Evolution of gut bacteria tracks splits in primate species
Primates and microbes have been splitting in sync for at least 10 million years.
- Genetics
Swapping analogous genes no problem among species
Many genes are interchangeable between yeast, bacteria, plants and humans.
- Genetics
Herbicide no match for fruit flies’ gut microbes
Friendly gut bacteria team up to break down herbicide that might otherwise harm fruit flies.

Scientists find clue to why mitochondrial DNA comes only from mom
Scientists have identified a protein that chops up the mitochondrial DNA in a dad’s sperm after it fertilizes an egg. The finding helps explain why mitochondrial DNA is usually passed on only by mothers.
