Matt WillemsenThe Unsolved Enigma of the Origin of Life: A New Strategy
The origin of life remains a scientific enigma, with research divided between “bottom-up” methods, which simulate early Earth environments, and “top-down” methods that use evolutionary biology to trace back life forms. A recent interdisciplinary article suggests bridging these methodologies by studying electron transport chains, a universal metabolic system, offering insights into life’s earliest metabolic strategies and origin.

The Unsolved Enigma of the Origin of Life: A New Strategy
Despite years of advancements, the origin of life continues to be one of science's most enduring mysteries. “The most basic features of biology, that organisms are made of cells, that they pass genetic information through DNA, that they use protein enzymes to run their metabolism, all emerged thr

Light-driven CO2 assimilation by photosystem II and its relation to photosynthesis
Photosynthesis is the greatest natural process on Earth, converting sunlight into chemical energy on a massive scale and maintaining life. There are basically two successive stages of oxygenic photosynthesis, of which the light-dependent reactions in photosystem II (PSII), and in photosystem I (PSI), enable the oxidation of H2O into molecular oxygen, and production of reducing power (NADPH and ATP), while CO2 assimilation is generally known to take place long after oxygen evolution and NADP+ reduction, via light-independent reactions in the stroma.
