Their findings showed the mice with microbes from large-brain primate species produced and used more energy, while those with microbes from the small-brain species stored more energy as fat.

The study, conducted in a mouse model of lung cancer, was published in Nature on December 4.

They observed that the mice had improved neurological outcomes.

The researchers found that stress changes activity in a brain circuit in mice, and these changes distinguish the mice that will recover from the ones that won't.

This lower dose still led to harmful effects in the brains of mice, even after exposure ceased for months.
