NASA made an announcement, following their findings in a recent study that suggests that we may have been overlooking life on earth and in space. The researchers found a bacterium that can grow with arsenic in substitution of phosphorus, which was previously thought to be essential for all life on earth.
The study, funded by NASA, was published online in the journal Science and announced in a press conference streamed live on NASA’s website today.
The scientists successfully grew the bacterium adding arsenic to its growth medium instead of phosphorus.
This research suggests that there may be life on earth and in space that uses arsenic and thus does not need phosphorus at all.
Furthermore, given these findings, the researchers think elements like carbon, hydrogen, nitrogen, oxygen, and sulfur might possibly be replaced by their similar elements in some existing, but as of yet undiscovered, life.
This indicates that in our search for life in space, we may have overlooked planets that don’t contain these elements but that actually have life, with these forms of life using elements different from what we have previously thought of as life-creating materials.
In his 1990 book Paradigms Lost, John L. Casti explores different theories of the origin of life, considering different arguments for and against each, in the end arguing that the most plausible model is that life began with silicon crystal formations, instead of carbon.
Just letting everyone informed, this increases the chance of different extraterrestrial life forms, maybe life isn't a standard of elements combined with local weather standards, but something that starts and gets adapted to the area, the conclusion is: Not only planets similar to the earth may lodge a living biological being

Nick - Trees are already a form of life o.o and actually food exist for a reason, what means food = Life too, i think you got this information from a bad source
lol just kidding but this is very interesting because nasa has foung a planet they named glesa (i think i spelled that wrong) and it has almost all the stats earth has and is able to have life so if you think about it many other planets can be the same and have life. good job gleeok
