A Penn State researcher found that few churches have adopted IT tools, leaving them out of funding opportunities. Churches can provide digital literacy to bridge the digital divide and support urban areas.
A new study reveals that modern humans originated from a small ancestral population in sub-Saharan Africa, with genetic splits occurring between hunter-gatherer populations and African farming people around 70,000-140,000 years ago. This finding supports the 'out-of-Africa' theory and provides insights into human migration patterns.
A NASA study found that urban heat islands in coastal cities like Houston cause warmer air to rise, interact with sea breezes, and create heavier rainfall. The study also suggests that this effect may be more pronounced near coasts.
A Penn State researcher found that less than 30% of drivers recognize the Slow Moving Vehicle (SMV) sign. The sign's inconsistent day/night appearance and potential confusion with other symbols contribute to the low comprehension rate. Improving motorist education and enforcement could help increase recognition.
Researchers found that women taking estrogen and progestin experienced a twice increased risk of dementia compared to those on placebo pills over a 5-year period. The most common type of dementia was probable Alzheimer's disease, accounting for 66% of cases.
A survey of US radiology residents found that most were hesitant to pursue breast imaging training or interpret mammograms due to negative attitudes and perceived drawbacks. The shortage of qualified radiologists is expected to worsen as demand for screening mammography services increases with an aging population.
A study by the University of Alberta has found that giving people drugs to treat back pain can improve performance. The research team led by Dr. Saifee Rashiq ran a randomized controlled trial where participants were injected with a strong narcotic painkiller and completed the Sorensen test, showing a significant increase in functional...
A novel flu vaccine developed by The Wistar Institute has generated a strong antibody response in mice, offering hope for a more stable and effective vaccine. The vaccine targets a stable region of the virus, potentially providing long-term protection against flu strains.
A recent study by Wake Forest University Baptist Medical Center found that combination hormone therapy increases the risk of probable dementia in women aged 65 and older, with approximately 23 additional cases per year. The study's results highlight the importance of considering alternative approaches to preventing cognitive decline.
The McGill University MNI de Grandpré Communications Centre has won the top prize in the International Room Competition, recognized for its innovative design and cutting-edge technology. The Centre's advanced features include multimedia presentations, videoconferencing, and state-of-the-art presentation equipment.
Vitamin A supplements have saved millions of lives by preventing childhood blindness and reducing mortality rates. Dr. Alfred Sommer's research also shows that supplementing women with vitamin A can reduce maternal mortality by an average of 45 percent.
Researchers in the Bahamas are creating one of the world's first marine reserve networks to preserve fish abundance and variety while maintaining fishing harvests. The study aims to design a sustainable fishing system through a multidisciplinary approach, incorporating economic, ecotourism, and political factors.
Researchers found that nearly half of men with elevated PSA levels had returned to normal levels after a year or more, making unnecessary biopsies possible. Repeating the PSA test after waiting at least six weeks may reduce unnecessary procedures and small incidental tumors.
A team approach combining medical tests, operative biopsies, and precise surgery successfully cured 31 of 34 newborns with focal congenital hyperinsulinism (HI). The procedure involves removing the diseased portion of the pancreas while preserving the rest of the organ.
Researchers aim to develop anti-microbial drugs by targeting enzymes in microbial pathways that synthesize essential amino acids. Structural information of these enzymes will be obtained using x-ray crystallography, paving the way for designing candidate inhibitors.
A study conducted at Lausanne University Hospital found that MDCT accurately depicted more spine fractures than conventional x-rays, with a sensitivity rate of nearly three times higher. This innovation could save time, money, and radiation exposure for patients admitted to emergency departments for severe trauma.
Researchers found a genetic connection between blood flow patterns and cardiovascular disease, with oscillatory shear stress leading to increased expression of the protein BMP4. This finding may help explain why physical inactivity promotes heart disease and could lead to new diagnostic tests or gene-based therapies.
A recent study published in Personality and Social Psychology Review by Christine Harris questions the evolutionary theory of sex differences in jealousy. She finds that men and women view sexual and emotional jealousy in a similar light, with many studies failing to account for individual variability and cultural influences. Harris su...
Scientists have successfully silenced mutant genes without affecting normal gene copies using RNA interference, a promising approach for treating diseases like Machado-Joseph disease, Huntington's, and Alzheimer's. This breakthrough technique has the potential to selectively turn off disease-causing genes, preserving essential normal g...
Scientists have found evidence of hot gases on the perimeter of the Coalsack, a cold dust cloud nearby the Milky Way. This discovery may help resolve debates about oxygen VI generation and provide new insights into star formation and galaxy energy production.
Scientists create a nanoscale, layered material that replicates the properties of mother-of-pearl, including its iridescence. The artificial nacre consists of alternating layers of clay and a polymer, providing strong, yet flexible, materials for various applications.
A massive tsunami is predicted to hit the Atlantic Coast on March 16, 2880, as a result of an asteroid impact. The simulation models a 2-mile diameter asteroid striking the ocean at 38,000 mph, generating waves up to 400 feet high and affecting coastal areas from Cape Cod to Cape Hatteras.
