#1 Complex I enzyme revealed The solved structure of a bacterial complex I enzyme -- first in line in the energy-producing respiratory chain -- reveals important mechanics of this ubiquitous protein. Specifically, the structure shows how it hustles electrons and protons across membranes. R.G. Efremov et al.

#2 Unusual aging in E. coli A novel microfluidics technique allowed researchers to study single E. coli cells as they birthed many clones throughout many generations -- proving their growth rate wasn't hampered by age, contradicting previous hypotheses and other aging models.
