A recent study from Family Relations reveals that parents in low-income environments are more prone to depression when they lack social support. This is particularly true in rural regions where mental health resources may be scarce. Social support mechanisms can help mitigate negative thinking and promote healthy parental practices.

Hale III, found that these two conditions have different symptoms and characteristics, contrary to current classification in the DSM-V.
An international body of earth scientists has agreed to move the Quaternary age boundary by 800,000 years, formalizing a natural event marking the start of global climate cooling. This decision ends decades of controversy and provides a fixed point for geological research.
Research shows consumers develop specific rules for sharing personal data online, influencing retailers' data mining practices. Understanding these rules is crucial to improving online experiences and products.
Firms in energy-intensive industries invest regardless of regulatory enforcement due to social pressure and internal synergies. Economic logic also plays a role, as firms that expect to reap early benefits or recognize internal synergies are more likely to invest sooner.
Researchers found that scientists combine model-based cognitive problem-solving with creativity to develop a better understanding of the system under investigation. This approach allows scientists to build real-world models and make predictions, leading to novel problem solutions.
