A 2010 study in Science magazine claiming the discovery of arsenic-based life was retracted Thursday. Researchers originally suggested bacteria in a California lake used arsenic to grow, expanding the possibilities of extraterrestrial life. However, other scientists couldn't replicate the findings, citing potential contamination. While the journal retracted the paper due to unsupported conclusions, not misconduct, the original researchers disagree with the decision, highlighting ongoing scientific debate.
