Power and predatory sexual behaviour
My elitist, boys secondary school education encouraged competitiveness and dominance. As an impressionable young man, my “rite of passage” transgressions caught up with me and so I learnt the error of my ways. The males of our species are naturally predatory which has led to social exploitation, with the upwardly mobile using and abusing those who have less power.

A Mason Engineering researcher has discovered that artificial microswimmers accumulate where their speed is minimized, an idea that could have implications for improving the efficacy of targeted cancer therapy.
Jeff Moran, an assistant professor of mechanical engineering in the Volgenau School of Engineering, and colleagues from the University of Washington in Seattle studied self-propelled half-platinum/half-gold rods that swim in water using hydrogen peroxide as a fuel. The more peroxide there is, the faster the swimming; without peroxide in pure water, the rods don t swim.
In this work, they set out to understand what happens when these artificial microswimmers are placed in a fluid reservoir containing a gradient of hydrogen peroxide lots of peroxide on one side, not much on the other side.
