From Fractured Genomes to Broken Minds

The discovery of genetic copy-number variants and growing data on their links to mental disorders suggest new paths of investigation and new targets for therapies.

DNA Repair System Implicated in Brain Disorders, Too

DNA damage and repair are widely studied by cancer biologists and immunologists; now neuroscientists are taking a look

Lightning Strikes Twice

A Nobel Prize-winning neurologist/biochemist has transmitted a Parkinson's-like disease from the involved brain to a mouse model.

Unraveling the Complexity of Schizophrenia Genetics

Our understanding of the biological mechanisms of schizophrenia risk has steadily evolved over the past few decades, attributable largely to advances in human genetics and to genomic technologies. One of our series of Reports on Progress.

How Should We Be Thinking About Genetic Studies?

As the behavioral genetics field grows, we must be cautious not to oversimplify the research, warn experts, particularly in studies linking single genes to certain traits.

Tweaking Genes to Target a Form of Alzheimer’s

Researchers develop genetic “structure corrector” that unfolds misfolded protein apoE4 in mice into shape of its helpful sibling, apoE3. If it works in people, that protein change might improve healing for a range of brain injuries.
