‘Poisoned arrow’ defeats antibiotic-resistant bacteria

Staphylococcus aureus illustration (stock image).Credit: © nobeastsofierce / stock.adobe.com Poison is lethal all on its own — as are arrows — but their combination is greater than the sum of their parts. A weapon that simultaneously attacks from within and without can take down even the strongest opponents, from E. coli to MRSA (methicillin resistant Staphylococcus aureus).advertisement […]

How bacteria control their cell cycle

Researchers at the Biozentrum of the University have demonstrated how bacteria coordinate cell division with the replication of their genetic material. In an interdisciplinary study they explain why the current concept of the bacterial cell cycle has to be rewritten. The results were published in eLife.advertisement Each living cell grows and divides, thus generating new offspring. […]

Trial suggests babies in intensive care can be better protected from parental bacteria

For sick or prematurely born babies spending their first days of life in a hospital’s neonatal intensive care unit (NICU), the soothing voice and gentle touch of a loving parent can have a tremendous impact toward a positive outcome — that is, unless mom or dad’s visit leaves the infant with something extra: a dangerous […]

Ancient ‘chewing gum’ yields insights into people and bacteria of the past

Researchers from the University of Copenhagen have succeeded in extracting a complete human genome from a thousands-of-years old “chewing gum.” According to the researchers, it is a new untapped source of ancient DNA.advertisement During excavations on Lolland, archaeologists have found a 5,700-year-old type of “chewing gum” made from birch pitch. In a new study, researchers […]

Bacterial communities ‘hitchhiking’ on marine plastic trash

Millions of tons of plastic trash are fouling the world’s ocean, most of it tiny pieces of microplastic less than a quarter-inch in size. Even the smallest marine animals can ingest these microplastics, potentially threatening their survival.advertisement Marine microplastics aren’t floating solo, either — they quickly pick up a thin coating of bacteria and other […]

Laboratory-evolved bacteria switch to consuming carbon dioxide for growth

E. coli illustration (stock image).Credit: © fusebulb / Adobe Stock Over the course of several months, researchers in Israel created Escherichia coli strains that consume CO2 for energy instead of organic compounds. This achievement in synthetic biology highlights the incredible plasticity of bacterial metabolism and could provide the framework for future carbon-neutral bioproduction. The work appears November 27th in the […]

Dangerous bacteria communicate to avoid antibiotics

Bacteria illustration (stock image).Credit: © Christoph Burgstedt / Adobe Stock A bacterial infection is not just an unpleasant experience — it can also be a major health problem. Some bacteria develop resistance to otherwise effective treatment with antibiotics. Therefore, researchers are trying to develop new types of antibiotics that can fight the bacteria, and at the […]

The discovery of a third form of flagella-mediated motility shown by symbiotic bacteria

Many species of swimming bacteria have a rotary structure called a “flagellum,” consisting of more than twenty different kinds of proteins. By rotating their flagellar filaments and gaining propulsion, bacteria can swim freely in water. Flagella-mediated motility is essential for bacteria to move in search for better habitats and two forms have been known to […]
