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.

Insulin degludec has reduced risk of recurrent hypoglycemia than insulin glargine

Insulin degludec (Tresiba), a new ultra-long-acting insulin, has a similar or reduced risk of recurrent hypoglycemia—low blood sugar—compared with the commercially available insulin glargine, a new meta-analysis study finds. [More]

Scientists find new biomarker to accurately measure long-term sugar intake from blood or hair sample

FAIRBANKS, Alaska-Scientists at the University of Alaska Fairbanks identified a new tool that can dramatically improve the notoriously inaccurate surveys of what and how much an individual eats and drinks. Their research is published in the June 2013 issue of the Journal of Nutrition. [More]
FGF21 endocrine hormone which reduces glucose levels also protects against cardiac diseases in mice

FGF21 endocrine hormone which reduces glucose levels also protects against cardiac diseases in mice

A research group has found that FGF21, an endocrine factor which reduces glucose levels, protects against cardiac diseases in mice. The research, published online on the journal Nature Communications, was led by Francesc Villarroya, professor from the Department of Biochemistry and Molecular Biology of the UB and Director of the Institute of Biomedicine of the University of Barcelona (IBUB), affiliated centre with the campus of international excellence BKC.

International researchers solve three-dimensional structure of respiratory syncytial virus

Young children and the elderly are especially susceptible to respiratory syncytial virus. The three-dimensional structure of respiratory syncytial virus has been solved by an international team from Finland and Switzerland. [More]
Comparison of 1,000-year-old and modern bacterial genomes provides insights into history of leprosy pathogen

Comparison of 1,000-year-old and modern bacterial genomes provides insights into history of leprosy pathogen

From skeletons and biopsies, an international team of scientists was successful in reconstructing a dozen medieval and modern genomes of the leprosy-causing bacteria Mycobacterium leprae. [More]
CSHL scientists solve the mystery of why some infants born with grave syndrome

CSHL scientists solve the mystery of why some infants born with grave syndrome

By identifying a protein that acts as a genetic modifier, scientists at Cold Spring Harbor Laboratory have solved the mystery of why some infants are born with a grave syndrome consisting of cleft palate and major deformities of the skin and limbs, while other infants bearing the same predisposing genetic mutation bear little or no sign of the illness, called EEC.

Non-invasive odor analysis: A valuable technique for early diagnosis of melanoma

Non-invasive odor analysis: A valuable technique for early diagnosis of melanoma

According to new research from the Monell Center and collaborating institutions, odors from human skin cells can be used to identify melanoma, the deadliest form of skin cancer. In addition to detecting a unique odor signature associated with melanoma cells, the researchers also demonstrated that a nanotechnology-based sensor could reliably differentiate melanoma cells from normal skin cells.

Tumor suppressor p53 inactivation and restoration: an interview with Dr. Xin Lu, Ludwig Institute for Cancer Research

Tumor suppressor p53 inactivation and restoration: an interview with Dr. Xin Lu, Ludwig Institute for Cancer Research

Before we talk about p53, it is important to understand why cancer cells are a problem for the body. Cancer cells multiply recklessly, refuse to die and blithely metastasize to set up shop in places where they don’t belong. [More]
TSRI scientists identify key triggers of cancer-blocking mechanism in cells

TSRI scientists identify key triggers of cancer-blocking mechanism in cells

Scientists at The Scripps Research Institute have identified key triggers of an important cancer-blocking mechanism in cells. [More]

Study sheds light on origin of wide range of brain disorders

Study sheds light on origin of wide range of brain disorders

Researchers at Weill Cornell Medical College have uncovered a mechanism that guides the exquisite wiring of neural circuits in a developing brain -- gaining unprecedented insight into the faulty circuits that may lead to brain disorders ranging from autism to mental retardation. [More]
Human Argonautes directly cuts messenger RNA

Human Argonautes directly cuts messenger RNA

Human Argonautes (hAgo), are key proteins involved in a process known as RNA interference. RNAi, as it is often called, is a mechanism that cells use to regulate gene expression. [More]
Cow antibodies points to new ways for making human medicines

Cow antibodies points to new ways for making human medicines

Humans have been raising cows for their meat, hides and milk for millennia. Now it appears that the cow immune system also has something to offer. A new study led by scientists from The Scripps Research Institute (TSRI) focusing on an extraordinary family of cow antibodies points to new ways to make human medicines. [More]

Researchers demonstrate how young genes acquire essential functions

Researchers from UConn and other institutions in the U.S. and abroad have shown how a relatively young gene can acquire a new function and become essential to an organism's life. [More]
Changes in normal glycan behavior lead to fatal lysosomal disease, say researchers

Changes in normal glycan behavior lead to fatal lysosomal disease, say researchers

From the neurons that enable thought to the keratinocytes that make toenails grow-a complex canopy of sugar molecules, commonly known as glycans, envelop every living cell in the human body. [More]
Genetic duplication that occurred millions of years ago encouraged evolution of ASF1b gene: Study

Genetic duplication that occurred millions of years ago encouraged evolution of ASF1b gene: Study

How and when evolution generates diversity or gives form to proteins, living beings' functional building blocks, are essential questions that still surround the theory of evolution. In humans, the majority of genes have emerged via genetic duplication, a strategy in which a gene generates two identical copies that can evolve to generate different proteins. [More]
New technique selectively represses unwanted immune reactions without disabling immune system

New technique selectively represses unwanted immune reactions without disabling immune system

The human immune system is remarkably efficient, but sometimes its attack is misdirected, leading to allergies, autoimmune diseases and rejection of transplant organs and therapeutic drugs. Current immune suppressants have major drawbacks, but a team from The Scripps Research Institute (TSRI) has demonstrated a new technique that may lead to a better way to selectively repress unwanted immune reactions without disabling the immune system as a whole.
