Discover how CRISPR genome editing is revolutionizing medicine. Learn the science of Cas9, current clinical trials, and the future of gene editing.

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 ...

RNA is one of the bodies most vital molecules, and it comes in a few forms. For example, messenger RNA fills an essential role in gene expression by copying the sequences of active genes, which are ...

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 ...

Cells in our bodies produce RNA based on genetic information stored in DNA, and RNA serves as a blueprint for making proteins. Researchers at KAIST have discovered a new phenomenon: Removing "circular ...

One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

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 ...

New research identifies a critical RNA recycling system that prevents cellular "clogging," offering a new path for anti-aging therapies.

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