Search for genes tied to social behavior

The first genome-wide search for genes governing social behavior has found that even the simplest social creatures - the amoebae Dictyostelium discoideum - have more than 100 genes that help regulate their cooperative behavior.

Location location location, even for genes

Moving an active gene from the interior of the nucleus to its periphery can inactivate that gene report scientists from the University of Chicago Medical Center in an article to be published early online Feb.13, 2008, in the journal Nature.

Researchers use embryonic stem cells to develop functioning immune system blood cells

For the first time, researchers have used embryonic stem cells to develop functioning immune system blood cells -- an important step in eventually using embryonic stem cells as an alternative source of cells for traditional bone marrow transplantations.

Bacterial toxin closes gate on immune response

Researchers at the University of Pennsylvania School of Medicine have demonstrated that a bacterial toxin from the common bacterium Staphylococcus aureus shuts down the control mechanism of the tunnel, called an ion channel, in immune cell membranes.

Maslinic acid from olives shows anti-cancer properties

A research group of the University of Granada has found out that maslinic acid, a compound present in the leaf and the olive skin wax extracted from alpeorujo (crushed olive pulp), has the capacity of preventing cancer as well as regulating apoptosis in carcinogenic processes.

Discovery of 'overdrive' protein could broaden drug design options

New research by scientists at the University of North Carolina at Chapel Hill shows for the first time that an important family of proteins known to function at the cell surface also functions at a site within the cell.

Night-time noise from aircraft or traffic can increase a person's blood pressure

Scientists from Imperial College London and other European institutions monitored 140 sleeping volunteers in their homes near London Heathrow and three other major European airports.

Discovery that embryonic stem cells can be used to create functional immune system blood cells

A new study demonstrates for the first time that embryonic stem cells can be used to create functional immune system blood cells, a finding which is an important step in the utilization of embryonic stem cells as an alternative source of cells for bone marrow transplantation.

Some cases of autism may be traced to the immune system of mothers during pregnancy

New research from the UC Davis M.I.N.D. Institute and Center for Children's Environmental Health has found that antibodies in the blood of mothers of children with autism bind to fetal brain cells, potentially interrupting healthy brain development.

Potential method for repairing misspelling in DNA code that causes spinal muscular atrophy

Researchers at the University of Delaware have discovered a novel technique - that acts like a "spell-checker" for correcting a misspelling in the DNA code - to repair the defective gene that causes spinal muscular atrophy (SMA).

Discovery of previously unknown mechanism that leads to cleft palate

By creating a genetic mutation in zebrafish, University of Oregon scientists say they've discovered a previously unknown mechanism for cleft palate, a common birth defect in humans that has challenged medical professionals for centuries.

Alpha-linolenic acid good for dry eye syndrome

Research conducted by Massachusetts Eye and Ear Infirmary (MEEI) Cornea Service Director and Harvard Medical School Professor Reza Dana, M.D., M. Sc., MPH, and colleagues at the Schepens Eye Research Institute have found for the first time that topical drop application of alpha-linolenic acid (ALA) led to a significant decrease in clinical signs of dry eye syndrome (DES) in animal models.

Hostility plus depression elevates risk for heart disease

Researchers led by Jesse Stewart, Ph.D., assistant professor of psychology at Indiana University-Purdue University Indianapolis, report that hostility and depression appear to act together in a complex way to elevate inflammatory proteins in the human body, possibly putting hostility plus depression on the list of risk factors for heart disease along with high blood pressure, elevated cholesterol, and smoking.

Discovery of possible target for prevention and treatment of pneumonia

Researchers at Children's Hospital of Pittsburgh of UPMC have identified a key protein target that may be a crucial factor in the development of a vaccine to prevent and new therapies to treat pneumonia, the leading killer of children worldwide.
