Although quinoa is widely regarded by foodies as an up-and-coming superfood, this nutrition-packed grain is currently grown only in South America’s Andes Mountains. As Canadian tastes and markets for this...
Read More >>How convenient it would be if we could convince a torn piece of material to return to its undamaged state. Université de Sherbrooke chemist Yue Zhao has been able to purchase just such convenience with some vanishingly small amounts of gold. The substance in question is gold nanoparticles or nanorods, which are inserted into a thin...

Read More >>Mollusc shells consist largely of chalk, the same soft stuff that comes apart so easily on blackboards. Yet this material provides aquatic life with protection tougher than advanced engineering ceramics. The difference can be seen at the microscopic level, where the shell is revealed as an interlocking series of small tablets, intricately connected to provide remarkable resilience.
Read More >>The extraordinary properties of superconductivity have regularly frustrated researchers, who have successfully identified it in many different materials, but always at temperatures too low for a widespread technological impact. The search for superconducting materials — which lack any resistance to electrical flow — has regularly frustrated researchers; while many such materials have been discovered, they only work at temperatures too low for widespread application.
Read More >>A handheld system developed through an India-Canada research network promises to provide on-the-spot testing of drinking water sources in more remote locations, immediately confirming the absence or presence of harmful E. coli bacteria and transmitting the results electronically to all interested parties. This approach represents a significant improvement over standard...
Read More >>The best way of applying medicines powerful enough to kill cancerous tumours is to ensure that they wind up in those tumours and nowhere else in the body. In a recent Nature Nanotechnology paper, researchers at the University of Toronto point the way to just this kind of targeted delivery, which takes advantage of the properties of gold nanoparticles.

Read More >>While untold numbers of plants have carried out photosynthesis for hundreds of millions of years, the nature of this subtle process continues to elude us. Scientists are, however, focusing increasingly sophisticated tools on this problem, raising hopes that this fundamental biological activity will eventually reveal its secrets.
Read More >>Three researchers at Polytechnique Montréal have published a paper that was featured as the cover story for the Wiley publication Small, which has an impact factor that puts it among the world’s leading publications covering topics in nano-scale and micro-scale chemistry, physics, materials science, engineering, medicine and biology.
