FRONTIER CENTRE: In August the National Post published a provocative article in which you argue that Canada's rate of economic growth could out pace the impressive American rate and that Canada's standard of living could surpass that of our American cousins within twenty years should we adopt certain changes in public policy. Wouldn't such an about face, in fact, restore the Canadian advantage?...

There are three parts of this broad agenda. The first relates to understanding how investors obtain and process information about firms. For a long time, the question of how investors receive information was either abstracted away from entirely (e.g. by assuming signals are received by all investors instantaneously), or modeled at a very high level (e.g. information diffuses slowly among invest...

David McClay is the Arthur S. Pearse Professor of Biology at Trinity College of Arts and Sciences, Duke University, North Carolina. His lab works on the transcriptional control of morphogenesis in the sea urchin embryo. We caught up with David at the 2016 Society for Developmental Biology - International Society of Differentiation joint meeting in Boston, where he received the Lifetime Achievem...

As the incidence of inflammatory disease and food allergies increases in the industrialized world, David Artis wonders if something is wrong with the little friends in our guts.

T wo decades ago, David Mangelsdorf did not expect his basic research findings to help launch an entire field of biology with farreaching implications for a raft of human diseases, including cancer, metabolic disorders, and parasitic infections. Mangelsdorf, a Howard Hughes Medical Institute investigator and a professor of pharmacology at the University of Texas Southwestern Medical Center at D...

David maps are generalizations of classical planar quasiconformal maps for which the dilatation is allowed to tend to infinity in a controlled fashion. In this note we examine how these maps distort Hausdorff dimension. We show: – Given α and β in [0, 2] , there exists a David map φ: C → C and a compact set Λ such that dimH Λ = α and dimH φ(Λ) = β . – There exists a David map φ: C → C such that...

David T. Yue David Tuckchow Yue, a renowned biophysicist who dedicated his life to the study of voltage-gated calcium (CaV) channels, passed away suddenly on December 23, 2014 from cardiac arrest. David was a passionate, dedicated, and brilliant scientist who pursued fundamental mechanistic understanding of CaV channel regulation with quantitative rigor, child-like wonder, and remarkable creati...

I’ve never had a response to a column quite like that to Keeping Older Doctors in the Job. As well as several public rapid responses, including an inspirational paean to rural general practice from Dr James Douglas, I received over 100 private emails. I calculate the median respondent’s age as 68. Others replied on Twitter to #olderdoctors. My respondents weren’t a scientifically constructed sa...

As a young doctoral candidate at the Johns Hopkins University School of Medicine, David M. Sabatini was allowed to choose his own research project for his thesis. He chose to investigate the molecular mechanism of rapamycin, a compound with antifungal, antitumor, and immunosuppressant properties. The decision was pivotal, because Sabatini went on to discover the mechanistic target of rapamycin ...
