New scientific evidence is helping to build a compelling case for oncolytic viruses as a first-line and adjunctive treatment for many cancers.

Reovirus, a non-pathogenic virus under development at Calgary, Alberta-based Oncolytics Biotech, has shown powerful anti-cancer activity against cultured tumor cells, in animal models, and in human clinical trials. Oncolytics' proprietary reovirus formulation, Reolysin®, is active against numerous cancers, including intractable sarcomas and melanomas.

Travellers have relied on accurate timekeeping for navigation since the development of the marine chronometer in the eighteenth century. Galileo, Europe’s twenty-first century navigation system, also relies on clocks – but they are millions of times more accurate than those earlier timepieces.

The operational Galileo satellites will carry two types of clocks – passive hydrogen masers and rubidium atomic frequency standards.

A novel catheter technique for patching holes in the heart may make it possible for many patients to avoid surgery altogether and others to regain enough strength to safely undergo surgical repair at a later date.

The patch successfully closed ventricular septal defects (VSDs)—or ruptures in the wall between the right and left ventricles—in nearly all patients, allowing blood to circulate normally again and relieving fluid back-up in the lungs. After recovery, patients were able to return to active lives.

Drinking farm milk can protect children against asthma and hayfever, according to a study of nearly 15,000 children published in the May issue of Clinical and Experimental Allergy.

But consuming farm milk that hasn’t been boiled may pose health risks and further research is needed to develop a safe product that still provides good protection against these common childhood diseases.

Collaborating with scientists in the United States and from around the world, Mengshi Lin, assistant professor of food science in the College of Agriculture, Food and Natural Resources, has successfully used a new approach combining DNA sequencing technique with mid-infrared spectroscopy to rapidly and accurately identify Alicyclobacillus, a common bacterium found in apple, carrot, tomato, orange and pear juices, tropical fruit juices and juice blends. The bacterium won't cause human sickness, but it affects flavor and results in spoilage.

The majority of advertising exposure occurs when the audience’s attention is focused elsewhere, such as while flipping through a magazine or browsing a web site. However, a new study reveals that even this incidental exposure to advertising may have a positive effect on consumer attitudes. Forthcoming in the June issue of the Journal of Consumer Research, the study revises existing theories of exposure advertising, specifically repeated views of web-based banner ads.
