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 surroundings instead of breathing on oxygen.
阅读全文动物植物终极自我牺牲：细菌激活异常防御以逃避病毒攻击
For billions of years, viruses and bacteria have been embroiled in an arms race. In response to constant attacks by viruses known as bacteriophages—more commonly called "phages"—bacteria evolve new ways to defend themselves. And, in turn, phages
