• Researchers uncover a mechanism of how bacteria with the same genotype can show a different phenotype

  20-04-2017 20:00
  
  Bacterial populations pose an intriguing puzzle: in so-called isogenic populations, all bacteria have the same genes, but they still behave differently, for example grow at different speeds. Researchers at the Institute of Science and Technology Austria (IST Austria) now solved a part of this puzzle by studying how the bacterium Escherichia coli divides up a protein complex that detoxifies cells by pumping multiple drugs such as antibiotics out of the cell.

  Materials science researchers have developed a model that can account for irregularities in how atoms arrange themselves at the so-called "grain boundaries" - the interface where two materials meet. By describing the packing of atoms at these interfaces, the tool can be used to help researchers determine how grain boundaries affect the properties of metal alloys and other materials.
