The NASA Earth Observing System (EOS) Global Change Media Directory 2001 features over 343 scientists from 50 disciplines, including climate change, natural hazards, ozone, water resources, and global warming. The directory contains a list of experts with complete contact information.
Researchers found that women hospitalized for heart disease can benefit from nurse-managed relapse prevention programs, which teach coping strategies and provide social support. The programs have been shown to be feasible and well-accepted by both patients and healthcare providers.
A new study found that people in unhappy relationships with mild high blood pressure experience sustained increases in blood pressure, while those in loving relationships show a decrease. The research suggests that marital distress may be a significant factor in raising blood pressure in vulnerable individuals.
The international Arabidopsis Genome Initiative has successfully completed the sequencing of the entire genome of Arabidopsis thaliana, a powerful tool in plant molecular biology. The study reveals vast chromosomal regions have been duplicated in the genome, and approximately 70% of genes can be functionally predicted.
Researchers aim to understand how sonar affects marine creatures by creating a sea sound simulator. The ESME project will analyze data from various organizations and develop mathematical models to predict environmental effects of different sonar types.
A team of scientists has successfully completed the sequencing of the Arabidopsis thaliana genome, paving the way for accelerated research in plant biology. The comprehensive analysis provides valuable insights into gene annotation, functional categories, chromosomal architecture, and transposable elements.
Geologists propose that high-pressure ice could accumulate in planetary interiors during subduction, potentially influencing tectonic activity and volcanic eruptions on Earth and Mars. This process may also impact the planet's thermal balance, with changes in water state affecting dynamics and evolution.
Researchers analyzed data from over 500 cases of bladder cancer and found that smoking increases the risk. Coffee drinkers who also consumed tobacco were three times less likely to develop bladder cancer than non-coffee drinking smokers.
A recent study published by the Mayo Clinic has found that estrogen plays a crucial role in preventing bone resorption in elderly men. The research suggests that estrogen is essential for maintaining optimal bone metabolism in aging men, and highlights the importance of osteoporosis prevention for this demographic.
The targeted disruption of the PCI gene in mice leads to profound defects in sperm development and fertility. Human male infertility is also associated with a lack of PCI in seminal fluid, disrupting the balance of proteinases and proteinase inhibitors.
A study by Richard Weyers predicts that the US bridge transportation system alone will require a trillion dollar investment. The expert warns that epoxy-coated reinforcing steel is prone to corrosion, especially when used in saltwater environments.
Researchers at Cedars-Sinai Medical Center found that 78% of patients with IBS had excessive bacteria in the small intestine. Treatment with antibiotics reduced symptoms in most patients, suggesting a strong association between SIBO and IBS.
A study of British adults found that most men follow a beer and fast food diet, while women prefer the traditional British diet. The research also revealed significant regional and socioeconomic differences in dietary patterns, with those on low incomes and smokers consuming less healthy diets.
The Navy's BMP program has significantly reduced disparities in quality, cost, and reliability of acquired goods and services. More than 120 surveys have been conducted, 5,000 best practices documented, and an Internet site established to share knowledge and expertise with the business community.
In mice lacking b7 integrins, B cell-mediated secretion of antiviral IgA is lacking, and CD8+ T cells reach the intestinal epithelium in smaller numbers. Despite this, these cells are sufficient to clear rotavirus efficiently from the gut.
A large-scale epidemiology study found that patients with TIA are at high risk for stroke, cardiovascular events, and death within 90 days. The study identified five independent risk factors associated with increased stroke risk, suggesting that aggressive treatment and targeted therapies may reduce stroke incidence in TIA patients.
Researchers at Cornell University have successfully demonstrated hybrid nanodevices that can administer drugs and treatments using biomolecules and tiny nickel propellers. The devices are powered by ATP and can be assembled, maintained, and repaired using life's physiology.
Researchers analyze kinetics of amyloid b1-40 peptide clearance in mice brains, finding vascular transport is primary mechanism. They also suggest ApoE plays role in amyloid clearance pathway.
The team sequenced the genome of Arabidopsis thaliana, a flowering mustard, enabling scientists to study genes controlling basic plant functions. The knowledge gained will aid in improving crops like wheat, corn, and soybeans, as well as identifying genes in the human sequence.
Scientists have developed a unique way to study elephant seals using tiny sensing devices attached to their coats. These devices provide valuable information on sea temperatures and pressure, even at depths not normally reached by research ships or satellite sensing.
A study by Dr. William S. Breitbart found that clinical depression and hopelessness are key factors contributing to a patient's desire to die, even more important than physical pain. The study suggests that addressing psychological needs is crucial in minimizing the desire for death.
High-tech entrepreneur Michael J. Fitzpatrick and his wife, Patty, are donating $25 million each to establish new centers for advanced photonics at Stanford and Duke universities. The centers will attract top students and faculty, and facilitate industry partnerships to develop cutting-edge photonics technologies.
The completed Arabidopsis genome provides a roadmap for understanding plants to improve nutrition and health. Monsanto contributed to the effort through Cereon Genomics, releasing over 40,000 genetic markers that increased the resolution of genetic maps used by researchers.
A study found that pneumatic compression and extended anticoagulant drug therapy lower the risk of developing symptomatic blood clots after hip replacement surgery, with overweight patients most at risk. Pneumatic compression was effective in normal-weight patients, while warfarin therapy benefited all patients.
