Victor Ambros and Gary Ruvkun won the Nobel for medicine for their discovery of microRNA.



The Nobel Prize in Medicine was awarded on Monday to two US scientists for discovering microRNA, a previously unknown type of genetic switch which is hoped can pave the way for new medical breakthroughs.

But while several treatments and tests are under development using microRNAs against cancer, heart disease, viruses and other illnesses, none have actually yet reached patients.

And the world paid little attention when the new Nobel laureates Victor Ambros and Gary Ruvkun revealed their discovery decades ago, thinking it was just "something weird about worms", Cambridge University geneticist Eric Miska told AFP.

Here is an explainer about how exactly these tiny genetic switches work inside our bodies.
