Bacteria are different from you and me. Always the minimalists, they lack features that plant and animal cells usually can’t do without: a nucleus, special organelles, and an internal skeleton made of ...

Bacteria are also able to communicate with each other through chemical signals, a behavior known as quorum signaling (QS). These chemical signals spread through a biofilm that colonies of bacteria ...

A decade after microbiologists began to suspect that many groups of bacteria can communicate -- by releasing and detecting chemical pheromones to gauge their population density -- the molecular ...

July 25 (UPI) --Scientists have discovered unusual structures in rare bacteria that resemble the cellular components that power photosynthesis. The discovery, described this week in the journal Trends ...

The surface of pathogenic bacteria like E. coli contains hair-like structures called pili, which help bacteria bind to a host cell and stimulate infection. Researchers identified a new stage of pilus ...

AMES, Iowa – Two new discoveries from Edward Yu’s Iowa State University laboratory are adding to the scientific understanding of how bacteria resist antibiotics. Yu and his research group have just ...

Within the nucleus of each cell are the blueprints for life, DNA, and it has to be carefully organized into chromosomes not only for a good fit but also in order to properly regulate genes.

PHILADELPHIA - By combining two techniques, an international team of scientists led by researchers at The Wistar Institute has derived the "quasi-atomic" structure of a common bacteriophage, a type of ...

Limnology and Oceanography, Vol. 56, No. 1 (2011), pp. 37-48 (12 pages) Flow cytometric determinations of membrane integrity, nucleic acid content, and respiratory activity were combined with dilution ...

Researchers from the University of Maryland School of Medicine and their colleagues have identified the structure of the most lethal toxin produced by certain strains of Clostridium difficile bacteria ...
