What was the arsenic bacteria study and why was it retracted?
The 2010 study claimed bacteria could incorporate arsenic into DNA instead of phosphorus, challenging fundamental biology. However, in 2025, the paper was retracted due to methodological flaws like contamination and improper DNA purification. Critics argued the findings were flawed, and the retraction highlights the importance of scientific self-correction. Despite the retraction, some researchers and NASA still stand by the original data, fueling ongoing debate.

How do retractions impact scientific progress?
Retractions are a vital part of science, helping to correct errors and maintain integrity. While they can temporarily shake confidence, they ultimately strengthen scientific knowledge by removing false or flawed findings. Retractions also remind researchers to follow rigorous methods and verify results before publication.
