Obsessive-compulsive disorder is a complex, heterogeneous neurobiological condition driven by structural, genetic, and neurochemical dysregulation, defined by the presence of intrusive, ego-dystonic obsessions and repetitive, time-consuming compulsions.

Endogenous Retroviruses (ERVs) are the fossilized genetic remnants of ancient infectious viruses that successfully invaded the mammalian germline tens of millions of years ago. Comprising roughly five to eight percent of the human genome, these elements exist as a latent virome that provides critical evolutionary functions while posing significant pathological risks if reactivated.

Researchers have identified a novel cluster of liver cells (hepatocytes) that specifically emerge during metabolic dysfunction-associated steatohepatitis (MASH). These cells exhibit unique gene expression and cellular senescence, acting as a critical regulator of liver disease progression.

Ocular coloboma is a congenital eye defect that occurs when the optic fissure fails to close properly during early development. Recent research utilizing lab-grown, miniature human retinas—known as retinal organoids—has identified how mutations in a specific growth-controlling protein contribute to this condition.
