Origin of life: An artificial comet holds the missing piece

Latest Science News -- ScienceDaily - Hace 2 horas

Researchers have for the first time shown that ribose, a sugar that is one of the building blocks of genetic material in living organisms, may have formed in cometary ices. They propose the first realistic scenario for the formation of this key compound, which had never been detected in meteorites or cometary ices until now. Their findings shed new light on the emergence of life on Earth.
