NASA discovers unique new life form

What's the problem? Huge quantities with arsenic and huge quantities with UV-rays will kill you. Small doses doesn't.


My point is that we cannot use the bacteria to clean up a lake: I said that if the bacteria could choose between phosphorus and arsenic, it would pick phosphorus.

with the technology that we have today (or possibly in the future), it might be possible to genetically alter this bacterium to make it consume pollutants in water sources.
