After more than a decade of scrutiny, the landmark study that claimed bacteria could incorporate arsenic into their DNA, challenging foundational biological principles, has been officially retracted by the journal Science. Published in 2010, the research sparked excitement and skepticism in equal measure, as it suggested an alternative biochemistry for life beyond the canonical six elements. However, subsequent studies failed to replicate the findings, raising concerns about experimental design and data interpretation that ultimately led to this decision.

The controversy surrounding the study highlighted several critical issues in scientific publishing and peer review, including:

  • Replicability challenges as independent labs could not reproduce key…
