Today was spent learning about prior research in our area:

  • William Chorney, Norbert J. Scully, Henry L. Crespi, and Joseph J. Katz studied algae growth in D2O, in 1959. Even in 99% D2O, the algae eventually would grow.
  • Arthur K. Parpart’s 1935 study of the Permeability of the Mammalian Erythorocyte. D2O penetrates erythorcyte cells about 44% slower than H2O.
  • S.C. Brooks, Osmotic effect of deuterium oxide (heavy water) on living cells. A study showing the dehydrative effects of D2O on a plant (Nitella) leaf. The leaf would shrink with D2O and expand when given H2O. Brooks stated that D2O ‘violently dehydrates living cells,’ and wrote about a mouse that became thirstier the more D2O he drank.
  • Joseph J. Katz, Henry L. Crespi, Dorice M. Czajka, and Asher J. Finkle: Course of deuteriantion and some physiological effects of deuterium on mice.  Interesting that mice drinking water less than 30% D2O could survive for quite a while, however they did not produce any offspring. Also, it seems that it takes longer for D2O to work its way into the brain than it does other organs like the liver and spleen. It’s also worth noting that some of the mice wouldn’t voluntarily drink the D2O, maybe they realized it only made them more thirsty?
