The scientists worked with bacteria that were deficient in the production of a certain amino acid and therefore depended on a partner to provide the missing nutrient. Bacterial strains that complemented each other’s need by providing the required amino acid showed a fitness increase of about 20% relative to a non-deficient strain without partner. This result helps to explain why cooperation is such a widespread model of success in nature.

Adding foods rich in specific amino and fatty acids to the diets of youth with Type 1 diabetes kept them producing some of their own insulin for up to two years after diagnosis, said researchers at the Gillings School of Global Public Health at the University of North Carolina at Chapel Hill."

Enabling bioengineers to design new molecular machines for nanotechnology applications is one of the possible outcomes of a study by University of Montreal researchers that was published in Nature Structural and Molecular Biology today. The scientists have developed a new approach to visualize how proteins assemble, which may also significantly aid our understanding of diseases such as Alzheimer's and Parkinson's, which are caused by errors in assembly.

An international team of researchers has reported a new understanding of a little-known process that happens in virtually every cell of our bodies. Protein folding is the process by which not-yet folded chains of amino acids assume their specific shapes, hence taking on their specific functions. These functions vary widely: In the human body, proteins fold to become muscles, hormones, enzymes, and various other components.
