Single celled organisms in the environment are protecting pathogenic bacteria and priming them for human infection, an international team of researchers has discovered.

New DNA amplification capsule holds promise for fighting diseases

DNA amplification—a molecular "photocopying" technique where genetic material is replicated—has many applications in scientific research, forensic science, and medical laboratories. It is useful for detecting and identifying ...

Fractal patterns in growing bacterial colonies

As many people will remember from school science classes, bacteria growing on solid surfaces form colonies that can be easily visible to the naked eye. Each of these is a complex biological system in its own right; colonies ...

Hidden danger from pet dogs in Africa

Dogs in tropical Africa run the risk of contracting canine trypanosomosis if they are bitten by bloodsucking tsetse flies carrying trypanosomes—microscopic, single-celled organisms found in the bloodstream. In dogs, this ...
