The region's labor force growth rate was the second-lowest among nine geographic divisions, with women accounting for all 100% of growth during the 1990s. Declining native-born male workers have contributed to record low unemployment rates and growing labor shortages.
Researchers found that low potassium intake increases stroke risk, while increasing potassium in the diet may help prevent strokes. Diuretics used to treat high blood pressure and other conditions were also linked to an increased risk of stroke in people with low potassium levels.
A new study suggests that women with Polycystic Ovary Syndrome (PCOS) and their siblings with hormone problems have the same gene defect. The study found that approximately 50% of PCOS sisters had elevated androgen levels, while PCOS brothers had significantly elevated DHEAS levels.
Dr. Laura Hawryluck argues that administering neuromuscular blockers can blur the lines between palliative and euthanasia care. She suggests that physicians should prepare family members for the reality of a dying patient's breathing and bodily reactions.
Researchers have developed a new technique to improve earthquake resistance in highway structures using epoxy and flexible materials like glass or carbon fibres. This method can strengthen concrete structures up to five times and extends their lifespan, providing crucial seconds for evacuation during earthquakes.
Researchers at Georgia Institute of Technology have created the world's smallest electroluminescent light source using individual silver molecules. The technique can lead to new optical interconnects, microscopy, and lithography applications. By applying high-frequency alternating current, they observed a dramatic enhancement in response.
The new technology uses small electric crystal chips that can be embedded into products and read by electromagnetic scanners, providing unique identification for individual items. The tags can be used for tracking, inventory management, and logistical tasks, offering possibilities such as checkout-free shopping.
Scientists at ONR have created a novel technique to hide information within the naturally occurring fluctuations of light polarization in optical fibers. The signal is modulated onto these variations, making it nearly impossible for unauthorized parties to intercept and decode the message.
Researchers suggest that the concept of teenagers emerged between the 13th and 17th centuries in western Europe. Young people in this age group engaged in various activities such as sports, education, and work, but also faced societal pressures like marriage and violence.
Researchers used DNA sequences to identify hybridization and introgression in Phlox species, tracing the Eurasian source of invasive Tamarix species. The study found that a novel hybrid plant genotype is contributing to the invasion's spread, affecting biodiversity and hydrology in fragile environments.
Scientists have created mice that can eat rich, high-fat diets without accumulating fat or risking diabetes. The mice lack the SCD-1 gene, which produces an enzyme required for fat tissue production. Instead of storing excess fat, the mice metabolize it, increasing energy expenditure and oxygen consumption.
A seven-year study found that elderly individuals with depressive symptoms were more likely to develop Alzheimer's disease and experienced rapid cognitive decline. The risk of developing AD increased by 20% for each additional symptom.
Researchers at the University of Toronto found that brain music reduced anxiety and improved sleep in subjects with insomnia lasting at least two years. The customized music created specific brain wave patterns, leading to more pronounced effects than placebo music.
Research by Dale Rublee and colleagues suggests that treating patients with sepsis with antithrombin III improves quality of life but not survival chances. Patients treated with the drug show marked improvements in social and psychological functioning, highlighting a new focus needed in clinical research.
Researchers at Cedars-Sinai Medical Center have found that a potent experimental drug called 2C4 slows tumor growth in both breast and prostate cancer tumors in mice, even when small amounts of HER-2/neu are expressed. The study's findings may lead to a new way to treat breast and prostate cancers.
A new compound is being developed to target specific types of hearing loss, with the goal of repairing and regrowing injured or damaged auditory hair cells. The treatment aims to prevent hearing loss by bolstering the inner ear's antioxidant defenses and may offer hope for some patients with sudden hearing loss.
