The study looks at the effects of imposing a sugar tax in four American cities, the Catalonia region of Spain, and country-wide in Chile, France and Mexico.  Kathryn Ryan speaks with lead author Dr Andrea Teng, a public health physician and senior researcher at the University of Otago.  The review has just been published in international scientific journal, Obesity Reviews.

Pioneering geneticist Dr Ron Davis with researchers at Stanford University thinks he may have discovered a blood test that can flag chronic fatigue syndrome (CFS) / Myalgic encephalomyelitis (ME). If so it would be the breakthrough that sufferers have been seeking for decades - proof that it exists. While not much is known about CFS many sufferers complain that their condition is often regarded as imaginary, in part due to there being no test for it. Currently a diagnosis is based on the appearance of symptoms like extreme exhaustion, sensitivity to light and unexplained pain. In New Zealand it's estimated that there are around 20 thousand people with chronic fatigue syndrome. Dr Ron Davis is the Director of the Stanford Genome Technology Center with a personal reason to find a cure as his 35 year old son Whitney suffers from a debilitating form of the disease.
