Molecular Biology News and Research

RSS

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.

Scientists pinpoint mechanism essential for memory formation

Now, in a study that appears in the May 10, 2012 issue of the journal Neuron, scientists from the Florida campus of The Scripps Research Institute have pinpointed a mechanism that is essential for forming memories in the first place and, as it turns out, is equally essential for eliminating them after memories have formed.

G&D, IAVI and GMI partner to develop new HIV/AIDS vaccine

The International AIDS Vaccine Initiative (IAVI), GlycoMimetics, Inc. (GMI), and Glycosensors and Diagnostics, LLC (G&D) today announced a collaboration to develop an AIDS vaccine using novel compounds that mimic carbohydrates, called glycomimetics.

'Good' cholesterol may not protect against coronary heart disease

A new study by Harvard School of Public Health (HSPH) researchers has found that a subclass of high-density lipoprotein (HDL) cholesterol, the so-called "good" cholesterol, may not protect against coronary heart disease (CHD) and in fact may be harmful.

Automated way to record electrical activity inside neurons in the living brain

Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned on at a given moment. However, achieving this entry is such a painstaking task that it is considered an art form; it is so difficult to learn that only a small number of labs in the world practice it.

New system measures strength of communication between muscle cells and motor neurons

In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure the communication between stem cell-derived motor neurons and muscle cells in a Petri dish.

Dilp8 provides an important signal to slow body growth and delay insect development

Two independent groups of researchers have identified a hormone that is responsible for keeping the growth and development of insects on track. The results, which are reported in the journal Science, suggest that Dilp8 provides an important signal to slow body growth and delay insect development.

HSPH introduces Obesity Prevention Source website

What is causing the obesity epidemic-and how can we stop and reverse this worldwide weight problem? A new website offers authoritative answers to these pressing questions and sheds light on one of the most challenging public health threats of our time.

Scientists identify how cell architecture changes during formation of gametes

Scientists using high-powered microscopes have made a stunning observation of the architecture within a cell - and identified for the first time how the architecture changes during the formation of gametes, also known as sex cells, in order to successfully complete the process.

Researchers discover how protein ARTD1's DNA recruitment is regulated during inflammation

During inflammation, controlled gene expression is necessary in order to allow the organism to mount an effective defense response. For this process, the protein ARTD1 is removed from the DNA.

Cancer genomes in a common database and computation of disease drivers

The emerging field of "personalized" or "precision" medicine holds great promise in the fight against cancer. If scientists can identify the genetic changes that drive each patient's cancer cells, they can use that information to develop targeted treatments. But achieving this goal will require massive amounts of genomic and clinical data and a sophisticated infrastructure to manage and analyze the data.

Vitamin D strengthens innate immunity against viral infections

Vitamin D may be known as the sunshine vitamin, but a new research report appearing in the Journal of Leukocyte Biology shows that it is more than that. According to the report, insufficient levels of vitamin D are related to a deficiency in our innate immune defenses that protect us from infections, neoplasias or autoimmune diseases.

Researchers define structure of key part of human obesity receptor

Medical researchers at the University of Sheffield have defined the structure of a key part of the human obesity receptor- an essential factor in the regulation of body fat- which could help provide new treatments for the complications of obesity and anorexia.

Heart can regulate energy balance throughout the body

UT Southwestern Medical Center researchers have demonstrated for the first time that the heart can regulate energy balance throughout the body, a finding that may point to more effective treatments for obesity, diabetes, and heart disease.

AAA to gather for anatomy meeting in conjunction with Experimental Biology 2012

The American Association of Anatomists will gather this week for its annual meeting in conjunction with the Experimental Biology 2012 conference, which will draw more than 14,000 scientists from industry, government and academia. Below are some programming highlights for the anatomy meeting. All presentations will be made at the San Diego Convention Center.

Fragile-X gene linked with disrupting de novo mutations in children with autism

A team led by scientists at Cold Spring Harbor Laboratory (CSHL) publishes research today indicating a striking association between genes found disrupted in children with autism and genes that are targets of FMRP, the protein generated by the gene FMR1, whose dysfunction causes Fragile-X syndrome.

Study shows how PCBs could add to autism risk

New research from UC Davis and Washington State University shows that PCBs, or polychlorinated biphenyls, launch a cellular chain of events that leads to an overabundance of dendrites - the filament-like projections that conduct electrochemical signals between neurons - and disrupts normal patterns of neuronal connections in the brain.

Physical activity reduces oxidative stress in people with SCT

Sickle cell disease (SCD), an inherited condition that causes red blood cells to sometimes deform into a crescent shape, affects an estimated 100,000 Americans, typically those of African descent. However, far more have sickle cell trait (SCT), caused when individuals carry just a single copy of the disease-causing mutation in their genes.
