Cloud computing method greatly increases gene analysis
— 12:00 GMT | HealthResearchers at the Johns Hopkins Bloomberg School of Public Health have developed new software that greatly improves the speed at which scientists can analyse RNA sequencing data. RNA sequencing is used to compare differences in gene expression to identify those genes that switched on or off when, for instance, a particular disease is present. However, sequencing instruments can produce billions of sequences per day, which can be time-consuming and costly to analyse. The software, known as Myrna, uses 'cloud computing,' an Internet-based method of sharing computer resources. Faster, cost-effective analysis of gene expression could be a valuable tool in understanding the genetic causes of disease…
Researchers identify genes tied to deadliest ovarian cancers

ADA supports national restaurant menu labelling legislation
— 11:54 GMT | HealthThe government's role in improving the nation's nutrition is now firmly established with nutritional labelling for restaurant meals now mandated across the United States as part of HR 3590 Patient Protection and Affordable Health Care Act. An article in the September issue of the Journal of the American Dietetic Association explains how state and municipal labelling laws developed and how the new national law will supersede these and replace them with a uniform standard. It also addresses the American Dietetic Association's (ADA's) involvement and how these new regulations will impact registered dieticians (RDs) and dietetic technicians, registered (DTRs) as well as consumers…
