading to lower hospitalization rates for chronic conditions. The study analyzed California trends and found a strong association between patient access ratings and reduced hospital admissions.
A study by the American College of Emergency Physicians finds that emergency department visits increased 27% from 1990-1999, with critically ill visits rising 59% and urgent visits increasing 36%. The number of beds per population also decreased, exacerbating the problem.
Aging cells retire when their telomeres become too short to function, according to a new Rockefeller University study. The researchers found that protein TRF2 helps critically short telomeres function better, allowing old cells to live longer.
Researchers found that vitamin supplementation reduced intimal index growth after heart transplantation, a common cause of arteriosclerosis. Vitamin C and E also maintained stable coronary endothelial function.
Teenagers are more likely to drive safely when their parents set restrictions and monitor their activities. The study found that adolescents who lack self-control or engage in deviant behaviors are at a higher risk of driving dangerously.
Researchers at UC Berkeley have developed a technology for creating cheap plastic solar cells that can be painted onto any surface, enabling applications such as powering wearables or small devices. The efficiency of the solar cells is currently low, but the team believes it has the potential to improve with further development.
Researchers discovered the ancestral role of VEGF protein guiding developing blood cells to their destinations. The findings suggest that blood vessels may have evolved from blood cells, a theory supported by studies on fruit fly embryos.
A new NIAID study found that diluting smallpox vaccine can expand the US vaccine supply fivefold, providing more protection against a potential outbreak. The trial used a freeze-dried live vaccinia virus vaccine and resulted in high take rates with minimal side effects.
A team of scientists from the University of Maine discovered a slow-growing sea urchin variety that never reaches legal size for harvesting in Maine's coastal waters. This finding suggests that harvesting legal-sized urchins could cause a shift in the population towards non-harvestable stocks.
Joanna Fowler has made significant contributions to positron emission tomography (PET), including the development of fluorine-18-fluorodeoxyglucose (FDG) and radiotracers for monoamine oxidase (MAO). Her work has improved our understanding of biochemical processes in addiction, aging, and drug action.
Researchers have discovered a new class of objects in two nearby galaxies, NGC 1023 and NGC 3384. These 'faint fuzzies' are thought to be about the same age as globular clusters but look and act differently, with sizes ranging from 50 to 100 light-years across.
Researchers from Oregon State University and others have found that Antarctica's ice sheets played a significant role in causing the Earth's sea level to rise by up to 70 feet in less than 500 years. This finding highlights the pressing need for better understanding of Antarctica's huge ice sheets and their stability.
A population study found that hypospadias was more than 20 times as common in boys whose mothers were exposed to DES during pregnancy. Research on exposure to DES may be relevant to current concerns about weaker oestrogens in oral contraceptives and other substances.
Researchers have discovered crystalline materials that can change shapes rapidly and act as ultrafast switches in optical computers, potentially enabling 3D TVs and unprecedented storage potential. The materials could be produced in bulk and reduced costs may be achieved through improved manufacturing efficiencies.
A team of researchers has discovered that the medial superior temporal area (MST) acts as both a compass and biological global positioning system, providing mental maps to help understand location and movement. This finding helps explain why people with Alzheimer's disease struggle to navigate their environment.
