Researchers found that newborn babies' right ears are more responsive to speech-type stimuli, while their left ears are more responsive to tonal sounds. This suggests that the auditory system develops differently on each side of the brain from birth.
A team of scientists at Los Alamos National Laboratory discovered a way to control defects in superconducting materials, leading to a two-to-five-fold increase in current densities in high magnetic fields. This breakthrough could revolutionize the development of powerful and energy-efficient superconducting electric motors and generators.
A year-long clinical trial found that prasterone improved disease activity, reduced organ damage, and boosted health-related quality of life for women with active lupus. The treatment, which is safe and effective, could offer an alternative to immunosuppressive agents or large doses of glucocorticoids.
A recent study found that genetic variations in the HLA and TNF gene regions are associated with response to treatment in early rheumatoid arthritis patients. Patients with two copies of the shared epitope were four times more likely to achieve significant improvement in disease activity compared to those with one or no copies.
Adults with ADHD experience significant economic losses, including lower household incomes and reduced full-time employment rates. The condition also affects relationships and overall satisfaction with life.
