Stanford researchers have created a CRISPR-based technology to target RNA in neurons, enabling repair processes for genetic diseases. The method addresses key challenges in Cas9 delivery and DNA repair. It reveals unique genome editing rules in neurons, paving the way for targeted therapies.

Study overturns idea that light drinking protects brain health

A large-scale study combining observational and genetic data has found that any alcohol consumption increases dementia risk, with no safe level identified. Published in BMJ Evidence Based Medicine, the research challenges previous beliefs about moderate drinking's benefits. Dementia risk rises linearly with alcohol intake, according to the analysis.

Evolution of human intelligence linked to mental illness vulnerability

Researchers have traced genetic variants in the human genome to reveal that advances in cognitive abilities around 500,000 years ago were soon followed by mutations increasing susceptibility to psychiatric disorders. This suggests a trade-off in brain evolution. The study, published in Cerebral Cortex, analyzed 33,000 genetic variants to build an evolutionary timeline of brain-related traits.
