Study explores attitudes and beliefs about HPV

A study exploring attitudes and beliefs about HPV found low awareness and a stigma associated with the disease, which hinders public acceptance of the vaccine. The research suggests that health education efforts should take a public-health approach to emphasize the prevalence and commonality of HPV infection among sexually active adults.

A higher physical activity level slows lung function decline in smokers

A large retrospective cohort study found that moderate to high levels of regular physical activity slow lung function decline among smokers and reduce the risk of developing chronic obstructive pulmonary disease (COPD). Regular exercise suppresses inflammatory markers in the lungs caused by smoking, reducing COPD pathogenesis.

Size of brain areas does matter -- but bigger isn't necessarily better

Researchers at the Salk Institute found that brain area sizes must be optimally tuned to perform tasks, with underperforming mice exhibiting reduced tactile and motor behaviors. Genetic manipulation in mice revealed a correlation between area size and performance, which was reversed by genetic rescue experiments.
