First, they synthesized protosteroids called lanosterol, cycloartenol, and 24-methylene cycloartenol in the lab.

In sediments that formed 1.64 billion years ago, they found chemicals that matched the derivatives of lanosterol and cycloartenol.

In July, researchers from UC San Diego reported that lanosterol, a steroid found in the human eye, reversed cataracts in dogs.

But the exact mechanism of how lanosterol manages to disperse the mass of proteins remains unknown.

Ruben Abagyan, co-author of the paper and molecular biologist at UC San Diego, is looking forward to seeing what the lanosterol drops can dissolve next.
