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.

Why do teeth form in a single row?

A system of opposing genetic forces determines why mammals develop a single row of teeth, while sharks sport several, according to a study published in the journal Science.

Two compounds show great promise for cerebral palsy

Two compounds developed by Northwestern University chemists have been shown to be effective in pre-clinical trials in protecting against cerebral palsy, a condition caused by neurodegeneration that affects body movement and muscle coordination.

Researchers block immune cell rush behind deadly sepsis

Researchers have found a way to block the ability of white blood cells to sprint toward the sites of infection when such speed worsens the damage done by sepsis, the often fatal, whole-body bacterial infection, according to a study published today in the journal Blood.

Scientists identify lab-made proteins that neutralize a broad range of influenza A viruses

Scientists have identified a small family of lab-made proteins that neutralize a broad range of influenza A viruses, including the H5N1 avian virus, the 1918 pandemic influenza virus and seasonal H1N1 flu viruses.

Scientists identify human monoclonal antibodies effective against bird flu

Researchers at the Dana-Farber Cancer Institute (Dana-Farber), Burnham Institute for Medical Research (Burnham) and the Centers for Disease Control and Prevention (CDC) have reported the identification of human monoclonal antibodies (mAb) that neutralize an unprecedented range of influenza A viruses, including avian influenza A (H5N1) virus, previous pandemic influenza viruses, and some seasonal influenza viruses.

Lynx2 gene linked to nervous behavior in mice

To measure anxiety in a mouse and suggest it's similar to anxiety in a person may seem like a stretch, but the metrics sound uncannily familiar.

Forgotten and lost -- when proteins 'shut down' our brain

Which modules of the tau protein, in neurons of Alzheimer disease patients, may act in a destructive manner were investigated by researchers from the Max Planck Institute for Biophysical Chemistry (Göttingen) and the Max Planck Unit for Structural Molecular Biology (Hamburg) with the help of Nuclear Magnetic Resonance Spectroscopy ( PLoS Biology , February 17, 2009).

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.

Groundbreaking study reveals how enzymes in the cell cooperate to make fat

These enzymes are integrated into a single molecular complex known as fatty acid synthase. This complex is regarded as a potential target for developing new anti-obesity and anti-cancer drugs.

Targeted immune cells shrink tumors in mice

Researchers have generated altered immune cells that are able to shrink, and in some cases eradicate, large tumors in mice.

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.

Discovery of important drug target for influenza

Influenza is and remains a disease to reckon with. Seasonal epidemics around the world kill several hundred thousand people every year.

5 Feb 2009

FOXO3A gene variation may be key to longer life

A variation in the gene FOXO3A has a positive effect on the life expectancy of humans, and is found much more often in people living to 100 and beyond - moreover, this appears to be true worldwide.

New chemical keeps stem cells young

Scientists at the Universities of Bath and Leeds have discovered a chemical that stops stem cells from turning into other cell types, allowing researchers to use these cells to develop new medical treatments more easily.

Researchers disrupt biochemical system involved in cancer, degenerative disease

Screening a chemical library of 200,000 compounds, researchers at UT Southwestern Medical Center have identified two new classes that can be used to study and possibly manipulate a cellular pathway involved in many types of cancer and degenerative diseases.
