Recent research suggests that West Antarctic ice streams are experiencing normal variability, contrary to predictions of imminent shutdown and sea-level rise. The study found that local conditions, such as geothermal heat and frictional forces, drive the slowdown or speeding up of ice streams.
A three-year grant awarded by EPA aims to develop a scientific way to accurately estimate pesticide exposure among children, especially farmworker sons and daughters. Researchers use novel methods like videotaping children at home to quantify real-life exposure to pesticide residues.
Researchers discover that a platelet molecule called phosphatidylserine plays a key role in activating the final step of blood coagulation. The finding could lead to new treatments for clotting disorders, such as heart attacks and strokes.
Researchers have developed a computer model to visualize gravitational waves produced by black-hole mergers, providing insight into Einstein's theory of general relativity. The model predicts that the waves will be relatively weak until moments before the merger, culminating in a thunderous impact.
A school program called CATCH significantly increased moderate to vigorous physical activity, decreased fat in meals, and reduced sodium content. The program's effects were more pronounced than expected, with substantial increases in physical activity levels.
Researchers measured the chemical reactions and light emission from a single water bubble excited by sound waves, finding temperatures high enough to break water molecules apart. The experiment showed that only a small fraction of sound energy is converted into light, with most energy going into mechanical energy.
Researchers at McGill University have made a significant breakthrough in profiling the yeast genome, creating a comprehensive scale for genetic manipulation. This achievement could ultimately lead to the discovery of better drugs for treating human diseases, including certain forms of cancer.
Researchers at the University of Illinois have developed a new molecular imprinting process to create artificial antibodies. The technique involves imprinting a single molecule within a highly branched polymer called a dendrimer, allowing for specific binding and rejection of target molecules. This breakthrough has potential applicatio...
Researchers at Case Western Reserve University are developing an innovative drug delivery device using liposomes to target damaged areas of arteries in cardiovascular disease. The device aims to improve treatment outcomes and reduce mortality rates associated with cardiovascular disease.
Researchers used sensitive detection techniques to study energy dissipation during bubble collapse, finding that less than 1% of energy is converted into light and most goes into chemical reactions or mechanical energy. This understanding has implications for future work on sonochemistry and the possibility of sonofusion.
Defects in enzymes responsible for processing dystroglycan protein cause several rare forms of muscular dystrophy. The discovery will help doctors diagnose and provide genetic counseling to patients. It also raises questions about links between muscle physiology and neurobiology, potentially improving understanding of learning and memory.
Researchers at Case Western Reserve University discovered kinks in the aggrecan protein, a submolecular root of arthritis. The study shows that these kinks may be more susceptible to enzymes that degrade cartilage in osteoarthritis, providing a link between structure and function.
A recent study found that antiretroviral therapy targeting the central nervous system can improve neurological symptoms in HIV-infected children. The treatment was shown to reduce the amount of virus in their brains and improve developmental milestones.
A study found that middle school students who participated in a nutrition program with repeated messages and support had significant increases in fruit and vegetable consumption, while those without the program saw no change. Researchers emphasize the need for intensive, multi-component interventions to reach these children.
New studies reveal close connections between North Atlantic and Pacific climates, with potential implications for predicting future climate changes. Glacier advances in Alaska and landslides triggered by asteroid impacts provide evidence of distant climate perturbations.
A new study reveals that men are on average twice as likely to die prematurely as women at every age, particularly in their twenties. The disparity holds true for various causes of death, including car crashes and heart disease. If male mortality rates matched female rates, over 375,000 lives would be saved annually in the US.
A computer system developed by Newcastle University researchers accurately predicted the spread of breast cancer and five-year survival rates in nearly 90% of patients. The system uses a combination of neural networks and fuzzy logic to analyze images of cells from tissue samples.
A recent study found a significant change in the types of bacteria involved in early-onset sepsis in low-birth-weight infants, with an increase in E. coli cases and antibiotic-resistant strains. The shift raises concerns about the impact of increasing antibiotic use during labor on these vulnerable infants.
