iochemical and kinetic studies have failed to provide a unified view on how the Arp2/3 complex nucleates actin filaments. Does the complex, which mediates actin filament nucleation and branch formation at the leading edge of motile cells, bind to the side of an older actin filament, or does it become incorporated into that filament? B Structural studies now add a new dimension to the discourse,...

I n th i s co m memorative issue of Canadian Family Physician, celebrating 50 years of postponed extinction, we present a snapshot of practice and the times du...

Predicting bird song from space

Environmentally imposed selection pressures are well known to shape animal signals. Changes in these signals can result in recognition mismatches between individuals living in different habitats, leading to reproductive divergence and speciation. For example, numerous studies have shown that differences in avian song may be a potent prezygotic isolating mechanism. Typically, however, detailed s...

Response to Heard et al.

H eard et al (2015) generated cIap1 / Xiap / mice and were surprised to find them to be viable and fertile, because we had reported (Moulin et al, 2012) that cIap1 / Xiap / mice died by day E12.5 of embryogenesis (Moulin et al, 2012 Figs 1B and 2B and Supplementary Fig S1A). We are working with Heard et al (2015) in an attempt to determine why. It is, however, clear that failure of our cIap2cIa...
