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 ...

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 ...

Scientists have identified an RNA-based sperm aging clock driven by rsRNA length changes, which may help assess paternal reproductive risk and offspring health.

RNA therapeutics target translation rather than DNA, aiming to correct shared protein production errors. By enabling cells to read through premature stop codons, engineered tRNAs could restore ...

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 ...
