Manufacturers have promoted genetically engineered soybeans that can withstand sprayings with glyphosate herbicide. However, Marc Lappé of the Center for Ethics and Toxics of Gualala, Calif., recently found "herbicide-tolerant" soybeans to be 12 to 14 percent lower in cancer-fighting phytoestrogens, compared to normal soybeans. It is not clear whether the change in nutritional value is due to genetic alteration, herbicide use, or both. Dairy Industry Targets China
Meanwhile, 500 Beijing students will be enrolled in the School Milk Supplementation Trial, a Chinese-Australian research project that aims to show the health benefits of milk. Ironically, osteoporosis is much more prevalent in North America and Scandinavia, where milk consumption is much more common. Chronic health problems are expected to rise as animal products increase in Asian diets. Dog Uninjured in Incident
Spam Stock Plummets The advent of fire advanced the intelligence and culture of early humans, not because it permitted them to cook meat, but because it expanded their range of edible plants, say Gregory Laden of the University of Minnesota and Richard Wrangham of Harvard. Their work in Kenya suggests that humans have used fire for 1.9 million years, much longer than the 200,000 to 500,000 years previously estimated. Fire does not alter the available caloric content of meat but greatly alters the nutrition available from root vegetables and other plants. Their findings are presented in the December 1999 Current Anthropology. Monkeys Have Better Eating Habits Than Humans
Andrew Jackson Had Lead Poisoning? Andrew Jacksons persistent abdominal cramps, constipation, and extremity pains may have been caused by lead poisoning, according to pathologist Ludwig M. Deppisch, who analyzed hair samples from 1815 and 1839. The likely sources were a bullet in his left shoulder acquired during a gunfight in 1913 and not removed until 1932 and a second bullet in his lung that was never removed. Lets Make This Relationship Work University of Iowa researchers tested the theory that the loss of a symbiotic relationship with intestinal parasites may be partly to blame for inflammatory bowel disease. They fed six suffering, yet courageous, volunteers parasite eggs and found that two to three weeks later, five of the six were symptom-free. Theres Always Room for Veg-ello
New Microsurgical Trainer Rats are often used by surgeons practicing their microsurgical skills. A new latex simulator, PVC-Rat, allows careful practice in reconnecting arteries and nerves, without the use of animals. PVC-Rat is manufactured by Belgium-based Solvay Pharmaceuticals. It was designed by Microsurgical Developments (P.O. Box 2045, 6201CC, Maastricht, Netherlands; www.microdev.nl). TOP PHOTO: © 1999, PHOTODISC |
