The RNA world hypothesis posits that molecules made up of ribonucleic acids (RNA) are responsible for kickstarting evolution ...

Northwestern Medicine scientists have uncovered an unexpected role for a well-known cancer-related protein, revealing a new layer of genetic regulation that could reshape how certain cancers are ...

Ribosomal RNA (rRNA), made from many copies of ribosomal DNA (rDNA), is the core component that powers ...

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 ...

Scientists have long known that our skin is home to vast communities of bacteria, fungi and viruses. But knowing which microbes are present only tells part of the story. What matters just as much is ...

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 ...

The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...

Myotonic dystrophy type 1 (DM1) is the most common cause of adult-onset muscular dystrophy, a genetic disorder that leads to ...
