A study on stem cells is presented by understanding the environment in which they are found, the support cells and blood vessels as well as the protein scaffolds and other molecules. Researchers found that stem cells in reproductive tissue are surrounded by a pocket of support cells that hold them in place and align them to divide properly, so…

Explains the history and structure of RNA. Discusses small RNAs and the role of assumptions in science. (Contains 19 references.) (YDS)

Discusses humans' interest to other organisms and how this attraction draws humans to such stories and indirectly to biology. Analyzes the gaps between molecular biology and ecology in education. (Contains 13 references.) (YDS)

Explores new research about bacteria. Discusses bacterial genomes, archaea, unusual environments, evolution, pathogens, bacterial movement, biofilms, bacteria in the body, and a bacterial obsession. Contains 29 references. (JRH)

Some innovations in the images of cells and molecules that keep changing for new techniques and as a result of using new approaches to old methods are explored and new ways of illustrating cell and molecular structures are discussed. The three elements that play an important role in any biological image are aesthetic factors such as picture style…

Argues that biologists' understanding of the cell has become richer over the past 30 years. Describes how genetic engineering and sophisticated computer technology have provided an increased knowledge of genes, gene products, components of cells, and the structure and function of proteins. (CCM)
