SCP Foundation

I had written this several months back and received good quality feedback on it. After a few months where I tightened up the language and cut back a significant part, I have finally put it out. Not expecting a knockout on a first skip, but I hope its an adequate showing.

Is the "message" instructions for the organic nano-machines? How did we translate the signal? Why are so many words in it similar to English words but a couple of characters off? Is it translated or not? How can you "decode" completely alien language or an organic machine's programming language and get broken English?

Hmmm. This seems to be suffering from the simple case of "too much bad science".
I haven't read it all, I admit, but I'm only here to comment on what irritates me immeasurably while reading this.

I'm aware this is insanely nitpick-y, but there are far more cases than this, and I find it unbearable to read. It just feels like someone has gone to google and searched up, I don't know, what's the metal with the highest melting point (tungsten?). I'm also getting massive vibes of 682-esque extreme destruction measures. Either way, just remember using scientific terminology to be overly-specific wastes time and is only effective if 1) reasonably spaced and 2) true.

Cool science alone isn't enough to sustain an article. I learnt this the hard way myself.

I enjoyed this one. The basic concept of nano machines sent by aliens to destroy us has always terrified me, and its adaption into an organic is a mostly surface level yet nice twist. I think there are a few relatively easy changes you can make to really improve it.

First don't make quite so indestructible. This thing is scary because of how fast it replicates, and how so much of is lurking in a thawing lake. While cold temperatures should still be the most effective way to eliminate it (it's a nice motif), having it be destroyed at relatively high temperatures and pressures that are difficult to produce is enough. Perhaps make it highly resistant to radiation, which is reasonable, and makes it so that on site nukes will not be enough to contain it. Which seems to be the Foundation's favorite fallback measure.

Second the translation feels really off. Either its an alien language we have no clue about, or the Foundation bites the bullet and uses anomalous means to translate the message. If the former no point really in even having a log. If the latter it should come out with a coherent message, even if words are lacking for a direct synonym. They are usually describable.

Also what actions is the Foundation taking to secure the lake? Honestly, testing this on a new site built on the lake seems reasonable given the threat.

All that said I really enjoyed this one.

I like it, and I'm giving it a +1, bit there are a whole bunch of tonal issues, particurally in the addenda. You use 'us' and 'we' quote a bit in there and you should either commit entirely to 3rd person or to 1st person (ie the direct text of the report). This is just an example, and there are quite a few similar issues throughout that really need to e corrected to fix this article.
