In an unprecedented new study, researchers have shown neurotransmitters in the human brain are released during the processing of the emotional content of language, providing new insights into how people interpret the significance of words.

The work, conducted by an international team led by Virginia Tech scientists, offers deeper understanding into how language influences human choices and mental health.

Spearheaded by computational neuroscientist Read Montague, a professor of the Fralin Biomedical Research Institute at VTC and director of the institute’s Center for Human Neuroscience Resear...

Molecular clues about the neurotoxic effects of PFAS. A new study has identified 11 genes that may hold the key to understanding the brain’s response to these pervasive chemicals commonly found in everyday items.

Per- and polyfluorinated alkyl substances (PFAS) earn their “forever chemical” moniker by persisting in water, soil and even the human brain.

This unique ability to cross the blood-brain barrier and accumulate in brain tissue makes PFAS particularly concerning, but t...

Mediterranean Diet Linked to Improved Memory via Gut Bacteria Changes

A new Tulane University study suggests the Mediterranean diet’s brain-boosting benefits may work by changing the balance of bacteria in the gut.

In a study published in Gut Microbes Reports, researchers at Tulane University School of Medicine found that subjects following a Mediterranean diet developed distinctly different gut bacteria patterns compared to those eating a typical Western diet. These bacterial changes correlated with better memory and cognitive performance.

“We’ve known that what we eat affects brain function, but this study explores how that could be happening,” said lead author Rebecca Solch-Ottaiano, Ph.D...

Researchers are making strides in improving gene therapies for genetic diseases, particularly chronic kidney disease, using adeno-associated virus, or AAV, vectors. While AAV-based treatments have shown promise, delivering these therapies effectively to the kidneys has remained a challenge—until now.

There are many different types of AAV capsids—the protein shells of virus particles—that have been used to deliver genes to cells, each with unique effects...
