NewsNew study uncovers the complex history of the plague after the Black Death
A new study sheds fresh light on the long and complex history of the plague by analysing the DNA of the bacterium. Researchers reconstructed 26 genomes of Yersinia pestis from archaeological sites in Estonia, Russia, England, the Netherlands, and Switzerland.

NewsNew discovery could hold key to making microbes more resistant towards industrial processes
In the bacterium Pseudomonas putida, the membrane protein CrcB pumps harmful fluoride ions out of the cells. Researchers investigated how P. putida adapts to a fluoride-containing environment, when it is deprived of the ability to produce the CrcB protein.

NewsAntibacterial coatings with short-term effect may fail over longer periods of time
Researchers have shown that antibacterial coatings which initially appear highly effective at destroying bacteria may lose their performance over time. Therefore, long-term testing is essential for developing the best antibacterial materials.

NewsMedications leave lasting mark on the gut microbiome, even years after use
Analysing stool samples and prescription records from over 2,500 Estonian Biobank participants, researchers found that the majority of drugs studied were linked to microbiome changes, with a substantial number of them also showing long-term effects detectable years after patients stopped taking them.
