few days ago Sciencie magazine published an article which alleged the existence of bacteria that had arsenic instead of phosphorus in their DNA.
carefully read the scientific community the research process and see some anomalies, such
notes that are bacteria support high concentrations of arsenic, its size increases, but do not demonstrate that arsenic is in the DNA, is in the garbage bins ("vacuoles" that have some bacteria) to not bother, of course they have a place and so increases volume of the bacteria. Being a bad idea
seems that NASA wants to make sure the capital to keep looking for life on other planets.
