With science in the headlines amid the Covid-19 pandemic, researchers around the world are looking at the possibility that a focus on extracellular RNA can offer a non-invasive alternative for early diagnosis of cancer and other serious illnesses.

One of those in the vanguard of the effort is Uruguayan molecular biologist Juan Pablo Tosar, who confesses to a long-standing fascination with RNA.

Scientists long thought that RNA, whose main function is turning genetic code (DNA) into specific instructions for assembling proteins, could be found only inside cells.
