Bacteria must be 'stressed out' to divide
Bacterial cell division is controlled by both enzymatic activity and mechanical forces, which work together to control its timing and location.

The evolution of dietary and hygienic habits in Western countries is associated with a decrease in the bacteria that help in digestion. These very bacteria were also found in the Iceman, who lived 5300 years ago, and are still present in non-Westernized populations in various parts of the world. The depletion of the microbiome may be associated with the increased prevalence, in Western countries, of complex conditions like allergies, autoimmune and gastrointestinal diseases, obesity.
Researchers have discovered an enzyme they believe could be key to preventing Group A Streptococcus infections that cause more than 500,000 deaths worldwide each year. The enzyme works through a novel mechanism of action that can also be found in other streptococcal species, increasing the impact and relevance of this finding.
Read moreScientists have isolated a natural chemical that acts as a potent kryptonite against parasitic worms that burrow through human skin and cause devastating health problems. Researchers now describe the successful characterization of this chemical, which could help in finding new ways to fight the neglected tropical disease schistosomiasis.
Read moreScientists have uncovered a novel antibiotic-free approach that could help prevent and treat one of the most widespread bacterial pathogens, using nanocapsules made of natural ingredients.
Read moreNew research shows that ants inhibit at least 14 different plant diseases. The small insects secrete antibiotics from glands in the body. On their legs and body, they also host colonies of bacteria that secrete antibiotics. It is probably these substances that inhibit a number of different diseases and researchers now hope to find biological pesticides that may conquer resistant plant diseases.
Read moreResearchers have developed an improved assembly of the genome for the date palm using long-read sequencing technology. This improvement over the current versions of the genome will help advance further research, and also inform the propagation practices of this essential MENA region food source.
Read moreMicroscopic droplets on the surface of leaves give refuge to bacteria that otherwise may not survive during the dry daytime, according to a new study.
Read moreDeep-sea mussels, which rely on symbiotic bacteria for food, harbor a surprisingly high diversity of these bacterial 'cooks': Up to 16 different bacterial strains live in the mussel's gills, each with its own abilities and strengths. Thanks to this diversity, the mussel is prepared for all eventualities, researchers report.
