Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Novel gene silencing platform

A team of researchers led by Rutgers' Samuel Gunderson has developed a novel gene silencing platform with very significant improvements over existing RNAi approaches.

How the sensory organs of bacteria function

Bacteria can occur almost anywhere on earth and exist under the most varying conditions. If these tiny, microscopic organisms are to survive in these environments, they need to be able to rapidly detect changes in their surroundings and react to them.

E. coli persists against antibiotics through HipA-induced dormancy

Bacteria hunker down and survive antibiotic attack when a protein flips a chemical switch that throws them into a dormant state until treatment abates, researchers at The University of Texas M. D. Anderson Cancer Center report in the Jan.16 edition of Science.
