Discovery of MicroRNA Genetic Regulation Leads American Scientists to Win 2024 Nobel Prize

XTalks

The 2024 Nobel Prize in Physiology or Medicine has been awarded to American scientists Victor Ambros and Gary Ruvkun for their groundbreaking discovery of microRNA (or miRNA) and its role in post-transcriptional gene regulation. Last year’s Nobel Prize in Physiology and Medicine also went to RNA researchers.

Study revealing the secret behind a key cellular process refutes biology textbooks

Scienmag

For the first time, researchers describe how Rho protein really stops gene expression COLUMBUS, Ohio – New research has identified and described a cellular process that, despite what textbooks say, has remained elusive to scientists until now – precisely how the copying of genetic material that, once started, is properly turned off.
