Rolling spheres

Muhammad Rizwanur Rahman
The bigger they are the faster they roll…or so we thought. Droplets that are larger than a ‘characteristic size’ will roll more slowly than smaller droplets. This work has far reaching consequences for applications in many fields of engineering and science.

ancient forks in evolutionary roads

Gianni M. Castiglione, Ph.D. Why didn’t land animals evolve high dim-light sensitivity like deep-sea fishes? New research suggests these ancient evolutionary roads were closed because of an increased risk of eye disease.

Canadian Think Tanks and Idea Generation

Osman Naqvi, M.Mgt. Translating academic research into public policy requires assumptions. Government officials often make decisions based on the advice of think tanks: private firms that help generate public policy using data analysis.

Interactions between Listeria and Food

Stephanie M. Prezioso, Ph.D. The bacteria Listeria monocytogenes contaminates a variety of meat and plant-based food products. Listeria can use a host plant’s molecules in its own metabolism, and this works differently compared to other species.

High-Altitude vision

Gianni Castiglione, Ph.D.  Human vision is only possible because of Rhodopsin- a special light-sensitive protein in your retina. New research shows that rhodopsin and the visual system also adapt to changes in temperature.

Gene Regulation

Stephanie M. Prezioso, Ph.D. A positive feedback loop is the melting of the polar ice caps: as the ice melts, there is less reflection of solar energy, and further melting. A similar feedback loop exists at the molecular level in the bacteria Pseudomonas putida.

The Retina

Gianni Castiglione, Ph.D. All vertebrate eyes share a remarkable level of common detail, the most basic of which are its functions to transmit and focus light onto the retina- an incredibly dense nerve cell layer at the back of the eye that acts as a light receiver.
