New research suggests that certain bacteria began using oxygen nearly one billion years earlier than previously thought. The findings could profoundly reshape our understanding of how life evolved on ...

A team led by Rice University bioscientist Caroline Ajo-Franklin has discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their ...

Moh El-Naggar, a biophysicist at the University of Southern California (USC), has been fascinated by these organisms for nearly two decades. After years of studying the dynamics of electron transfer ...

Researchers including Caroline Ajo-Franklin and Biki Bapi Kundu have discovered how certain bacteria breathe by generating electricity. By identifying how these bacteria expel electrons externally, ...

The organism, an early-evolving bacterium named Hydrogenobacter, thrives in the hydrothermal spring environments of Yellowstone National Park, which are rich in sulfur but have very low dissolved ...

Scientists have decoded the metabolic strategies of certain sulfur bacteria. A new study reports that the bacteria are found worldwide and have a complex metabolism with modular features. The ...

“Our research not only solves a long-standing scientific mystery, but it also points to a new and potentially widespread survival strategy in nature,” said Ajo-Franklin, professor of biosciences, ...
