Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

Plant cell cultures are an attractive alternative to cultivating whole plants for obtaining natural compounds, but many ...

Bacteria are enclosed by protective cell walls, made from a unique substance called peptidoglycan. This material is absent in other life forms, including humans, which is why many antibiotics target ...

Bacterial sensory systems represent a dynamic and rapidly evolving area at the intersection of molecular microbiology and biochemistry, where recent ...

Plants are a rich and renewable source of compounds used in medicines, food ingredients, and cosmetics. Since growing an ...

Genomic analysis shows SAR11 bacteria, adapted to low-nutrient oceans, lack key cell cycle controls. As conditions change, ...

University of Toronto researchers have expanded our understanding of bacterial immunity with the discovery of a new protein ...

Common gut bacteria use protein delivery systems to interact directly with human cells, reshaping how scientists view the ...

Spanish scientists have discovered a special protein emitted by a specific type of bacteria which could be helpful in the self-destruction of cancerous cells. According to new research published in ...

Antibiotic resistance is considered one of the most urgent health threats of our time. Common bacteria such as E. coli and Staphylococcus aureus are evolving defenses against the drugs doctors rely on ...

Scientists say they have shed new light on how bacteria protect themselves from certain phage invaders -- by seizing genetic material from weakened, dormant phages and using it to 'vaccinate' ...
