Researchers create a new test method that detects nanometer-scale holes, free radicals, and cross-linking in paints, allowing for early detection of damage and more efficient development of durable paints. This breakthrough could lead to cost-effective solutions for bridge coatings and other applications.
Researchers found that brain steroid allopregnanolone mediates many of alcohol's effects, including anti-anxiety and anticonvulsant actions. The study suggests that blocking this compound may inhibit alcohol's sedative-hypnotic effects.
Researchers at Harvard Medical School have coaxed high-level neurons in adult zebra finches to be replaced by their own endogenous precursor cells, demonstrating the potential for brain repair and regeneration.
Researchers used harmonic radar to track honey bees during orientation flights, revealing they learn to navigate by flying faster and visiting more areas. The study suggests that orientation flights allow bees to adapt to new environments, but the scientists still want to know why some bees take more or fewer flights.
Scientists discover that people prefer certain smells when sniffed through one nostril over the other. The left nostril is more accurate for identifying odours, while the right nostril enhances pleasantness perception. This finding fits with brain processing theories and may lead to further research on smell perception.
Researchers found that rats born by Caesarean section showed marked differences in brain development compared to naturally born controls. They had altered dopamine systems and responses to stress tests. The findings hint at a potential link between Caesarean births and schizophrenia risk.
Researchers found that brain areas active during eye movements also control visual attention, shifting focus to peripheral areas. This discovery suggests a shared neural basis for these functions, with potential implications for understanding early mammalian cognition and primate social behavior.
Researchers have found that stunted brain regions may cause severe autism symptoms, while smaller regions may lead to milder symptoms in close relatives. The study used magnetic resonance imaging to compare the brains of identical twins with and without autism.
Scientists successfully used gene therapy to correct deafness in shaker-2 mice by identifying a recessive mutated gene responsible for the condition. The study's findings also revealed that the mutation affects a myosin enzyme involved in inner ear development, which is crucial for hearing.
The symposium brings together experts to present on recent findings in the science of emotion, including how environment impacts brain development and can affect emotional health. Researchers will also share insights into the effects of early nurturing and experiences on emotional memory and trauma.
A team of researchers from Duke University found that the hypoglossal canal, which controls tongue movement, is larger in humans and Neanderthals than in apes and proto-humans. This discovery challenges the theory that human speech may not have arisen until around 40,000 years ago.
A recent study has found a link between methylmercury exposure in pregnant mothers and neurological delays in 7-year-old children. The research, conducted in the Faroe Islands, used sophisticated neuropsychological and neurophysiological techniques to examine the effects of prenatal mercury exposure on brain development.
A study using brain scans found that structures on the right side of the brain are involved in anxious thoughts and processing new inputs. The right frontal lobe, basal ganglia, cerebellum, and pontine nuclei were identified as key areas.
A new study by German neurologists found that transcranial color-coded duplex sonography (TCDS) is 90% effective in distinguishing between ischemic and hemorrhagic strokes under emergency treatment conditions. TCDS can accurately diagnose stroke type in most cases, making it a fast and reliable option for acute stroke treatment.
A recent study by American Heart Association found that risk of stroke after heart attack is highest within five days. The research highlights atrial fibrillation and ST elevation as key factors increasing likelihood of a heart attack-related stroke.
