Calcium CH ligand with the bulkier C(CH) ligand on the other hand increases the compound's solubility, volatility, and kinetic stability. Natural calcium is a mixture of five stable isotopes (Ca, Ca, Ca, Ca, and Ca) and one isotope with a half-life so long that it can be considered stable for all practical purposes (Ca, with a half-life of about 4.3 × 10 years). Calcium is the first (lightest) element to have six naturally occurring isotopes. By far the most common isotope of calcium in nature is Ca, which makes up 96.941% of all natural calcium. It is produced in the silicon-burning
Society for Scientific Exploration X-Files or in the National Enquirer shows up first here. But what also shows up is a surprising attitude of skepticism." The society's magazine, the "Journal of Scientific Exploration", was established to provide a scientific forum for ufology, parapsychology and cryptozoology, having published research articles, essays, book reviews and letters on those and many other topics that are largely ignored in mainstream journals. The journal is currently edited by parapsychologist and philosopher Stephen E. Braude. The Spirituality and Psychiatry Special Interest Group of the Royal College of Psychiatrists says that the journal has reports about anomalies in science, particularly in
