Trials in a two-way chemistry

Article Abstract:

Pharmaceutical firms are criticized by some university professors in Tanzania for failing to use local expertise in plant knowledge when researching the use of plants for medicines. The firms are called upon to form fair collaborative deals which allow the universities to apply their knowledge and make a profit while training botanists. African plants provide a wealth of resources for the potential development of new insecticides and drugs. African children should simultaneously be educated in the field rather than taught botany from textbooks to prevent expertise from disappearing.

Reasons to be fearful

Article Abstract:

There is increasing concern about health hazards from contaminated wastes in the US, despite evidence that the population is healthy. This paradox has led to a study of how the public perceives risk. Objective views on risk are difficult to obtain since there are many aspects of risk to be examined. Public perception of risk tends to be influence by whether the risk is long term, and whether the risk factor involves personal experience. White men tend to perceive less risk than white women and men and women from non-white groups.

Age of genetic utopia

Article Abstract:

Humankind is less at risk from mutations since there are fewer older parents, and older parents are more likely to have children with mutations, according to Steve Jones from University College, London, England. Natural selection is no longer important, but more men have a chance to father children than in primitive societies. Inbreeding has also become less of a problem since people tend to marry outside their community.
