Nanobes are tiny filamental structures found in some rocks and sediments. Some hypothesize that they are the smallest form of life, ten times smaller than the smallest known bacteria. The smallest are just 20 nanometers long. Some researchers believe them to be merely crystal growths, but a recent find of DNA in nanobe samples may prove otherwise. They are similar to the life-like structures found in the famous 1996 Mars rock from the Antarctic. Recently there has been some interest amongst bio-tech companies in commercial application of nanobes in utilization of plastics. Some researchers believe nanobe-like organisms might be implicated in a number of diseases.
