Do you really think that it's appropriate for a small group of biologists
to usurp the common meaning of a term?  Science is about creating clarity,
not confusion.  I, for one, refuse to perpetuate these lingual inaccuracies.

If a publication (or post) is meant for general consumption, the onus is
on the writer to communicate in a clear and unambiguous manner.  The care
with which, for example, Alberts et al have written Molecular Biology of 
The Cell (P750-751) illustrates the point:

  When they talk about cell senescence they call it CELL senescence.

  When they talk of continued proliferation potential they enclose 
  "immortal" in quotation marks to indicate its unusual usage.

Many cell biologists could learn a lesson from this.  Let's put this 
issue to bed and do our best from now on to maintain the integrity of the 
language.
