This article focuses on the health aspects of aspartame. Aspartame, also known in Europe as E951, is the artificial sweetener people love to hate. Since it was approved for food use 25 years ago it has been linked to pretty much every health scare going, from brain tumours to insomnia and mood swings. In 2005 a group of scientists at the European Ramazzini Foundation in Bentivoglio, near Bologna in Italy, published some new findings. When the foundation's researchers added aspartame to the diet of 1500 rats, they saw an increase in the incidence of leukaemias and lymphomas, cancers of the blood and lymphatic systems, particularly among females. Notably, cancer incidence rose even in rats fed the equivalent of half the World Health Organization's acceptable daily intake of 40 milligrams of aspartame per kilogram of body weight.

The article discusses consumption and harmful effects of caffeine. Caffeine is the most widely consumed psychoactive substance on earth, prized by almost every human culture for its ability to perk people up and keep them awake. In North America, around 90 per cent of adults report using caffeine every day. Caffeine bashing started in earnest in the mid-1970s when several major studies linked it with heart disease and bladder cancer. Perhaps the most notorious study came in 1980 when Thomas Collins of the US Food and Drug Administration (FDA) linked caffeine to birth defects in rats. The study sent shock waves through the drinks industry and led the FDA to warn pregnant women to cut down on coffee and tea. INSET: Caffeine cheats?.

The article discusses issues related to the freezing of the crater of Mount Saint Helens, Washington. Adventurer Charlie Anderson has been in the crater of Mount St Helens more times than anyone else. He was one of the few people who weren't surprised when geologists announced that in the time since its 1980 eruption, North America's most famous volcano has grown a full-fledged glacier in its crater. Anderson predicted in 1982, that a glacier would grow beneath those shady slopes. But in its early years, the crater was rocked by eruptions that gradually created a 270-metre-high lava dome in its centre.
