A University of Toronto study found the chance of needing a second operation following primary knee replacement surgery was between four and eight percent, half the rate expected by family doctors and rheumatologists. Younger patients with active lifestyles and those living in urban centers had slightly higher risks of follow-up surgery.
A new study published in Archives of Internal Medicine suggests that lean cuts of red meat can be part of a heart-healthy diet. Researchers found that subjects who consumed 80% lean red meats had nearly identical changes in cholesterol levels compared to those who ate lean white meats.
Research by Leslie Ries and colleagues found that restored prairie along roadsides increases the number of sensitive butterfly species, with twice as many rare butterflies present compared to grass and weeds. This could provide crucial corridors for butterfly habitats, reducing road-crossing risks.
A team of researchers at Ohio State University has created a single, reliable system that combines three sensing techniques to inspect the quality of high-power laser welds. The system can detect faults with significantly better accuracy than individual sensors alone, and is estimated to cost around $7,500 for manufacturing partners.
A new study by Ohio State University found that men and women agree on the characteristics of a 'sexual person', prioritizing love, compassion, and sensitivity. Men who scored high on sexual self-concept were more likely to be in relationships and experience feelings of love.
A recent AAP recommendation suggests that young children with simple febrile seizures do not need anticonvulsant medication, instead aiming to prevent unnecessary testing and drug therapy.
Researchers captured images of brain activity while students learned an associative task on a computer, revealing a network of brain activation. The study confirms that learning and awareness involve multiple regions acting in concert, contradicting the traditional view of the prefrontal cortex as sole responsible.
International documents from the Antarctic Treaty System are now available in an easily-searchable database on the World Wide Web. The technology provides a visual display for collapsing large amounts of information into an expandable hierarchical structure.
Researchers at U of T have created a new kind of luminescent silicon film that emits and transmits photons, a significant step forward in photonics. The discovery holds out the promise of new improved light-emitting diodes, optical interconnectors, displays, and chemical sensors.
A study by Ohio State University found that divorcing parents who attended a parent education seminar reported better parent-child relationships than those who did not. The program was most effective during the first four years following divorce, with participants showing improved closeness and satisfaction with their relationship. Des...
Researchers found that digital exams nearly doubled vaginal bacteria entering the cervix and uterus in 80% of patients. Potentially harmful bacteria like Group B Streptococcus and E. coli were isolated from cultures, posing a risk to newborns.
A new study reveals that gastric bypass surgery significantly improves health perception outcomes in severely obese patients, surpassing non-obese control groups in four categories. Patients report improved social functioning, emotional well-being, pain relief, and vitality after weight loss.
Research reveals penguins can quickly acclimate to tourists visiting their breeding colonies, with reduced stress levels after brief exposure. After 10 days of repeated human visits, penguin stress levels decreased significantly, suggesting a possible long-term adaptation to ecotourism.
Researchers at Purdue University have developed a method to create smaller, faster computer chips by stacking electronic devices in vertically connected layers. The technique, called epitaxial lateral overgrowth, allows for the creation of multiple layers of transistors with extremely short connections, leading to faster and denser cir...
The gray wolf population is thriving in Yellowstone, with 10 breeding pairs established in each of the three states. The reintroduction of wolves has boosted biodiversity, reducing elk and coyote populations while increasing eagle, pronghorn, foxes, and wolverine numbers.
The USGS report found complex mixtures of nutrients and pesticides in streams with significant agricultural or urban development. However, concentrations of individual pesticides were often lower than current U.S. Environmental Protection Agency drinking-water standards.
Researchers at Ohio State University have found signs of a compact, supermassive object at the center of galaxy NGC 5548, suggesting the presence of a black hole. The study used data from the International Ultraviolet Explorer satellite and ground-based telescopes to analyze changes in light from the galaxy's active galactic nucleus.
Researchers found that sites with high agricultural land had a stronger correlation with red-legged frog declines than UV radiation or global warming. The study suggests that wind-borne pesticides from the Central Valley may be contributing to the frogs' decline in the Sierra Nevada foothills.
