Scientists at University College London found that rigor Mortis (lat. rigor mortis) in worms Caenorhabditis elegans starts when they are still alive. The first phase of this phenomenon is reminiscent of the aging process in humans, and researchers believe that there must be a way to stop dying. This publication reports Science Alert, reports Rus.Media.

Death in mammals occurs due to cessation of blood flow, however, is not as nematodes of the respiratory and circulatory system. Gas exchange with the environment, these invertebrates made the whole surface of the body. Therefore, the worms rigor Mortis occurs before death, not after, like most other animals.

Experts have shown that at the time of death of cells allocated anthranilate acid, causing blue fluorescence. The glow spreads in a wave, which suggests that rigor mortis does not occur simultaneously throughout the body.

Rigor Mortis is due to the fact that the cells cannot produce ATP — a molecule of ATP that are the energy source for most vital chemical reactions. The result is allocated to calcium ions, which cause a permanent muscle contraction.

Scientists have shown that a significant reduction of ATP levels in the cells of the worms takes place right before death, but the exact cause of this phenomenon is still unknown. At the same time, the researchers noted the similarity of the relatively small depletion of adenosine triphosphate, which indicates the imminent death, with the fall of ATP levels in the body old people. Biologists believe that it is possible to prevent the dying of terminally ill patients if to find a way to raise the number energotejash molecules.
