A higher intake of salt - as measured by the concentration of sodium in urine - is associated with an increased likelihood of atopic dermatitis, says a study published in JAMA Dermatology. The researchers used data on the amount of sodium in urine samples from more than 215,000 people in the UK, collected in a previous study. The authors suggest that restricting salt intake "may be a cost-effective and low-risk intervention" for this skin disease. 

A study led by the University of the Balearic Islands proposes a mathematical model to understand quantitatively the impact of ideologies on the coexistence of various languages. The more groups of people with different linguistic preferences mix, the more challenging it becomes for different languages to coexist within the same society, say the authors, whose study is published in the scientific journal Chaos. The team says this model could be useful to design policies aimed at preserving minority languages.
