Females' regenerating advantage

Females' regenerating advantage

M en might build more muscle, but women are better at keeping what they have, if results from Deasy et al. (page 73) are any indication. The group shows that female muscle stem cells are better than their male counterparts at regenerating lost muscle. The authors were led into the realm of muscle and sex when they realized that they were relying heavily on cell lines derived from female mice to...

The Evolution of Large Body Size in Females: a Critique of Darwin's "fecundity Advantage" Model

In most species of animals, females attain larger body sizes than do males. This generality was established for many groups (e.g., spiders, insects, fishes, amphibians, reptiles) by Darwin (1874), and it has been supported and extended by many subsequent workers. Even for taxa such as mammals and birds, in which males frequently are the larger sex, there are many examples of greater size in fem...

Regenerating Wnts

Research in recent years challenged what we once thought of as the canonical function of signaling proteins to reveal new and surprising mechanisms of action. Morphogens, like Wnts, BMPs, or SHHs, long thought to be the factors that provide positional information to specify cell fate and proliferation have turned out to be as important for synaptogenesis, axonal growth, and guidance during both...

Comparative Advantage and Competitive Advantage:

There is a considerable amount of controversy about the model(s) of comparative advantage and its applicability to international business, in particular as a guide to the success of nations and/or firms in international markets. This perception (or understanding) of inapplicability of the model(s) of comparative advantage has lead international business experts to develop new models, or what ma...
