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.

Johns Hopkins researchers uncover mechanism in chikungunya virus that controls disease severity

Researchers led by the Johns Hopkins Bloomberg School of Public Health have identified a mechanism by which the chikungunya virus infects healthy cells and controls how severe the disease it causes will be, a mechanism they believe can be found in a number of other related viruses for which there are no treatments or licensed vaccines.

Researchers discover earliest-acting protein in C-elegans that plays key role in cell division

Researchers from three U.S. universities have identified, using roundworms, the earliest-acting protein known to duplicate the centriole, a tiny cylinder-shaped structure that is a key component of the machinery that organizes cell division in animals.

Oral devices improve sleep in OSA patients but may not reduce key heart disease risk factors

In patients with severe obstructive sleep apnea (OSA), oral appliances that treat the condition by moving the lower jaw forward appear to improve sleep but not reduce key risk factors for developing heart and other cardiovascular disease, according to new research published online, ahead of print in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
