Common human viruses threaten endangered great apes

A study found that common human viruses, such as HRSV and HMPV, are responsible for outbreaks of respiratory disease in wild chimpanzees. The researchers suggest that minimizing human contact and implementing guidelines to reduce the risk of disease transmission can help protect great apes.

Environmental pollution and diabetes may be linked

Scientists at the University of Cambridge highlight a strong correlation between persistent organic pollutants (POPs) and insulin resistance, leading to adult-onset diabetes. Research suggests that individuals with high POPs levels in their blood are more at risk of developing type 2 diabetes, even if they are thin.

Hungry mothers risk addiction in their adult children

Research suggests that babies conceived during a period of famine are at increased risk of developing addictions later in life. The study, which examined the 1944-45 Dutch 'hunger winter,' found that pregnant women who experienced severe food shortages were more likely to have children with addictive disorders.
