In microbiology, a “movie” makes all the difference, between seeing everything at the molecular level, and seeing very little.

So says University of Guelph Prof. Cezar Khursigara, who’s seeing more than ever these days thanks to a new spinning disk confocal microscope recently acquired by Khursigara, and colleagues Joseph Lam and Chris Whitfield in the Department of Molecular and Cellular Biology. It’s opening up new research possibilities Khursigara and his colleagues previously only dreamt of.

A plant-based alternative to emu oil, a skin-softening ingredient in cosmetics and hand lotion, is being developed at the University of Guelph.

Prof. Alejandro Marangoni, from the Department of Food Science and a leading expert on fats and oils, was approached by Avaria Health and Beauty Corporation of Waterloo, Ontario to create cosmetics that are emu oil-free.

Avaria, a privately owned business, focuses on natural merchandise and wants to create a line of 100 per cent plant-based products. One of its most popular...

New non-toxic technique causes self-destruction of cancer cells

A new, non-toxic treatment applicable to a broad range of cancers may change the way we look at cancer therapy, says a University of Guelph researcher.

Prof. Jim Uniacke, Department of Molecular and Cellular Biology, is studying tumour hypoxia, a condition where a tumour cell has been deprived of oxygen.

It’s found in individuals with diseases such as cancer or heart disease. As the hypoxic tumours grow, they deplete the available blood supply around them, leading to a lack of oxygen.

This physiology of tumour hypoxia...

By Alexandra Sawatzky

Tree nurseries are some of the largest consumers of irrigation water in Ontario’s ornamental horticulture sector. And although many are keen to develop ways of mitigating the environmental impact and cost of excessive water use, improved irrigation management strategies are elusive. They’re confounded by multiple factors - including supply and demand for moisture - that affect the relationship between a plant and its environment in an integrated fashion.

Prof. Mike Dixon of the School of Environmental Sciences...

An effective, non-invasive and inexpensive method for diagnosing the nasal tumour-causing virus in sheep and goats has been developed at the University of Guelph.

The virus, known as enzootic nasal tumor virus (ENTV -1), has been the target of Prof. Sarah Wootton and her University of Guelph colleagues.

They studied a flock of 80 horned Dorset sheep with a history of Enzootic nasal adenocarcinoma in Ontario throughout 2014. Wootton developed a diagnostic technique, known as...
