The new issue of the Grand Rounds, a medical blog carnival, is hosted at Medical Humanities. I'm inviting you to go and see the blog. There must more than 50 links to some of the best medical- and health-related blog entries this past week, but the compendium itself is almost like a leisure read.

Some of my picks, which I think would also be of interest to you:

• A new diagnostic blood test for detecting non-small-cell lung cancer
• Caffeine as a memory enhancer
• Implications of genetically modifying mosquitoes to control malaria and dengue
• 
  
  I might have missed more. Do visit Medical Humanities and see for yourself.
