Until now, most evidence for PTSD-like symptoms in ASD has relied on self-reports, leaving the underlying brain mechanisms unclear. In a new study, researchers led by Professor KIM Eunjoon at the Institute for Basic Science (IBS) have uncovered how an ASD-related mutation in the Grin2b gene, which encodes the GluN2B subunit of NMDA receptors, disrupts brain circuits that normally extinguish fear. Their findings, published in Science Advances, provide the first detailed mechanistic explanation for why ASD increases PTSD risk.

Farmers in the Middle East were more committed to wine production over olive growing during times of climatic change in the Bronze and Iron Ages, according to new research.

A survey study of families with puppies in the U.K. has identified multiple mental health challenges alongside benefits of ownership for adults and kids alike, suggesting that a mental health boost should not be the main motivator behind getting a puppy. Rowena Packer of the Royal Veterinary College, U.K., and colleagues present these findings in the open-access journal PLOS One on September 17, 2025.
