Mikhail Shchepinov Could A Glass Of Heavy Water Lengthen Our Lives?

Mikhail Shchepinov, a former Oxford University scientist, says that the modified drink of heavy water protects against dangerous chemicals known as free radicals that are known to contribute to conditions such as cancer, Alzheimer’s and Parkinson’s. It centres on fortifying the body’s tissues and cells against attack and decay caused by free radicals, dangerous chemicals produced when food is turned into energy. He also claims that foods such as steak and eggs could be enriched with the special hydrogen isotope, known as deuterium, raising the possibility of people being able to “eat themselves healthy”. Dr Shchepinov’s theory is based on deuterium, a naturally-occurring isotope, or form of hydrogen, that strengthens the bonds in between and around the body’s cells, making them less vulnerable to attack… [more] & [more] & [more]

  1. Heavy water

    From Wikipedia, the free encyclopedia

    Not to be confused with hard water or tritiated water.

    Heavy water, formally called deuterium oxide or 2H2O or D2O, is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium, (also known as “heavy hydrogen”) rather than the common hydrogen-1 isotope that makes up most of the hydrogen in normal water.[1] Therefore, some or most of the hydrogen atoms in heavy water contain a neutron, causing each hydrogen atom to be about twice as heavy as a normal hydrogen atom (although the weight of the water molecules is not as substantially affected, since about 89% of the molecular weight resides in the unaffected oxygen atom). The increased weight of the hydrogen in the water thus makes it slightly more dense. The colloquial term heavy water is often also used to refer to a highly enriched water mixture that contains mostly deuterium oxide but also contains some ordinary water molecules as well: for instance heavy water used in CANDU reactors is 99.75% enriched by hydrogen atom-fraction, meaning that 99.75% of the hydrogen atoms are of the heavy type. In comparison, in ordinary water, which is the “ordinary water” used for a deuterium standard on Earth, there are only about 156 deuterium atoms per million hydrogen atoms.

    Heavy water is not radioactive. In its pure form, it has a density about 11% greater than water, but otherwise, is physically and chemically similar. Nevertheless, the various differences in deuterium-containing water (especially affecting the biological properties) are larger than in any other commonly occurring isotope-substituted compound because deuterium is unique among heavy stable isotopes in being twice as heavy as the lightest isotope. This difference increases the strength of water’s hydrogen-oxygen bonds, and this in turn is enough to cause differences that are important to some biochemical reactions. The human body naturally contains deuterium equivalent to about five grams of heavy water, which is harmless. When a large fraction of water (> 50%) in higher organisms is replaced by heavy water, the result is cell dysfunction and death.[2]

    Heavy water was first produced in 1932, a few months after the discovery of deuterium.[3] With the discovery of nuclear fission in late 1938, and the need for a neutron moderator that captured few neutrons, heavy water became a component of early nuclear energy research. Since then, heavy water has been an essential component in some types of reactors, both those that generate power and those designed to produce isotopes for nuclear weapons. These heavy water reactors have the advantage of being able to run on natural uranium without the use of graphite moderators which can pose radiological[4] and dust explosion[5] hazards in the decommissioning phase. Most modern reactors use enriched uranium with normal “light water” (H2O) as the moderator.
