Researchers at the French "Montpellier" Institute for Cancer Research have discovered a new component that occurs in human blood, confirming that they were able to fully monitor it for the first time in the history of medicine, according to Sky News.

The component is known in the scientific community as "nematode" or "mitochondria" and usually remains inside the cell, but the scientific team has discovered that it circulates in the blood.

These "filaments" are part of the cell, and they play an important role in the body obtaining energy, and are known to be within the cell.

In addition to energy, "filamentous granules" help to communicate between cells, and are described by researchers as "the cell battery."

The study took seven years to complete, the researchers relied on the electron microscope, and then examined blood samples taken from 100 people.

Scientists are betting on this medical examination in order to understand the exact way in which cells function, and the discovery is likely to help develop immune system treatments and infections.
