Molecular Biology News and Research

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.

New dimension discovered in body clock rhythm

Research on what makes the body clock tick has led Dr Michael Hastings of the MRC Laboratory of Molecular Biology in Cambridge to discover a new and unanticipated cog in the human body clock. A patent for the compound involved has been filed by MRC Technology. The results, published in Science, could lead to therapies for people whose sleep is disrupted by shift work or old age.

Plants deliver: biofuels, medicines, bioplastics, flavours, pigments...

The need for a renewable and affordable source of carbon that can sustain future economic development without negatively impacting the environment is now widely recognised. It is also apparent that the increasingly high demand for fossil carbon will eventually deplete existing stocks.

Shift in HIV prevention priorities needed - reducing multiple sexual partnerships and providing male circumcision services should be emphasized

According to a new policy analysis led by researchers at the Harvard School of Public Health (HSPH) and the University of California, Berkeley, the most common HIV prevention strategies-condom promotion, HIV testing, treatment of other sexually transmitted infections (STIs), vaccine and microbicide research, and abstinence-are having a limited impact on the predominantly heterosexual epidemics found in Africa.

Scientists identify key roadblock to gene expression

A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster. The work identifies a critical stop sign for transcription, the first step in gene expression, and has implications for understanding how the AIDS virus regulates its genes. The findings will be published in the 15 May 2008 issue of the journal Nature

The design of a vaccine against Leishmaniasis

The parasitology team at the "Severo Ochoa" Molecular biology centre (CSIC-UAM) has focused its research efforts on the search for a vaccine capable of activating immunity against the parasite that causes leishmaniasis.

Killer competition: neurons duke it out for survival!

The developing nervous system makes far more nerve cells than are needed to ensure target organs and tissues are properly connected to the nervous system. As nerves connect to target organs, they somehow compete with each other resulting in some living and some dying.

Erythropoietin gene linked to severe diabetic eye, kidney diseases

Researchers at the John A. Moran Eye Center at the University of Utah and collaborative institutions have identified a gene called erythropoietin (EPO) that contributes to increased risk of severe diabetic eye and kidney diseases, called retinopathy and nephropathy.

Scientists discover the double life of proteins

Scientists at The Australian National University are a step closer to understanding the rare Hartnup disorder after discovering a surprising link between blood pressure regulation and nutrition that could also help to shed light on intestinal and kidney function.

Scientists determine molecular structures of bacterial AlkB protein and its corresponding human protein, ABH2

A team of University of Chicago scientists has shown how two proteins locate and repair damaged genetic material inside cells.

Interaction networks: the new path to drug discovery

Although the pharmaceutical industry has dedicated enormous research efforts over the last 50 years to identify new targets and develop new active ingredients, these efforts have met with limited success.

Cutting-edge surgical training facility to open at the University of Sydney

A new facility for the training of the next generation of microsurgeons in both molecular biology and advanced surgical techniques will be officially opened by the Governor of NSW, Her Excellency Professor Marie Bashir AC CVO, at the University of Sydney on Tuesday 22 April.

New mucosal vaccine against anthrax effective in early tests

Early studies show that a new mucosal vaccine against anthrax has the potential to provide military personnel with more effective and efficient protection against a "popular" bioweapon, according to a study published in the journal Clinical and Vaccine Immunology (CVI).

Mosquito mating mechanism could lead to new attack on dengue and yellow fever

Cornell researchers have identified a mating mechanism that possibly could be adapted to prevent female mosquitoes from spreading the viruses that cause dengue fever, second only to malaria as the most virulent mosquito-borne disease in the tropical world.

Diabetes drug may hold potential as treatment for epilepsy, using same mechanism as ketogenic diet

Two years ago, University of Wisconsin-Madison scientists reported they had suppressed epileptic seizures in rats by giving them a glycolytic-inhibitor, inhibiting the brain's ability to turn sugar into excess energy and blocking the expression of seizure-related genes.

New mouse model grants insight into the genetic and molecular mechanisms underpinning acute myeloid leukemia

Leukaemia - cancer of blood or bone marrow is caused by mutations that allow defective blood cells to accumulate and displace healthy blood.

1/3 of risk for dementia attributable to small vessel disease, autopsy study shows

Alzheimer's disease may be what most people fear as they grow older, but autopsy data from a long-range study of 3,400 men and women in the Seattle region found that the brains of a third of those who had become demented before death showed evidence of small vessel damage: the type of small, cumulative injury that can come from hypertension or diabetes.
