MicroRNAs, whose discovery was recognized with the 2025 Nobel Prize in Physiology or Medicine, are central regulators of gene expression, yet a fundamental question has remained unanswered: how cells ...

MicroRNAs are short RNA sequences that maintain a tight control on which genes are expressed and when. They do this by regulating which messenger RNA (mRNA) transcripts—the single-stranded templates ...

Abnormal formation and growth of the placenta is considered an underlying cause of various pregnancy complications such as miscarriages, preeclampsia and fetal growth restriction. Yet, much remains to ...

Many diseases are caused by a missing or defective copy of a single gene. For decades, scientists have been working on gene therapy treatments that could cure such diseases by delivering a new copy of ...

Victor Ambros, a developmental biologist at the University of Massachusetts Chan Medical School, and Gary Ruvkun, a geneticist at Harvard Medical School, won this year’s Nobel Prize in Physiology or ...

MicroRNAs can make plants more capable of withstanding drought, salinity, pathogens and more. However, in a recent study scientists showed just how much we didn't know about the intricate processes ...

The 2024 Nobel Prize in physiology or medicine goes to Victor Ambros and Gary Ruvkun for their discovery of microRNA, tiny biological molecules that tell the cells in your body what kind of cell to be ...

The Earth formed 4.5 billion years ago, and life less than a billion years after that. Although life as we know it is dependent on four major macromolecules – DNA, RNA, proteins and lipids – only one ...
