Scientific research continues to uncover interesting connections between the gut microbiome and human health, including everything from depression to PTSD to autoimmune disease. Another example of this are the emerging ties between gut health and autism, with an exciting new study demonstrating how boosting microbial diversity via fecal transplants can dramatically reduce its symptoms in the long term.

Military dogs suffer PTSD just like humans

More than 5 percent of the approximately 650 military dogs deployed by American combat forces are developing canine PTSD.

Many soldiers leave the battlefield suffering deeply painful psychological traumas after returning home. And unfortunately, the same pattern of psychic trauma seems to apply for the dogs that help provide essential services for military men and women.

Scientists Able To Erase Mice Memories

Mice Can No Longer Remember Elephants Being Afraid Of Them

Remember those movies that show devices used to erase the mind? Well, now researchers may be one step closer to that process. Scientists have now been able to remove certain memories from mice.

“While memories are great teachers and obviously crucial for survival and adaptation, selectively removing incapacitating memories, such as traumatic war memories or an unwanted fear, could help many people live better lives,” says Dr. Joe Z. Tsien, brain scientist and co-director of the Brain & Behavior Discovery Institute at the Medical College of Georgia School of Medicine. “Our work reveals a molecular mechanism of how that can be done quickly and without doing damage to brain cells.”

Dr. Tsien and his team were able to remove new and old memories by over-expressing a protein critical to brain cell communication just as the memory was recalled.
