Vincent Racaniello selects several notable posts each week from molecular and cellular biology and virology. He blogs at virology blog.
- Bacteria outnumber cells of the human body by 10 to 1. A survey of 27 sites reveals amazingly diverse microbial communities that are defined by their location on the body.
- Lyme disease is associated with mammals, but birds can also infected by black-legged ticks that carry the pathogen. Birds may play a role in expanding the range of both the Lyme bacterium and its vector.
- Ovaries can only remain ovaries by constantly suppressing their ability to become male. Silence a single gene, and adult ovaries turn into testes.
I’ll be back next Friday with more selections.
