Harvard study suggests asteroids might play key role in spreading life

Scientists at the Institute for Theory and Computation have made a comprehensive calculation suggesting that panspermia could happen, and have found that as many as 10 trillion asteroid-sized objects might exist that carry life.

Inosine could be a potential route to the first RNA, Harvard study says

In a paper published in PNAS, Jack W. Szostak, professor of chemistry and chemical biology at Harvard, along with graduate student Seohyun (Chris) Kim, suggest that RNA could have started with a different set of nucleotide bases. In place of guanine, RNA could have relied on a surrogate, inosine.
