Researchers at Rensselaer Polytechnic Institute have discovered new details about how bacteria generate energy to live. In two recently published papers, the scientists add key specifics to the molecular mechanism behind the pathogen that causes cholera. The work could provide a better understanding of this pathogen, while also offering insight into how cells transform energy from the environment into the forms required to sustain life.

There will soon be no more bitter pills to swallow, thanks to new research by University of Leeds scientists (UK): a spoonful of sugar will be all we need for our bodies to make their own medicine.

Answering one of the oldest questions in human physiology, researchers at Dana-Farber Cancer Institute have discovered why the body's immune system - perpetually on guard against foreign microbes like bacteria - doesn't attack tissues in the small intestine that harbor millions of bacteria cells.

Cincinnati burn researchers have created genetically modified skin cells that, when added to cultured skin substitutes, may help fight off potentially lethal infections in patients with severe burns.

In an advance in the emerging field of bacterial imaging, scientists are reporting development of a method for identifying specific sites of localized bacterial infections in living animals.
