Several genes implicated in food digestion have been deleted or inactivated in platypus. This loss perhaps explains the anatomical and physiological differences in the gastrointestinal tract between monotremes and other vertebrates and provides insights into platypus genome evolution.
Increasing resources to Pseudomonas bacteria boosts cooperative behavior, such as biofilm production or siderophore formation, because the costs of cooperation decrease, confirming experimentally that resource supply is an important factor in the evolution of cooperation.
Analysis of gene expression in male elderly and young human wounds suggests that estrogen has a more profound influence on aging than previously thought.
The use of ultraviolet light-sensitive markers reveals that the toilets of patients with Clostridium difficile diarrhea are cleaned less well than other patients; and that the C. difficile persists on the toilet even after adequate cleaning.
