Hydrogen cyanide, a toxic chemical, may have helped spark the chemistry that led to life. When frozen, it forms crystals with highly reactive surfaces that can drive unusual chemical reactions, even in extreme cold. These reactions could produce more reactive molecules that pave the way for life’s basic ingredients. TheContinue Reading
