Gut bacteria might alter anxiety and stress-related chemicals in the blood.

There is an amazing amount of research going into gut flora and fauna at the moment!

When a team from the University of Missouri in Columbia transplanted gut bacteria from female Harlan mice into female Jackson mice, the animals became less anxious and had lower levels of stress-related chemicals in their blood.
[Harlan and Jackson are the names of laboratories where the mice came from]. Here's the link to their work.

Is there a future where happy people will be able to pass on their gut bacteria??
