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.

Exercise fails to improve glucose metabolism in autophagy-deficient mice

The health benefits of exercise on blood sugar metabolism may come from the body's ability to devour itself, UT Southwestern Medical Center researchers report in the journal Nature.

Minuscule amounts of ethanol can double C. elegans' life span

Minuscule amounts of ethanol, the type of alcohol found in alcoholic beverages, can more than double the life span of a tiny worm known as Caenorhabditis elegans, which is used frequently as a model in aging studies, UCLA biochemists report. The scientists said they find their discovery difficult to explain.

Combination of gefitinib and miRNA-inhibitor might effectively treat NSCLC

New research published in Nature Medicine indicates that targeted drugs such as gefitinib might more effectively treat non-small cell lung cancer if they could be combined with agents that block certain microRNAs.

Inherited mutation links exploding chromosomes to cancer

An inherited mutation in a gene known as the guardian of the genome is likely the link between exploding chromosomes and some particularly aggressive types of cancer, scientists at the European Molecular Biology Laboratory (EMBL), the German Cancer Research Centre (DKFZ) and the University Hospital, all in Heidelberg, Germany, have discovered.

Elsevier to publish The Ocular Surface that focuses on external eye and vision

Elsevier, a world-leading provider of scientific, technical and medical information products and services, is pleased to announce newly acquiring The Ocular Surface, a peer-reviewed journal focusing on the external eye and vision. As per January 2012 Elsevier will continue the publication of the quarterly journal.

Novel technique accurately maps gene-regulation proteins

A novel technique has been developed and demonstrated at Penn State University to map the proteins that read and regulate chromosomes -- the string-like structures inside cells that carry genes.

LabCorp announces nationwide availability of Risk of Ovarian Malignancy Algorithm

Laboratory Corporation of America Holdings announced today the nationwide availability of a new FDA cleared risk stratification tool (ROMA, Risk of Ovarian Malignancy Algorithm) that combines the results for Fujirebio HE4, Abbott's ARCHITECT CA 125 II, and menopausal status into a numerical score that, along with clinical and radiological evaluation, can aid in evaluating whether a woman over the age of 18 who presents with an ovarian mass and for whom surgery is planned is at high or low likelihood of finding malignancy on surgery.

Georgia Tech findings advance glaucoma research

Glaucoma is the second leading cause of blindness. Nearly 4 million Americans have the disorder, which affects 70 million worldwide. There is no cure and no early symptoms. Once vision is lost, it's permanent. New findings at Georgia Tech, published in January during Glaucoma Awareness Month, explore one of the many molecular origins of glaucoma and advance research dedicated to fighting the disease.

Erlotinib better for treatment of non-small cell lung cancers

Researchers at Johns Hopkins have shown that DNA changes in a gene that drives the growth of a form of lung cancer can make the cancer's cells resistant to cancer drugs.

Third-party to prepare FDA submittals for NanoLogix

NanoLogix Inc., an innovator in the accelerated detection, identification and antibiotic sensitivity determination of live bacteria announces that has instructed a third-party to prepare a total of six applications for submittal to the US FDA.

Scientists can now observe enhancer activity in real embryo

As an embryo develops, different genes are turned on in different cells, to form muscles, neurons and other bodily parts. Inside each cell's nucleus, genetic sequences known as enhancers act like remote controls, switching genes on and off. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, can now see - and predict - exactly when each remote control is itself activated, in a real embryo.

Researchers crack structure and function of malarial protein

A biology lab at Washington University has just cracked the structure and function of a protein that plays a key role in the life of a parasite that killed 655,000 people in 2010.

Amyloid precursor protein fragment may be a biomarker for autism

Immune system abnormalities that mimic those seen with autism spectrum disorders have been linked to the amyloid precursor protein (APP), reports a research team from the University of South Florida's Department of Psychiatry and the Silver Child Development Center.

Alteration in ISG15 pathway triggers breast cancer metastasis

Research led by Shyamal Desai, PhD, Assistant Professor of Biochemistry and Molecular Biology at LSU Health Sciences Center New Orleans, has discovered a key change in the body's defense system that increases the potential for breast cancer to spread to other parts of the body.

Researchers decode and characterize DNA repair mechanism

Oxidative stress is the cause of many serious diseases such as cancer, Alzheimer's, arteriosclerosis and diabetes. It occurs when the body is exposed to excessive amounts of electrically charged, aggressive oxygen compounds. These are normally produced during breathing and other metabolic processes, but also in the case of ongoing stress, exposure to UV light or X-rays. If the oxidative stress is too high, it overwhelms the body's natural defences. The aggressive oxygen compounds destroy genetic material, resulting in what are referred to as harmful 8-oxo-guanine base mutations in the DNA.

AAA announces recipients of Young Investigator Awards

The American Association of Anatomist's (AAA) Young Investigator Awards combine three long-standing AAA awards-Bensley, Herrick, and Mossman-with the recently established Morphological Sciences Award, all recognizing investigators in the early stages of their careers who have made important contributions to biomedical science through their research in cell/molecular biology, developmental biology, comparative neuroanatomy, or the morphological sciences.

Biologists develop radar to track ADAR's RNA editing activity in neurons

To track what they can't see, pilots look to the green glow of the radar screen. Now biologists monitoring gene expression, individual variation, and disease have a glowing green indicator of their own: Brown University biologists have developed a "radar" for tracking ADAR, a crucial enzyme for editing RNA in the nervous system.
