Researchers at the University of Illinois have devised a way to modify metal surfaces with self-assembled monolayers of an inorganic compound, called silicotungstate. The resulting films exhibit superior stability and mechanical properties, making them suitable for corrosion inhibition and catalysis.
Studies suggest that slow stop-signal reaction time is responsible for poor impulse control in individuals with ADHD. Researchers are developing an objective diagnostic technique to refine understanding of ADHD and improve diagnosis.
A study of 66 children who stuttered found a strong genetic link to the condition. Most people who stutter have a common genetic factor that contributes to their persistence, with males being more likely to experience persistent stuttering.
A new laser technique called photodynamic therapy appears to prevent further vision loss in people with the wet form of age-related macular degeneration. The treatment uses a red laser light to activate a toxic form of oxygen that stops abnormal blood vessel growth, potentially confining scar tissue and preventing vision loss.
A new study published by the American Heart Association found that immune globulin injections enabled nine out of ten critically ill patients with damaged hearts to recover without heart transplants. The treatment has shown great promise in treating acute cardiomyopathy, a condition affecting up to 50,000 adults each year.
The American Heart Association recommends consuming a variety of fruits, vegetables, and whole-grain products to lower cholesterol. Phytochemicals like sterols, flavonoids, and sulfur-containing compounds inhibit cholesterol absorption.
When marriages fail, homes can exacerbate pre-existing problems, causing severe grief among parents and children. A study found that physical housing environment can be problematic before, during, and after divorce, with concerns about upkeep, maintenance, and money troubles common among custodial parents.
The American Heart Association recommends using oils in their natural state for cooking, and choosing softer margarines over harder ones for spreads. New guidelines suggest that these choices can help lower total fat intake and reduce trans fatty acid consumption.
Researchers found that children's negative beliefs about mothers and peers predict rejection and depression in a multidimensional study of 81 preadolescent children. Non-depressed kids tend to have more positive attributes about their mothers, while depressed kids may experience more stress in their family.
Preliminary tests indicate that years of consuming PCB- and DDE-contaminated fish have had no negative effects on fine motor skills. A comprehensive study is ongoing to examine the effects of environmental contaminants on older people.
A new type of thin-film transistor developed at the University of Illinois can enhance laptop computer displays by increasing switching speeds. The transistor contains a buried channel that allows electrons to move faster, permitting much higher resolutions.
