A study reveals that fire-related deaths are a major public-health problem in India, with over 163,000 deaths in 2001, mostly among young women. The authors estimate that these deaths are six times higher than reported by the police and suggest common causes including kitchen accidents, self-immolation, and domestic violence.

A study suggests that childhood sleep problems persisting through adolescence can affect cognitive abilities, particularly executive functioning. Sleep problems during late childhood and early adolescence, such as being overtired or sleeping more than others, were found to be strong predictors of later executive control.

A new study suggests that drinking alcohol in early adulthood may increase the risk of reflux esophagitis (RE) and Barrett's esophagus (BE), while wine consumption may reduce this risk. Higher education levels are also inversely associated with BE risk, suggesting socioeconomic status plays a role in the development of these conditions.

Scientists have discovered a compound called zymosan that can respond to two different receptors in dendritic cells, sending both stimulatory and calming messages. This finding could guide the development of vaccines against infectious agents and potentially boost the immune system's ability to fight chronic infections.
