Low-level toxin in drinking water can alter stem cells

World-first research at the University of Adelaide has found that even low levels of a common toxin in drinking water are enough to cause problems in developing brain cells - but there's no cause for alarm for Australia's water drinkers just yet. For her PhD in the University's School of Medical Sciences, Katie O'Neill is conducting laboratory studies to see what happens when apparently "safe" levels of the water-borne toxin known as saxitoxin come in contact with model brain cells .
