Voluntary Initiative, Born Out of WSSD, Set to Deliver Major Health and Environmental Benefits to Continent’s 800 Million Citizens
UNEP’s Governing Council 3 to 7 February: Environment for Development
An international effort to phase out lead, the health-hazardous heavy metal, from petrol is accelerating as increasing numbers of African countries switch to unleaded fuel.

The scientists have not yet found the limits of the monkeys’ learning capacity
Psychologists have found evidence that monkeys have sophisticated abilities to acquire and apply knowledge using some of the same strategies as do humans. Specifically, the researchers have discovered that rhesus monkeys can learn the correct order of arbitrary sets of images and can apply that knowledge to answer new questions about that order.
Not only can the monkeys choose which image came f
Global Positioning Systems prepare a digital map for precise soil acidity identification
A study conducted by Iowa State University soil scientists suggests Global Positioning Systems (GPS) available to corn and soybean producers can markedly improve the management of soil acidity and lime application. The research is published in the January/February 2003 issue of Agronomy Journal.
Soil acidity can limit plant growth, and due to soil formation processes and management pract
UF researchers report: Immunosuppressant drug prevents late rejection of transplanted kidneys
A drug that suppresses the immune system and prolongs the survival of donated kidneys in patients in the first months after transplantation also has the ability to block organ rejection over the long haul, University of Florida researchers have found.
The drug, mycophenolate mofetil, has been shown to decrease acute rejection by 50 percent compared with an older agent commonly used,
Opens new door to study of mood disorders in humans
Researchers report finding a gene that is essential for normal levels of anxiety and aggression. Calling it the Pet-1 gene, researchers at the Case Western Reserve University School of Medicine Department of Neurosciences say that when this gene is removed or “knocked out” in a mouse, aggression and anxiety in adults are greatly elevated compared to a control (also called wild type) mouse.
(Videos displaying aggressive beha
Employing high-tech, digital X-ray microtomography (microCT), Northwestern University scientists have discovered the way in which newts form new bone and cartilage during limb regeneration. Newts are a type of salamander, the only vertebrates capable of rebuilding lost structures such as limbs throughout their lifetimes.
Reporting in the January issue of Developmental Dynamics, Northwestern researchers Hans-Georg Simon and Stuart Stock showed that bone formation in a regenerated forelimb co
