A fundamental question and mystery in developmental biology is how an organ knows to stop growing after reaching a particular size. Organ growth relies on several processes occurring at the cellular level, including cell division and programmed cell death (or apoptosis). en.wikipedia.org/wiki/Hip…
The word "shmoo" is a technical term with different meanings in the fields of electrical engineering, cell biology, socioeconomics, echinoderm biology, and particle physics. In all these cases, the term is a reference to the Shmoo, a cartoon animal from the comic strip Li'l Abner. en.wikipedia.org/wiki/Shm…

One way biological immortality can be attained is by preventing downregulation of the complex Telomerase in somatic cells.

Consistent low levels of ionizing radiation may help cells avoid damage from higher doses of radiation.

Now, I hesitate to submit this at this time, given that things are not completely under wraps at Fukushima-Daiichi yet. On the other hand I won't be on Reddit at all for about 20 hours after I post this, so I figure why not.

Anyways, I have some nuclear operation training (which means the basics on biological response to radiation). The biological response theory U.S. nukes are trained under is the well-accepted "Linear No-Threshold" (LNT) model, which assumes that any exposure to radiation, no matter how small, adds some risk of getting cancer or mutation later in life. Since it is a linear model, it is assumed that receiving e.g. 10 Β΅Sv in 1 month and nothing for a year is equally as bad as 10 Β΅Sv over that year.

Not all nuclear organizations use this model, some (including in France and a United States radiation health physicists society) believe that research shows that there is evidence for a threshold dose, below which no additional risk is shown from radiation. Some believe
