Genetic engineering, often slammed by environmental and consumer groups for its role in altering staple foods, may have found a niche where it can help save the lives of millions from the world's most endemic diseases.
By using biotechnology to incorporate useful genes into an almost limitless variety of common plants, from rapeseed and tobacco to potato, tomato and banana, scientists aim to produce cheap and stable vaccines in an edible form -- and beat disease.

Space, the last frontier remaining to be truly explored and exploited by man. Vast mineral riches are believed to lie in its cold depths, especially on the moon -- an untapped resource just waiting for its first commercial landing.
