The newly found chemical pathway, reported by researchers from Science Tokyo, shows that HCN could instead have been continuously supplied from abundant amino acids.<\/div>\n<p><a target=\"_blank\" href=\"https:\/\/phys.org\/news\/2026-04-overlooked-mineral-quietly-powered-crucial.html\" target=\"_blank\">Go to Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Manganese dioxide can convert amino acids into hydrogen cyanide (HCN) without requiring methane, a finding that solves a long-standing puzzle about the origin of this key prebiotic molecule on early Earth.
