ONLINE COVER Animation of human lungs breathing in a 37° chamber. Lungs removed from donors for transplantation are often damaged but can be treated in the controlled environment of this transparent dome to improve their health. Gene therapy with interleukin-10 increases the chances that the lungs can be successfully transplanted into a recipient. See Cypel et al. in this issue. [Credit: Chris Bickel, AAAS]
