A study published in The Journal of Clinical Endocrinology and Metabolism found that excess glucose consumption stimulates the generation of free radicals, which can damage cells lining blood vessels. The researchers also observed a decrease in levels of a-tocopherol, a powerful antioxidant.
American bullfrogs are non-native to western Canada, but their population is expanding rapidly due to human activity. Purnima Govindarajulu, a UVic graduate student, is studying the impact of these invasive frogs on native species and ecosystems.
LSU will create a new engineering discipline to address design concepts behind buildings and infrastructure in hurricane-prone regions. The program will offer courses in civil engineering and disaster engineering for upper-level undergraduates and graduate students.
Researchers found that individuals with autism spectrum disorder (ASD) performed better on a 'false-memory' test due to their impaired ability to use context. This improvement enabled them to recognize words that had been on a word list, while non-autistic subjects struggled with false memories. The study suggests that high-functioning...
Researchers found two stages of age-related deterioration of sleep quality: the first between young adulthood (16-25) and mid-life (35-50), and the second after age 50. Changes in sleep quality were mirrored by changes in hormone secretion, particularly growth hormone, which declined significantly with age.
Researchers found that celecoxib reduced breast tumor incidence by 68% and average tumor size by 81% in rats. The anti-tumor effects of celecoxib are attributed to its ability to inhibit an enzyme that promotes cancer growth.
A new system of planting different varieties of rice plants can significantly reduce problems with the fungal disease 'blast', which causes lesions on rice plants, reduces yields and in severe cases can kill entire crops. This approach has been shown to eliminate losses to blast in some types of glutinous rice.
A study by Prof. Arnold Labrie explores how desire for purity emerged as a response to societal changes, masking a preoccupation with the impure. The concept of purity is closely tied to order and excludes those deemed 'impure', reflecting underlying tensions between traditional values and emerging modernities.
Electrons may undergo fission in liquid helium at temperatures near absolute zero, violating the long-held notion that elementary particles cannot be broken into two pieces. Experimental evidence supports this theory, which suggests that light can cause an electron's bubble to divide into smaller bubbles.
A recent survey in the Netherlands reveals that chronic pain affects approximately 18% of the population, with frequent problems including lower back pain and abdominal pain. The study highlights the need for more research into the effects of treatment methods, as current evidence is often inadequate or contradictory.
A new study reveals that over 100 countries have laws that can imprison journalists for 'insulting' government officials and institutions. The World Press Freedom Committee sponsored the research, led by Dr. Ruth Walden, which found that such laws undermine democracies and stifle free speech.
Researchers found that long-term memories become labile every time they are retrieved, making them susceptible to alteration or disruption. The process of reconsolidation, which involves the generation of new proteins, is necessary to store long-term memories without retrieval.
Researchers at Johns Hopkins Medicine found that cochlear implants improve quality of life and save $50,000+ over a child's lifetime. The study provides evidence that pediatric cochlear implantation is highly cost-effective from a societal perspective.
Research found that low dietary vitamin C intakes are associated with higher rates of periodontal disease, particularly in smokers. Vitamin C's antioxidant properties play a crucial role in maintaining healthy connective tissue and combating oxidative stress.
