Off-topic, but very close (on "luminaries and authorities"):

Ukrainian plasterer turned "neurosurgeon-killer"... ...

I found one too. It' s right here. From there:

Uh... well, if it's science, I'll shut up. Yeah, well, it's a women's forum...

Why don't you show me some other, more authoritative material?

The link, of course, is a load of bollocks.

As for living organisms based on silicon, not carbon, science knows only bacteria (I will not give references) which, if I remember correctly, were found near geysers.

 
joo: As for living organisms based on silicon, not carbon, science knows only about bacteria (I will not provide references) which, if my memory serves me correctly, were found near geysers.

Something has been discovered in geysers, but not that much, it seems. There are some bacteria that partially replace phosphorus with arsenic (if I'm not mistaken). But that's not life on arsenic, agree.

I haven't heard anything about silicon-based life. If such had been discovered, it would have been trumpeted in all the Science sections of all the internet media long ago.

I wonder what properties the silicon analogue of C2H5OH - Si2H5OH would have?

No purely silicon life has been found on Earth, but there is a 'hybrid' form of life (along with carbon polymers using silicon) - it is diatomic algae.

Also interesting is this

Now that's closer. It is true that the large amount of phosphorus in our bones does not at all mean that there is phosphorus life inside us.

We could only seriously speak of 'silicon life' in the sense of self-replicating silicon-based molecules (DNA, RNA etc).

You mean how will it affect the human body? - Probably not at all.

So, it should be similar to regular ethyl alcohol - should, in theory, burn well and be a denaturant for silicon-based proteins. :)

Yes, but it's a single celled thing. No bones or shell to speak of. And yet, silicon is transported during fission.
 
Is DNA only found in multicellular organisms?

That's an odd question. To whom?

If it's for me, I didn't say that.

 

Transport of an atypical element in fission does not yet indicate other life. The basis is still carbon-based DNA, no matter how you look at it.

OK, forget it. The [sh]duck from joo didn't go away.
