A new study reveals hydrogen gas’s role as an energy source at life’s dawn, underscoring its potential as a sustainable fuel. Through examining the natural processes at hydrothermal vents and the early cellular mechanisms for harnessing hydrogen, researchers have gained insights into the origins of life and the ancient utilization of hydrogen as an energy source. This research not only illuminates hydrogen’s historical significance but also its future role in sustainable energy.
How cells solve that problem was discovered only 15 years ago by Wolfgang Buckel together with his colleague Rolf Thauer in Marburg. They found that cells send the two electrons in hydrogen down different paths. One electron goes far downhill, so far downhill that it sets something like a pulley in motion that can pull the other electron energetically uphill. This process is called electron bifurcation.
Since the discovery of electron bifurcation, scientists have found that the process is both ancient and absolutely essential in microbes that live from H.

Uncovering the mystery of Dorset's Cerne GiantFor centuries, the Cerne Giant, a figure carved into a hillside in Dorset, has fascinated locals and visitors to the area. A new paper proposes that the Cerne Giant can in fact be dated to the early Middle Ages, and, as a result, its cultural context and significance more clearly understood.
