The natural clays in the earth's crust, for instance, tend to adsorb Pu ions from dilute water streams, locking them away from human biopaths.

My secret is out.

Influenza virus furnishes its mRNA with this structure by a cap-snatching mechanism, in which the viral polymerase cleaves host mRNA endonucleolytically 10–13 nucleotides from the 5′ end and utilizes the capped fragment as a primer to synthesize viral transcripts.

This unfortunate accident has upset me. I have a horrible presentiment that something of the kind may happen to me.
