Imaging technique reveals that bacterial biofilms are associated with colon cancer
Researchers from Johns Hopkins have found that dense mats of interacting bacteria, called biofilms, were present in the majority of cancers and polyps, particularly those on the right side of the colon. The ...
The new T. rex: A leech with an affinity for noses
A new leech species with ferociously large teeth -- recently discovered in noses of children that swam in Peruvian rivers -- is providing insight into the evolutionary relationships among all the leeches that ...
Carnivorous plant traps worms with sticky leaves
Plants eat the darndest things. Scientists have discovered a small flowering plant living in the sandy soils of Brazil that traps nematodes, or roundworms, with sticky underground leaves -- and gobbles them ...
Copper + love chemical = big sulfur stink

Scientists discover how a bacterial pathogen breaks down barriers to enter and infect cells
Scientists from the Schepens Eye Research Institute, a subsidiary of Mass. Eye and Ear and affiliate of Harvard Medical School, have found for the first time that a bacterial pathogen can literally mow down protective molecules, ...
Fighting bacteria with mucus
Slimy layers of bacterial growth, known as biofilms, pose a significant hazard in industrial and medical settings. Once established, biofilms are very difficult to remove, and a great deal of research has gone into figuring ...
