9:06 PM | Hierarchical competition and the ethology of sexual dimorphism in humans
In most animals, males are the ones who dispute the group supremacy and fight for a high hierarchical position that grants them more resources and access to females. Because the genes of the most powerful and aggressive males pass on from one generation to another, the new generations of males are, at their turn, aggressive […] The post Hierarchical competition and the ethology of sexual dimorphism in humans appeared first on Social Ethology.

4:26 PM | The increasing importance of distinguishing among plant nitrogen sources
Many studies of plant nitrogen relations assess only the total amount of the element available from the soil and the total amount of the element within the plant. Nitrogen, however, is a constituent of diverse compounds that participate in some of the most energy-intensive reactions in the biosphere. The following characterizes some of these reactions, especially those that involve ammonium and nitrate, and highlights the importance of distinguishing both among the nitrogen sources available to […]

High Reynold's number (~3900) from large eddy simulation: no laminar flow http://www6.miami.edu/acfdlab/CFD.html“Reynold’s number” (Re) describes the ratio between forces of inertia and viscosity in discussions of fluid mechanics. Re = (V·d·ρ) / μ As shown in the formula above, Reynold’s number scales this ratio of density (ρ) to viscosity (μ) by speed of flow through (V), and diameter (d) of the fluid container (e.g. a pipe). These factors […]

And for someone who has been such a strong supporter of evidence, even famously noting in his debate with creationist Ken Ham what would change is mind on a topic: Those of us who support evidence-based […]

It’s well known that an itch can be contagious – seeing a person scratch can make you want to do the same. But why does this happen? Dr Emily Grossman explains that it might be a mechanism for preventing the spread of parasitic diseases in close-nit social groups. Social itching is likely prompted by the interplay […]
