Diets rich in fish oil compared with diets where lard is the predominant fat lead to very different types of bacteria being found in the guts. The bacteria appear to help with the health benefits of fish oil and the harmful effects of lard.

Cats chase mice, mice hide from cats. This is the game played out throughout the places where cats and mice co-exist. New research suggests that mice can be chemically programmed to be controlled by cats.

The hormone leptin, which signals fullness to animals, has been shown to act through neurons. New research suggests that another type of cell is also involves called glia. The finding could have implications for obesity research.
Scientists may have found the brain cells responsible for the varying reactions to stress. The research also suggests that there are variations between animals in how the brain responds to stressful situations.
Mice are effective at transferring disease-causing pathogens to feeding ticks. This can lead to diseases being spread to people. Do the mice mind the ticks? It seems that they may help the mouse live for longer.
Researchers have identified a region of the brain which is sensitive to small changes in memory. The results provide a clue as to why this area is often found to be abnormal in people suffering with schizophrenia.
Mice appear to pass certain fears onto their offspring, according to a new research study. Trials so far on mice suggest that certain smells associated with frightening events can be passed on to successive generations.
