Very cool stuff from the the @mizrahilab.bsky.social!
Excited to share our new @natecoevo.nature.com
paper. We identified microbes found across nearly all ruminants that act as the functional backbone of both the rumen ecosystem and the host, with major implications for food security and climate change mitigation. (1/8)
