Synthetic dyes in industrial wastewater can threaten aquatic ecosystems and human health. Researchers at Doshisha University, Japan, developed a green, single-step co-pyrolysis method that converts bullrush agricultural waste into a zero-valent copper nanoparticle-enhanced bullrush activated carbon (ZVCu@BAC) composite. The material removed both cationic and anionic dyes in laboratory tests, while its preliminary production cost of ~¥1,800 JPY/kg and regeneration performance highlight its potential for sustainable wastewater treatment.
Osaka Metropolitan University researchers found that participation in community gathering places was associated with lower long-term care costs among older adults requiring support or exhibiting mild functional decline.
The prevalence of chronic heart failure, affecting 6.7 million U.S. adults, is expected to increase. Despite rapid advance in therapeutics, chronic heart failure continues to have a high rate of morbidity and mortality. In recent years, the gut microbiome has emerged as a promising new frontier for understanding health and disease.
Being made to feel different, lesser, or unwanted can be a common experience for many minority groups. When people are excluded or denied full social acceptance because they are perceived as having a “lesser” status or value, they can often internalise these beliefs, or stigma. Researchers at Xi'an Jiaotong-Liverpool University (XJTLU) investigated this internalisation, known as self-stigma, among university students. They found that, over time, students with higher levels of mindfulness had lower self-stigma and fewer depressive symptoms.
