  • Brain-machine interfaces allow humans—and mice—to interact with onscreen objects.
  • Such interfaces may gain wide applications as they become more capable.
  • Scientists want to better understand how they work, and are exploring how mice operate them.

Scientific Studies Using Mice May Be Hard to Replicate Due to Gut Microbes

Scientists are concerned that the results of studies using mice may be affected by gut bacteria.

Mice in a laboratory

Mice and other rodents are a staple of laboratory research. In fact, mice are the most commonly used vertebrate species. They are popular because you can get them easily and cheaply, they are small, reproduce quickly, share 99% of their genes with humans, and can be utilized to study genetic human diseases. But studies that rely on mice may potentially be difficult to replicate due to the differing gut contents of the rodents.
