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 ...

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 ...

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 ...

The so-called ticking biological clock has been framed largely as a concern for women. We talk about egg freezing, ovarian reserve, and the ticking timeline of maternal fertility. Meanwhile, the male ...

There are plenty of unanswered questions about the origin of life on Earth. But the research community has largely reached consensus that one of the key steps was the emergence of an RNA molecule that ...

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

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