Road may disrupt migration, ruin Serengeti, study finds
Building a highway through Serengeti National Park may devastate one of the world’s last large-scale herd migrations and the region’s ecosystem, according to new research by an international team of ecologists, including a University of Guelph prof…
Satellite data reveal why migrating birds have a small window to spread bird flu
In 2005 an outbreak of the H5N1 ‘bird flu’ virus in South East Asia led to widespread fear with predictions that the intercontinental migration of wild birds could lead to global pandemic. Such fears were never realised, and now research published i…

Researchers identify a gene responsible for spread of cancer in the body
Researchers have identified a gene that promotes metastases, the spread of cancer cells through the body. This new understanding of how cancer metastasizes, linking a gene product and migration of cancer cells, may lead to therapies to stop this spread. The results of the study are published in the May 2003 issue of the journal Molecular Biology of the Cell. Richard G. Pestell, M.D., Ph.D. and his research team have been studying the cyclin D1 gene and the protein it produces for the past decade. Now they have found that by “knocking out” this gene, the migration of cells can be halted. The migration of cancer cells through the body is a major reason why cancer is deadly.
