How Did Life Arise? Fuel Cells May Have Answers
How life arose from the toxic and inhospitable environment of our planet billions of years ago remains a deep mystery. Researchers have simulated the conditions of an early Earth in test tubes, even fashioning some of life’s basic ingredients. But how those ingredients assembled into living cells, and how life was first able to generate energy, remain unknown.
A new study led by Laurie Barge of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., demonstrates a unique way to study the origins of life: fuel cells. (more…)
