"Here we report the detection of uracil, one of the four nucleobases in ribonucleic acid, in aqueous extracts from Ryugu samples. In addition, nicotinic acid (niacin, a B3 vitamer), its derivatives, and imidazoles were detected in search for nitrogen heterocyclic molecules."
This is an important step in detecting life and also it's origins in the universe.

Uracil in the carbonaceous asteroid (162173) Ryugu - Nature Communications
Uracil was identified in the sample returned from the asteroid Ryugu. Having been provided to the early Earth as a component in such asteroidal materials, these molecules might have played a role for prebiotic chemical evolution on the early Earth

RNA molecule uracil found in asteroid Ryugu samples
Researchers have analyzed samples of the asteroid Ryugu collected by the Japanese Space Agency's Hayabusa2 spacecraft and found uracil, one of the informational units that make up RNA, the molecules that contain the instructions for how to build and operate living organisms. Nicotinic acid, also known as Vitamin B3 or niacin, which is an important cofactor for metabolism in living organisms, was also detected in the same samples.
