Last week, I posted on a widely-reported NASA contention that agency scientists had caused microbes to accept a diet of arsenic, rather than phosphorus, thereby expanding the possible bases of life. (The contention was published in the journal Science and reported widely.) Over the weekend, scientists in America and abroad began to challenge the findings,…

Arsenic-Based Microbes Challenge Chemistry of Life – WSJ.com

Quite the innovation — Researchers on Thursday said they had created microbes that “very likely” use arsenic in their DNA in place of phosphorus, in what may be the first exception to the formula long thought to govern the basic chemistry of life. Force-grown in the lab, the bacteria use the notorious poison to replace…
