Scientists who think that children learn aggressive behaviour from TV also emphasise that parents have the power over what their children watch. Because of this, many scientists recommend a number of things that parents can do. Reduce the amount of hours of TV that your children watch, watch at least one episode of the shows your children watch, and when they see a violent act on the show that their children are watching, discuss it with your child and tell them that this kind of behaviour is not good and not the way to solve problems.

Looking ahead from the present position where food production has kept ahead of population growth globally, but has fallen per capita in 55 (mainly African) countries, it would seem that these trends will continue. About 30 countries - most of them African - can expect serious problems unless they reduce population growth and give higher priority to agriculture and conservation. Though a warmer, wetter earth with high CO2 levels is likely to be capable of producing more food, the amounts will still be inadequate for many poorer countries. In many cases, the population projections are greater than the entire local land resources can support.

The author E. L. Doctorow is best known for mixing fiction with historical fact, by placing his stories within the frame work of public events, in fact by integrating the front-page news of 20th century America with the lives of his characters. Doctorow gives readers the "feel" of an era combining the unusual and the commonplace. His latest novel World's Fair shows how the events of the turbulent 1930s helped mould the sensibilities of his young protagonist.

Ever since Nobel prize-winner Linus Pauling first advocated vitamin C as a common-cold war weapon more than 20 years ago, researchers have been busy trying to verify that claim. But so far, they've found little proof that vitamin C prevents colds. In fact, there are more studies that say it doesn't. But there is evidence that it can keep coughing and sneezing to a minimum, and that low levels of vitamin C in the body may be related to bronchitis.

Since early times it has been assumed that the actions of animals are unconscious. Behaviour, in this view, stems almost exclusively from instinct. If animals behave in ways that seems pretty clever, they do so without thinking about it. Animals may know things, the argument goes, but that they know that they know. Current research reports suggest a startling depth of intelligence among animals. Although no one can yet 'prove' the existence of animal consciousness, the data offered make a compelling case for at least considering it.

The first universities developed in Europe in the 12th century. By 1600 Western Europe boasted 108 institutions of higher learning, many of which had obtained special privileges from existing regimes because of their close association with the Church. In most European countries universities were designed mainly for the sons of nobility and gentry. Scholarly standards were low, and scholarship was irrelevant for most professions. Education for earning a livelihood in, say, medicine or law could be acquired after college by serving as an apprentice.
