A bioengineered protein may someday treat carbon monoxide poisoning

Mice that received the treatment eliminated carbon monoxide from the body in their pee

A white carbon monoxide monitor is shown mounted on a dark brown wall. The alarm has a large white button to "test/reset" on the left. To the right of the button are two round indicators for "power" and "alarm"

Carbon monoxide, an odorless, colorless gas, can be deadly. A study in mice suggests that a bioengineered protein could one day help people get fast treatment.
