How to overcome the hygiene issues of prehensile mouthparts?

Most animals do a lot more handling of items with their mouths than we do, because the human quirk of having kept two limbs aside for non-locomotive activities is pretty unusual. So overall you are ...

Could hypothetical cells use liquid Carbon Tetrafluoride as an alternative solvent to water?

I think carbon tetrafluoride lacks some of the useful properties of water to be a good substitute: it's non polar, thus it will have problems dissolving ionic substances and acting as a buffer for ...

Could stromatolite formation be significantly speeded up?

They get help: Stromatolites thrived on the early Earth, and perhaps you need conditions that are more conducive to them. But If you really want to accelerate their growth, take away the heavy ...

Could hypothetical cells use liquid Carbon Tetrafluoride as an alternative solvent to water?

That's a very solid "maybe". Non-polar? Well, the chemistry won't be the same as we have in water, but that wasn't gonna happen anyway. Plenty of sci-fi writers and actual scientists have ...

How to create realistic alien evolution in a swampy planet? (Like dagobah from Star Wars)

Honestly, roaches, kind of like District 9. They would be intelligent enough and have many usable limbs. This question is kind of vague so almost anything can work here, even a blob-person.
