The teeming trillions of bacteria in the digestive tracts of mice have been shown to affect the animals' brain development and behaviour. Mice bred in sterile environments without these "gut flora" were seen to be more adventurous and less anxious than mice with normal gut flora. The research adds weight to the idea that gut bacteria are a critical part of the overall development of mammals...

A study of hailstones has found large numbers of bacteria at their cores. The find lends credence to the "bio-precipitation" idea, which suggests that bacteria are actively involved in stimulating precipitation. The bacteria have protein coatings that cause water to freeze at relatively warm temperatures...
