medi-peel-bor-tox-peptide-ampoule-ingredients Scientists have identified a simple molecule, nicknamed "Nickelback," that may have played a pivotal role in kick-starting life on Earth. This specific peptide, composed of 13 amino acids and featuring two crucial nickel atoms, is a leading candidate for an ancestral biomolecule that facilitated early chemical reactions essential for life's emergence. The discovery, spearheaded by researchers at Rutgers University, suggests that such nickel-binding peptides could have been abundant on prebiotic Earth, where nickel was readily available.
