A nationwide study found that unwed mothers face poorer health at midlife than women who have children after marriage. The study suggests that single motherhood has long-term negative health consequences, and government efforts to promote marriage may not address these issues.
Researchers found that college students were more likely to talk about sexual health issues with their partners after watching a Sex and the City episode featuring Samantha and Miranda. The study showed that viewers modeled their behavior after the TV characters, having these conversations in their own lives. Almost half of participant...
Two of Greenland's largest glaciers have lost sufficient ice to equal 300 gigatons in the last decade, equivalent to seven years of normal snow accumulation. Meanwhile, Helheim glacier gained a small amount of mass over the same period, providing a high-definition picture of climate-caused changes on the island.

This study offers insights into the structure of Hawaiian society during this tim...
Researchers found that implementing a tobacco-free policy at an Ohio women's substance abuse treatment center led to a 28 percentage point decrease in program completion rates. The study suggests that smoking bans may pose challenges for treatment centers, but they are not a reason to abandon tobacco-free policies entirely.
Research finds that women with heart failure who suppress their emotions tend to have higher symptoms of depression and anxiety, even with knowledge about their illness. This suggests that clinicians should consider individual coping styles when educating patients about their condition.
A study published in the Journal of Neuroscience reveals that social stress can increase inflammation among brain cells, leading to anxiety-like behaviors. The researchers found that immune cells migrated to the brain in response to social stress, triggering an inflammatory response and a specific activation pattern of neurons.
Female mosquitoes produce heat shock proteins to protect themselves from stress caused by hot blood meals, helping them digest the meal and maintain egg production. Tests on other insects also showed a similar response.

The study found that antibiotics can reduce this effect, highlighting the role of gut bacteria in modulating stress-induced immune responses.
A study found that media exposure to idealized body shapes improves women's body satisfaction, at least initially. However, this effect is often accompanied by increased dieting behavior and ultimately unsustainable body image.
A recent study suggests that breast cancer patients experiencing persistent fatigue may have an imbalance in their autonomic nervous system, leading to accelerated aging. Researchers found that fatigued patients showed higher levels of stress hormones and lower parasympathetic activity compared to non-fatigued patients.
A new study found that employee mood affects perceptions of customers and work quality, with positive moods linked to greater verbal fluency and reduced errors. Employees in a bad mood tend to answer fewer calls, need more breaks, and perform less well, while positive customers can help improve their mood.
