comment For which fields are the 1-dimensional algebraic groups known?
So, $K$ should be perfect and algebraically closed to avoid these examples? Probably, this is the answer to the question.

comment Lefschetz on étale fundamental group for quasi-projective varieties
You could be interested in my paper arxiv.org/abs/1203.2595. I will possibly think whether its methods can give an answer to your question. Would a statement like "the morphism of $\pi_1$s is surhective with the kernel being a pro-p-group" (where p is the characteristic of the base field) satisfy you?

comment Is hyperelliptic cryptography “practical”?
Thank you! Actually, I am far from being "practical" myself; yet my opinion on the scientific value of an algorithm (that does not include any theorem as its part) does depend on the existence of an explanation why may this algorithm be "useful" (maybe, in future).

Did you try to read webusers.imj-prg.fr/~bruno.kahn/preprints/1009.1900v1.pdf (or a newer version of this text)?

comment Algebraic K theory, Karoubi completion and splitting
I doubt that any property of pre-triangulated smooth DG categories (that is not valid in some more general context) may be classically known.:) So, could you give a reference?

comment $l$-dependence of the group of homologically zero cycles
Do you have a reference for a conjecture of this sort (in this case)?

comment $l$-dependence of the group of homologically zero cycles
This conjecture is clearly wrong in general: possibly true if the base field is finitely generated (yet I am not sure; I may be false for trivial reasons in this case also).

comment Chow group over function field and algebraic equivalence
If you assume this equality then you can easily run into a certain contradiction. I will try to recall this argument here if nobody else would give an answer.

comment Derived equivalent varieties with differing integral Mukai-Hodge structures?
Probablly you are right. Yet it seems that noncommutative motives may give an answer.

Sorry; "projective in it".

Thank you! I suspected that keywords for my question include "Morita".:)

comment Derived equivalent varieties with differing integral Mukai-Hodge structures?
The non-commutative motive functor does satisfy certain universality property (actuallya, there are several functors with distinct universality properties;)): in theory, this should describe which functors factor through this one.
