Researchers discovered a novel mechanism controlling human growth hormone (hGH) gene expression through non-coding RNAs. This finding may lead to the development of therapeutics for hGH defects and a better understanding of genetic disorders.
Researchers at Indiana University are working on a project to craft messages that encourage women to be tested for HIV and enroll in research clinical studies. The study aims to identify barriers to testing and develop persuasive messages to overcome them.
Researchers find that chronic stress can lead to damage in the brain and body, but also note that certain behaviors like exercise, social support, and coping techniques can modify these effects. Healthy centenarians exhibit slower insulin rates, higher thyroid hormones, and lower cortisol levels compared to younger adults.
The Texas Smoke-Free Ordinance Database shows that over a quarter of Texas cities have passed new smoking ordinances since 2000. The database provides detailed information on smoking policies across the state, including summaries of various ordinances and enforcement measures.
A declaration by top scientists states that mercury pollution poses significant risks to human health, particularly for children and women of childbearing age. The declaration also highlights the need for reduced mercury use and emissions, as well as careful fish consumption to minimize exposure.
A new type of microscopy developed by Xiaowei Zhuang at Harvard University resolves objects as small as 20 nanometers, enabling the first ultra-resolution imaging of living biomolecules and cells. The technique, called stochastic optical reconstruction microscopy, uses glowing molecules to create high-resolution images in real-time.
A four-year study led by Temple University aims to test an internet-based telemedicine system to help overweight and obese African Americans lose weight. The program will be implemented through partnerships with several churches in North Philadelphia, where participants can access the study's website and moderated chat rooms for guidance.
Researchers found physical exercise can slow aging's effects and improve cognitive functions in older adults. Fitness training, particularly aerobic exercise, was associated with improved cognition, brain function, and retained brain volume.
A new CD-ROM containing more than 40 selected chapters from the HIV InSite Knowledge Base is being released to provide comprehensive HIV information in the developing world. The disk features a wide range of topics, including natural science, diagnosis and clinical management, transmission and prevention.
Research at Karolinska Institutet reveals that human neocortical nerve cells do not regenerate, contradicting previous studies on apes and rodents. The new method uses atmospheric C14 levels to pinpoint cell birth times, showing no cell division took place in the neocortex from infancy to adulthood.
Researchers at Indiana University School of Medicine found that routine screening for celiac disease in asymptomatic children with Down syndrome can have negative consequences on their quality of life. The study suggests that the cost of screening and treatment may outweigh the potential benefits, making it a less beneficial practice.
A new study confirms the effectiveness of MRI-guided breast biopsy by using specimen radiography to confirm lesion removal. Whole specimen and sliced specimen radiography proved valuable in detecting lesions, identifying pathologists' findings, and locating fractured biopsy needle wires.
A comprehensive review published in Nature Clinical Practice Endocrinology & Metabolism suggests that Western diets are causing hormonal imbalances in children, leading to overeating and obesity. The study attributes the rise in childhood obesity to an environment with high-calorie, low-fiber foods.
Research suggests that women's appreciation for their body is key to adopting better eating habits. According to the study, intuitive eaters reported higher levels of self-acceptance and less time spent thinking about appearance. This finding contradicts common messages that some degree of body dissatisfaction is healthy.
Researchers found two opposing mechanisms protecting cells from protein aggregation: one breaks down aggregates, while the other transforms smaller ones into less toxic high-molecular-weight aggregates. This discovery may lead to new therapies for age-related Neurodegenerative Diseases.
The College of Engineering at UC Santa Barbara has received a $2.75 million Partnerships for Research and Education in Materials (PREM) award from the National Science Foundation to partner with Jackson State University (JSU). The grant aims to develop new materials research in organic semiconductors and optical nanosystems, while focu...
Researchers studied ancient Arctic water cycles during a period of rapid, extreme global warming 55 million years ago. The study found that increased precipitation led to lower ocean salinity and drastically lower oxygen levels in the Arctic Ocean, similar to predicted effects of greenhouse gases.
Research by Phyllis Moen finds that middle class dual-earner couples are stretched thin, with fewer than one in six qualifying as 'super couples' with high quality of life. Women working in insecure jobs often face limited scheduling flexibility and control.
Montana State University has developed a massive database of wind turbine material tests, spanning over 17 years and involving 150 different composite materials. The MSU/DOE Fatigue Database for Composite Materials is now one of the world's largest open-access libraries on wind energy research.
Researchers at Rensselaer Polytechnic Institute develop a virtual simulator that allows surgeons to practice minimally invasive surgery with actual tool handles, improving depth perception and dexterity. The system uses haptic technology to provide an immersive experience, reducing the need for cadavers and animals in training.
A survey found that one-third of Americans reject evolution, a higher figure than in European countries. Fundamentalist religions and politics play a significant role in this disparity.
A special issue of Nursing Research journal highlights innovative methods for treating tobacco dependence and practical approaches for clinical use. Nurses are widely recognized as central to global efforts to reduce the detrimental health effects of tobacco use, with training needed to deliver interventions to patients.
