Wanna know how Sylar pulled off his "playing dead" trick? Remember the Cockroach last week?
from Wikipedia:
"Cockroaches are mainly nocturnal and will run away when exposed to light. A peculiar exception is the Oriental cockroach, which is attracted to light, thus making it a far more annoying pest.
The cockroach is also one of the hardiest insects on the planet, capable of
living for a month without food. It can also hold its breath for 45 minutes and has the ability to slow down its heart rate.
It is popularly suggested that cockroaches will "inherit the earth" if humanity destroys itself in a nuclear war. Cockroaches do indeed have a much higher radiation resistance than vertebrates, with the lethal dose perhaps 6 to 15 times that for humans. However, they are not exceptionally radiation-resistant compared to other insects, such as the fruit fly.
The cockroach's ability to withstand radiation better than human beings can be explained in terms of the cell cycle. Cells are more vulnerable to effects of radiation when they are dividing. A cockroach's cells only divide once when in its molting cycle, which at most happens weekly. The cells of the cockroach take roughly 48 hours to complete a molting cycle, which would give time enough for radiation to affect it but not all cockroaches would be molting at the same time. This would mean some would be unaffected by the radiation and thus survive."
Found this on the Heroes MB this morning....interesting theory that makes sense whether it's accurate or not.
