A newly revealed “aging cliff” in sperm RNA marks a conserved molecular transition from youth to later life, offering fresh insight into how a father’s age may influence the earliest stages of ...

Despite being made from a relatively simple set of building blocks, ribonucleic acid (RNA) has a broad array of complex responsibilities. From providing structure to carrying the instructions for ...

Researchers have catalogued thousands of sites in the brain where RNA is modified throughout the human lifespan in a process known as adenosine-to-inosine (A-to-I) editing, offering important new ...

Molecular complexity: RNA-binding proteins may drive advanced brain functions without increasing gene numbers. Life experience impact: Enriched environments in youth activate AP-1, strengthening ...

More than four billion years ago, Earth was a very different place. Pools of water froze and thawed in cycles, minerals shaped reactions, and molecules bumped into each other by chance. Out of this ...

Long known as a messenger within cells, RNA is increasingly seen as life’s molecular communication system — even between organisms widely separated by evolution. For a molecule of RNA, the world is a ...

For decades, circular RNA was treated as little more than molecular background noise — stable fragments that accumulated in ...

DNA and RNA are the molecular blueprints of life, each with unique structures and roles. DNA’s double-helix stability makes it ideal for long-term genetic storage, while RNA’s versatility powers ...

Scientists have demonstrated that cephalopods have an expanded number of microRNA families, which could explain how the complex octopus brain developed. Octopuses and other coleoid cephalopods are ...
