enteric

This source of methane is technically known as enteric fermentation.

Raymond noted that other climate solutions are emerging that target enteric fermentation; these include animal feed additives like seaweed, which can reduce cattle's methane production.

"We found that the opioid signaling pathway is required for the developmental formation of nerves in the gut, an understudied part of the body called the enteric nervous system," Uribe said.

"When these receptors were deactivated, the migration and maturation of enteric neurons along the gut were disrupted," Uribe said.

"Our finding is incredible and opens up a whole new avenue of enteric neurodevelopmental biology research in the field," Moreno Campos said.
