Aussie Scientists Make Diabetes Breakthrough

Australian researchers have pinpointed a key cause of type 2 diabetes, in a study they say has brought them closer to developing a simpler, more effective treatment for the disease.

The scientists at Sydney's Garvan Insititute say their discovery is a major step forward in the treatment of the disease, which affects about 7 per cent of Australia's population.

The team has identified an enzyme in diabetics as the active agent that blocks the production of insulin, which is a hormone that helps the pancreas convert blood-sugar into energy.
