ancient forks in evolutionary roads

Gianni M. Castiglione, Ph.D. Like deep-sea fishes, dim-light sensitivity in land animals could have been heightened, yet this never evolved. New research suggests these ancient evolutionary roads were closed because of an increased risk of eye disease.

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.

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.

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.

Canadian Think Tanks and Idea Generation

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

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.
