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 ...

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 ...

Ask a friend what DNA is and, chances are, they have a general idea. Seventy years after scientists discovered the two-stranded helix, DNA (deoxyribonucleic acid) is widely understood as the keeper 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 ...

RNA is the molecule that reads the genetic information stored in DNA. It's critical for the proper functioning of cells, and in a new study scientists have discovered a way of tagging RNA with a ...

New research reveals that sunburn may be caused by RNA damage, not DNA, challenging long-held beliefs about UV exposure.

RNA is the molecule that reads the genetic information stored in DNA. It’s critical for the proper functioning of cells, and in a new study published in Nature Communications, University of California ...
