In a breakthrough study, researchers found that neutrophils in the lungs produce histamine in response to infection, contradicting the long-held assumption that mast cells are the primary source. This discovery has implications for asthma and bronchitis treatments, suggesting antihistamines may be a viable therapeutic option.
A team of researchers at the University of Pennsylvania School of Medicine has identified a molecular spring within the fibrinogen protein, which explains how blood clots can stretch and bend under physical stress. This discovery may lead to the development of treatments for cardiovascular diseases such as stroke and thrombosis.
Researchers sponsored by ONR have made groundbreaking discoveries in graphene and carbon nanotubes, leading to novel electronic devices and sensors. Their work has the potential to revolutionize industries such as electronics and materials science.
Researchers at Brookhaven National Laboratory stabilized platinum electrocatalysts using gold clusters, maintaining stability in accelerated tests. This breakthrough raises promising possibilities for synthesizing improved platinum-based catalysts.
A new study reveals that women who outwardly express anger may be at increased risk of heart disease if they also have certain risk factors such as diabetes, unhealthy levels of fats in the blood, or age. The researchers found that only expressed anger, not just cynicism or hostility, was predictive of coronary artery disease in women.
A 36,000-year-old human skull from South Africa confirms the 'Out of Africa' theory of modern human origins. The fossil provides critical evidence that modern humans migrated out of sub-Saharan Africa around this time.
Researchers found that natural systems can rebound quickly after hurricanes, while human-made infrastructure and ecosystems are more vulnerable. The study also showed that storm characteristics, such as intensity and direction, play a significant role in environmental damage.
A recent study by Vanderbilt University Medical Center researchers found that prenatal cocaine exposure in rabbits causes a long-lasting displacement of dopamine receptors in certain brain cells. This effect alters their ability to function normally and may lead to subtle cognitive impairments, attention deficits, and emotional problems.
A team of Canadian scientists will gather detailed information about the northern lights using a network of Ground-Based Observatories and NASA satellites. The THEMIS mission aims to pinpoint the cause of brilliant explosions in the auroral displays.
