Melting crust makes rich gold, copper deposits

A U of T study suggests why giant gold and copper deposits are found at some volcanoes but not others, a finding that could point prospectors to large deposits of this and other valuable metals.

“There’s one characteristic that is common to all of these big gold and copper deposits anywhere in the world,” says Professor James Mungall of the Department of Geology. The ocean’s crust that is pushed down under a volcano can start to melt, which it doesn’t normally do. His study, which appea

Geneticists tell ostrich farmers the secrets of sex

Research published in the online journal, BMC Biotechnology reports on a new, large-scale technique for distinguishing between male and female ostrich chicks using DNA extracted from feathers. This new technique will remove the need for invasive procedures currently in use to sex-type ostriches and allow breeders to discover the sex of their chicks much earlier. Details of this new technique can now be read by all interested parties because of the decision of the authors to publish in the open access

Maedi-Visna, Aids of sheep

The disorder Maedi-Visna that is detected in sheep affects on mammary gland. As it says in the source language, Icelander, it affects lungs and nervous system. The disorder is produced by the lentivirus Maedi-Visna, which belongs to the family of Aids. This virus infects sheep, and until now, there is no evidence of the transmission to humans. This virus, which is known since many years, causes a very slow evolution of the disorder. Therefore, shepherds often do not detect the infection, because shee

Natural insecticide identified as potential cancer prevention agent for early stage lung cancer

Deguelin may inhibit growth of Akt, an essential molecule in the promotion of precancer

The use of deguelin, a natural plant extract most commonly used as an insecticide in Africa and South American, inhibits the growth of precancerous and cancerous lung cells, with no toxic effects on normal cells, according to a study presented today at the first annual Frontiers in Cancer Prevention Research meeting convened by the American Association for Cancer Research. The role of deguelin as a

Immediate treatment helps delay progression of glaucoma

Researchers have found that immediately treating people who have early stage glaucoma can delay progression of the disease. This finding supports the medical community’s emerging consensus that treatment to lower pressure inside the eye can slow glaucoma damage and subsequent vision loss. These results are reported in the October 2002 issue of Archives of Ophthalmology.

Scientists found that immediate treatment of newly-discovered primary open-angle glaucoma, the most common form of glaucoma

UCLA neuroscientists discovery distinct molecular key to overcoming fear

In a discovery with implications for treatment of anxiety disorders, UCLA Neuropsychiatric Institute investigators have identified a distinct molecular process in the brain involved in overcoming fear. The findings will be published in the Oct. 15 edition of the Journal of Neuroscience .

The study of how mice acquire, express and extinguish conditional fear shows for the first time that L-type voltage-gated calcium channels (LVGCCs) — one of hundreds of
