The study suggests that personality traits, particularly neuroticism, play a role in shaping mental health responses to large-scale societal stressors.
A new study found that people with Parkinson's disease who engage in higher levels of physical activity experience slower declines in cognitive and motor symptoms. The study, published in Neurology, suggests that physical activity may have dual benefits, with associations with slower cognitive decline and worsening of movement symptoms.
A study published in Neurology found that nearly one-third of people with epilepsy who took certain medications and hormonal contraceptives experienced reduced contraceptive effectiveness. The study highlights the need for greater awareness of interactions between enzyme-inducing antiseizure medications and hormonal contraceptives.
The Nurses' Health Studies have provided a unique opportunity to prospectively follow large populations of women over decades, studying the impact of diet, lifestyle, and other factors on health. The studies have generated evidence that has shaped clinical guidelines and public health recommendations, with findings supporting recommend...
Researchers found nearly one-third of people prescribed hormonal contraceptives were also prescribed antiseizure medications that can reduce contraceptive effectiveness. The study suggests many people may be prescribed combination medications that could decrease hormonal contraceptive effectiveness and increase the risk of unintended p...
Researchers from Rutgers University have discovered that some mosasaurs were built for surprise attacks, with a longer, flexible tail section allowing for faster lunge speeds. This suggests that these ancient sea predators were better suited to ambush hunting in shallow seas.
The project analyzes the feasibility of Payment for Ecosystem Services (PES) schemes to protect water resources and strengthen city resilience. It compares Barcelona and Melbourne's water governance models to provide insight into the design and success of economic incentives for conserving urban ecosystems.
