New cause of life-threatening disease identified Posted: 08 Jun 2013 05:45 PM PDT Researchers have just published findings that explain a previously unknown mechanism used by cells to communicate with one another. The research significantly contributes to understanding why some children are born with malformations and why children and adults may develop life-threatening diseases.

Rare mitochondrial mutations –- maybe not so rare? Comprehensive analysis of mitochondrial DNA will aid early diagnosis Posted: 08 Jun 2013 05:44 PM PDT Scientists have discovered that supposedly rare mutations in the mitochondria, the 'power plants' of human cells responsible for creating energy, account for more than 7% of patients with a mitochondrial disease manifesting itself as a respiratory deficiency.

Vegetable oil is good for you, experts say Posted: 07 Jun 2013 07:28 PM PDT Since the 1970s, researchers have known that lineolic acid (LA) helps reduce blood cholesterol levels, and for decades, scientists have known that consuming LA can help lower the risk of heart disease. However, some experts have been claiming recently that Americans might be getting too much of a good thing. A new study contradicts that claim.

Significant under-use of genetic testing for inherited cancers puts health of entire families at risk Posted: 07 Jun 2013 07:25 PM PDT French researchers who carried out the first-ever national study of the take-up of genetic testing for BRCA1 and 2 and MMR (Lynch syndrome) mutations have found that, although there had been a steady increase in tests performed for the cancer-causing mutations BRCA1 and BRCA2, this was not the case with the MMR mutation, where the numbers undergoing the test are still tiny. Only a third of relatives of individuals with either mutation underwent genetic testing themselves.
