RNA reactor could have served as a precursor of life
(PhysOrg.com) -- Nobody knows quite how life originated on Earth, but most scientists agree that living cells did not abruptly appear from nonliving cells in a single step. Instead, there were probably a series ...

The language of RNA decoded: Study reveals new function for pseudogenes and noncoding RNAs
The central dogma of molecular biology, as proposed in 1970 by Francis Crick and James Watson, holds that genetic information is transferred from DNA to functional proteins by way of messenger RNA (mRNA). This suggests that ...

We are not only eating 'materials', we are also eating 'information'
In a new study, Chen-Yu Zhang's group at Nanjing university present a rather striking finding that plant miRNAs could make into the host blood and tissues via the route of food-intake. Moreover, once inside the host, they ...
