First detailed microscopy evidence of bacteria at the lower size limit of life
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based description of the microbes until now. The cells have an average volume of 0.009 cubic microns (one micron is one millionth of a meter). About 150 of these bacteria could fit inside an Escherichia coli cell and more than 150,000 cells could fit onto the tip of a human hair.<img src="//feeds.feedburner.com/~r/sciencedaily/~4/n1P2lG5rWEM" height="1" width="1" alt=""/>
