About the prize

“The said interest shall be divided into five equal parts, which shall be apportioned as follows: /- – -/ one part to the person who shall have made the most important discovery within the domain of physiology or medicine …” (Excerpt from the will of Alfred Nobel)

Alfred Nobel had an active interest in medical research. Through Karolinska Institutet, he came into contact with Swedish physiologist Jöns Johansson around 1890. Johansson worked in Nobel’s laboratory in Sevran, France during a brief period the same year. Physiology or medicine was the third prize area Nobel mentioned in his will.

The Nobel Prize in Physiology or Medicine is awarded by the Nobel Assembly at Karolinska Institutet, Stockholm, Sweden.

Tiny RNAs with profound physiological importance

Victor Ambros and Gary Ruvkun discovered microRNA, a new class of tiny RNA molecules that play a crucial role in gene regulation. Their groundbreaking discovery in the small worm C. elegans revealed a completely new principle of gene regulation. This turned out to be essential for multicellular organisms, including humans. MicroRNAs are proving to be fundamentally important for how organisms develop and function.

The 2024 medicine laureates

The Nobel Assembly at the Karolinska Institutet has decided to award the 2024 Nobel Prize in Physiology or Medicine jointly to Victor Ambros and Gary Ruvkun “for the discovery of microRNA and its role in post-transcriptional gene regulation.”

In 1993, they published unexpected findings describing a new level of gene regulation, which turned out to be highly significant and conserved throughout evolution.
