Previous studies that suggested that lens-wearing may affect eye growth are supported now by primate studies, which raises questions about the use of eyeglasses in children (pages 761–765).
Even though diagnosis of prostate cancer can be made earlier than in the past, prognosis is still difficult. The discovery of new metastatic markers should aid in treatment design.
The molecular and neural bases for pain have proven elusive, but new studies approach an explanation from different directions (pages 766–773 and pages 774–780).
The importahce of preserving biodiversity extends beyond the discovery of new drugs to understanding how other species have dealt with medical problems we currently face.
Technological miniaturization combined with the power of molecular genetics makes the mouse a model animal for understanding human cardiovascular and pulmonary diseases.
A mathematical approach to the transmission dynamics of tuberculosis offers a new understanding of past epidemics and suggests future interventions (pages 815–821).
