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.

Natural antibiotic to treat tuberculosis

A natural product secreted by a soil bacterium shows promise as a new drug to treat tuberculosis report scientists in a new study published in EMBO Molecular Medicine. A team of scientists working in Switzerland has shown how pyridomycin, a natural antibiotic produced by the bacterium Dactylosporangium fulvum, works.

Drug-resistant tuberculosis: an interview with Sven Hoffner

In contrast to drug-susceptible tuberculosis, which can be cured with available drug therapies, drug-resistant, and especially multi-drug resistant, tuberculosis is much more difficult to cure and it takes a much longer time for patients to become non-infectious.

Researchers hold new implications for pathogenesis of myotonic dystrophy

An important breakthrough could help in the fight against myotonic dystrophy. The discovery, recently published in the prestigious scientific journal Cell, results from an international collaboration between researchers at the IRCM, the Massachusetts Institute of Technology (MIT), the University of Southern California and Illumina.

Brigham Young University scientists discover cellular cause of birth defects

The cellular cause of birth defects like cleft palates, missing teeth and problems with fingers and toes has been a tricky puzzle for scientists. Now Professor Emily Bates and her biochemistry students at Brigham Young University have placed an important piece of the developmental puzzle. They studied an ion channel that regulates the electrical charge of a cell. In a new study published by the journal Development, they show that blocking this channel disrupts the work of a protein that is supposed to carry marching orders to the nucleus.

New research offers ways in which investigators can reduce amount of Cd in foods

A number of environmental toxins pose considerable health threats to humans, and the heavy metal cadmium (Cd) ranks high on the list. Most of us are exposed to it through plant-derived foods such as grains and vegetables. Now, new research offers ways in which investigators can reduce the amount of Cd found in the food we eat, according to a review published online September 12th in the Cell Press journal Trends in Plant Science.

Scripps scientists discover new antibody-discovery technique

Scientists at The Scripps Research Institute have found a new technique that should greatly speed the discovery of medically and scientifically useful antibodies, immune system proteins that detect and destroy invaders such as bacteria and viruses. New methods to discover antibodies are important because antibodies make up the fastest growing sector of human therapeutics; it is estimated that by 2014 the top-three selling drugs worldwide will be antibodies.

Enzymatic sculpting process used to isolate and concentrate cells from whole blood

In living systems, complex nano- and microscale structures perform a host of physical and biological functions. While two-dimensional patterns can be recreated fairly well with techniques like microlithography, three-dimensional structures represent a big challenge.

CSHL publishes genome-wide analysis of transcripts produced within human cells

Most people understand genes to be specific segments of DNA that determine traits or diseases that are inherited. Textbooks suggest that genes are copied into RNA molecules, which are then used as templates for making protein - the highly diverse set of molecules that act as building blocks and engines of our cells. The truth, it now appears, is not so simple.
