Researchers were able to identify changes in the accessibility (that is, the 'readability') of transposable elements. To do this, the researchers used an approach combining various sets of multiomics data, which characterize and quantify collections of biomolecules in cells or organisms. One was the transcriptome, which consists of all copies of RNA transcribed from DNA in the cell. The other was the epigenome, which is the collection of chemical changes to DNA that modify gene expression. An advantage of this multiomics approach is that they were able to identify families of transposable elements with changes in accessibility, which would have likely been missed by previous approaches.

The deadly hospital pathogen Acinetobacter baumannii can live for a year on a hospital wall without food and water. Then, when it infects a vulnerable patient, it resists antibiotics as well as the body's built-in infection-fighting response. The World Health Organization (WHO) recognizes it as one of the three top pathogens in critical need of new antibiotic therapies. Now, an international team, led by Macquarie University researchers Dr. Ram Maharjan and Associate Professor Amy Cain, have discovered how the superbug can survive harsh environments and then rebound, causing deadly infections. They have found a single protein that acts as a master regulator. When the protein is damaged, the bug loses its superpowers allowing it to be controlled, in a lab setting. The research is published this month in Nucleic Acids Research.
