A team of biophysicists affiliated with several institutions in China has uncovered via experimentation the means by which early life might have been able to survive cosmic radiation. In their study, reported in the journal ...
Who needs science fiction when you have the mitochondria? Billions of years ago, early plant and animal cells were infected by protobacteria which sought refuge from the outside world. Over time, these bacteria formed a symbiosis ...
Iron storage "spheres" inside the bacterium C. diff—the leading cause of hospital-acquired infections—could offer new targets for antibacterial drugs to combat the pathogen.
