Cold viruses activate killer genes, study finds
Oct. 24, 2008
WASHINGTON (Reuters) - The common cold virus activates dozens of immune system genes in the lining of the nose, including some natural antivirals that might be used as the basis of new drugs, researchers reported on Friday.
It also appears to shut down some genes, but to a lesser degree, the international team reported in the American Journal of Respiratory and Critical Care Medicine.
Of particular interest is a gene that controls a natural antiviral called viperin, said David Proud of the University of Calgary in Alberta, who led the study.

Pollution linked to appendicitis
Oct. 6, 2008
If the appendix becomes inflammed it must be removed surgically to avoid the risk that it will burst, and put the patient's life at risk.
A University of Calgary team found more patients were hospitalised on days when pollution levels were at their highest.
The study, presented to an American College of Gastroenterology conference, suggests pollution raises the general risk of tissue inflammation.

A Better CO2 Scrubber
Oct. 1, 2008
Around half of our CO2 emissions aren’t from big power plants, or even small power plants, according to researchers from the University of Calgary. They’re from diffuse sources, like car exhaust, home heating and airplanes, which can’t be easily sucked up at the source. Led by climate scientist David Keith, the Calgary group is working on technology that could soak those “diffuse emissions” right out of the air.
