Mitochondrial Complex II, also known as succinate dehydrogenase (SDH), occupies a unique position at the intersection of the tricarboxylic acid (TCA) cycle and the mitochondrial electron transport ...

A study by the Center for Redox Processes in Biomedicine (Redoxoma) led by Marilene Demasi from the Butantan Institute (São Paulo, Brazil) presents a valuable new experimental model for investigating ...

At the dawn of complex life, evolution created a container for DNA, its most treasured item. A few billion years later, 20th-century microscopists looked at this container — the nucleus — up close and ...

Scientists have discovered that complex life began evolving much earlier than traditional models suggested. Using an expanded molecular clock approach, the team showed that crucial cellular features ...

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

In his laboratory at the University of Poitiers in France, Abderrazak El Albani contemplates the rock glittering in his hands. To the untrained eye, the specimen resembles a piece of golden tortellini ...
