A letter to the journal Nature issued an interesting complaint. The Nobel Prize for Physiology/Medicine went to Andrew Fire and Craig Mello this year. Fire and Mello, researchers who study the nematode C. elegans, won the prize for discovering the mechanisms of RNAi – a method of gene regulation in plant and animal cells. The authors of the letter point out that much of the groundwork in understanding RNAi was done by plant scientists. A good point. Not that GS is biased.
