New research into the treatment of Alzheimer's disease reports improvement in language abilities using a novel immune-based approach. A video accompanying the research, published today in the open access journal BMC Neurology, documents rapid language improvement within minutes of using this new treatment.

Building on previous work by the same authors, published in BioMed Central's Journal of Neuroinflammation, this study focuses on the effect of the anti-tumor necrosis factor–alpha (TNF-alpha) drug, etanercept, on measures of verbal ability.

The white horse is an icon for dignity which has had a huge impact on human culture across the world. An international team led by researchers at Uppsala University has now identified the mutation causing this spectacular trait and show that white horses carry an identical mutation that can be traced back to a common ancestor that lived thousands of years ago. The study is interesting for medical research since this mutation also enhance the risk for melanoma. The paper is published on July 20 on the website of Nature Genetics.

Leading world scientists convene in Brazil July 21-25 amid growing concern that evaporation and ongoing destruction of world wetlands, which hold a volume of carbon similar to that in the atmosphere today, could cause them to exhale billows of greenhouse gases.

A study performed by researchers at the Institute for Research in Biomedicine (IRB Barcelona), in collaboration with researchers at the Instituto de Biología Molecular of the CSIC, reveal a mechanism that controls the movement of cells in a tissue by regulating cell adhesion. This same mechanism may be defective in diseases such as cancer and its metastasis, when tumour cells lose their adhesion to neighbouring cells and migrate through the organism. The results of this research have been published in this week's Nature Cell Biology.

STANFORD, Calif. - The study of dark-skinned mice has led to a surprising finding about a common protein involved in tumor suppression, report researchers at the Stanford University School of Medicine. The results may lead to new treatments for bone marrow failure in humans.

A way to turn off one gene at a time has earned acceptance in biology laboratories over the last decade. Doctors envision the technique, called RNA interference, as a tool to treat a variety of diseases if it can be adapted to humans.

Emory University researchers have discovered that antibiotics known as fluoroquinolones can make RNA interference more effective in the laboratory and reduce potential side effects. The results will be published online this week in the journal Nature Biotechnology.

LA JOLLA, CA — Logic says it has to be the niche. As air and water preceded life, so the niche, that hospitable environment that shelters adult stem cells in many tissues and provides factors necessary to keep them young and vital, must have emerged before its stem cell dependents.

DURHAM, N.C. – When it comes to stenting – using metal tubes to prop open blocked arteries – physicians are continuing to choose to gain entry to the circulatory system through an opening in the leg instead of the arm, even though the latter option appears to be safer, with fewer side effects, say researchers at Duke Clinical Research Institute.

DURHAM, N.C. – A new study from Duke University Medical Center finds that patients treated solely with medications after suffering from chest pain, heart attack or coronary artery disease are more likely to die during the first year following their initial hospitalization.
