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 practices, there exists large pH variability within producers’ fields. Lime often needs to be applied to maintain profitable crop production; however, traditional methods make it impractical to change lime application rates over a field. Producers usually apply a uniform rate although they recognize only a small proportion of the field receives the optimum application.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
