Mutations in a gene may stunt lung development in children

Mutations in a gene may cause poor lung development in children, making them more vulnerable to diseases such as chronic obstructive pulmonary disease (COPD) later in life, say researchers at the University of Pittsburgh Graduate School of Public Health and the German Research Center for Environmental Health.

Exposure to second-hand smoke and alcohol significantly raises the risk of liver disease

The finding adds to mounting evidence that tobacco smoke and alcohol are worse for health as a combination, beyond the individual exposure risks, said Shannon Bailey, Ph.D., an associate professor in the UAB Department of Environmental Health Sciences and a co-lead author on the study.
