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 ...

Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown ...

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 ...

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 ...

Major depression is not only a crisis of mood, it is also a crisis of biology that reshapes the brain itself. As genetic tools sharpen, scientists are now tracing how inherited risk for depression is ...
