Yep, this is different. I don't think this study is sufficient to close the door even on genetic material uptake, but it looks like they went through this quite rigorously. Nucleic acids are likely broken down too far during the digestive process (by nucleases) and are absorbed as single nucleotides, or perhaps really not absorbed at all but that seems a waste of carbon.

I will wait for the follow up on this study in a year or two which I suspect will lock the lid on this.
