comment Can botulinum toxin be grown or kept from denaturing in an UNWRAPPED 50 pound hay bale?
It's been a long time since I knew the ins and outs of botulinum toxin, but I do seem to recall that it's pretty resilient. Botulism is pretty distinct as far as symptom progression. I'll see if I can do more research and return.

comment How much vanilla will kill a person?
@Mario - People overdose on alcohol all the time. Now sugar or water... yeah. Wiki says "pure" extract would be about 35% alcohol and at least 100g of beans per gallon. So drinking an entire gallon of the stuff might be lethal for most people who weighed 65kg or less from the Vanilla. There'd be approximately 1.32L of alcohol - or about 1000g, also enough to probably kill somebody who weighed 150kg or less. They'd be killed by the alcohol before the vanilla.

comment Why does low temperature make RuBP, GP and TP concentrations fall in Calvin cycle?
Enzymes don't universally reduce their catalytic ability when the ambient temperature is lower. Some will be affected more than others. You could probably look up the KM values with relation to temperature if you're curious.

@Mario - The LD50 Rat oral for Ethanol is 7g/kg. Surprisingly, the vanillin is deadlier.

comment Why can't intermediate filaments be used as tracks by motor proteins?
Just a guess: the IF doesn't have directionality. It would be like a single-lane, but two-way road.

comment Can nature create codes and specified complexity?
The problem here is: How do you define nature? At what step is something "Natural" as opposed to "Divine"? Is there a difference the further down you go?

comment Why did abiogenesis only happen once?
@ChinmayKanchi - I remember a few years back that some researchers found some (assumed) Archae members that had some surprisingly different inheritable material. Not completely new genetic material, but odd nucleotides IIRC. I haven't heard about it since, so I don't know if it was ever verified.
