Tuberculosis genomes recovered from 200-year-old Hungarian mummy 2013-07-24

By University of Warwick

Researchers have recovered tuberculosis (TB) genomes from the lung tissue of a 215-year old mummy using a technique known as metagenomics.

Failure to destroy toxic protein -- not buildup of protein itself -- contributes to Huntington's disease 2013-07-24

By NIH/National Institute of Neurological Disorders and Stroke

Recycling is not only good for the environment, it's good for the brain. A study using rat cells indicates that quickly clearing out defective proteins in the brain may prevent loss of brain cells.

Protein complex linked to cancer growth may also help fight tumors 2013-07-24

By Moffitt Cancer Center

Researchers have discovered a gene expression signature that may lead to new immune therapies for lung cancer patients. They found that NF-κB, a protein complex known to promote tumor growth, may also have the ability to boost the immune system t

Complete description of gene expression in the human retina 2013-07-24

By Massachusetts Eye and Ear Infirmary

Investigators have published the most thorough description of gene expression in the human retina reported to date.

Monitoring nutrient intake can help vegetarian athletes stay competitive 2013-07-24

By Institute of Food Technologists (IFT)

A balanced plant-based diet provides the same quality of fuel for athletes as a meat-based diet, provided vegetarians seek out other sources of certain nutrients that are more commonly found in animal products, according to new research.

Multiple sclerosis drug shows promise for preventing heart failure 2013-07-24

By University of Illinois at Chicago

A drug already approved to treat multiple sclerosis may also hold promise for treating cardiac hypertrophy, or thickening of the cardiac muscle -- a disorder that often leads to heart failure, researchers report.

Drug research: New technique shows if drugs have reached intended target 2013-07-24

By Nanyang Technological University

The search for new drugs, including those for cancer, is set to speed up thanks to a new research technique which could tell if drugs had reached their intended target.

New approach to treat the most common heart valve disease in Western countries 2013-07-24

By Montreal Heart Institute

Scientists have developed a new approach to treat aortic valve stenosis through the administration of a compound that prevents valve deterioration and can even reverse the progression of the disease. It is the most common type of heart valve disease in We

Joint custody? Overnights away from home affect children's attachments 2013-07-24

By University of Virginia

In joint custody arrangements, infants who spent overnights away from their mothers had less attachment to their mothers, a new study shows.

Haste and waste on neuronal pathways 2013-07-24

By ETH Zurich

Researchers were able to measure the speed of neuronal signal conduction along segments of single axons in neuronal cultures by using a high-resolution electrical method. The bioengineers are now searching for plausible explanations for the large conducti

Cost of treating dizziness in the emergency room soars 2013-07-24

By Johns Hopkins Medicine

Emergency room visits for severe dizziness have grown exponentially in recent years, with costs topping $3.9 billion in 2011 and projected to reach $4.4 billion by 2015. The investigators say roughly half a billion a year could be saved im

Missed diagnoses and drug errors make up bulk of primary care malpractice claims 2013-07-24

By BMJ-British Medical Journal

Missed diagnoses -- particularly of cancer, heart attack, and meningitis -- and drug errors make up the bulk of malpractice claims brought against doctors in primary care, finds a new analysis.

Scientists find 3-D structure of key drug target for diabetes 2013-07-24

By The Scripps Research Institute

Scientists have determined and analyzed the three-dimensional atomic structure of the human glucagon receptor. The receptor, found mainly on liver and kidney cells, helps regulate glucose levels in the bloodstream and is the target of potential therapeuti

Genomic imprinting maintains a reserve pool of blood-forming stem cells in mouse bone marrow 2013-07-24

By Stowers Institute for Medical Research

Hematopoietic stem cells -- bone marrow-derived adult stem cells that give rise to the wide variety of specialized blood cells -- come in two flavors: the reserve force sits quietly waiting to be called upon while the active arm continually proliferates s

A heart of gold: Gold nanofibers in engineered heart tissue can enhance electrical signalling 2013-07-24

By American Friends of Tel Aviv University

Scientists have integrated cardiac cells with nanofibers made of real gold particles to create functional engineered cardiac tissues. With the gold particles, these tissues contract much faster and stronger as a whole, he reports, making them more viable

Protein responsible for 'bad' blood vessel growth discovered 2013-07-24

By University College London

The discovery of a protein that encourages blood vessel growth, and especially "bad" blood vessels -- the kind that characterize diseases as diverse as cancer, age-related macular degeneration and rheumatoid arthritis -- has been reported.

How smoking increases vulnerability to alcohol abuse 2013-07-24

By Cell Press

Smoking is a well-known risk factor for subsequent alcohol abuse, but the mechanisms underlying this link are unknown. Now researchers show in a study conducted in rats that even a single exposure to nicotine temporarily changes how the brain's reward sys
