Some nuggets from this week in blogland

• The NY Times reports researchers have found “three distinct ecosystems” or enterotypes in human gut bacteria, a potentially groundbreaking discovery for medicine.
• Tree of Life touches on a Times editorial about hospital acquired infections, suggesting funds for study be devoted to the “microbial ecology of hospitals”.
• John Dupuis of Confessions of a Science Librarian  links this week to a review of search tools called Pubmed and beyond: a survey of web tools for searching biomedical literature. 
• Dupuis also links to this discussion of social media use (or the lack thereof) by scientists, and Krafty Librarian weighs in as well.
