Although genetic factors contribute to congenital heart disease, many children born with heart defects have healthy parents and siblings, suggesting that new mutations that arise spontaneously —- known as de novo mutations —- might contribute to the disease. New research shows that about 10 percent...

The gardener's best friend, the earthworm, is great at protecting leaves from being chomped by slugs, suggests research in BioMed Central's open access journal BMC Ecology. Although they lurk in the soil, they seem to protect the plants above ground. Increasing plant diversity also decreases the...

Almost two-thirds of common plants and half the animals could see a dramatic decline this century due to climate change -- according to research from the University of East Anglia. But acting quickly to mitigate climate change could reduce losses by 60 percent and buy an additional 40 years for...

Total anomalous pulmonary venous connection, one type of "blue baby" syndrome, is a potentially deadly congenital disorder that occurs when pulmonary veins don't connect normally to the left atrium of the heart. TAPVC babies are born cyanotic from lack of oxygen. Semaphorin 3d guides the development of endothelial cells and is...

Every year, thousands of babies are born with severely malformed hearts, disorders known collectively as congenital heart disease. New research shows that about 10 percent of these defects are caused by genetic mutations that are absent in the parents of affected children. Fuente :...
