Transposons could be rewiring our brains

A new study by neuroscientists at the University of Oxford shows that mobile genetic elements that were active in the genomes of our ancestors could be closely linked to important functions in our brain and might help diversify ...

Adult astrocytes are key to learning and memory

Researchers at Baylor College of Medicine reveal that astrocytes, the most abundant cells in the brain, play a direct role in the regulation of neuronal circuits involved in learning and memory. The findings appear in the ...

Switching brain circuits on and off without surgery

In the maze of our brains, there are various pathways by which neural signals travel. These pathways can go awry in patients with neurological and psychiatric diseases and disorders, such as epilepsy, Parkinson's, and obsessive-compulsive ...

A new genetic marker for schizophrenia

Schizophrenia is a complicated disease that often appears in early adulthood. Although scientists have not traced the genetic causes, more than 80% of schizophrenia cases are considered to have a hereditary cause. In a new ...

Scientists transform lower-body cells into facial cartilage

Caltech scientists have converted cells of the lower-body region into facial tissue that makes cartilage, in new experiments using bird embryos. The researchers discovered a "gene circuit," composed of just three genes, that ...
