The mechanism of the flow of genetic information from the DNA molecule to microRNA molecules and from there to proteins. The identical genetic information is stored in the DNA of all cells in our body. This situation requires precise regulation of gene activity so that only the correct set of genes is active in each type of cell. Courtesy of the Nobel Prize Committee

The two scientists were recognized for their contribution to the understanding of genetic regulatory mechanisms through the discovery of microRNAs - tiny RNA molecules that play an essential role in the processes of development and function in cells

Colonies of ants began growing mushrooms when an asteroid hit Earth 66 million years ago. This damage caused mass extinction but also created ideal conditions for fungi to flourish. This is how an evolutionary partnership was created that became even closer 27 million years ago and continues to this day. Credit: Don Parsons

Ant farming began 66 million years ago following the asteroid that doomed the dinosaurs

Smithsonian Institution scientists compiled and analyzed an extensive genetic database, and found that some mushroom crops became completely dependent on ants 27 million years ago, a process created 65 million years ago by an event

The discovery of SN H0pe, a distant supernova that was observed in three replicates using gravitational insolation, allowed researchers to accurately measure the Hubble constant at different times, revealing insights into the expansion rate of the universe
