NewsCargo system inhibits E.coli biofilms with a fraction of the antibiotic dose
Scientists have designed a bacteria-targeted cargo system that is capable of inhibiting a quinolone resistant Escherichia coli biofilm using much lower levels of antibiotic. The researchers, from Koç University School of Medicine in collaboration with College of Science, Department of Chemistry, encapsulated the antibiotic ciprofloxacin into superparamagnetic iron oxide nanoparticles ...

NewsGlitter impairs growth of cyanobacteria, study shows
Use of glitter in makeup, party costumes and decorations should be reconsidered, say researchers who investigated the effects of five concentrations of glitter on two strains of cyanobacteria.

NewsWhale shark health relies on habitat, diet – and the right mix of microbes
Scientists from around the world have collaborated to sample microbes on the skin surface of the world’s largest fish – the whale shark (Rhincodon typus) – at five of the most famous diving sites around the world.

NewsNew insight into how bacteria surf cargo through the cell before division
Researchers have found some bacteria ship cellular cargo by ‘surfing’ along proteins called ParA/MinD ATPases.

NewsTick- and mosquito-borne diseases prevalent in shelter dogs
Ticks and mosquitoes are expanding their geographic range due to warming temperatures, frequently bringing disease, and a new study suggests shelter dogs in the eastern U.S. may be bearing the brunt of that burden.

News Mapping methane emissions from rivers around globe reveals surprising sources
Researchers have found that methane emissions in tropical aquatic habitats are comparable to those in the much colder streams and rivers of boreal forests and Arctic tundra habitats.

NewsTests of new antifungal therapy for fungal meningitis are successful
Researchers have successfully tested a new oral formulation of the antifungal medication amphotericin among people who had HIV and cryptococcal meningitis - a common fungal infection around the brain.

NewsCattle may face much higher TB risk from indirect interactions with wildlife
Cattle face a hypothetically high risk of getting tuberculosis from wildlife - such as deer, foxes, and wild boar - through indirect interactions, with a much lower risk from direct interactions, a new study suggests.

NewsHigh-fat diets alter gut bacteria, boosting colorectal cancer risk in mice
Scientists have pinpointed specific microbes and bile acids that become more prevalent in the guts of mice fed high-fat diets.

NewsEnergy depleting mechanism immunizes bacteria against phages
Researchers have described a new family of proteins that deplete cells of their energy, thereby protecting the cells from invaders. The previously unknown immune mechanism is used by many living creatures, from bacteria to bees.

NewsResearch team develop nano-sized force sensor and improve high-precision microscopy
In many cases, cells are very active in their movement and serve as power generators. The ability of cells to produce physical forces is one of the basic functions of the body. When running, for example, the forces generated in the cells cause the muscles to contract and the breath ...

NewsResearchers reveal how Salmonella relatives grow together in the gut
Scientists investigating the dynamics of bacterial coexistence in the gut discovered how a secondary group of bacteria can thrive when closely related resident bacteria are present.

NewsViral relicts in the genome could fuel neurodegeneration
Genetic remnants of viruses that are naturally present in the human genome could affect the development of neurodegenerative diseases by contributing to the spread of aberrant protein aggregates in the brain.

NewsN-protein research reveals role of human body temperature in Covid proliferation
Researchers shed light on a pivotal part in the RNA-binding mechanism of the nucleocapsid protein (N) – SARS-CoV-2 probably uses human body temperature for its proliferation strategy.
