Researchers at Ohio State University found that people with high hostility and anger levels showed higher homocysteine concentrations, associated with coronary heart disease. The study also revealed that men are more likely to have higher homocysteine levels due to increased hostility and inhibition of anger.
Researchers at National Jewish Health discovered how proteins IL-15 and IL-2 work together to control the immune response against viruses. The proteins balance the production and division of memory killer T cells, allowing the immune system to battle antigens with a controlled response.
Researchers have discovered that synuclein plays a crucial role in communication between neurons, potentially shedding light on the mechanisms underlying Parkinson's and Alzheimer's diseases. The study provides strong evidence that synucleins control the release of neurotransmitters from nerve cells.
Scientists analyze melt inclusions in Hawaiian crystals, finding highly unusual trace-element contents that match a specific rock type. The study confirms a giant recycling process where ancient oceanic crust is melted and re-formed in the Earth's mantle.
Case Western Reserve University researchers have developed a prototype of a miniature fuel cell with a volume of five cubic millimeters. The new cell uses hydrogen as a fuel and is produced using high-tech micro-fabrication techniques, enabling low-cost production.
After a 13-year study, researchers found no significant increase in cancer mortality among TMI residents. Initial results showed higher mortality from heart disease, but these were largely attributed to smoking habits and education levels.
Researchers found that cow clones exhibit youthful telomeres, indicating a potential for increased lifespan, whereas normal cells age prematurely. This breakthrough erases doubts about cloning's utility by showing it doesn't rob cells of their normal lifespan.
A large randomized clinical trial shows that self-hypnotic relaxation techniques can decrease pain medication use, reduce operating room time, and improve vital signs during surgery. The study's findings suggest that hypnosis can be a safe and effective method for reducing anxiety and pain in patients undergoing invasive procedures.
French researchers develop gene therapy to treat human severe combined immunodeficiency (SCID) X1, a life-threatening disease. Two infants experience 'striking' clinical improvements and return to normal immune system functioning without side effects.
University of Florida researchers have developed a molecule that can rearrange genes or monitor their impacts, enabling the study of genetic disorders. The synthetic DNA beacon has also been used to detect toxins in single cells, potentially leading to earlier diagnosis and treatment.
Scholz et al. study reveals significant genomic differences between Neandertal and human fossils, suggesting separate evolutionary histories. The researchers used a novel method to assess cross-hybridization of fossil DNA, allowing them to distinguish two well-defined Neandertal fossils from modern humans.
