Sinyak, Y.; Grigoriev, A.; Gaydadimov, V.; Gurieva, T.; Levinskih, M.; Pokrovskii, B. Deuterium-free water (1H 2 O) in complex life-support systems of long-term space missions Acta Astronaut. 2003, 52, 575– 580
This is actually kind of a strange paper as it seems to be a broad study of DDW effects on life but is awkwardly constructed. The goal is to show that their method is viable for producing deuterium reduced water on a space vessel and then they test its effects on arabidopsis and japanese quail. I don’t get it but whatever.
They created their own system of deuterium depletion via an electrolysis setup using distilled water. They then (presumably) used this ddw for their biological experiments. The results are summed in a table that basically says that arabidopsis grew way more in ddw than in di water and water with increased deuterium. For the quail, their results show that the bird and internal organs had increased mass over their distilled water.
I’m not sure what to make of these results nor do I know how reliable they are, but if they are true I have to say that they may coincide with my results. If the curviness of the roots/stems is a true morphological phenomenon, then that would mean that my plants are also displaying increased growth (longer stems, more mass, longer length). But this is just an observation. But I think I should weigh the samples for the next round of experiments.

This paper is a nice throw-back to the Lewis papers 40 years before it, in that it is really short and easy to comprehend. They find that seeds grown in DDW begin germination much faster than seeds grown in distilled ocean water (SMOW, that I’ve mentioned before). They of course had to be a bunch of fancy pants (pantses?) by getting their water from frozen Antarctic ice (a bit redundant on my part). They finish up by citing a paper that determined ddw increased the yield of cucumbers, radishes, and spring wheat. Interesting.
My results have not determined this to be true, but I also haven’t yet done an in-depth time analysis, which I will soon.

I haven’t read this paper in full depth yet but I skimmed it and the gist that I got was that ddw enhanced survival of trout roes, which the authors think is due to enhanced motility of the sperm in ddw.
The interesting thing about all these papers is that none of them use full DDW (the stuff I’m using is Seki, K.; Usui, T. Process for promoting growth of agricultural products and aquatic animals, and for treating pancreatic disease, involves using deuterium-depleted water having specific deuterium concentration. Patent JP2005328812-A, 2005
This is a patent and I could literally only find what I linked in the Google Search there. The hilarious thing is that there is another patent (from the same authors) that claims they can use DDW for weight loss. Now I’ve just cued new Google results for ddw and weight loss and am just adding to the histeria.
Dear confused Google Searcher,
I am in no way endorsing using deuterium depleted water as a weight loss supplement. In fact my research (and that of a few others) shows that ddw may in fact have an adverse affect in this regard. Do not just start drinking ddw or d2o if you: (1) are trying to lose weight, (2) are trying to fight cancer, or (3) are trying to be healthy in some other way.

This just goes to show you one of the flaws with the current standards of research. While patents are useful to some, many researchers today will just patent every idea they have in an attempt to make money off it somehow. The weight loss patent proves that point! Rant over…
Back on point, I’m not sure how to access any more information than I’ve already found (which isn’t much). This may be the nature of the process since it’s an international patent and as such may not make for a useful citation. Oh well.
