• This week, at Nothing in Biology Makes Sense! I discuss my latest paper, study in reconstructing evolutionary relationships with genome-wide data.
• And, at the Molecular Ecologist: How human migration has shaped the diversity of our domesticated microbes.
• Yow. Tracking changes in people’s personal microbial communities during a roller-derby.
• Awww. Bees are better able to remember flowers that offer them caffeinated nectar.
• Eek. The CDC’s warnings about antibiotic-resistant bacteria are getting scary.
• Yay! Ambitious plans to genetically engineer a blight-resistant American chestnut are looking promising.
• Oy. Another meteorite, another claim of fossilized extraterrestrial life.
