Discovery of new class of non-protein coding genes in mammals with key functions

A research team at the Broad Institute of Harvard and MIT and Beth Israel Deaconess Medical Center has uncovered a vast new class of previously unrecognized mammalian genes that do not encode proteins, but instead function as long RNA molecules.

Waging war on tropical diseases may be key to U.S. foreign policy

Stating that neglected tropical diseases (NTDs) not only promote poverty but also destabilize communities, former Health and Human Services Secretary Tommy Thompson and Sabin Vaccine Institute President Peter Hotez call upon the public-health and foreign-policy communities to embrace medical diplomacy and NTD control as a means to combat terrorism in an article published January 27 in the open-access journal PLoS Neglected Tropical Diseases.

New understanding of RNA and evolution

With the aid of a straightforward experiment, researchers have provided some clues to one of biology's most complex questions: how ancient organic molecules came together to form the basis of life.

Schizophrenia and autism may share common origin

Schizophrenia and autism probably share a common origin, hypothesises Dutch researcher Annemie Ploeger following an extensive literature study.

Six new gene variations linked to increased BMI

A genetic study of more than 90,000 people has identified six new genetic variants that are associated with increased Body Mass Index (BMI), the most commonly used measure of obesity.

Researchers reveal a new aspect of tumor development

The DNA in our cells is constantly under assault from oxygen, the sun's radiation and environmental stresses.

Scientists discover new compounds to target muscular dystrophy

Using a drug-discovery technique in which molecules compete against each other for access to the target - the strand of toxic RNA that causes the most common form of muscular dystrophy in adults - a team at the University of Rochester Medical Center has identified several compounds that, in the laboratory, block the unwanted coupling of two molecules that is at the root of the disease.

Computers used to create predictive models of human disease

Increased use of computers to create predictive models of human disease is likely following a workshop organised by the European Science Foundation (ESF), which urged for a collaborative effort between specialists in the field.

Scientists sequence genome of a cancer patient

For the first time, scientists have decoded the complete DNA of a cancer patient and traced her disease - acute myelogenous leukemia - to its genetic roots.

Alternative splicing in genes more prevalent than previously believed

Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA.

Researchers discover how Sonic hedgehog gene controls brain development

University of Pennsylvania School of Medicine researchers have discovered how the expression of the Sonic hedgehog gene is regulated during brain development and how mutations that alter this process cause brain malformations. The results appear online this month in Nature Genetics.

Getting the flu early may protect against worse one later

New evidence about the worldwide influenza pandemic of 1918-1919 indicates that getting the flu early protected many people against a second deadlier wave, an article co-authored by an NIH epidemiologist concludes.

Molecule stops DNA replication in its tracks

When a dividing cell duplicates its genetic material, a molecular machine called a sliding clamp travels along the DNA double helix, tethering the proteins that perform the replication.

Ultrafast photodynamics of DNA

DNA, the molecule that acts as the carrier of genetic information in all forms of life, is highly resistant against alteration by ultraviolet light, but understanding the mechanism for its photostability presents some puzzling problems. A key aspect is the interaction between the four chemical bases that make up the DNA molecule.

Discovery of gene variant for cleft lip

About 20 percent of isolated cleft lip, one of the world's most common birth defects, may be due to a one-letter difference in the DNA sequence of a gene involved in facial development, researchers supported by the National Institutes of Health report.

Bacterial pneumonia caused most deaths in 1918 influenza pandemic

The majority of deaths during the influenza pandemic of 1918-1919 were not caused by the influenza virus acting alone, report researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Instead, most victims succumbed to bacterial pneumonia following influenza virus infection.
