This time around, it seems NASA scientists have found a type of bacterium whose DNA differs from all other life on the planet<\/strong>.<\/p>\n

All life on Earth is made of six components: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. The DNA of every living organism\u2014plants, animals, microbes\u2014is made up of these six elements.<\/p>\n

Every organism, that is, except for this newly-discovered bacterium.<\/p>\n

Much like the Horta from Star Trek<\/a> was silicon-based instead of carbon-based, this newly discovered bacteria replaces the phosphorus normally found as part of the DNA backbone with an element in the same column of the Periodic Table: arsenic<\/a>.<\/p>\n

Phosphorus is an integral part of all living organisms, down to the cellular level. It is the \u201cP\u201d in ATP<\/a>, the coenzyme used for intracellular energy transfer – used for important things like metabolism.<\/p>\n

However, NASA scientists, working with microbes from poisonous Mono Lake, California<\/a>, were able to cultivate these bacteria in an environment with very little phosphorus but high in chemically-similar arsenic. After removing the phosphorus completely, the bacteria still multiplied. Examination showed that the bacteria were using the arsenic in place of the phosphorus<\/strong>.<\/p>\n

Effectively, the bacteria was partially composed of arsenic, something that was previously thought to be impossible.<\/p>\n

This affects many aspects of science, from organic chemistry to the search for life on other planets. By expanding the \u201crequirements for life\u201d and not just restricting it to Earth-like environments<\/a>, it widens the opportunity to possibly finding life on other planets.<\/p>\n
