Decision-making over 'sacred values' prompts a distinct cognitive process

An Emory University neuro-imaging study shows that personal values that people refuse to disavow, even when offered cash to do so, are processed differently in the brain than those values that are willingly sold.

Duke team creates vaccine adjuvant of nanoparticles that target lymph nodes

Researchers at Duke University Medical Center have created synthetic nanoparticles that target lymph nodes and greatly boost vaccine responses, said lead author Ashley St. John, Ph.D., a researcher at Duke-NUS Graduate Medical School.

Researchers discover new mechanism that regulates blood pressure

Analyzing all the genes of dozens of people suffering from a rare form of hypertension, Yale University researchers have discovered a new mechanism that regulates the blood pressure of all humans.

Scientists use metabolomics to discover DMS linked with neuropathic pain

Millions of people worldwide suffer from a type of chronic pain called neuropathic pain, which is triggered by nerve damage. Precisely how this pain persists has been a mystery, and current treatments are largely ineffective. But a team led by scientists from The Scripps Research Institute, using a new approach known as metabolomics, has now discovered a major clue: dimethylsphingosine (DMS), a small-molecule byproduct of cellular membranes in the nervous system.

Study describes new pharmacological resistance to colon cancer

Doctors and researchers of Hospital del Mar and its research institute, the IMIM, have lead a study describing a new pharmacological resistance to cancer. This new mechanism is a mutation in an oncogene called EGFR (epidermal growth factor receptor) causing resistance to treatment using a drug called cetuximab, a monoclonal antibody which specifically attacks the EGFR.

Scientists discover finely tuned mechanism associated with CHD

Scientists at the Gladstone Institutes have identified a finely tuned mechanism by which fetal heart muscle develops into a healthy and fully formed beating heart-offering new insight into the genetic causes of congenital heart disease and opening the door to one day developing therapies to fight this chronic and potentially fatal disorder.

Chronic inflammation combines with DNA methylation to promote development of colorectal cancer

Chronic inflammation combines with DNA methylation, a process that shuts down cancer-fighting genes, to promote development of colorectal cancer, scientists at The University of Texas MD Anderson Cancer Center report today in the advance online publication of the journal Nature Medicine.

Researchers create first 3D structure of key cancer protein

Cancer Research UK scientists have created the first 3D structure of a key protein that protects against the development of cancer, according to research published in Nature Structural & Molecular Biology today.

Three-parent children may be born in near future in an effort to combat mitochondrial diseases

In the next couple of years the scientific community may witness creation of children with genetic material from three parents. British scientists want to start testing a new IVF technique to try to eradicate incurable genetic diseases such as muscular dystrophy. The concept took a leap forward yesterday after the Government announced a public consultation on whether the law should be changed to allow the technique.

IMB announces new International Summer School in the Life Sciences

The Institute of Molecular Biology (IMB) has announced a new International Summer School (ISS) in the Life Sciences. The ISS will take place from 16th July to 24th August 2012 and will provide outstanding and enthusiastic undergraduate, Master's and PhD students the opportunity to undertake exciting research projects.

First genome-wide study of high-altitude adaptations in Ethiopians

Over many generations, people living in the high-altitude regions of the Andes or on the Tibetan Plateau have adapted to life in low-oxygen conditions. Living with such a distinct and powerful selective pressure has made these populations a textbook example of evolution in action, but exactly how their genes convey a survival advantage remains an open question. Now, a University of Pennsylvania team has made new inroads to answering this question with the first genome-wide study of high-altitude adaptations within the third major population to possess them: the Amhara people of the Ethiopian Highlands.

Scientists develop new way to create electromagnetic T-rays for medical scanners

Scientists have developed a new way to create electromagnetic Terahertz (THz) waves or T-rays - the technology behind full-body security scanners. The researchers behind the study, published recently in the journal Nature Photonics, say their new stronger and more efficient continuous wave T-rays could be used to make better medical scanning gadgets and may one day lead to innovations similar to the 'tricorder' scanner used in Star Trek.

RBC storage duration not associated with transfusion-related pulmonary complications

There is no difference in early measures of pulmonary function, immunologic status or coagulation status after fresh versus standard issue single-unit red blood cell (RBC) transfusion, according to a new study from the Mayo Clinic.

NCI-funded project aims to shed new light on implications for bone metastasis in prostate cancer

Prostate cancer is the most frequent and second deadliest cancer men face. A team of Wayne State University researchers recently received $363,660 from the National Cancer Institute of the National Institutes of Health for the project - "Bone-induced c-kit in prostate cancer cells: implications for bone metastasis" - that aims to shed new light on implications for bone metastasis in prostate cancer.

Exercise fails to improve glucose metabolism in autophagy-deficient mice

The health benefits of exercise on blood sugar metabolism may come from the body's ability to devour itself, UT Southwestern Medical Center researchers report in the journal Nature.

Minuscule amounts of ethanol can double C. elegans' life span

Minuscule amounts of ethanol, the type of alcohol found in alcoholic beverages, can more than double the life span of a tiny worm known as Caenorhabditis elegans, which is used frequently as a model in aging studies, UCLA biochemists report. The scientists said they find their discovery difficult to explain.

Ambiguity makes language more efficient

Why did language evolve? While the answer might seem obvious - as a way for individuals to exchange information - linguists and other students of communication have debated this question for years. Many prominent linguists, including MIT's Noam Chomsky, have argued that language is, in fact, poorly designed for communication.

ARCA biopharma receives method patent for treatment with bucindolol based on genetic targeting

ARCA biopharma, Inc., a biopharmaceutical company developing genetically targeted therapies for cardiovascular diseases, today announced that the U.S. Patent and Trademark Office has issued a patent on methods for determining whether to administer or prescribe bucindolol to a patient based on whether the patient has a specific genotype - homozygous for the arginine 389 polymorphism in the beta-1 adrenergic receptor.

Combination of gefitinib and miRNA-inhibitor might effectively treat NSCLC

New research published in Nature Medicine indicates that targeted drugs such as gefitinib might more effectively treat non-small cell lung cancer if they could be combined with agents that block certain microRNAs.

Novel imaging platform reveals new details on aggressive cancer development

When cancers become aggressive and spread they are the most deadly. Unfortunately, little is known about how to stop this development. A new imaging platform developed by Lawson Health Research Institute's Drs. Ann Chambers and John Lewis is providing insight into just that - the exact moment when cancer cells turn deadly.
