Researchers found that marine mammals take advantage of buoyancy changes with depth, allowing them to glide rather than swim during deep dives. This strategy enables animals to extend their dives and conserve energy.
Researchers re-create chemical signatures thought to be produced only by living organisms in a laboratory setting. The team's findings suggest that simple chemical processes can account for the proportions previously believed to indicate past life, and may have implications for searching for life on Mars or other celestial bodies.
A new study suggests Reminyl, a treatment for Alzheimer's disease, provides significant cognitive and functional improvements in patients. The medication has been shown to delay the emergence of behavioral symptoms and maintain daily functioning for up to a year.
Researchers at McGill University have identified a novel receptor combination that could lead to new treatments for various neurological disorders. The discovery involves the interaction between dopamine and somatostatin receptors, which can produce synergistic responses when activated simultaneously.
A new, less invasive approach to removing a kidney from living donors has more than doubled the chance of patients receiving a transplant from a friend or loved one. The technique, combined with an educational program, has increased living donor transplants by half, with 40% of recent transplants coming from living donors.
Scientists have discovered a potential drug target for treating African sleeping sickness by identifying a unique metabolic pathway in the parasite. The discovery offers hope for developing effective treatments for the estimated 500,000 people affected by the disease.
University of Cincinnati researchers have developed new techniques to analyze selenium in food supplements, identify arsenic accumulation in seafood and sea plants, and speed up sample preparation using microwave energy. These advancements hold promise for environmental health, bioremediation, and understanding metal toxicity.
A psychologist has developed low-cost methods to reduce pharmacy errors, including the use of larger labels, focused task lighting, and self-monitoring journals. These inexpensive changes can significantly improve accuracy and are relevant for small community drug stores that may not have access to high technology.
Scientists are using harmonic analysis on satellite images to study changes in vegetation during growing seasons and land use patterns. They can detect desertification, forest regeneration, and climate change by analyzing wave patterns and amplitude measurements.
