A new model for heart valve disease drug discovery

An article published in Experimental Biology and Medicine describes a new model for heart valve physiology. The study, led by Dr. Carla Lacerda, from the Department of Chemical Engineering at Texas Tech University reports ...

Scientists delineate pathway that helps us make antibodies

Our bodies are continuously concocting specific antibodies to thwart invaders like a virus or even pollen, and scientists have new information about how the essential production gets fired up and keeps up.

Survivor antibody clears path for new Ebola vaccine

An antibody taken from an Ebola survivor has been found to target all three human strains of the virus and could eventually lead to an all-purpose vaccine against the killer disease, scientists said Monday.

What impact does epigenetics have on our psychology?

In the battle of nature versus nurture, nurture has a new recruit: epigenetics—brought in from molecular biology to give scientific heft to the argument that genes are not destiny. The overwhelming evidence for genetic ...

Molecular biology

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.

Writing in Nature, William Astbury described molecular biology as:

"[...]not so much a technique as an approach, an approach from the viewpoint of the so-called basic sciences with the leading idea of searching below the large-scale manifestations of classical biology for the corresponding molecular plan. It is concerned particularly with the forms of biological molecules and[...]is predominantly three-dimensional and structural—which does not mean, however, that it is merely a refinement of morphology. It must at the same time inquire into genesis and function."
