The universe expands
Article Abstract:
Ribozymes, or RNA molecules capable of carrying out catalysis, have been proven to catalyse nucleophilic addition and elimination reactions that include carbonyl groups. Moreover, ribozymes' catalytic functions also encompass the formation of peptide bonds as a part of protein synthesis. The announcement of these findings by two research groups, H.F. Noller and colleagues and T.R. Cech and colleagues, greatly increases the scope of catalytic reactions that RNA is known to accomplish.

Radical catalysis
Article Abstract:
A general strategy is described for organocatalysis by using radical intermediates, which are molecules containing reactive single electrons. This new approach has presented many possibilities by permitting the use of reagents that would normally generate allyl anions and it has also marked the beginning of a new aminocatalytic concept.
