[R]esearchers at the University of California San Diego who combine experiments and mathematical modeling have discovered an unexpected mechanism that allows bacteria to survive antibiotics.

As described in the March 7 early online release of the journal Cell, Dong-yeon Lee, Maja Bialecka-Fornal and Gürol Süel of UC San Diego's Division of Biological Sciences, along with Leticia Galera-Laporta of the Universitat Pompeu Fabra (Spain), and colleagues discovered that bacteria defend themselves against antibiotics by controlling the uptake of alkaline metal ions. When under attack by antibiotics, bacteria were found to modulate magnesium ion uptake in order to stabilize their ribosomes -- the fundamental molecular machines of life that translate genes into proteins -- as a survival technique.

[...] The new findings lay the scientific groundwork for new ways to counteract antibiotic resistance.

    DNA is used to store knowledge, if you want to think of it that way.
