Researchers at Cornell University have developed tiny polymer pellets containing NGF that can regenerate dying cells and improve cognitive function in rats. The system targets specific brain areas and releases NGF molecules over a period of months, offering potential for a one-time treatment for Alzheimer's.
Scientists estimate a small amount of life could have existed on Mars through chemical reactions over billions of years. They also explore the possibility of life on Europa, estimating lower energy availability than on Mars.
Scientists have discovered a cheap material that changes color in response to light, potentially revolutionizing energy-efficient windows. The material could regulate illumination levels, glare, heat gain and loss, making buildings use less energy.
Despite high levels of mercury found in the Seychelles, a nine-year study found that frequent consumption of commercially sold fish carries no ill effects from low levels of mercury. The study suggests that current regulations in the US are sufficient to safeguard frequent fish eaters against mercury exposure.
A recent Penn State study found that new welfare reform legislation and abortion restrictions may have created a paradoxical outcome. The increase in single mothers, who are often on welfare, may be due to the decreased access to abortion services, leading more women to choose childbearing over termination.
A new study reveals that religious grandparents develop and maintain stronger relationships with their grandchildren compared to non-religious grandparents. The research found that religious observance is associated with greater involvement in family and social ties, which may be a key factor in grandparent-grandchild relationships.
Researchers at Penn develop groundbreaking new brain tracer Trodat to evaluate brain function in normal and disease states. The imaging agent, derived from tropane, follows the flow of dopamine in the brain and can be used as a diagnostic tool for imaging dopamine transporters.
