Feeding RNAs to a molecular shredder: Scientists unravel the structure of a regulatory protein complex in RNA disposal

	Feeding RNAs to a molecular shredder: Scientists unravel the structure of a regulatory protein complex in RNA disposal Any errors that occur during the synthesis of RNA molecules or unwanted accumulation of RNAs can be harmful for the cell. The elimination of defective RNAs or of RNAs that are no longer needed is therefore a key step in the metabolism of a cell.

Many laboratory studies have shown that pesticides can harm organisms which they were not meant to affect. Intensive farming is also linked to collapsing populations of wild animals and the endangerment of species such as amphibians. Can the biochemical effects of pesticides upset entire ecosystems?
