Health and Nutrition Women with low body iron, yet who are not anemic, have a much harder time sustaining exercise and adapting to training, concludes a new Cornell University study. Iron deficiency that is not as severe as anemia is a common problem, affecting about 16 percent of U.S. women and 40 to 80 percent of women in developing countries, most of whom are unaware of their condition. Other researchers have reported recently that moderate iron deficiency also compromises memory and verbal learning in teen-agers. In a previous study, published in 1998, Haas found that iron-depletion in nonanemic women results in lower capacity for physical work and impaired exercise performance. Human immunity to a virus has been triggered for the first time by a vaccine genetically engineered into a potato .
Potatoes are only a prototype for delivering plant-based vaccines.
A tasty vaccine-containing food, particularly bananas, a favorite food among children, could be inexpensive and plentiful. It conducts research on plant biology and continues the tradition of using science and technology to protect the environment and improve human health and well-being. In 1998, more than 20 million computers became obsolete and unwanted in America, according to a study by the National Safety Council. At that rate, by 2005, some 55 million computers a year could be discarded in landfills. One of the toughest nuts to crack to make computers recyclable is the circuit board, where components worth hundreds of dollars apiece are soldered in place then further secured with a protective adhesive, such as an epoxy compound.
