Biofilm streamers harden under flow, making bacterial infections harder to treat
Whether in the human body or on surfaces, bacteria protect themselves from outside attackers using biofilms. Physicist Eleonora Secchi is researching how these slime-like protective films are formed, with the aim of making it easier to remove pathogenic bacteria.
Nanoplastics in water help bacteria form stronger, disinfectant-resistant biofilms
Human health risks from direct consumption of toxic nanoplastics are already scary, but researchers have confirmed that nanoplastics in water give rise to an additional threat: They strengthen bacteria.
Plastisphere: a new term that involves the interaction between organisms, plastics, and the environment. arriers for other chemical contaminants, including ultraviolet (UV) filters from sunscreen.

Microplastics, the microscopic and nano-sized plastic particles that are invading our bodies, lend a hand to bacteria attempting to evade our most powerful antibiotics.

Microplastics, the microscopic and nano-sized plastic particles that are invading our bodies, lend a hand to bacteria attempting to evade our most powerful antibiotics. Boston University bioengineers studied this phenomenon using E. coli, the bacteria that often cause serious and sometimes deadly food poisoning,
The investigators show that, when these bacteria attach to microplastics, they are able to more readily form so-called biofilms. These multi-layered film coatings serve as refuge for the bacteria and prevent even powerful antibiotics from killing them.
The BU group is expanding its work from the laboratory to the clinic. By understanding how these ubiquitous microplastics are empowering bacteria in their resistance tour antibiotics, they hope to reverse the trend toward a greater number of antibiotic-resistant bugs. Meanwhile, your best defense is keeping microplastics out of your body by drinking water, cooking, and storing food in glass and metal rather than plastic containers.

Innovative 'Four Ponds and Two Dams' wetland system enhances aquaculture wastewater treatment
Aquaculture wastewater, rich in organic matter, nitrogen and phosphorus, poses a significant environmental threat when discharged untreated, leading to eutrophication and water quality degradation.
Discovery of stromatolite-like biofilms in thermal waters sheds light on ancient ecosystems
Hungarian researchers have discovered unique bacterial communities in thermal waters that may help unravel the development of stromatolites, one of Earth's oldest rock formations. These findings not only contribute to understanding Earth's geological past but also provide valuable insights into biological and geological processes occurring in extreme environments today.
